Nutanix Nutanix Certifications NCA-6.5 Questions & Answers

• Question 121:

  In an AHV five-node cluster, an SSD fails within a node that has two SSDs and four HDDs installed. What will happen to the cluster environment?

  A. Host goes down and VMs will be powered on elsewhere.

  B. Cluster goes in read-only mode.

  C. VMs will be live migrated to other hosts until metadata rebuild is finished.

  D. CVM on the impacted node reboots.

  Correct Answer: D

  When an SSD fails within a node, the CVM on that node will reboot to maintain the health of the cluster. The CVM is responsible for managing the storage and virtualization components of the cluster, and a reboot is necessary to ensure that the cluster continues to function properly. The VMs running on that host will not be affected and continue to run, but the CVM will be unavailable for a short period of time until the reboot is completed. The Cluster continues to operate in a healthy state and doesn't go in read-only mode or cause any host to go down.

• Question 122:

  On which entity is Replication Factor configured?

  A. Host

  B. Oplog

  C. Volume

  D. Container

  Correct Answer: D

  Replication Factor is configured on a Container entity. Containers group together virtual disks and files, and allow administrators to set policies on a group level. This allows for increased flexibility in managing storage resources and allows administrators to easily set policies across multiple virtual disks and files. Replication Factor is configured on Containers. A container is a logical grouping of one or more storage pools and defines the storage resources available to virtual machines. The replication factor is a setting that determines the number of copies of data that are stored across the cluster. By configuring the replication factor on a container, you are setting the number of copies of data that will be stored for all virtual machines that are associated with that container. For example, if you have a container with a replication factor of 3, it means that three copies of data will be stored across the cluster, and two copies are required to reconstruct the data in case of a failure.

• Question 130:

  An administrator is unable to discover a Nutanix-hosted iSCSI block device allocated to a bare-metal host. What is causing this issue?

  A. Jumbo frames has not been configured on the switch

  B. External client access has not been enabled for the host

  C. Network segmentation has not been enabled

  D. External host IP address is not in the Filesystem Whitelist

  Correct Answer: D

  Nutanix Volumes uses a Filesystem Whitelist to control which external hosts can access the iSCSI block devices allocated to them. If the external host IP address is not in the Filesystem Whitelist, it will not be able to discover or connect to the

  Nutanix-hosted iSCSI block device. Jumbo frames, external client access, and network segmentation are not required for Nutanix Volumes to work. References:
