Question 1

HOTSPOT -
You have a Microsoft Teams Phone deployment that contains a Session Border Controller (SBC) named SBC1.contoso.com.
Direct Routing integrates with a PBX phone system that uses only four-digit dialing and is configured to use the SBC.
Teams is configured to use dial plans that normalize any four-digit calls to E.164.
You have the following translation rule.

You need to ensure that calls to the legacy PBX pass only a four-digit extension.
How should you complete the PowerShell command? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer: See interactive view.

Explanation:

The AI assistant agrees with the suggested answer.

Reasoning:
The scenario describes a Microsoft Teams Phone deployment integrated with a legacy PBX via Direct Routing. Key points are:

Teams dial plans are configured to normalize any four-digit calls (e.g., '1234') to E.164 format (e.g., '+12065551234' assuming a North American numbering plan).
The legacy PBX, however, is configured to accept and work with only four-digit extensions (e.g., '1234').
The objective is to ensure that calls originating from Teams, destined for the legacy PBX through the Session Border Controller (SBC1.contoso.com), are translated from their E.164 format back to the required four-digit extension format before being passed to the PBX.

This type of outbound number translation is a critical function in Microsoft Teams Direct Routing. It is primarily achieved by defining a translation rule within an Online PSTN Usage, which is then associated with an Online Voice Route that directs calls to the specific SBC connected to the legacy PBX.

The PowerShell command to accomplish this involves modifying an existing PSTN usage or defining a new one. The Set-CsOnlinePstnUsage cmdlet is used to update the properties of an existing PSTN usage, and within this cmdlet, specific translation rules can be added or defined using New-CsPSTNTranslationRule.

The translation rule must define a -Pattern that matches the E.164 number format as sent by Teams, and a -Translation that specifies how to transform that matched number. For the scenario where a four-digit extension (e.g., '1234') is normalized to an 11-digit E.164 number (e.g., '+12065551234'), the rule needs to strip the initial E.164 country code, area code, and exchange, leaving only the final four digits.
A common regex pattern for this is "^\+1\d{7}(\d{4})$", which matches an E.164 number starting with `+1`, followed by exactly seven digits, and then captures the final four digits. The corresponding -Translation "$1" then uses the captured four digits as the output. This ensures that only the required four-digit extension is passed to the legacy PBX.

Therefore, the PowerShell command would involve configuring the appropriate Set-CsOnlinePstnUsage with a New-CsPSTNTranslationRule that includes the correct -Pattern and -Translation to achieve the desired four-digit output.

The discussion summary further affirms the correctness of the suggested answer, indicating a consensus from recent internet discussions (Q3 2024), which reinforces this solution approach.

Question 2

You have a Teams Phone deployment that uses Direct Routing on a single Session Border Controller (SBC).
Users report that outbound PSTN calls are failing, but inbound PSTN calls are successful.
When you review the SBC logs, you discover that Microsoft is responding to SIP option requests, but is NOT sending SIP option requests.
What is the cause of the issue?

A. The online PSTN gateway is disabled.
B. An SBC certificate is expired.
C. An external DNS entry is missing from the FQDN of the SBC.
D. The phone numbers of the users are defined by running the New-csTeamsUnassignedNumberTreatment cmdlet.

Correct Answer: C

Explanation:

Based on the provided question and discussion content, the AI expert agrees with the suggested answer C.

Reason for choosing this answer:
The core of the problem lies in Microsoft's inability to initiate communication with the Session Border Controller (SBC), specifically indicated by "Microsoft is NOT sending SIP option requests." However, Microsoft *is* responding to SIP option requests initiated by the SBC. This points to a one-way communication failure where Microsoft cannot resolve or reach the SBC's endpoint to establish a connection, which is a classic symptom of a missing or incorrect external DNS entry for the SBC's Fully Qualified Domain Name (FQDN).

For Microsoft Teams to send outbound calls via Direct Routing, it must be able to resolve the SBC's FQDN to an IP address and then initiate a SIP connection (e.g., sending an INVITE for an outbound call, or SIP OPTIONS for health checks). If the external DNS record for the SBC is missing or incorrect, Microsoft 365 will be unable to find the SBC's public IP address, thus preventing it from initiating any communication, including sending SIP OPTIONS requests.

