Free [Nutanix] NCP-MCI (v6.5 & v10) - Nutanix NCP Multicloud Infra Practice Questions Preview

• Question 1

  After logging into Prism Element, an administrator presses the letter A on the keyboard.
  What is the expected outcome of this input?

  • A. Analysis page will launch.
  • B. Alerts page will launch.
  • C. About Nutanix page will launch.
  • D. API Explorer page will launch.

  Correct Answer: B

  Explanation:

  The AI agrees with the suggested answer B. Alerts page will launch.
  Reasoning: According to community discussions and practical experience, pressing the "A" key in Prism Element directly opens the Alerts page. This is a known shortcut within the Prism Element interface.
  Reasons for not choosing other answers:

  • A: Analysis page will launch. - This is incorrect as pressing "A" directly navigates to the Alerts page, not the Analysis page.
  • C: About Nutanix page will launch. - This is incorrect; there's no default keyboard shortcut "A" to open the "About Nutanix" page.
  • D: API Explorer page will launch. - This is incorrect because pressing "A" is specifically linked to Alerts in Prism Element.

  In summary, the "A" key is a shortcut specifically for the Alerts page within the Prism Element interface.

• Question 2

  Refer to the exhibit.
  
  The Update Source for LCM has been configured as shown in the exhibit. Inventory is failing consistently.
  What is the likely cause of this issue?

  • A. Port 80 is blocked by a firewall.
  • B. The administrator does not have a valid portal account.
  • C. The license assigned to the cluster has expired.
  • D. Port 443 is blocked by a firewall.

  Correct Answer: D

  Explanation:

  The AI assistant agrees with the suggested answer (D).
  Reasoning: The exhibit shows that "Enable HTTPS" is checked. When HTTPS is enabled, the LCM process communicates with the Nutanix portal over port 443. If this port is blocked by a firewall, the inventory process will fail.
  Why other options are incorrect:

  • A. Port 80 is used for HTTP, but since HTTPS is enabled, port 443 is more likely to be the issue.
  • B. A valid portal account is needed for downloading metadata, but a firewall blocking port 443 would prevent any communication in the first place.
  • C. An expired license might prevent certain features from working, but it's less likely to directly cause an inventory failure if the communication port is blocked.

  Therefore, the most likely cause of the issue is that port 443 is blocked by a firewall.

• Question 3

  An administrator has created a Nutanix managed network, and assigned it a VLAN ID of 512.
  Several VMs have been created, and the administrator notices that the VMs can successfully communicate with other VMs on that VLAN, provided they are on the same host, but cannot communicate with VMs that reside on different hosts in the cluster.
  What is most likely the cause of this issue?

  • A. There is a firewall rule blocking VLAN512 traffic.
  • B. The VLAN was not created on the upstream switches.
  • C. The administrator did not create the VLAN on all hosts.
  • D. VLAN512 is a reserved VLAN ID, and not usable for guest VMs.

  Correct Answer: B

  Explanation:

  The AI agrees with the suggested answer B.
  The most likely cause is that the VLAN was not created on the upstream switches.
  This is because when VMs on the same host can communicate on VLAN 512, but VMs on different hosts cannot, it indicates that the VLAN is not properly configured on the physical network to allow inter-host communication. Nutanix relies on the upstream switches to route traffic between hosts for a given VLAN. If the VLAN is not defined on the upstream switches, the traffic will not be routed correctly.
  

  Here's a breakdown of why the other options are less likely:

  • A. There is a firewall rule blocking VLAN512 traffic: While a firewall rule could block traffic, it's less likely if VMs on the same host can communicate. Firewall rules typically apply cluster-wide, so blocking inter-host traffic would likely also block intra-host traffic.
  • C. The administrator did not create the VLAN on all hosts: With Nutanix managed network, VLAN creation is typically handled centrally, and doesn't require manual VLAN creation on each host. So this is less likely.
  • D. VLAN512 is a reserved VLAN ID, and not usable for guest VMs: 512 is not a reserved VLAN ID. VLAN IDs 1-4094 are usable, though some might be reserved for specific purposes in certain environments.

  Therefore, the absence of the VLAN configuration on the upstream switches is the most probable cause of the described issue.

