Task 15

An administrator found a CentOS VM, Cent_Down, on the cluster with a corrupted network stack. To correct the issue, the VM will need to be restored from a previous snapshot to become reachable on the network again.

VM credentials:

Username: root

Password: nutanix/4u

Restore the VM and ensure it is reachable on the network by pinging 172.31.0.1 from the VM.

Power off the VM before proceeding.

A. Answer: See the Explanation for step by step solution.

Reveal model answer Close model answer

To restore the VM and ensure it is reachable on the network, you can follow these steps: Log in to the Web Console of the cluster where the VM is running. Click on Virtual Machines on the left menu and find Cent_Down from the list. Click on the power icon to power off the VM.
Click on the snapshot icon next to the power icon to open the Snapshot Management window.
Select a snapshot from the list that was taken before the network stack was corrupted. You can use the date and time information to choose a suitable snapshot. Click on Restore VM and confirm the action in the dialog box. Wait for the restore process to complete.
Click on the power icon again to power on the VM. Log in to the VM using SSH or console with the username and password provided. Run the command ping 172.31.0.1 to verify that the VM is reachable on the network. You should see a reply from the destination IP address.

Go to VMS from the prism central gui Select the VMand go to More -> Guest Shutdown
Go to Snapshots tab and revert to latest snapshot available power on vm and verify if ping is working

Task 12

An administrator needs to create a report named VMs_Power_State that lists the VMs in the cluster and their basic details including the power state for the last month.

No other entities should be included in the report.

The report should run monthly and should send an email [email protected] it runs.

Generate an instance of the report named VMs_Power_State as a CSV and save the zip file as Desktop
\Files\VMs_Power_state.zip

Note: Make sure the report and zip file are named correctly. The SMTP server will not be configured.

A. Answer: See the Explanation for step by step solution.

Task 1

An administrator has been asked to configure a storage for a distributed application which uses large data sets across multiple worker VMs.

The worker VMs must run on every node. Data resilience is provided at the application level and low cost per GB is a Key Requirement.

Configure the storage on the cluster to meet these requirements. Any new object created should include the phrase Distributed_App in the name.

A. Answer: See the Explanation for step by step solution.

Reveal model answer Close model answer

To configure the storage on the cluster for the distributed application, you can follow these steps:
Log in to Prism Element of cluster A using the credentials provided. Go to Storage > Storage Pools and click on Create Storage Pool. Enter a name for the new storage pool, such as

Distributed_App_Storage_Pool, and select the disks to include in the pool. You can choose any combination of SSDs and HDDs, but for low cost per GB, you may prefer to use more HDDs than SSDs.
Click Save to create the storage pool.
Go to Storage > Containers and click on Create Container. Enter a name for the new container, such as Distributed_App_Container, and select the storage pool that you just created, Distributed_App_Storage_Pool, as the source. Under Advanced Settings, enable Erasure Coding and Compression to reduce the storage footprint of the data. You can also disable Replication Factor since data resilience is provided at the application level. These settings will help you achieve low cost per GB for the container.
Click Save to create the container.
Go to Storage > Datastores and click on Create Datastore. Enter a name for the new datastore, such as Distributed_App_Datastore, and select NFS as the datastore type. Select the container that you just created, Distributed_App_Container, as the source.
Click Save to create the datastore.
The datastore will be automatically mounted on all nodes in the cluster. You can verify this by going to Storage > Datastores and clicking on Distributed_App_Datastore. You should see all nodes listed under
Hosts.
You can now create or migrate your worker VMs to this datastore and run them on any node in the cluster.
The datastore will provide low cost per GB and high performance for your distributed application.
