VMCE Replication and Disaster Recovery 2 — Questions and Answers
Question 1: What is the purpose of a replication seed in Veeam Backup & Replication?
- To encrypt replicated VM data in transit
- To reduce network traffic by using an existing backup file as the initial replica baseline (Correct answer)
- To schedule replication jobs during off-peak hours
- To validate replica integrity after each replication cycle
Correct answer: To reduce network traffic by using an existing backup file as the initial replica baseline
A replication seed allows Veeam to use an existing backup file transported via removable media as the initial copy, drastically reducing WAN traffic for the first replication run.
Question 2: Which Veeam component is responsible for processing data during a replication job at the target site?
- Veeam Backup Server
- Source-side proxy server
- Target-side proxy server (Correct answer)
- Veeam Enterprise Manager
Correct answer: Target-side proxy server
The target-side proxy server receives and writes replica data to the datastore at the DR site during a replication job.
Question 3: When performing a Planned Failover in Veeam, what happens to the source VM?
- It is immediately deleted from the production site
- It is shut down gracefully before the replica is powered on (Correct answer)
- It continues running in parallel with the replica
- It is converted to a backup file
Correct answer: It is shut down gracefully before the replica is powered on
Planned Failover gracefully shuts down the source VM, synchronizes the final changes to the replica, and then powers on the replica to minimize data loss.
Question 4: What does the 'Replica mapping' option allow you to do in Veeam?
- Map network adapters on replicas to DR site networks
- Associate an existing VM at the DR site as the target replica instead of creating a new one (Correct answer)
- Define IP address mappings for failover
- Link a replica to multiple source VMs
Correct answer: Associate an existing VM at the DR site as the target replica instead of creating a new one
Replica mapping lets you point a replication job at a pre-existing VM on the target side, useful when an initial copy was seeded manually.
Question 5: How many restore points (replica restore points) does Veeam keep for a replica by default, and what are they stored as?
- 3 restore points stored as full VM snapshots
- 7 restore points stored as VMware or Hyper-V snapshots on the replica VM (Correct answer)
- 14 restore points stored in a VBK file on the repository
- 30 restore points stored as incremental backup files
Correct answer: 7 restore points stored as VMware or Hyper-V snapshots on the replica VM
Veeam stores replica restore points as native hypervisor snapshots (VMware or Hyper-V) on the replica VM itself, with a configurable number defaulting to 7.
Question 6: Which failover option in Veeam allows you to test DR readiness without affecting production or committing any changes permanently?
- Planned Failover
- Failover Commit
- Failback
- Failover Test (Virtual Lab) (Correct answer)
Correct answer: Failover Test (Virtual Lab)
The Failover Test (Virtual Lab) option powers on the replica in an isolated network sandbox so DR procedures can be validated without any production impact.
Question 7: In Veeam replication, what is 'WAN acceleration' primarily designed to optimize?
- CPU usage on the source proxy
- Deduplication and compression of data transferred over high-latency WAN links (Correct answer)
- The speed of VMware snapshot creation
- Encryption key exchange between source and target
Correct answer: Deduplication and compression of data transferred over high-latency WAN links
WAN acceleration uses global data deduplication caches on both source and target WAN accelerators to minimize the amount of data sent over high-latency WAN links.
