Hyper-V & Server Virtualization Flashcards

What is the purpose of a Hyper-V snapshot (checkpoint)?

Answer: To capture the VM's state at a point in time for potential rollback

A Hyper-V snapshot (checkpoint) captures the state, data, and hardware configuration of a VM at a specific moment, enabling rollback if needed.

Which type of Hyper-V migration moves a running virtual machine to another host with no user-visible downtime?

Answer: Live migration

Live Migration transfers a powered-on VM between Hyper-V hosts by copying memory state while the VM continues running, resulting in no downtime.

What is required to perform Live Migration between two standalone (non-clustered) Hyper-V hosts in Windows Server 2012?

Answer: Active Directory domain membership plus shared storage or SMB 3.0

Non-clustered Live Migration requires both hosts to be in the same AD domain for Kerberos authentication plus either shared storage or SMB 3.0 file shares.

Which Windows Server 2012 clustering technology provides high availability for Hyper-V virtual machines?

Answer: Failover Clustering

Failover Clustering enables Hyper-V VMs to automatically restart on another cluster node if the hosting server fails, providing high availability.

What is Hyper-V Replica in Windows Server 2012?

Answer: An asynchronous VM replication feature that copies VMs to a secondary site for disaster recovery

Hyper-V Replica asynchronously replicates virtual machines to a secondary Hyper-V host or site for disaster recovery without requiring shared storage.

What is the default replication interval for Hyper-V Replica in the original Windows Server 2012 release?

Answer: 5 minutes

The default Hyper-V Replica replication interval in Windows Server 2012 is 5 minutes; the 30-second option was added in Windows Server 2012 R2.
