VMCE Replication and Recovery 4 — Questions and Answers
Question 1: What occurs when you select 'Undo Failover' in Veeam after a failover has been initiated?
- The replica VM is deleted and a new replication cycle begins from scratch
- The replica is rolled back to its pre-failover state and the original production VM is restored as primary (Correct answer)
- The failover is committed and the production VM is permanently replaced
- All replication restore points newer than the failover point are removed
Correct answer: The replica is rolled back to its pre-failover state and the original production VM is restored as primary
Undo Failover reverts the replica to its last replication state before the failover, discarding changes made while the replica was running, and allows replication to resume normally.
Question 2: In a Veeam replication job targeting a Hyper-V environment, which component performs the data reading at the source?
- Veeam Guest Interaction Proxy
- Off-host backup proxy using Hyper-V VSS provider
- Source-side Veeam Backup Proxy deployed on the Hyper-V host (Correct answer)
- Veeam Mount Server
Correct answer: Source-side Veeam Backup Proxy deployed on the Hyper-V host
For Hyper-V replication, a Veeam Backup Proxy deployed on or near the Hyper-V host reads source VM data using the Hyper-V VSS provider.
Question 3: Which Veeam feature enables you to test replica recoverability without impacting production or the replica itself?
- SureReplica (Virtual Lab-based automated replica testing) (Correct answer)
- Instant VM Recovery from replica
- Failover Test mode with network isolation
- Replica verification via hash comparison
Correct answer: SureReplica (Virtual Lab-based automated replica testing)
SureReplica uses Veeam's Virtual Lab to automatically power on and test replicas in an isolated network sandbox, verifying recoverability without touching the live replica.
Question 4: When configuring a Veeam replication job, what does the 'Source proxy' setting control?
- Which Veeam server reads data from the source VM and sends it toward the target (Correct answer)
- Which credentials are used to authenticate to the source hypervisor
- The compression level applied before data leaves the source site
- The scheduling priority of the replication job at the source
Correct answer: Which Veeam server reads data from the source VM and sends it toward the target
The Source proxy is the Veeam component that reads VM data from the source datastore and transmits it (directly or via WAN accelerator) to the target proxy at the DR site.
Question 5: What is the RPO (Recovery Point Objective) achievable with Veeam's continuous replication mode for VMware VMs?
- 15 minutes minimum
- 5 minutes minimum
- Near-zero seconds using vSphere Replication integration (Correct answer)
- 1 hour minimum due to snapshot consolidation overhead
Correct answer: Near-zero seconds using vSphere Replication integration
By integrating with VMware vSphere Replication, Veeam can achieve near-zero RPO for VMware VMs, going well below the 15-minute minimum of standard Veeam replication jobs.
Question 6: After a Failback operation completes in Veeam, what is the status of the replica VM at the DR site?
- It is deleted automatically by Veeam
- It is powered off and retained as a standby replica (Correct answer)
- It remains powered on as a secondary production VM
- It is converted into a backup repository
Correct answer: It is powered off and retained as a standby replica
After a successful failback commit, the DR replica VM is powered off and kept as a standby replica, ready for the next replication cycle from the recovered production site.
Question 7: Which Veeam recovery option provides the fastest RTO when recovering a VM from a replica?
- Full VM restore from replica to production storage
- Instant VM Recovery from replica running directly on DR datastore (Correct answer)
- Restore to a new location using replica restore points
- Publishing the replica VM using Veeam DataLabs
Correct answer: Instant VM Recovery from replica running directly on DR datastore
Instant VM Recovery from a replica powers the VM directly from the replica datastore within minutes, providing the fastest possible RTO while storage vMotion completes in the background.
