VMCE Veeam Components and Architecture 4 — Questions and Answers
Question 1: What is the purpose of the Veeam WAN Accelerator in a backup architecture?
- Increasing proxy task concurrency
- Deduplicating and compressing data for efficient transfer over slow WAN links (Correct answer)
- Providing failover for the Backup Server
- Encrypting backup data at rest
Correct answer: Deduplicating and compressing data for efficient transfer over slow WAN links
The Veeam WAN Accelerator uses global deduplication and compression to reduce data transferred over WAN links for backup copy and replication jobs.
Question 2: In Veeam's Scale-out Backup Repository, what does the 'Performance Tier' refer to?
- The fastest proxy servers in the environment
- The local high-performance extents used for primary backup writes (Correct answer)
- The WAN accelerator cache
- The SSD cache on the Backup Server
Correct answer: The local high-performance extents used for primary backup writes
The Performance Tier in a SOBR consists of local high-performance storage extents where backups are initially written.
Question 3: Which Veeam service handles the actual data movement on a managed server (proxy or repository) during backup operations?
- Veeam Backup Service
- Veeam Transport Service (Correct answer)
- Veeam Installer Service
- Veeam Broker Service
Correct answer: Veeam Transport Service
The Veeam Transport Service (also called the Data Mover) runs on managed servers and handles actual data reading, writing, and transfer.
Question 4: What happens to the Veeam Backup Proxy role when no dedicated proxy is configured in the environment?
- Backups fail until a proxy is configured
- The Backup Server itself acts as the default proxy (Correct answer)
- Veeam uses the vCenter Server as the proxy
- A proxy is automatically deployed to the first ESXi host
Correct answer: The Backup Server itself acts as the default proxy
If no dedicated proxy is configured, the Veeam Backup Server automatically assumes the backup proxy role.
Question 5: Which Veeam component is required on the service provider side to allow tenants to use Veeam Cloud Connect for DRaaS (replication)?
- Veeam Enterprise Manager
- Veeam Cloud Connect Replication Gateway (Correct answer)
- Veeam Hardware Plan
- Veeam vCloud Director Integration
Correct answer: Veeam Cloud Connect Replication Gateway
The Cloud Connect Replication Gateway on the service provider side facilitates VM replication from tenant sites to the provider's infrastructure.
Question 6: In the Veeam architecture, what is the role of the Veeam Broker Service?
- Manages communication between Veeam components and vSphere/Hyper-V infrastructure (Correct answer)
- Processes restore requests from end-users
- Handles license verification with Veeam servers
- Provides load balancing between multiple Backup Servers
Correct answer: Manages communication between Veeam components and vSphere/Hyper-V infrastructure
The Veeam Broker Service maintains persistent connections with hypervisor APIs (vSphere, Hyper-V) and caches infrastructure data for faster job execution.
Question 7: What is the minimum number of Veeam Backup Proxies required for a Veeam backup infrastructure to function?
- 0 — proxies are entirely optional
- 1 — the Backup Server acts as proxy if none are dedicated (Correct answer)
- 2 — for redundancy
- 3 — one per ESXi host
Correct answer: 1 — the Backup Server acts as proxy if none are dedicated
At minimum, one proxy is required — the Backup Server itself fulfills this role automatically if no dedicated proxies are added.