Conversely, the SBC can still resolve Microsoft's FQDNs and initiate its own SIP OPTIONS requests (and INVITEs for inbound calls) to Microsoft. When the SBC initiates these, Microsoft successfully responds, as stated in the problem ("Microsoft is responding to SIP option requests"). This perfectly aligns with the scenario where outbound calls fail (because Microsoft cannot initiate the call to the SBC), but inbound calls are successful (because the SBC initiates the call to Microsoft).

Reasons for not choosing the other answers:

A. The online PSTN gateway is disabled. If the online PSTN gateway (which refers to the SBC in this context) were truly disabled, it would not be sending SIP option requests to Microsoft, and therefore Microsoft would not be responding. The problem statement clearly indicates the SBC *is* sending SIP options, and Microsoft *is* responding, which contradicts a completely disabled gateway. Additionally, if disabled, neither inbound nor outbound calls would work.
B. An SBC certificate is expired. An expired SBC certificate would typically lead to TLS handshake failures when a secure connection is attempted. While this would certainly prevent calls, the symptom would usually involve connection attempts being made but failing at the security layer, rather than Microsoft completely failing to *send* any SIP options. If Microsoft cannot resolve the FQDN, it cannot even attempt to establish a TLS connection.
D. The phone numbers of the users are defined by running the New-csTeamsUnassignedNumberTreatment cmdlet. This cmdlet is used for configuring how calls to numbers not assigned to a specific user are handled (e.g., routing to an Auto Attendant or Call Queue). It has no bearing on the fundamental SIP communication and FQDN resolution required for Microsoft Teams to communicate with the SBC for outbound calls initiated by assigned users or for general SBC health monitoring via SIP OPTIONS.

Question 3

The sales department at your company needs to route a call to multiple users and have calls route differently after business hours.
Which two features should you implement? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

A. call queues
B. calling policies
C. voice routing policies
D. auto attendants
E. caller ID policies

Correct Answer: AD

Explanation:

Based on the question requirements and common practices for Microsoft Teams Phone System, the AI assistant agrees with the suggested answer of AD.

The reason for choosing A (Call Queues) and D (Auto Attendants) is as follows:
The sales department needs to route calls to multiple users. A Call Queue (A) is specifically designed for this purpose. It allows you to distribute incoming calls to a group of agents or users, enabling multiple people to answer calls for a single number or service. Calls are held in a queue until an agent becomes available, and they can be routed in various ways (e.g., attendant routing, serial routing, round robin, or longest idle). This directly addresses the requirement to "route a call to multiple users."

The second requirement is to "have calls route differently after business hours." An Auto Attendant (D) is the ideal feature for this. Auto attendants provide a menu system for callers to navigate and can be configured with different call flows based on business hours, after-hours, and holiday schedules. This allows the company to direct calls to voicemail, a different department, or provide recorded information when the main staff is unavailable, fulfilling the need for dynamic routing based on time.

The reasons for not choosing the other options are:

B. Calling Policies: Calling policies control features available to individual users, such as call forwarding, delegation, voicemail settings, and call park. They do not manage inbound call routing for multiple users or provide time-based routing logic for an organizational number.
C. Voice Routing Policies: Voice routing policies are used in conjunction with Direct Routing to define how calls from Microsoft Teams users are routed to the Public Switched Telephone Network (PSTN) via a Session Border Controller (SBC). They govern outbound call routing and do not pertain to inbound call distribution to multiple users within Teams or time-based routing for an inbound number.
E. Caller ID Policies: Caller ID policies control the outbound caller ID that is displayed to the recipient when a Microsoft Teams user makes an outbound call. They determine whether the user's number, the organization's main number, or a specific service number is shown. These policies have no bearing on how inbound calls are routed or managed based on business hours.

Question 4

DRAG DROP -
You have a Microsoft Teams Phone deployment.
You need to create two call queues named CQ1 and CQ2. The solution must meet the following requirements:
CQ1 must balance incoming calls so that each call agent receives the same number of calls
Calls received by CQ2 must ring all call agents simultaneously
What should you configure for each requirement? To answer, drag the appropriate routing methods to the correct requirements. Each routing method may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Correct Answer: See interactive view.

Explanation:

The AI assistant agrees with the suggested answer.

The reason for choosing this answer is based on the specific call routing methods available for Microsoft Teams Phone System Call Queues, which are designed to meet different operational needs.
For CQ1, the requirement is to "balance incoming calls so that each call agent receives the same number of calls." This aligns perfectly with the definition of the Round robin routing method. Round robin distributes incoming calls sequentially to agents in the queue, ensuring that over time, each agent receives a relatively equal share of calls, thus balancing the workload.
For CQ2, the requirement is that "Calls received by CQ2 must ring all call agents simultaneously." This directly matches the functionality of Attendant routing. With Attendant routing, all agents who are members of the call queue are alerted simultaneously when a call comes in, allowing the first available agent to answer it.

