VMCE Replication and Recovery 3 — Questions and Answers
Question 1: What is 'Planned Failover' in Veeam and when should it be used?
- An automatic failover triggered by a heartbeat timeout
- A controlled switchover to the replica performed before a planned maintenance or migration (Correct answer)
- A test failover that automatically reverts after 24 hours
- A failover that only works when the production VM is powered off
Correct answer: A controlled switchover to the replica performed before a planned maintenance or migration
Planned Failover is a graceful migration to the replica where Veeam performs a final sync of the source VM, minimizing data loss, ideal for scheduled maintenance windows.
Question 2: After a successful Failback in Veeam, what is the recommended next step?
- Delete the replica VM from the DR site
- Commit the failback to make the production VM active and re-enable replication (Correct answer)
- Re-run a full replication job to rebuild the replica chain
- Manually copy replica restore points back to production
Correct answer: Commit the failback to make the production VM active and re-enable replication
After failback, you commit it to confirm the production VM is now authoritative, after which Veeam can resume normal replication from the production site.
Question 3: Which recovery option allows you to restore a VM replica to a specific point-in-time state without full failover?
- Instant VM Recovery
- Restore from replica restore point (Correct answer)
- Replica rollback (undo failover equivalent at replica level)
- Staged restore
Correct answer: Restore from replica restore point
Veeam lets you restore a VM directly from a specific replica restore point, effectively rolling the replica back to a previous state without initiating a full failover.
Question 4: What network mapping setting in a Veeam replication job ensures the replica VM connects to the correct isolated test network?
- Target network override in job settings
- Re-IP rules configured in the job
- Network mapping in the replication job's network settings (Correct answer)
- Virtual lab network settings
Correct answer: Network mapping in the replication job's network settings
Network mapping in the replication job's network settings maps source VM networks to target networks, ensuring the replica connects to the appropriate network at the DR site.
Question 5: When using Veeam's 'Re-IP' feature during failover, what does it accomplish?
- It reassigns the MAC address of the replica VM's NIC
- It automatically changes the IP address of the replica VM to match DR site addressing (Correct answer)
- It updates DNS records in Active Directory
- It enables DHCP on the replica VM's network adapter
Correct answer: It automatically changes the IP address of the replica VM to match DR site addressing
Re-IP rules change the IP configuration of a Windows or Linux VM replica during failover so the VM operates correctly with DR site network addressing.
Question 6: In Veeam replication, what is 'WAN Acceleration' primarily designed to optimize?
- CPU usage on the source proxy during replication
- Deduplication and compression of replication traffic over a WAN link (Correct answer)
- Encryption of replication data in transit
- Scheduling of replication jobs across time zones
Correct answer: Deduplication and compression of replication traffic over a WAN link
WAN Acceleration uses global deduplication and compression caching on both source and target WAN accelerators to significantly reduce data transferred over slow WAN links.
Question 7: What is the effect of enabling 'application-aware processing' on a replication job for a SQL Server VM?
- It backs up SQL transaction logs separately to the Veeam repository
- It ensures the VM is quiesced at the application level for a crash-consistent SQL replica (Correct answer)
- It truncates SQL transaction logs after each replication cycle
- It creates a VSS snapshot of SQL databases independently of the VM snapshot
Correct answer: It ensures the VM is quiesced at the application level for a crash-consistent SQL replica
Application-aware processing invokes VSS inside the guest to quiesce SQL Server, producing an application-consistent replica that can be safely recovered without transaction log issues.
