  1. How do you interpret the flagged anomalies?

    • A) Review the anomaly reports in File Analytics and check the audit trails for the suspicious files.
    • B) Dismiss the anomaly alerts and assume it's a false positive, as no issues have been reported.
    • C) Disable the anomaly detection temporarily while you investigate the file permissions.

  2. If File Analytics confirms that ransomware is encrypting files, what is your next step?

    • A) Enable ransomware protection in File Analytics and block the affected accounts from further access.
    • B) Manually shut down the file server and delete the infected files.
    • C) Reset the anomaly detection settings and rerun the analysis.

Step 5: Sizing, Scaling, and High Availability

I’ll create scenarios where you need to think through scaling decisions and high availability setups, such as when to scale up or out, or how to implement redundancy effectively in Nutanix environments.

Example Scaling Scenario:

Scenario:
A new project requires doubling the storage capacity of your existing Nutanix Files setup. The project also requires ensuring high availability (HA) for both the file shares and the Nutanix Volumes running on the cluster.

  1. How do you scale Nutanix Files to meet the new storage demands?

    • A) Add more FSVMs and scale the file server cluster to accommodate the increased storage.
    • B) Expand the existing FSVMs by adding more virtual CPUs and RAM.
    • C) Increase the storage capacity on the existing nodes without adding FSVMs, and adjust the shares accordingly.

  2. What should be your approach to ensure high availability for Nutanix Volumes?

    • A) Enable multi-pathing for the iSCSI initiators on each client to ensure failover in case of node failure.
    • B) Configure backup volumes on a different Nutanix cluster and sync data manually.
    • C) Scale out the Nutanix Volumes by adding more capacity and relying on Nutanix's built-in data replication for failover.