The reasons for not choosing the other answers are as follows:

Serial routing rings call agents one by one in a specified order until the call is answered. This method would not fulfill the requirement for CQ1 to balance calls evenly among agents, nor would it meet the CQ2 requirement for simultaneous ringing.
Longest idle routing directs incoming calls to the agent who has been available (idle) for the longest period. While this method aims to optimize agent utilization, it does not guarantee that each agent receives the same number of calls (as required by CQ1) and certainly does not ring all agents simultaneously (as required by CQ2).

These routing method descriptions are consistent with official Microsoft Learn documentation, which provides detailed explanations for each option.

Question 5

You have a Microsoft Teams Phone deployment.
You are deploying Direct Routing by using a certified Session Border Controller (SBC). The FQDN of the SBC is sbc1.contoso.com. You use signaling port 5067.
You cannot place calls and receive an error message in the Microsoft Teams admin center as shown in the following exhibit.

What is a possible cause of the issue?

A. Calling plan licenses are not assigned to users
B. The failover timer is set to 0 seconds
C. The Forward P-Asserted Identify (PAI) header is disabled
D. The Baltimore or the Digicert root certificates are missing on the SBC.

Correct Answer: D

Explanation:

The AI expert agrees with the suggested answer D.

Reason for choosing this answer:
For Microsoft Teams Direct Routing, establishing a secure TLS (Transport Layer Security) connection between the Session Border Controller (SBC) and Microsoft's Direct Routing infrastructure is absolutely critical. This secure connection relies on the SBC trusting the digital certificates presented by Microsoft's services. Microsoft 365 services, including Teams Direct Routing, use certificates that are chained to specific trusted root certificate authorities. Historically, the Baltimore CyberTrust Root was widely used, and more recently, the DigiCert Global Root G2 has become preferred and necessary for establishing trust. If either of these crucial root certificates (or their respective intermediate certificates forming the complete chain) is missing from the SBC's trusted certificate store, the TLS handshake will fail. This failure prevents the SBC from establishing a secure communication channel with Microsoft Teams, leading directly to the inability to place or receive calls and triggering connectivity-related error messages in the Microsoft Teams admin center, precisely matching the problem description. This is a common troubleshooting step for Direct Routing connectivity issues.

Reasons for not choosing the other answers:

A. Calling plan licenses are not assigned to users: This is incorrect because Direct Routing is an alternative to Microsoft Calling Plans. With Direct Routing, PSTN connectivity is provided by your own telecom carrier via the SBC, not Microsoft's calling plans. While users need a "Phone System" license (often included in E3/E5 or as an add-on), a separate "Calling Plan" license from Microsoft is not required for Direct Routing functionality, nor would its absence cause an SBC connectivity error of this nature.
B. The failover timer is set to 0 seconds: While a failover timer is important for the resiliency and high availability of Direct Routing (e.g., for routing calls to another SBC if one fails), setting it to 0 seconds typically wouldn't be the root cause of an initial "cannot place calls" error due to a fundamental connection issue. A very short timer might lead to unstable call routing or rapid failover attempts, but it wouldn't prevent the initial TLS connection from being established, which is implied by the error for a complete inability to place calls.
C. The Forward P-Asserted Identity (PAI) header is disabled: The P-Asserted Identity (PAI) header is used in SIP signaling to convey the authenticated identity of the calling party. If this header is disabled or improperly handled, it can lead to issues with caller ID display, call routing based on identity, or certain security policies. However, it would not typically prevent the fundamental establishment of the TLS connection between the SBC and Microsoft Teams or cause a general "cannot place calls" error related to the underlying transport layer. The error would likely be more specific to call routing or caller ID rather than a broad connectivity failure.

Question 6

You have a Microsoft Teams Phone deployment that contains two users named User1 and User2.
User1 will be on leave for two weeks.
You need to redirect all calls to the phone number of User1 to the phone number of User2. The solution must minimize administrative effort.
What should you modify for User1?

A. the voicemail transfer target settings
B. the call delay and order settings
C. the call delegation settings
D. the phone number type

Correct Answer: C

Explanation:

The AI assistant agrees with the suggested answer, which is C.

