VMCE Backup Infrastructure and Repositories 5 — Questions and Answers
Question 1: What is the primary function of the Veeam Backup & Replication configuration database?
- Stores actual backup data files
- Stores infrastructure settings, job configurations, and session history (Correct answer)
- Caches deduplication metadata
- Indexes guest file system content
Correct answer: Stores infrastructure settings, job configurations, and session history
The configuration database (Microsoft SQL Server or PostgreSQL) stores all Veeam settings, job definitions, credentials, and session history.
Question 2: Which Veeam component must be deployed to enable WAN-optimized replication to a remote site?
- Backup Proxy
- WAN Accelerator (Correct answer)
- Gateway Server
- Mount Server
Correct answer: WAN Accelerator
WAN Accelerators must be deployed on both source and target sites to deduplicate and compress replication traffic across slow WAN links.
Question 3: In Veeam, what is a 'backup chain' and how does a forward incremental chain differ from a reverse incremental chain?
- Both store full backups daily; they differ only in naming
- Forward incremental keeps a full backup at the start; reverse incremental keeps the most recent full backup current (Correct answer)
- Reverse incremental requires more storage than forward incremental
- Forward incremental stores incrementals before the full; reverse stores them after
Correct answer: Forward incremental keeps a full backup at the start; reverse incremental keeps the most recent full backup current
Forward incremental starts with a full backup and appends incrementals; reverse incremental constantly updates the full backup, keeping it current with the latest data.
Question 4: Which Veeam setting controls how many days backup files are retained before they are automatically deleted?
- Backup Copy Interval
- Retention Policy (restore points) (Correct answer)
- GFS Retention
- Archive Tier Offload Policy
Correct answer: Retention Policy (restore points)
The Retention Policy setting defines how many restore points (or days) Veeam keeps before automatically removing older backup files.
Question 5: What is the recommended architecture for a Veeam deployment protecting more than 500 VMs to ensure scalability?
- Single backup server with a large repository
- Distributed deployment with multiple proxies and repositories (Correct answer)
- All-in-one appliance with embedded SQL
- Single proxy with multiple backup servers
Correct answer: Distributed deployment with multiple proxies and repositories
For large environments, Veeam recommends a distributed architecture with multiple backup proxies and repositories to parallelize workload and eliminate bottlenecks.
Question 6: Which Veeam repository option allows block-level deduplication and compression to be performed on the backup server before data is written to the repository?
- Source-side deduplication (Correct answer)
- Target-side deduplication
- Inline deduplication
- Repository-side compression
Correct answer: Source-side deduplication
Source-side deduplication processes and deduplicates data on the backup proxy/server before transmitting it to the repository, reducing network traffic.
Question 7: When a Veeam backup repository is added as a 'gateway server,' what primary function does it serve?
- Acts as a proxy for SMB/NFS shares that Veeam cannot directly access (Correct answer)
- Provides WAN acceleration for remote backups
- Hosts the Veeam Backup & Replication console
- Manages job scheduling for distributed deployments
Correct answer: Acts as a proxy for SMB/NFS shares that Veeam cannot directly access
A gateway server acts as an intermediary that allows Veeam to write data to SMB/NFS shares or other storage that requires a Windows agent to manage the connection.
