   A company uses a backup solution that takes VM snapshots and then copies the snapshot data to an off-site location. The backup window is 4 hours, and the RPO is 24 hours. The storage team reports that the snapshot files are growing rapidly, causing performance degradation on the production storage. What is the best way to mitigate this while maintaining the RPO?

   • ADisable snapshots and use agent-based backups.
   • BDelete the snapshots immediately after the backup copy completes.
   • CIncrease the backup frequency to reduce snapshot size.
   • DUse a separate storage array for snapshots.

   A DR administrator is evaluating backup and snapshot strategies for a VM that runs a critical application. The application has a 1-hour RPO and a 4-hour RTO. The administrator must choose between hourly snapshots and nightly backups with transaction log shipping. Which factor should most influence the decision?

   • AThe performance impact of taking snapshots on the production VM.
   • BThe complexity of managing transaction logs versus snapshots.
   • CThe cost of storage for snapshots versus backups.
   • DThe ability to recover to a specific point-in-time within the RPO.

   • BEncrypting the replication traffic
   • CStoring replication logs in plain text
   • DDisabling all firewalls at the recovery site

   An organization replicates a VM to a DR site using asynchronous replication with a 30-minute RPO. During a disaster, the primary site fails at 2:00 PM. The last successful replication was at 1:45 PM. The DR site activates the VM. What is the maximum potential data loss?

   • A45 minutes of data
   • B30 minutes of data
   • CNo data loss because the replication is asynchronous.
   • D15 minutes of data

   During a DR test, the administrator performs a failover of a VM to the DR site. The VM starts successfully, but the application fails to connect to its database, which is on another VM. What is the most likely cause?

   • AThe application's license is not valid at the DR site.
   • BThe VM's IP address changed after failover.
   • CThe VM's firewall is blocking the application's traffic.
   • DThe database VM was not failed over or is not reachable on the DR network.