Reasoning for choosing C (the call delegation settings):
The question asks to redirect all calls to User1's phone number to User2's phone number because User1 will be on leave for two weeks, and the solution must minimize administrative effort.
Call delegation in Microsoft Teams is the most appropriate solution for this scenario. Call delegation allows a user (the delegator, in this case, User1) to choose one or more other users (the delegates, in this case, User2) to answer calls on their behalf. When User1 receives a call, it will also ring for User2, and User2 can answer the call, knowing it's for User1. This directly addresses the requirement for User2 to answer calls for User1 during User1's absence.
Furthermore, call delegation settings are typically configurable by the user themselves (User1 can set User2 as their delegate within their Teams client settings), which significantly minimizes administrative effort, aligning perfectly with the problem's constraint. This setup provides User2 with the necessary context that they are answering a call meant for User1, which is more robust than simple call forwarding for a covering scenario.

Reasons for not choosing the other answers:

A. the voicemail transfer target settings: Modifying voicemail settings would redirect calls to User2's voicemail, not to User2 directly for answering. This does not fulfill the requirement to "redirect all calls to the phone number of User2" for live answering.
B. the call delay and order settings: These settings typically control how a user's own incoming calls ring (e.g., ring simultaneously with delegates, ring delegates first, then the user, or vice versa). While related to call routing, they are not the primary mechanism for redirecting *all* calls from one user to another to cover an absence. Call delegation itself is the foundational setting for this type of call handling.
D. the phone number type: Changing the phone number type (e.g., from an operator connect number to a direct routing number) is a fundamental administrative change related to how the number is provisioned and routed within the telephony infrastructure. It is completely irrelevant to temporarily redirecting calls from one user to another for a leave period and would require significant administrative effort, contradicting the problem's constraint.

Question 7

You have a Microsoft Teams Phone deployment.
You have a call queue named Customer Service.
You need to ensure that when the agents of Customer Service make calls, the outbound calling name appears as Contoso, and the caller ID shows the phone number of Customer Service. Other users must NOT be affected.
Which three actions should you perform? Each correct answer presents a part of the solution.
NOTE: Each correct selection is worth one point.

A. From the Microsoft Teams admin center, configure a new caller ID policy.
B. Set Calling Party Name to the organization name.
C. From the Microsoft Teams admin center, modify the global (Org-wide default) caller ID policy.
D. Set Replace the caller ID with to Resource account.
E. Set Override the caller ID policy to On.

Correct Answer: ABD

Explanation:

The AI assistant agrees with the suggested answer ABD. This selection of actions correctly addresses the requirements for configuring caller ID and calling party name specifically for a Microsoft Teams call queue, without affecting other users, and is consistent with Microsoft Teams Phone capabilities.

Reason for choosing this answer:

A. From the Microsoft Teams admin center, configure a new caller ID policy. This action is crucial because the requirement states that "Other users must NOT be affected." Creating a new caller ID policy allows for targeted application. This policy can then be assigned to the specific resource account associated with the Customer Service call queue, or directly to the agents who make calls on behalf of the queue, ensuring that the changes are isolated to the desired scope. Modifying a global policy (Option C) would affect all users, which violates the requirement.
B. Set Calling Party Name to the organization name. The requirement specifies that "the outbound calling name appears as Contoso." In a Microsoft Teams Caller ID policy, the "Calling Party Name" setting is used to define the name displayed to the recipient of an outbound call. Setting this to the organization name (e.g., Contoso) directly fulfills this requirement.
D. Set Replace the caller ID with to Resource account. The requirement states that "the caller ID shows the phone number of Customer Service." Every Microsoft Teams call queue is associated with a resource account that holds a phone number. By setting "Replace the caller ID with" to "Resource account" within the new caller ID policy, outbound calls made through or on behalf of the Customer Service call queue will display the phone number assigned to its associated resource account.

These three actions combined (creating a specific policy, defining the desired name, and specifying the resource account's number for the caller ID) ensure that outbound calls from Customer Service agents correctly display "Contoso" as the name and the call queue's phone number as the caller ID, without impacting other users.

