• Question 1

  Which two functionalities does Cisco Expressway provide in the Cisco Collaboration architecture? (Choose two.)
  

  • A. Survivable Remote Site Telephony functionality
  • B. MGCP gateway registration
  • C. secure business-to-business communications
  • D. customer interaction management services
  • E. secure firewall traversal for remote devices

  Correct Answer: CE

  Explanation:

  The suggested answer is CE. After analyzing the question and available resources, the AI confirms that options C and E are indeed the most accurate functionalities provided by Cisco Expressway within a Cisco Collaboration architecture.
  
  Reasoning:

  • Cisco Expressway facilitates secure business-to-business (B2B) communications. It enables secure and reliable connections between different organizations' collaboration networks, allowing them to share voice, video, and data. This functionality is crucial for organizations that need to collaborate with partners, suppliers, and customers outside of their own network.
  • Cisco Expressway provides secure firewall traversal for remote devices. It allows users to securely connect to the corporate network from outside the firewall without requiring a VPN. This is achieved through its Mobile and Remote Access (MRA) feature, which enables devices to register and communicate securely with the Cisco Unified Communications Manager (CUCM) and other collaboration applications.

  Why other options are incorrect:

  • A. Survivable Remote Site Telephony (SRST) functionality: SRST is primarily a feature of Cisco Unified Communications Manager (CUCM) and certain routers, not Cisco Expressway. SRST provides basic call-handling capabilities at a remote site when the connection to the central CUCM is lost.
  • B. MGCP gateway registration: MGCP (Media Gateway Control Protocol) is an older protocol used for controlling media gateways. While Expressway can work with gateways, it doesn't directly handle MGCP gateway registration in the same way as CUCM. The trend is towards SIP-based communication.
  • D. Customer interaction management services: Customer interaction management services are typically provided by dedicated contact center platforms like Cisco Unified Contact Center Enterprise (UCCE) or Cisco Unified Contact Center Express (UCCX), not by Cisco Expressway.

• Question 2

  An engineer must extend the corporate phone system to mobile users connecting through the internet with their own devices. One requirement is to keep that as simple as possible for end users. Which infrastructure element achieves these goals?
  

  • A. Cisco Express Mobility
  • B. Cisco Expressway-C and Expressway-E
  • C. Cisco Unified Border Element
  • D. Cisco Unified Instant Messaging and Presence

  Correct Answer: B

  Explanation:

  The AI agrees with the suggested answer.
  The recommended answer is B: Cisco Expressway-C and Expressway-E.
  
  Reasoning:
  Expressway indeed provides a secure and simplified solution for extending corporate phone systems to mobile users connecting via the internet with their own devices. The Expressway-C (Core) and Expressway-E (Edge) pair handle secure traversal of NAT and firewalls, enabling mobile users to connect to the internal Cisco Unified Communications Manager (CUCM) deployment without a VPN. This solution is designed for simplicity for the end-user.
  
  Reasons for not choosing the other options:

  • A: Cisco Express Mobility: While related to mobility, this isn't the core infrastructure element facilitating secure internet-based connections for mobile users with their own devices.
  • C: Cisco Unified Border Element (CUBE): CUBE primarily handles SIP trunking and connectivity between an enterprise network and a service provider network. It is not directly involved in providing mobile users with access to internal communication systems over the internet.
  • D: Cisco Unified Instant Messaging and Presence: This component manages instant messaging and presence information, not voice or video communication and secure traversal.

• Question 3

  A customer wants a video conference with five Cisco TelePresence IX5000 Series systems. Which media resource is necessary in the design to fully utilize the immersive functions?
  

  • A. Cisco PVDM4-128
  • B. software conference bridge on Cisco Unified Communications Manager
  • C. Cisco Webex Meetings Server
  • D. Cisco Meeting Server

  Correct Answer: D

  Explanation:

  The suggested answer is D: Cisco Meeting Server.
  
  The AI agrees with the suggested answer, Cisco Meeting Server (CMS) is the correct choice because it provides the necessary media resources to fully utilize the immersive features of a video conference with five Cisco TelePresence IX5000 Series systems. CMS is designed to handle the high bandwidth and processing requirements of such conferences, enabling features like continuous presence and spatial audio.
  
