NO.42 What requirement needs to be considered before configuring Replication Factor of 1 (RF1)?

Application resiliency

Hypervisor

RAID configuration

Node count

To configure Replication Factor 1 (RF1), the cluster must have at least three nodes. In RF1, data is replicated to two other nodes within the cluster, so having at least three nodes is necessary to ensure that the data is replicated. Moreover, when you configure RF1, the cluster must have a minimum of three nodes to ensure that the data is accessible even if one of the nodes goes down. Reference: https://portal.nutanix.com/page/documents/details?targetId=Prism-Admin-Guide-v5_6:pr-data-protection-replication-factor-c.html

NO.43 Refer to the exhibit.

An administrator notices that the Data Resiliency Statue of some components has been reduced to 0. making it impossible to support a node failure in the cluster.
What type of failure is most likely the cause of this issue?

Block

Disk

CVM

Nods

NO.44 Which account is recommended for performing tasks and operations on the CVM via SSH?

administrator

admin

nutanix

root

NO.45 An administrator receives an alert that a node has failed within a Nutanix AHV-based 10-node cluster. Before the failure, the cluster CPU and memory utilization was around 50%.
What actions will the cluster automatically take?

VMs will be unavailable until the affected host is fully functional.

VMs will migrate to other nodes in the cluster with no user impact.

The cluster will enter read-only mode and the VMs will be powered down to preserve data.

All HA-protected VMs will be automatically restarted on other nodes in the cluster.

Nutanix supports high availability (HA) for VMs by automatically restarting them on other nodes in the cluster in case of a node failure. The cluster CPU and memory utilization will increase temporarily until the failed node is recovered, but there will be no user impact.

NO.46 An administrator is unable to discover a Nutanix-hosted iSCSI block device allocated to a bare-metal host.
What is causing this issue?

Jumbo frames has not been configured on the switch

External client access has not been enabled for the host

Network segmentation has not been enabled

External host IP address is not in the Filesystem Whitelist

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. Reference: https://www.nutanix.com/content/dam/nutanix/resources/datasheets/ds-nutanix-acropolis-block-services.pdf (page 4) https://portal.nutanix.com/page/documents/solutions/details?targetId=BP-2049-Nutanix-Volumes:BP-2049-Nutanix-Volumes (page 7)

NO.47 What happens to images that are imported into Prism Central?

Copied to the Prism Central image repository

Remain in the source duster after import

Copied to all clusters managed by Prism Central

Deleted from the source cluster after import

The Prism Central image repository is a centralized location for storing virtual machine images that can be used to deploy VMs to any cluster managed by Prism Central. When an image is imported into Prism Central, a copy of the image is made and stored in the repository, so that it can be easily accessed and deployed to any cluster as needed.
The original image file typically remains in the source cluster after it is imported into Prism Central, unless it is explicitly deleted. Similarly, the image copy in the Prism Central repository is not automatically copied to all clusters managed by Prism Central, but can be used to deploy new VMs on any cluster as needed.

NO.48 Which Nutanix storage efficiency feature is suitable for nearly every workload?

Erasure Coding

Deduplication

Compression

Thick Provisioning

Compression is a Nutanix storage efficiency feature that is suitable for nearly every workload, as it reduces the amount of data stored on disk without impacting performance. Erasure Coding, Deduplication, and Thick Provisioning are other storage efficiency features, but they have different trade-offs and use cases. Reference: https://www.nutanix.com/content/dam/nutanix/resources/misc/ebg-nca-6-5.pdf (page 30)

NO.57 A single host in a four-node AHV-based cluster experiences a complete network failure.
If more than enough resources exist in the cluster to tolerate a node failure, what happens to the user VMs running on that host?

VMs remain down until network connectivity is restored.

VMs stay up, but are unreachable until connectivity is restored.

VMs automatically restart on the three remaining hosts.

VMs are live-migrated to the three remaining hosts.

If a single host in an AHV-based cluster experiences a complete network failure, and if there are enough resources available in the cluster to tolerate a node failure, then the user VMs running on the failed host will be automatically live-migrated to the remaining three hosts in the cluster. This ensures that the VMs stay up and running even if one of the hosts fails. Reference: https://portal.nutanix.com/page/documents/details?targetId=Platform-Administrator-Guide-v5_7:pag-vm-migrate-c.html

NO.58 Which feature enables Image Placement Policies to be mapped to target clusters?

YAML

Labels
