VMCE Replication and Disaster Recovery 3 — Questions and Answers
Question 1: After a Failover in Veeam, what are the two actions you can take to conclude the failover process?
- Replicate Again or Delete Replica
- Failover Commit or Undo Failover (Correct answer)
- Failback or Planned Failover
- Restore or Migrate
Correct answer: Failover Commit or Undo Failover
After failover, you either commit (making the replica the new production VM permanently) or undo failover (reverting to the original source VM).
Question 2: What is the role of the Veeam Backup & Replication 'Network Mapping' feature during failover?
- It maps vSphere port groups to Hyper-V virtual switches
- It automatically remaps replica VM network adapters to DR-site networks when the replica is powered on (Correct answer)
- It configures static routes on the DR network
- It bridges production and DR VLANs for live migration
Correct answer: It automatically remaps replica VM network adapters to DR-site networks when the replica is powered on
Network Mapping ensures that when a replica is powered on during failover, its NICs are connected to the correct DR-site networks rather than production networks.
Question 3: Which Veeam replication mode sends only changed data blocks after the initial full replication run?
- Full replication mode
- Incremental replication mode using CBT (Correct answer)
- Synthetic full mode
- Forever-forward incremental mode
Correct answer: Incremental replication mode using CBT
After the initial seed, Veeam uses VMware Changed Block Tracking (CBT) or Hyper-V RCT to replicate only changed blocks, drastically reducing bandwidth usage.
Question 4: What happens to replica restore points (snapshots) when you run a 'Failover Commit' in Veeam?
- All snapshots are preserved for future rollback
- All replica restore point snapshots are deleted, leaving a clean running VM (Correct answer)
- Snapshots are converted into VBK files on the repository
- Only the oldest snapshot is removed
Correct answer: All replica restore point snapshots are deleted, leaving a clean running VM
Failover Commit consolidates and removes all replica snapshots, leaving a clean production-like VM at the DR site with no pending snapshot chain.
Question 5: In Veeam's Failback workflow, what does 'Failback to the original VM' specifically do?
- Creates a brand-new VM on the production site
- Restores changes made on the replica back to the original source VM location (Correct answer)
- Migrates the replica using Storage vMotion to production storage
- Recreates the original VM from the most recent repository backup
Correct answer: Restores changes made on the replica back to the original source VM location
Failback to the original VM reverses the replication direction, sending delta changes from the replica back to the original source VM so production can resume where it left off.
Question 6: Which Veeam feature lets you automate the execution of multiple failover steps — including VM power order, delays, and scripts — into a single orchestrated workflow?
- Replication Job Schedule
- Failover Plan (Correct answer)
- SureReplica
- Instant VM Recovery
Correct answer: Failover Plan
A Failover Plan in Veeam lets you define the order, delays, and scripts for powering on multiple replica VMs, providing orchestrated DR with a single-click execution.
Question 7: When configuring a replication job in Veeam, what does enabling 'Application-aware processing' ensure for replicas?
- That replicas are encrypted with AES-256
- That VSS-consistent snapshots are used so replicated data is application-consistent (Correct answer)
- That applications are automatically started in alphabetical order after failover
- That replica snapshots are stored on a separate repository
Correct answer: That VSS-consistent snapshots are used so replicated data is application-consistent
Application-aware processing uses Microsoft VSS (or Linux scripts) during snapshot creation to ensure the replica contains a transactionally consistent state of applications like SQL Server or Active Directory.