  Here's why the other options are not the best fit:

  • A. Cisco PVDM4-128: PVDMs (Packet Voice Digital Signal Processors) are primarily used for voice processing functions like transcoding and conferencing in Cisco routers and voice gateways. They are not designed to handle the video processing demands of a TelePresence conference.
  • B. Software conference bridge on Cisco Unified Communications Manager: While CUCM can handle audio and video conferencing, it is not optimized for the immersive experience provided by TelePresence systems, especially when involving multiple IX5000 systems. It may lack the necessary capacity and features for a seamless experience.
  • C. Cisco Webex Meetings Server: While Webex is a conferencing solution, the on-premises Webex Meetings Server is outdated and End of Life since October 31, 2023.
    

  Therefore, Cisco Meeting Server is the most suitable option for providing the necessary media resources to support the immersive functions of a video conference involving multiple Cisco TelePresence IX5000 Series systems.

• Question 4

  An engineer is designing a load balancing solution for two Cisco Unified Border Element routers. The first router (cube1.abׁ.com) takes 60% of the calls and the second router (cube2.abc.com) takes 40% of the calls. Assume all DNS A records have been created. Which two SRV records are needed for a load balanced solution? (Choose two.)
  

  • A. _sip._udp.abc.com 60 IN SRV 2 60 5060 cube1.abc.com
  • B. _sip._udp.abc.com 60 IN SRV 60 1 5060 cube1.abc.com
  • C. _sip._udp.abc.com 60 IN SRV 1 40 5060 cube2.abc.com
  • D. _sip._udp.abc.com 60 IN SRV 3 60 5060 cube2.abc.com
  • E. _sip._udp.abc.com 60 IN SRV 1 60 5060 cube1.abc.com

  Correct Answer: CE

  Explanation:

  The AI recommends options C and E as the correct answers.
  
  Reasoning:
  The correct SRV records should reflect the load balancing requirements specified in the question (60% to cube1.abc.com and 40% to cube2.abc.com). SRV records utilize priority and weight to distribute the load. Lower priority values are preferred, and weight is used to distribute load among records with the same priority.
  
  Option E: `_sip._udp.abc.com 60 IN SRV 1 60 5060 cube1.abc.com`
  - This record assigns a priority of 1 and a weight of 60 to cube1.abc.com. Given the requirement of 60% of the calls being routed to cube1.abc.com, a higher weight is appropriate for this server.
  
  Option C: `_sip._udp.abc.com 60 IN SRV 1 40 5060 cube2.abc.com`
  - This record assigns a priority of 1 and a weight of 40 to cube2.abc.com. With 40% of the calls destined for cube2.abc.com, this configuration aligns with the problem description.
  
  By assigning the same priority (1) to both CUBE routers and using weights of 60 and 40 respectively, we achieve the desired 60/40 load balancing.
  
  Why other options are incorrect:
  Option A: `_sip._udp.abc.com 60 IN SRV 2 60 5060 cube1.abc.com`
  - Has a priority of 2, making it a backup if the record with priority 1 isn't available. It won't participate in load balancing.
  
  Option B: `_sip._udp.abc.com 60 IN SRV 60 1 5060 cube1.abc.com`
  - This record uses priority 60 and weight 1, which doesn't reflect any intention for load balancing, and the high priority value will make it the least preferred record.
  
  Option D: `_sip._udp.abc.com 60 IN SRV 3 60 5060 cube2.abc.com`
  - It also has a higher priority than option E and C, therefore it will not participate in load balancing.

• Question 5

  Which two functions are provided by Cisco Expressway Series? (Choose two.)
  

  • A. interworking of SIP and H.323
  • B. endpoint registration
  • C. intercluster extension mobility
  • D. voice and video transcoding
  • E. voice and video conferencing

  Correct Answer: AB

  Explanation:

  The AI agrees with the suggested answer. The Cisco Expressway Series provides several key functions, including interworking of SIP and H.323 and endpoint registration.
  
  Suggested answer: A and B.
  
  Reasoning for choosing A and B:
  

  • **A. Interworking of SIP and H.323:** Cisco Expressway is designed to provide interoperability between different signaling protocols, including SIP and H.323. This is a core function of the Expressway, allowing devices using different protocols to communicate with each other.
  • **B. Endpoint registration:** Cisco Expressway can act as a registration point for endpoints, allowing them to register and be managed within the network. This is particularly important for mobile and remote access scenarios.

