• Question 21:

  A systems engineer is deploying a VxRail cluster. They want to ensure that configuration issues can be avoided when expanding this cluster.

  Which actions need to be performed?

  A. Verify VxRail nodes are racked and connected to the ToR switches Validate the network environment

  B. Validate that no pending and unfinished jobs are running on the servers Verify that the server and storage components are working properly

  C. Validate that the latest updates and patches are installed in the system Validate that no pending and unfinished jobs are running on the servers

  D. Verify the configuration settings initially captured in PEQ Validate the storage environment

  Correct Answer: C

• Question 22:

  What is a difference between vSAN Data-In-Transit Encryption and vSAN Data-At-Rest-Encryption?

  A. Data-In-Transit Encryption: Encrypts traffic between VMs and the VxRail nodes Data-At-Rest Encryption: Encrypts traffic between VxRail nodes only

  B. Data-In-Transit Encryption: Does not require a Key Management Server Data-At-Rest Encryption: Requires a Key Management Server

  C. Data-In-Transit Encryption: Key Management Server must reside on the vSAN cluster Data-At-Rest Encryption: Key Management Server can reside on the vSAN cluster

  D. Data-In-Transit Encryption: Addresses fear of media theft Data-At-Rest Encryption: Addresses fear of rogue administrators

  Correct Answer: A