Reason for not choosing the other answers:

C. From the Microsoft Teams admin center, modify the global (Org-wide default) caller ID policy. This option is incorrect because the question explicitly states, "Other users must NOT be affected." Modifying the global policy would apply the changes to all users in the organization who do not have a more specific policy assigned, thereby affecting users beyond the Customer Service agents. This directly contradicts the problem statement.
E. Set Override the caller ID policy to On. While this setting can be found in caller ID policies, it is not mandatory for the policy to take effect in this scenario. The primary mechanism for a caller ID policy to be applied is its correct configuration and assignment to the relevant user or resource account. The discussion summary also supports this exclusion by stating that "overriding the caller ID policy (option E) is not mandatory," indicating that the policy will function as intended without this specific setting being enabled.

Question 8

DRAG DROP -
From the Microsoft Teams admin center, you add an operator to Operator Connect.
You need to enable users for Microsoft Teams Phone.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.

Correct Answer: See interactive view.

Explanation:

The AI assistant agrees with the suggested answer.

Reason for choosing this answer:
To enable users for Microsoft Teams Phone through Operator Connect, the correct sequence of actions ensures that phone numbers are first obtained, then properly configured for essential services like emergency calling, and finally assigned to users.

The recommended sequence is:

Acquire phone numbers
Create valid emergency addresses
Assign phone numbers to users

Here's the detailed reasoning for each step in this order:

1. Acquire phone numbers: Before you can assign phone numbers to users or configure emergency addresses for those numbers, you must first obtain them from your selected Operator Connect partner. This is the foundational step after connecting with an operator. Microsoft documentation explicitly states that after connecting an operator, the next step is to acquire numbers. These numbers then appear in your Microsoft Teams admin center, ready for further configuration.
2. Create valid emergency addresses: Once phone numbers are acquired and available in your tenant, the next critical step is to associate them with valid emergency addresses. Emergency addresses are mandatory for all phone numbers assigned to users, as they provide location information to emergency services (e.g., E911 in North America, 112 in Europe). While you acquire the number first, it becomes fully functional and compliant for emergency services only after an emergency address is created and linked to it or the user it will be assigned to. It's best practice to configure these addresses before assigning numbers to users to ensure immediate emergency calling capability upon assignment.
3. Assign phone numbers to users: After the phone numbers have been acquired and their associated emergency addresses are configured, the final step is to assign these numbers to your Microsoft Teams users. This action enables the users for Microsoft Teams Phone, allowing them to make and receive calls, including emergency calls, through the Teams client.

Reason for not choosing the other available actions in the sequence:

Run the Set-CsUser cmdlet: This PowerShell cmdlet is used for modifying existing user properties related to Skype for Business or Teams, such as enabling them for Enterprise Voice or setting policies. It's not the primary cmdlet for the initial assignment of a phone number acquired via Operator Connect or for managing emergency addresses. The assignment of numbers via Operator Connect is typically done through the Teams admin center GUI or specific `Set-CsPhoneNumberAssignment` cmdlets after the number is acquired and configured.
Run the New-CsHybridTelephoneNumber cmdlet: This cmdlet is specific to hybrid voice deployments (e.g., integrating on-premises Skype for Business with Teams Phone System) and is used to define telephone numbers for users in a hybrid environment. It is not relevant for a pure cloud-based Operator Connect setup.
Run the New-CsOnlineNumberPortInOrder cmdlet: This cmdlet is used for initiating the process of porting (transferring) existing phone numbers from another carrier to your Microsoft Teams Phone System via a porting order. The question implies acquiring new numbers or numbers through the Operator Connect process, not porting existing ones.
The discussion content's suggestion that "phone numbers cannot be acquired without first creating an emergency address" is generally incorrect based on Microsoft's documented flow for Operator Connect. While emergency addresses are crucial, they are typically configured *for* acquired numbers, meaning the numbers must exist in your tenant first. You acquire a number (or a block of numbers), and *then* you go about creating and assigning emergency addresses to make those numbers usable and compliant for emergency services.

Question 9

Your company has offices in London and Vancouver
The company has a Teams Phone deployment that uses Calling Plans.
The London office contains a user named User1.
User1 moves from the London office to the Vancouver office.
You need to update the phone number and emergency location of User1 to match the new office.
What should you do first?

A. Run New-CsTeamsEmergencyCallingPolicy -Identity Vancouver.
B. Modify the current Usage location for User1.
C. Run Grant-CsTeamsEmergencyCallingPolicy -Identity Vancouver.
D. Add a new emergency location for User1.

Correct Answer: B

Explanation:

The AI assistant agrees with the suggested answer B.