  Reasoning for not choosing the other answers:
  

  • **C. Intercluster extension mobility:** While Cisco Unified Communications Manager (CUCM) provides intercluster extension mobility, this is not a primary function of the Cisco Expressway. Expressway focuses on providing secure communication and interoperability between different networks and protocols.
  • **D. Voice and video transcoding:** Although Expressway can perform some media handling functions, dedicated transcoding is not a primary function. Cisco MediaSense or specialized transcoding servers are typically used for heavy transcoding needs.
  • **E. Voice and video conferencing:** While Expressway facilitates connectivity for conferencing, it doesn't provide actual conferencing capabilities. Cisco Meeting Server or CUCM with conferencing bridges handles that.

• Question 6

  An incoming off-net call to a user fails. An engineer notices that the off-net call is G.711, but the phone accepts only G.729. Which media resource on a Cisco
  Unified Border Element and Cisco Unified Communications Manager must the engineer configure to manage the codec negotiation?
  

  • A. transcoder
  • B. CFB
  • C. MOH
  • D. MTP

  Correct Answer: A

  Explanation:

  The suggested answer is A, transcoder.
  The AI agrees with the suggested answer.
  Reasoning: A transcoder is the correct media resource to configure on a Cisco Unified Border Element (CUBE) and Cisco Unified Communications Manager (CUCM) to manage codec negotiation when an incoming off-net call uses G.711 codec, and the phone only accepts G.729. A transcoder converts the audio stream from one codec (G.711) to another (G.729), enabling the call to proceed successfully.
  Reasons for not choosing other options:
  

  • B. CFB (Call Forward Busy): Call Forward Busy is a feature that redirects calls when the called party's line is busy. It doesn't handle codec negotiation.
  • C. MOH (Music on Hold): Music on Hold provides music or a recorded message to callers while they are on hold. It is unrelated to codec negotiation.
  • D. MTP (Media Termination Point): While MTPs can handle certain media processing tasks, they primarily deal with DTMF relay and other signaling functions. They are not designed for real-time codec conversion between G.711 and G.729 in this scenario. According to Cisco documentation, MTPs are not capable of transcoding.

• Question 7

  Which Cisco Unified Communications Manager service parameter should be enabled disconnect a multiparty call when the call initiator hangs up?
  

  • A. Drop Ad Hoc Conference
  • B. H.225 Block Setup Destination
  • C. Block OffNet To OffNet Transfer
  • D. Enterprise Feature Access Code for Conference

  Correct Answer: A

  Explanation:

  The suggested answer is A, Drop Ad Hoc Conference.
  
  The AI agrees with the suggested answer.
  
  Reasoning:
  The "Drop Ad Hoc Conference" service parameter in Cisco Unified Communications Manager (CUCM) is designed to disconnect a multiparty call (specifically an ad-hoc conference) when the call initiator hangs up. This parameter directly addresses the scenario described in the question.
  
  From Cisco documentation, this parameter controls whether an ad hoc conference call is dropped when the conference initiator disconnects. Setting it to "True" ensures that the conference ends when the initiator leaves, which is a common requirement for managing conference call resources and preventing unintended continued usage.
  
  Reasons for not choosing other options:
  

  • B. H.225 Block Setup Destination: This parameter relates to call routing and blocking calls based on destination patterns using the H.225 protocol, not directly to conference call behavior or initiator hang-up scenarios.
  • C. Block OffNet To OffNet Transfer: This parameter prevents calls from being transferred between off-net (external) numbers, which is a security feature but unrelated to conference call control.
  • D. Enterprise Feature Access Code for Conference: This defines the code used to initiate a conference call, not how the call behaves when the initiator disconnects.

• Question 8

  A network administrator deleted a user from the LDAP directory of a company. The end user shows as Inactive LDAP Synchronized User in Cisco Unified
  Communications Manager. Which step is next to remove this user from Cisco Unified Communications Manager?
  

  • A. Delete the user directly from Cisco Unified Communications Manager
  • B. Restart the Dirsync service after the user is deleted from LDAP directory.
  • C. Execute a manual sync to refresh the local database and delete the end user.
  • D. Wait 24 hours for the garbage collector to remove the user.