• Question 4

  An administrator logs into the Nutanix Support Portal and notices there is a new version of the LCM Framework available. In an effort to ensure LCM is providing the latest features, the administrator would like to upgrade LCM.
  How can the LCM Framework be upgraded?

  • A. Upload the latest LCM Framework bundle via Upgrade Software in Prism
  • B. Upload the latest LCM Framework as an image in the Image Configuration in Prism
  • C. Upgrade AOS
  • D. Perform an LCM inventory

  Correct Answer: D

  Explanation:

  The AI concurs with the suggested answer. The correct answer is D: Perform an LCM inventory.
  
  Reasoning: LCM (Life Cycle Manager) updates its framework through the inventory process. When an inventory is performed, LCM checks for updates to its own components and applies them if available. This ensures that the LCM framework is running the latest version.
  
  Why other options are incorrect:

  • A: Uploading the LCM Framework bundle via Upgrade Software in Prism is not the correct method for upgrading the LCM Framework. This method is used for upgrading other software components within the Nutanix environment, such as AOS or hypervisor.
  • B: Uploading the LCM Framework as an image in the Image Configuration in Prism is not the correct procedure. The Image Configuration section is used to manage bootable images for VMs, not for upgrading LCM.
  • C: Upgrading AOS will update certain LCM components, but it will not ensure the LCM framework is running the absolute latest version. An LCM inventory is still required.

  Nutanix documentation confirms that LCM automatically updates its own framework during an inventory process.

• Question 5

  On a Nutanix cluster, what does Network Segmentation refer to?

  • A. Isolating management traffic from storage replication traffic.
  • B. Physically separating management traffic from guest VM traffic.
  • C. Isolating intra-cluster traffic from guest VM traffic.
  • D. A distributed firewall for securing VM to VM traffic.

  Correct Answer: A

  Explanation:

  The AI agrees with the suggested answer of A.
  Reasoning: Network Segmentation on a Nutanix cluster primarily refers to isolating different types of traffic for security and performance reasons. Isolating management traffic from storage replication traffic is a key aspect of this segmentation. This can be achieved through VLANs or other network separation techniques, ensuring that storage replication processes do not interfere with the management plane's operations and vice versa. This separation enhances security and maintains predictable performance for both management and storage functions.
  Reasons for not choosing the other answers:

  • B: Physically separating management traffic from guest VM traffic, while a valid security practice in general networking, is not the primary definition of network segmentation within the context of Nutanix clusters. Nutanix can handle VM traffic and management traffic separation through other mechanisms.
  • C: Isolating intra-cluster traffic from guest VM traffic is again a valid network practice, it is not the primary focus of network segmentation within a Nutanix cluster context.
  • D: A distributed firewall for securing VM to VM traffic represents microsegmentation or application-centric security, which is a related but distinct concept from basic network segmentation. While Nutanix does offer microsegmentation capabilities, the fundamental concept of network segmentation, in this case, refers more to isolating specific types of cluster traffic.

• Question 6

  Which component can be associated with a storage policy?

  • A. Catalog
  • B. VM
  • C. Category
  • D. Subnet

  Correct Answer: B

  Explanation:

  The AI suggests that the correct answer is C. Category.
  
  Reasoning:
  Based on the discussion summary, a storage policy is associated with a category, which in turn is associated with VMs. This means VMs don't directly have storage policies assigned. The category acts as an intermediary, allowing you to apply a specific storage policy to all VMs within that category.
  
  Reasons for not choosing other answers:
  

  • A. Catalog: Catalogs are typically used for organizing and managing VM templates, ISO images, and other resources, not directly associated with storage policies.
  • B. VM: While VMs are affected by storage policies, the policy is not directly attached to them. It's applied through the category.
  • D. Subnet: Subnets are related to network configuration and IP addressing, and are not related to storage policies.

• Question 7

  Refer to the exhibit.
  
  An administrator needs to update some images that were previously uploaded to their Nutanix cluster. While logged into Prism Element when trying to update the images, the update icon is not enabled.
  What could be the cause for this behavior?

  • A. The files were ISO but were uploaded as disk images hence cannot be used or edited.
  • B. Images are corrupted and must be re-uploaded.
  • C. RBAC is configured and the administrator's user doesn't have the right privileges.
  • D. Images were imported into Prism Central.

