NCP-MCI-V6-5 Sample Questions

  1. Question 1

    Q1

    A financial services company is deploying a new mission-critical OLTP database on a Nutanix AHV cluster. The primary requirement is to achieve a Recovery Point Objective (RPO) of zero and a Recovery Time Objective (RTO) of less than 5 minutes in case of a site-wide outage. The company has two data centers with a high-speed, low-latency (<5ms RTT) dark fiber link. Which Nutanix data protection feature should the architect recommend to meet these stringent requirements?

    Show answer & explanation

    Correct answer: B

    Metro Availability is the only Nutanix feature that provides synchronous replication, which is required to achieve an RPO of zero. By creating a stretched storage container across two sites and configuring a Witness VM, it can automatically failover in the event of a site failure, meeting the low RTO requirement. NearSync offers a low RPO (down to 1 minute) but not zero. Asynchronous and snapshot-based protection do not meet the RPO requirement.

  2. Question 2

    Q2

    An administrator is managing a mixed-workload Nutanix cluster with both VDI and server VMs. To improve storage performance for the VDI workload, they decide to enable inline compression and deduplication on the VDI storage container. After a week, they observe that while storage capacity savings are significant, the performance of some write-intensive server VMs has slightly degraded. What is the most likely cause of this performance degradation?

    Show answer & explanation

    Correct answer: C

    Inline deduplication is a CPU-intensive process. The Controller VM (CVM) on each node is responsible for managing storage services, including deduplication fingerprinting and metadata management. Enabling this feature, especially on a heavily utilized cluster, can increase CVM CPU usage. Since the CVM's Stargate process handles I/O for all VMs on that host, this increased overhead can introduce latency that affects other workloads, even those not on the deduplicated container.

  3. Question 3

    Q3Multiple answers

    A Nutanix administrator is tasked with implementing microsegmentation for a three-tier application using Flow Network Security. The goal is to ensure the web servers can only communicate with the application servers, and the application servers can only communicate with the database servers. Which of the following components must be configured to achieve this isolation? (Select THREE)

    Show answer & explanation

    Correct answers: A, C, D

  4. Question 4

    Q4

    During a Life Cycle Manager (LCM) upgrade of the BIOS firmware on a cluster, one node fails the update process and is rolled back, while the others succeed. The administrator investigates and finds that the failed node's CVM is currently on a different host. Which AHV feature is most likely responsible for this situation and preventing the firmware upgrade?

    Show answer & explanation

    Correct answer: A

    CVM Autopathing is a high availability feature where a CVM can be live migrated to another host if its local host experiences a network failure, while its storage remains on the original host. LCM requires the CVM to be local to the host it is upgrading. The presence of the CVM on a different host indicates an Autopathing event has occurred, which must be resolved before the firmware upgrade can be successfully retried.

  5. Question 5

    Q5

    True or False: When creating a Volume Group on a Nutanix cluster to provide iSCSI storage, you must manually install and configure Nutanix Guest Tools (NGT) on the external client machine to enable the iSCSI initiator.

    Show answer & explanation

    Correct answer: B

    Nutanix Guest Tools (NGT) are installed inside virtual machines running on the Nutanix cluster to enhance management and integration. External clients connecting to a Volume Group via iSCSI are not VMs on the cluster and use their native operating system's iSCSI initiator. NGT is not applicable or required for these external clients.

  6. Question 6

    Q6

    An administrator needs to provide shared storage for a new containerized application environment running outside the Nutanix cluster. The application requires a POSIX-compliant, scale-out file system. Which Nutanix service should be deployed and configured to meet this requirement?

    Show answer & explanation

    Correct answer: C

    Nutanix Files is a software-defined, scale-out file storage solution that provides SMB and NFS shares. Since NFS is a POSIX-compliant protocol, Nutanix Files is the appropriate service to meet the requirements for the containerized application environment. Nutanix Volumes provides block storage (iSCSI), and Nutanix Objects provides S3-compatible object storage.

  7. Question 7

    Q7

    A hospital is using a Nutanix cluster to host its Electronic Health Record (EHR) system. They need to create a disaster recovery plan to a secondary site. The compliance requirements mandate that in the event of a disaster, the EHR system must be recoverable with no more than 15 minutes of data loss. Which replication schedule type should be configured on the Protection Domain?

    Show answer & explanation

    Correct answer: B

    The requirement is a maximum of 15 minutes of data loss, which translates to a Recovery Point Objective (RPO) of 15 minutes. Asynchronous replication allows for scheduled snapshots and replication. Configuring the schedule with an RPO of 15 minutes or less (e.g., every 15 minutes) will meet the compliance requirement. NearSync could also work but may be overkill, and Metro Availability is for RPO 0.

  8. Question 8

    Q8

    An administrator is attempting to add a new node to an existing AHV cluster. The process fails during the node discovery phase. The administrator confirms that the new node is on the same subnet as the existing CVMs and has the same hypervisor version. What is a common cause for this discovery failure?

    graph TD Admin[Admin] -->|`foundation-cli discover-nodes`| Foundation Foundation -->|Multicast Discovery| NewNode[New Node] NewNode --x|No Response| Foundation
    Show answer & explanation

    Correct answer: B

    Nutanix node discovery for cluster expansion relies on multicast traffic (specifically IPv6 multicast). Network switches with IGMP Snooping enabled can interfere with this process if not configured correctly with an IGMP querier, as they may block the multicast packets required for discovery. This is a very common cause of node discovery failures.

  9. Question 9

    Q9

    A new administrator takes over a Nutanix environment managed by Prism Central. They find that some VMs can be migrated between clusters, while others cannot. The administrator confirms that all clusters are running compatible AHV and AOS versions. What Prism Central construct is used to define which VMs are eligible for cross-cluster migration?

    Show answer & explanation

    Correct answer: B

    Categories are labels (key-value pairs) used in Prism Central to group entities like VMs. Policies, including migration and protection policies, are applied based on these categories. A VM must be in a specific category that is included in a protection policy or recovery plan to be eligible for migration or failover between clusters.

  10. Question 10

    Q10

    An administrator is reviewing the capacity runway for a cluster in Prism Central and notices that the storage runway is predicted to be exhausted in 30 days. The cluster currently has RF2 configured. The administrator has identified several non-critical, archive-level workloads that could tolerate a single component failure but not two simultaneous failures. Which action would be most effective in reclaiming storage capacity and extending the runway without purchasing new hardware?

    Show answer & explanation

    Correct answer: B

    Erasure Coding (EC-X) provides data protection by striping data and parity across nodes, which is more space-efficient than replication factor (RF2/RF3). For archive workloads where write performance is not critical, EC-X is an ideal way to reclaim significant storage capacity while maintaining data resilience against a single component failure. Creating a dedicated container and migrating the archive VMs allows for targeted application of this space-saving feature.
