Mixed Deck — All VMCE Topics Flashcards

What happens to VMware CBT (Changed Block Tracking) data when a VM snapshot is deleted in vSphere?

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.

Which Veeam restore option allows a VM backup to be recovered to a different ESXi host or vCenter than where it was originally backed up?

Answer: Restore to a different location

The 'Restore to a different location' option in Veeam allows targeting a different ESXi host, cluster, datastore, or vCenter than the original source.

After a Failback operation completes in Veeam, what is the status of the replica VM at the DR site?

Answer: It is powered off and retained as a standby replica

After a successful failback commit, the DR replica VM is powered off and kept as a standby replica, ready for the next replication cycle from the recovered production site.

What Veeam capability allows you to failover multiple VMs simultaneously as a coordinated group?

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.

In a Veeam Failover Plan, what is the purpose of the 'Boot delay' setting between VM groups?

Answer: It sets a pause between powering on VM groups so dependent services have time to start before the next group boots

Boot delay between VM groups ensures that infrastructure services (like domain controllers or database servers) are fully started before dependent application VMs are powered on.

Which Veeam component is responsible for converting a backup file stored in a repository into a live VM for Instant Recovery?

Answer: vPower NFS Server

The vPower NFS Server publishes a virtual NFS datastore backed by the backup file, enabling a hypervisor to boot a VM directly from the repository without restoring to production storage.

What is the role of the WAN Accelerator in Veeam Backup & Replication and when should it be deployed?

Answer: It deduplicates and compresses backup data across WAN links to reduce bandwidth consumption for remote jobs

WAN Accelerators use global data deduplication caching at both source and target to dramatically reduce the data transferred over slow or expensive WAN connections.

Which Veeam feature prevents ransomware from deleting or modifying backup files by making them read-only at the OS level for a defined period?

Answer: Immutability flag (chattr +i) on Linux hardened repository

Veeam uses the Linux 'chattr +i' immutability flag on XFS volumes to make backup files read-only at the OS level for the configured immutability window.

When configuring a backup job targeting a scale-out backup repository, which setting determines which extent receives new backup files?

Answer: Performance tier placement policy (data locality or performance)

The SOBR placement policy (data locality or performance) controls how Veeam distributes backup files across extents.

Which Veeam ONE component is responsible for collecting performance data from vSphere environments?

Answer: Veeam ONE Monitor

Veeam ONE Monitor collects and displays real-time performance data from vSphere and Hyper-V environments.

Which Veeam feature enables recovery of individual application items (emails, calendar items) from Microsoft Exchange backups?

Answer: Veeam Explorer for Microsoft Exchange

Veeam Explorer for Microsoft Exchange provides granular item-level recovery of emails, folders, mailboxes, and calendar items directly from VM backups without a full Exchange restore.

What does Veeam's 'Application-Aware Processing' do for Microsoft SQL Server VMs?

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.

In a Hyper-V environment, what is the role of the Veeam Off-Host Backup Proxy?

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.

In Veeam's architecture, what is the purpose of a WAN Accelerator?

Answer: To deduplicate and compress backup traffic between sites, reducing bandwidth consumption

WAN Accelerators use global deduplication and caching to reduce the volume of data transferred between sites, making offsite backups and replications much faster.

In a Veeam Scale-out Backup Repository, what policy controls how new backup files are distributed across multiple extents?

Answer: Round-robin and least-used extent policies

SOBR uses a data locality policy (keeping all files for a VM on the same extent) or a performance policy (writing to the extent with the most free space or least load).

What is the maximum number of concurrent tasks a single Veeam Backup Proxy can handle by default, and what controls this setting?

Answer: The concurrent task limit is configurable per proxy (default 2), controlled in the Backup Proxy properties in the Veeam console

Each backup proxy has a configurable concurrent task limit (defaulting to 2) set in its properties, allowing administrators to tune performance based on available proxy resources.

When a Veeam hardened Linux repository is configured, which SSH authentication method is recommended over password authentication?

Answer: SSH public key authentication

SSH public key authentication is recommended because it eliminates password-based brute-force risks and is the standard for securing Linux server access.

A mission-critical database server has failed. The primary objective is to make the database available for users in the shortest possible time, even if performance is temporarily degraded. While the full restore operation will take several hours, application owners need access immediately. Which Veeam feature will achieve this goal?

Answer: Instant VM Recovery

Instant VM Recovery is designed for scenarios where minimizing Recovery Time Objective (RTO) is critical. It runs the VM directly from the backup file on the repository, making it available in minutes. While the VM is running in this state, a full restore can be performed in the background using Storage vMotion or Veeam's migration technology. Veeam Explorer is for granular restores, not bringing the whole server online. A Full VM Restore would not meet the immediate availability requirement.

What is the default data collection interval for Veeam ONE performance metrics from VMware vSphere?

Answer: 5 minutes

Veeam ONE collects performance metrics from VMware vSphere every 5 minutes by default.

What is the effect of enabling 'Replica re-IP' in a Veeam failover plan for a Windows VM?

Answer: Veeam automatically changes the replica VM's IP address to a DR-site address upon failover

Replica re-IP uses Veeam's guest OS scripting to modify the IP, subnet, gateway, and DNS settings inside the replica VM when it is powered on at the DR site, so it matches the DR network addressing scheme.
