An administrator wants to expand the Failure Domain level of a cluster. What two options are available? (Choose two.)
Correct Answer:
CD
Nutanix clusters are resilient to a drive, node, block, and rack failures because they use redundancy factor 2 by default, allowing Nutanix clusters to self-heal2. Failure scenarios can be thought of in terms of fault domains, which are the physical or logical parts of a computing environment or location that are adversely affected when a device or service experiences an issue or outage3. There are four fault domains in a Nutanix cluster: Disk, Node, Block, and Rack4. Block and Rack are two options that are available for expanding the failure domain level of a cluster. Block fault tolerance is enabled by default and ensures that data is replicated across different blocks in a cluster5. Rack fault tolerance has to be configured manually and ensures that data is replicated across different racks in a cluster4.

Which command should an administrator run from the CLI to view the uplink state of all AHV nodes in the cluster?
Correct Answer:
C
According to section 4 of the exam blueprint guide1, one of the topics covered is AHV networking components and configuration settings. One of these components is Open vSwitch (OVS), which is a software switch that provides network connectivity between VMs and physical networks. OVS has two types of ports:
✑ Uplink ports: These are physical ports that connect to external networks or
switches.
✑ Internal ports: These are virtual ports that connect to VMs or other internal networks.
To view the uplink state of all AHV nodes in the cluster, an administrator can use the manage_ovs command with the show_uplinks option. This command displays information such as port name, link state, speed, duplex mode, MTU size, bond mode, and bond status. However, this command only works on a single node. To run the command on all nodes in the cluster, an administrator can use the allssh command, which executes a command on all CVMs in parallel. Therefore, the correct command is:
allssh manage_ovs show_uplinks

An administrator was reviewing various AOS logs when a it was noticed that the time of the logs were off by several hours.
Which initial step was missed during the post process cluster configuration?
Correct Answer:
B
The cluster time zone is a setting that determines the time zone used by all CVMs in the cluster. The cluster time zone affects the timestamps of Nutanix logs, events, alerts, and reports. The cluster time zone also affects the scheduling of tasks such as snapshots, replication, and upgrades. By default, the cluster time zone is set to UTC (Coordinated Universal Time) when the cluster is created3.
To change the cluster time zone, the administrator needs to use the ncli (Nutanix command-line interface) on any CVM in the cluster. The steps are as follows4:
✑ Log in to any CVM using SSH.
✑ Run ncli cluster get-timezone to check the current cluster time zone.
✑ Run ncli cluster set-timezone timezone=
✑ Run ncli cluster get-timezone again to verify that the cluster time zone has been changed.
Note that changing the cluster time zone does not affect the time zone of Prism Element or Prism Central VMs. To change their time zone, the administrator needs to use Prism Element UI or Prism Central UI respectively5.

The customer is seeing high memory utilization on a mission critical VM. Users report that the application is unavailable. The guest OS does not support hot add components.
How should the administrator fix this issue?
Correct Answer:
B
The best way to fix this issue is to increase the amount of memory assigned to the VM from the Prism web console. This option allows the administrator to modify the VM configuration without accessing the CVM or shutting down the VM. The Prism web console provides a simple and intuitive interface for managing Nutanix clusters and VMs1. To change the memory allocation for a VM, the administrator can follow these steps2:
✑ Go to the VM dashboard
✑ Select the VM from the VMs list
✑ Choose Update
✑ Adjust the amount of memory assigned to the VM
✑ Click Save
