Which two initial cluster configuration tasks were missed during the deployment process? (Choose two.)

  1. Host password changes
  2. Password policy changes
  3. BIOS password changes
  4. CVM password changes

Answer(s): A,D

Explanation:

According to the image description, the exhibit shows a screenshot of a computer screen with a table of data. The table has 6 columns and 4 rows. The columns are labeled "Date", "Time", "Status", "Details", "Configuration", and "Duration". The rows contain information about different configurations and their statuses. The background is a light blue color. There is a pop-up message on the bottom right corner of the screen that reads "This question has been answered. Click here to enable the edit button."

Based on the table data, it seems that the screenshot is taken from the Prism Central web console, showing the results of a cluster health check report. The report shows that there are four failed checks: Host Password Policy, CVM Password Policy, NTP Configuration, and Cluster Time Skew2. These checks indicate that some initial cluster configuration tasks were missed during the deployment process.

The Host Password Policy check verifies that the host passwords are not set to default values and are compliant with the password policy defined in Prism Central3. The CVM Password Policy check verifies that the CVM passwords are not set to default values and are compliant with the password policy defined in Prism Central4. These checks are important for ensuring the security and compliance of the cluster. Therefore, changing the host and CVM passwords from their default values and following the password policy guidelines are two initial cluster configuration tasks that were missed.

An administrator needs to configure a new subnet on an AHV cluster and want to ensure that VMs will automatically be assigned an IP address at creation time.

Which type of network does the administrator need to create?

  1. Dynamic Network
  2. Unmanaged Network
  3. Managed Network
  4. DHCP Network

Answer(s): C

Explanation:

A managed network is a type of network that can be created on an AHV cluster and allows VMs to automatically be assigned an IP address at creation time. A managed network uses the Nutanix IP Address Management (IPAM) service, which provides DHCP and DNS functionality for the VMs on the network. A managed network can be configured with a subnet range, a default gateway, and DNS servers. The IPAM service will allocate IP addresses from the subnet range to the VMs and register their hostnames in the DNS servers. The IPAM service will also release the IP addresses when the VMs are deleted or moved to another network1.

To create a managed network on an AHV cluster, the administrator can use Prism Element or Prism Central. The steps are as follows2:

In Prism Element, go to the Network Configuration page and click Create Network.

In Prism Central, go to the Networks page and click Create.

Enter a name and description for the network.

Select Managed as the network type.

Enter the subnet range, default gateway, and DNS servers for the network.

Optionally, enable VLAN tagging and enter a VLAN ID for the network.

Click Save.

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?

  1. Setting the cluster time zone via PC GUI
  2. Setting the cluster time zone via CVM NCLI
  3. Setting the cluster time zone via PE GUI
  4. Setting the cluster time zone via CVM ACLI

Answer(s): B

Explanation:

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=<timezone> to change the cluster time zone, where <timezone> is a valid time zone identifier (for example, America/New_York).

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.

Which AOS process determine if an I/O from a user will be written to OpLog or to an Extent Store?

  1. Stargate
  2. Curtor
  3. Cassandara
  4. Zeus

Answer(s): A

Explanation:

Stargate is the AOS process that handles all I/O operations for the cluster. It is responsible for determining whether an I/O from a user will be written to the OpLog or to the Extent Store, based on the type and size of the I/O. Stargate also performs data tiering, compression, deduplication, and erasure coding1. Stargate runs on every CVM and communicates with other Stargates to ensure data locality and redundancy2.