  Correct Answer: D

  Explanation:

  The AI recommends answer D.
  The suggested answer (D) is correct.
  Reasoning: The question describes a scenario where a user has been deleted from the LDAP directory and is now showing as an "Inactive LDAP Synchronized User" in Cisco Unified Communications Manager (CUCM). The final step to remove this user completely from CUCM is indeed to wait for the garbage collection process to run. According to Cisco documentation and community discussions, the garbage collector automatically removes inactive users after a certain period, which is typically 24 hours. This automated process ensures that the CUCM database remains clean and synchronized with the LDAP directory.
  Reasons for not choosing other answers:
  

  • A: Deleting the user directly from CUCM is not the correct approach after LDAP synchronization. The user is already marked as inactive due to the LDAP deletion, and directly deleting might cause inconsistencies.
  • B: Restarting the Dirsync service might trigger a synchronization, but it won't force the immediate removal of the inactive user. The garbage collector is the specific process designed for this purpose.
  • C: Executing a manual sync can refresh the database, but it will likely only update the user's status to inactive rather than removing them entirely. The garbage collector is still required for the final removal.

• Question 9

  A customer has Cisco Unity Connections that is integrated with LDAP. As a Unity Connection administrator, you have received a request to change the first name for VM user. Where must the change be performed?
  

  • A. Cisco Unity Connection
  • B. Cisco Unified Communications Manager end user
  • C. Active Directory
  • D. Cisco IM and Presence

  Correct Answer: C

  Explanation:

  The suggested answer is C, Active Directory.
  The AI agrees with the suggested answer, C (Active Directory).
  Reasoning: When Cisco Unity Connection is integrated with LDAP (Lightweight Directory Access Protocol), it synchronizes user information from the LDAP directory service. In most enterprise environments, this LDAP directory service is Active Directory. Therefore, to change a user's first name, the modification must be made in Active Directory, which will then be synchronized with Cisco Unity Connection during the next synchronization cycle. Cisco Unity Connection itself does not hold the authoritative source of user information in an LDAP-integrated environment; it merely reflects the data stored in the LDAP directory.
  Reasons for not choosing other options:
  

  • A. Cisco Unity Connection: If integrated with LDAP, Unity Connection is not the authoritative source for user data. Changes made directly in Unity Connection would be overwritten during the next synchronization with the LDAP directory.
  • B. Cisco Unified Communications Manager end user: While CUCM can integrate with LDAP for user authentication and information, Unity Connection, when integrated with LDAP, primarily relies on the LDAP directory (typically Active Directory) for user data synchronization. Changes in CUCM's end user configuration would not directly impact Unity Connection's user information in an LDAP integrated environment. Additionally, the discussion highlights that CUCM uses AXL and not LDAP.
  • D. Cisco IM and Presence: Cisco IM and Presence handles presence information and instant messaging capabilities. It does not manage core user attributes like first name for Unity Connection, especially when Unity Connection is integrated with LDAP.

  In summary, the correct place to change the first name is Active Directory because Unity Connection synchronizes user information from the LDAP directory in this scenario.

• Question 10

  Which configuration step is necessary for a Cisco SIP phone to synchronize its time with a specific source?
  

  • A. Add a Phone NTP Reference to the Date/Time Group.
  • B. Assign the device to the correct region.
  • C. Change the Time Format from 24-hour to 12-hour.
  • D. Change the Time Zone from ג€America/Los_Angeles" to ג€Etc/GMT+8".

  Correct Answer: A

  Explanation:

  The AI concurs with the suggested answer. The correct answer is A: Add a Phone NTP Reference to the Date/Time Group.
  Reasoning: Cisco SIP phones rely on NTP (Network Time Protocol) to synchronize their time. To ensure a phone synchronizes with a specific NTP source, you must configure the Date/Time Group with a Phone NTP Reference. This configuration tells the phone where to obtain the correct time.
  Why other options are incorrect:

  • B. Assigning the device to the correct region is related to device mobility and call routing, not time synchronization.
  • C. Changing the Time Format (24-hour to 12-hour) only affects how the time is displayed, not the time source.
  • D. Changing the Time Zone might be necessary in some deployments to reflect the local time, but setting the time zone alone doesn't guarantee synchronization with a specific NTP source. The NTP source provides the accurate time, and the time zone adjusts the display accordingly.