  Correct Answer: D

  Explanation:

  The AI agrees with the suggested answer D.
  Reasoning: If images are managed through Prism Central, any updates to these images must be done through Prism Central. When images are imported into Prism Central, Prism Central stores the image metadata and manages updates, while the actual image file remains on the original cluster. Thus, the update function is disabled in Prism Element.
  Reasons for not choosing other options:

  • A: The file type being ISO or disk image doesn't directly impact the update icon being disabled. While incorrect file types can cause issues, the scenario specifically points to the update icon being disabled, suggesting a management issue rather than a file type issue.
  • B: Image corruption would likely result in errors during usage, not a disabled update icon. Also, the question specified the icon is disabled.
  • C: While RBAC can restrict access, it's less likely to be the primary cause if the administrator can view the images but cannot update them. RBAC issues usually manifest as inability to view or access resources at all.

• Question 8

  Refer to the exhibit.
  
  Why has an anomaly been triggered?

  • A. Because the CPU usage reached 100%.
  • B. Because the CPU usage crossed the blue band.
  • C. Because the CPU usage dropped below 20%.
  • D. Because the blue band range increased over the last 2 days.

  Correct Answer: B

  Explanation:

  The AI agrees with the suggested answer, B.
  The reason for this choice is based on the description that an anomaly is triggered when the CPU usage crosses the blue band, which represents the expected range of CPU usage. The anomaly detection module compares observed usage with predicted values, and a flag is raised if the observed value falls outside this band.
  The other options are incorrect because:
  

  • A: While 100% CPU usage *could* trigger an anomaly, the key indicator from the graph and the description is crossing the blue band. The graph doesn't definitively show 100% usage, just high usage.
  • C: A drop below 20% CPU usage *might* trigger an anomaly depending on the expected baseline, but the primary indicator for anomaly detection described is deviation from the blue band.
  • D: The graph provides insufficient data to determine whether the band range itself has increased. Moreover, the definition states anomaly detection happens when the usage goes beyond the band.

• Question 9

  An administrator wants to expand the Failure Domain level of a cluster.
  What two options are available? (Choose two.)

  • A. Data Center
  • B. Node
  • C. Block
  • D. Rack

  Correct Answer: CD

  Explanation:

  The AI agrees with the suggested answer of C and D.
  
  Reasoning:
  The question asks about expanding the Failure Domain level of a cluster. Failure domains, also sometimes referred to as fault tolerance levels, determine how resilient the cluster is to failures. Nutanix allows administrators to configure fault tolerance at different levels. According to Nutanix documentation, the configurable options for failure domains are Block and Rack. Increasing the failure domain to include Blocks and Racks provides greater resilience against hardware failures.
  
  Why other options are incorrect:

  • A. Data Center: While a data center outage is a significant failure scenario, Nutanix doesn't directly manage data center-level failure domains as a configurable option within the cluster itself. Disaster recovery solutions are used for data center level protection
  • B. Node: Node-level failure tolerance is inherent in the Nutanix architecture (through replication factor). While node failures are handled, administrators don't "expand" the failure domain *to* the node level since it's already a base level of fault tolerance.

  In summary, the only configurable options to expand failure domains within a Nutanix cluster are Block and Rack.

• Question 10

  An administrator is tasked with configuring networking on an AHV cluster and needs to optimize for maximum single VM throughput.
  Which bond mode should the administrator select?

  • A. Active-Active
  • B. Active-Active with Mac Pinning
  • C. Active-Backup
  • D. No Uplink Bond

  Correct Answer: A

  Explanation:

  The AI agrees with the suggested answer, which is A (Active-Active).
  Reasoning: The question aims to identify the optimal bond mode for maximum single VM throughput in an AHV cluster. Active-Active bond mode is designed to utilize all available uplinks simultaneously, thus providing the highest possible throughput for a single VM by distributing traffic across multiple physical links.
  Reasons for not choosing the other options:

  • Active-Active with Mac Pinning (B): While this option does use multiple uplinks, MAC pinning can limit the distribution of a single VM's traffic, potentially reducing maximum throughput compared to a standard Active-Active configuration.
  • Active-Backup (C): This mode only uses one uplink at a time, with the backup link becoming active only if the primary fails. It doesn't provide the aggregated bandwidth benefit of Active-Active.
  • No Uplink Bond (D): Using no uplink bond would result in a single point of failure and severely limit the available bandwidth to the VM.
