VMCE Virtualization & Cloud Infrastructure Management 2 — Questions and Answers
Question 1: When backing up VMware vSphere VMs with Veeam, which transport mode reads data directly from the ESXi host's storage without going through the network?
- Network mode
- Direct SAN access (Correct answer)
- Hot-add (virtual appliance)
- NBD SSL
Correct answer: Direct SAN access
Direct SAN access transport mode allows the Veeam proxy to read VM data directly from the shared SAN storage, bypassing the ESXi host network.
Question 2: In a Hyper-V environment, what is the role of the Veeam Off-Host Backup Proxy?
- It runs inside the production VM to capture changed blocks
- It offloads backup processing from the Hyper-V host to a separate server (Correct answer)
- It acts as a repository for storing backup files
- It manages VSS coordination exclusively
Correct answer: It offloads backup processing from the Hyper-V host to a separate server
The off-host backup proxy offloads backup processing to a dedicated server, reducing the CPU and I/O load on the production Hyper-V host.
Question 3: What vSphere feature does Veeam leverage to create crash-consistent VM snapshots without quiescing the guest OS?
- vStorage APIs for Data Protection (VADP) (Correct answer)
- vSphere High Availability
- Distributed Resource Scheduler
- vSphere Fault Tolerance
Correct answer: vStorage APIs for Data Protection (VADP)
Veeam uses VMware's VADP framework to interact with the ESXi snapshot subsystem and read VM disk data during backup.
Question 4: When configuring Veeam to back up Nutanix AHV VMs, which component must be deployed on the Nutanix cluster?
- Veeam Backup & Replication server
- Veeam Backup for Nutanix AHV proxy appliance (Correct answer)
- Veeam Universal Storage API plugin
- Veeam Agent for Linux
Correct answer: Veeam Backup for Nutanix AHV proxy appliance
Veeam deploys a purpose-built proxy virtual appliance on the Nutanix AHV cluster to handle snapshot creation and data mover functions.
Question 5: Which Veeam capability allows administrators to restore individual guest OS files from a VM backup without performing a full VM restore?
- Instant VM Recovery
- Guest file system browsing (FLR) (Correct answer)
- Staged restore
- Secure Restore
Correct answer: Guest file system browsing (FLR)
File-level restore (FLR) mounts the backup and allows browsing the guest file system to restore individual files or folders.
Question 6: In Veeam's Scale-out Backup Repository (SOBR), what is the purpose of the 'Performance Tier'?
- Long-term archival to object storage
- Fast initial backup landing zone using high-performance extents (Correct answer)
- Deduplication appliance integration
- Tape rotation management
Correct answer: Fast initial backup landing zone using high-performance extents
The Performance Tier consists of high-performance extents that serve as the landing zone for new backups before optional tiering to Capacity Tier.
Question 7: What happens to VMware CBT (Changed Block Tracking) data when a VM snapshot is deleted in vSphere?
- CBT data is permanently lost and must be reset
- CBT continues to track changes correctly after snapshot consolidation (Correct answer)
- CBT is disabled automatically until the next full backup
- CBT resets only if more than 3 snapshots existed
Correct answer: CBT continues to track changes correctly after snapshot consolidation
Deleting a snapshot triggers consolidation, but VMware CBT continues tracking changed blocks correctly from that point forward.
