Accepted Answer

HA automatically restarts virtual machines on healthy hosts in the event of a host failure, minimizing downtime.

Question 18

What is Transparent Page Sharing (TPS) in VMware vSphere, and how does it help optimize memory utilization in virtualized environments?

Accepted Answer

TPS deduplicates identical memory pages across virtual machines to conserve memory resources.

Question 19

Accepted Answer

CPU contention due to VMs competing for CPU resources

Question 20

What is the purpose of vSphere Data Protection (VDP) in VMware vSphere, and how does it facilitate backup and recovery operations?

Accepted Answer

VDP provides a centralized backup solution for vSphere environments, offering full and incremental backups of VMs.

Question 21

What is vSphere Replication in VMware vSphere, and how does it contribute to data protection and disaster recovery?

Accepted Answer

vSphere Replication offers continuous data protection by capturing and replicating virtual machine changes to a secondary site at predefined intervals.
