VMCE Virtualization & Cloud Infrastructure Management 4 — Questions and Answers
Question 1: In Veeam Backup & Replication, what is the 'Backup Chain' and why does its format matter for restore speed?
- A linked sequence of full and incremental backup files affecting how far back restores must read (Correct answer)
- A cryptographic chain verifying backup file integrity
- A replication sequence between two Veeam servers
- A log of all backup job executions stored in the Veeam database
Correct answer: A linked sequence of full and incremental backup files affecting how far back restores must read
A backup chain consists of a full backup (.vbk) and subsequent incrementals (.vib); longer chains require reading more files during restore, impacting speed.
Question 2: What distinguishes 'Reverse Incremental' backup mode from 'Forward Incremental' in Veeam?
- Reverse incremental always creates a new full backup daily
- Reverse incremental keeps the most recent backup as a full file by rolling back older incrementals (Correct answer)
- Forward incremental stores data in reverse chronological order
- Reverse incremental uses CBT in reverse direction to detect unchanged blocks
Correct answer: Reverse incremental keeps the most recent backup as a full file by rolling back older incrementals
In reverse incremental mode, Veeam transforms the previous full backup into an older restore point while the newest restore point always remains a full .vbk file.
Question 3: When Veeam detects that a VM's CBT has become corrupted or unreliable, what fallback mechanism does it use?
- It skips the VM and logs a warning
- It performs a rescan using full block read to rebuild the incremental
- It automatically resets CBT and performs a new active full backup (Correct answer)
- It switches to agent-based backup mode
Correct answer: It automatically resets CBT and performs a new active full backup
When CBT is detected as unreliable, Veeam resets CBT on the VM and forces an active full backup to establish a new reliable baseline.
Question 4: In a Veeam replication job, what is 'Replica Seeding' used for?
- Pre-populating replica restore points using an existing local backup to minimize WAN transfer (Correct answer)
- Encrypting replica data before transmission
- Initializing CBT on the destination VM
- Creating the initial full backup at the source before replication begins
Correct answer: Pre-populating replica restore points using an existing local backup to minimize WAN transfer
Replica seeding allows administrators to use an existing backup at the destination site to seed the replica, drastically reducing initial WAN data transfer.
Question 5: What does Veeam's 'Application-Aware Processing' do for Microsoft SQL Server VMs?
- Truncates SQL transaction logs after successful backup to prevent log growth (Correct answer)
- Installs a permanent SQL agent on the VM
- Replaces VSS with a native SQL backup
- Compresses SQL data files before backup
Correct answer: Truncates SQL transaction logs after successful backup to prevent log growth
Application-aware processing uses VSS with SQL Server writer to ensure transactional consistency and can optionally truncate transaction logs post-backup.
Question 6: Which Veeam component is responsible for managing tape libraries and drives for archival backup jobs?
- Veeam Tape Server (Correct answer)
- Veeam WAN Accelerator
- Veeam Gateway Server
- Veeam Mount Server
Correct answer: Veeam Tape Server
The Veeam Tape Server is a dedicated role that manages physical tape libraries and drives for writing backup data to tape media.
Question 7: When configuring a Veeam backup job for VMs with large, frequently changing databases, which option reduces the backup window by skipping unchanged swap and page file blocks?
- Exclude deleted file blocks
- Exclude swap files and page files (Correct answer)
- Enable per-VM backup chains
- Use changed block tracking only
Correct answer: Exclude swap files and page files
Veeam can be configured to exclude swap and page files during backup since they don't contain persistent data, significantly reducing backup size and time.