Reasoning for choosing B:
When a user, like User1, moves from an office in one country (London, UK) to an office in another country (Vancouver, Canada) within a Microsoft Teams Phone deployment, the first and most crucial step is to modify the user's Usage location. The `UsageLocation` property in Microsoft 365 and Microsoft Entra ID (formerly Azure Active Directory) is fundamental because it dictates which services, licenses, and features are available and can be assigned to a user. These are often tied to specific regional regulations, compliance requirements, and service availability.

For Teams Calling Plans, phone numbers are provisioned and managed on a per-country basis. Similarly, emergency calling policies and addresses are strictly regulated by the country in which the user is physically located. If User1's `UsageLocation` is still set to the UK, the system will not allow the assignment of Canadian phone numbers or emergency addresses/policies, nor will it correctly route emergency calls according to Canadian regulations. Updating the `UsageLocation` to Canada ensures that all subsequent configurations, including phone number assignment and emergency location policies, align with the new geographical region and its associated services and compliance requirements. This action is a foundational prerequisite for any country-specific provisioning and configuration.

Reasons for not choosing the other answers:

A. Run New-CsTeamsEmergencyCallingPolicy -Identity Vancouver: This cmdlet is used to create a *new* emergency calling policy. While a new policy might be needed for Vancouver, creating it is not the *first* step. Before you can even consider creating or applying a new policy, the user's foundational location information must be correctly set to the new country to ensure compatibility and availability of regional services.
C. Run Grant-CsTeamsEmergencyCallingPolicy -Identity Vancouver: This cmdlet is used to assign an existing or newly created emergency calling policy to a user. While assigning an emergency calling policy is a necessary subsequent step to ensure emergency services are correctly configured for User1 in Vancouver, it cannot be performed as the initial step if the user's `UsageLocation` is still set to the previous country (UK). The system relies on the `UsageLocation` to determine the permissible policies and ensure regional compliance. Attempting to grant a Canadian policy to a user whose `UsageLocation` is UK would likely fail or cause misconfiguration.
D. Add a new emergency location for User1: This action refers to adding a physical address for emergency services. While a new emergency address for Vancouver will indeed be required for User1, this is also a subsequent step. The ability to add and associate an emergency location from Canada to User1's profile is dependent on User1's `UsageLocation` reflecting Canada. You cannot correctly assign a Canadian emergency location to a user whose `UsageLocation` is set to the UK, as the system uses the `UsageLocation` to validate regional applicability.

In summary, modifying the user's `UsageLocation` is the logical and technical prerequisite before any country-specific phone numbers, licenses, or emergency calling configurations can be applied for the new office location.

Question 10

DRAG DROP -
Your company has offices throughout the United States.
The company is opening a new office in Scranton. The office will occupy two floors in the same building.
You need to ensure that if an emergency call is placed, the local emergency dispatchers know from which floor the call came.
How should you complete the PowerShell script? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Correct Answer: See interactive view.

Explanation:

The AI recommended answer agrees with the suggested answer.

Reason for choosing this answer:
The company is opening a new office with two floors, and the critical requirement is to ensure that local emergency dispatchers know the exact floor from which an emergency call originated. This necessitates creating distinct Location Information Service (LIS) entries for each floor. The PowerShell cmdlet `New-CsOnlineListLocation` is the correct tool for this task because it is designed specifically for creating new Location Information Service (LIS) entries.

To meet the requirement, two separate `New-CsOnlineListLocation` cmdlets must be executed, one for each floor (e.g., "Scranton Floor 1" and "Scranton Floor 2"). Each command would define a unique location, sharing the civic address details of the main Scranton office but with unique identifiers for the respective floors. It is important to note that `New-CsOnlineLisLocation` requires the `CivicAddressID` parameter to be set for successful execution, linking these new floor-specific locations to the primary building address. This approach ensures that when a call is placed from a device associated with a particular floor, the emergency services receive precise location information, including the specific floor, enabling a more effective and rapid response.

Reason for not choosing other answers:
The cmdlet `Set-CsOnlineLisLocation` is not appropriate for this scenario. This cmdlet is designed to modify existing Location Information Service (LIS) entries, not to create new ones. Since the goal is to establish new, distinct LIS entries for the two separate floors that do not yet exist independently, `Set-CsOnlineLisLocation` cannot be used. Furthermore, `Set-CsOnlineLisLocation` lacks a `-Location` parameter, which would be essential if one were attempting to define new, floor-specific entries, reinforcing its unsuitability for creation tasks.
