B. Create ESXi host security certificates using the SSL. Thumbprint mode to ensure consistency among all hosts.

C. Add the ESXi hosts to vCenter Server before updating the VMCA root certificate on the PSC.

D. Make VMCA an Intermediate Certificate Authority to ensure each added ESXi hosts receives the same certificate.

B. Insufficient memory for Auto Deploy to complete the upgrade.

C. Insufficient memory in vCenter Server to complete the upgrade.

D. Insufficient memory for Update Manager to complete the upgrade.

During a vCenter Server upgrade, an ESXi 6.x host in a High Availability (HA) cluster fails.

Which statement is true?

A. HA will fail the virtual machines over to an available host during the vCenter Server upgrade process.

B. HA is unavailable during the vCenter Server upgrade process.

C. HA will fail the virtual machines over to an available host after the vCenter Server upgrade completes.

D. HA will successfully vMotion the virtual machines during the host failure.
