VMCE Replication and Recovery 2 — Questions and Answers
Question 1: What is the purpose of the 'replica seeding' feature in Veeam replication?
- To encrypt replica data at rest
- To pre-populate replica VM data from a backup file to reduce WAN traffic (Correct answer)
- To automatically test replicas on a schedule
- To synchronize replica metadata with vCenter
Correct answer: To pre-populate replica VM data from a backup file to reduce WAN traffic
Replica seeding lets you ship a backup to the DR site and use it as the initial replica, drastically reducing initial replication bandwidth over WAN.
Question 2: When performing a Failover to a VM replica, what is the state of the original production VM?
- It is automatically powered off by Veeam before failover
- It remains running unless you manually power it off (Correct answer)
- It is deleted from the production site
- It is suspended and snapshotted by Veeam
Correct answer: It remains running unless you manually power it off
Veeam does not automatically power off the production VM during failover; the administrator must manually manage the production VM to avoid split-brain.
Question 3: Which replication mode synchronizes only changed blocks since the last replication cycle?
- Full replication
- Incremental replication (Correct answer)
- Synthetic replication
- Reverse replication
Correct answer: Incremental replication
Incremental replication transfers only the changed blocks tracked via CBT since the last run, minimizing bandwidth and time.
Question 4: What happens to replication restore points when the 'retain days' limit is exceeded?
- Veeam archives them to object storage automatically
- The oldest restore points are removed by Veeam automatically (Correct answer)
- Replication jobs pause until manual cleanup
- Old restore points are merged into a single synthetic point
Correct answer: The oldest restore points are removed by Veeam automatically
Veeam automatically removes the oldest replica restore points once the configured retention limit is reached, keeping the replica chain within the defined window.
Question 5: In a Veeam replication job, what does the 'replica mapping' option allow you to do?
- Map source VM disks to different datastores at the target
- Re-use an existing VM at the target as the replica instead of creating a new one (Correct answer)
- Map replication traffic to a specific network interface
- Define CPU and memory allocation for the replica VM
Correct answer: Re-use an existing VM at the target as the replica instead of creating a new one
Replica mapping lets you point a replication job to an already-existing VM at the target site, using it as the starting point instead of creating a fresh replica.
Question 6: Which Veeam component is responsible for tracking changed blocks on a VMware VM during replication?
- Veeam Backup Proxy
- VMware Changed Block Tracking (CBT) (Correct answer)
- Veeam Guest Interaction Proxy
- Veeam WAN Accelerator
Correct answer: VMware Changed Block Tracking (CBT)
VMware's built-in Changed Block Tracking (CBT) mechanism is leveraged by Veeam to identify which disk blocks changed since the last replication cycle.
Question 7: What is the maximum number of restore points that Veeam supports for VM replicas?
- 7
- 14
- 28 (Correct answer)
- 30
Correct answer: 28
Veeam supports up to 28 restore points for VM replicas, allowing you to roll back a replica to any of those points.
