VMCE Replication and Recovery 5 — Questions and Answers
Question 1: What is the purpose of 'replica target datastore free space' threshold in Veeam replication job settings?
- It pauses replication if the source datastore runs low on space
- It warns or stops the job when the DR datastore has insufficient free space for replica operations (Correct answer)
- It limits the maximum size of the replica VM disk
- It triggers automatic thin-provisioning on the replica VM
Correct answer: It warns or stops the job when the DR datastore has insufficient free space for replica operations
Veeam monitors DR target datastore free space and can warn or abort the replication job if space falls below the configured threshold, preventing failed replications.
Question 2: In Veeam's replication architecture, what role does the 'target proxy' play?
- It reads data from the source VM at the production site
- It receives data from the source proxy and writes it to the replica VM at the DR site (Correct answer)
- It manages scheduling of replication jobs from the Veeam Backup Server
- It compresses replica restore points on the DR datastore
Correct answer: It receives data from the source proxy and writes it to the replica VM at the DR site
The target proxy receives the replicated data stream from the source proxy and writes the VM blocks to the replica datastore at the DR site.
Question 3: What Veeam capability allows you to failover multiple VMs simultaneously as a coordinated group?
- Multi-VM Instant Recovery
- Failover Plan (Correct answer)
- Replica Group Policy
- Coordinated Replication Job
Correct answer: Failover Plan
A Failover Plan in Veeam lets you define an ordered group of VMs to fail over together, including boot delays and sequencing, enabling a full DR site activation in one action.
Question 4: When Veeam performs Failback using the 'Restore to original location' option, what data source does it use by default?
- The most recent backup in the Veeam repository
- The running replica VM at the DR site (Correct answer)
- A new replication job initiated from DR to production
- A full replication reseed from the production hypervisor
Correct answer: The running replica VM at the DR site
Failback using 'Restore to original location' uses the running replica VM as the source, reverse-replicating its current state back to the original production location.
Question 5: Which setting in a Veeam replication job controls how many simultaneous VM replication tasks can run within that job?
- Concurrent tasks limit on the Veeam Backup Server
- Max concurrent tasks per job configured in job advanced settings (Correct answer)
- The number of available source proxies
- The target datastore IOPS limit
Correct answer: Max concurrent tasks per job configured in job advanced settings
The max concurrent tasks setting in the job's advanced settings controls how many VMs in the job replicate simultaneously, balancing speed against resource consumption.
Question 6: What is 'Replica Failover Test' isolation network used for in Veeam's Virtual Lab?
- To route production traffic to the replica VM during testing
- To prevent the replica VM from communicating with production systems while powered on for testing (Correct answer)
- To enable WAN acceleration during test failovers
- To apply Re-IP rules without modifying the replica VM configuration
Correct answer: To prevent the replica VM from communicating with production systems while powered on for testing
The isolated network in Virtual Lab ensures that when a replica is powered on for testing, it cannot reach production systems, preventing duplicate IPs or accidental data writes.
Question 7: In Veeam replication, which VMware feature must be enabled on source VMs for incremental replication to function correctly?
- vSphere Storage DRS
- Changed Block Tracking (CBT) (Correct answer)
- vSphere Fault Tolerance
- Storage vMotion
Correct answer: Changed Block Tracking (CBT)
Changed Block Tracking (CBT) must be enabled on the source VM so Veeam can identify and replicate only the disk blocks that changed since the last replication cycle.
