VMware Cloud Director Specialist (2022) — Question 109

The architect of a multi-site VMware Cloud Foundation solution is tasked with ensuring that the prerequisites for vSAN data at rest encryption have been achieved. The existing design calls for use of the vSphere Native Key Provider. NSX-T is configured with Federation, and both sites benefit from a stretched T0 and T1 network topology.
A new security policy requires the use of vSphere Virtual Machine encryption, in addition to the at-rest encryption already configured. During a failover test from Site-A to Site-B using Site Recovery Manager, the virtual machines were unable to power-on.
How does the design need to be changed to support the new requirement?

Answer options

• A. Ensure that a TPM 2.0 certified module is installed on all ESXi hosts at Site-B.
• B. Use a third-party KMS solution at each site.
• C. Use a third-party KMS solution that allows for key replication.
• D. Ensure that the Site Recovery Manager service account has Cryptographer.ReadKeyServersInfo privileges.

Correct answer: C

Explanation

The correct answer is C because a third-party KMS solution that allows for key replication is necessary to ensure that the encryption keys are available at both sites during a failover. Option A is incorrect as a TPM 2.0 module is not specifically required for this scenario. Option B does not address the key replication requirement that is essential for successful failover. Option D pertains to permissions but does not resolve the encryption key availability issue.
