Answers
B.

C.
Increase the network bandwidth to the DR site.
Answers
C.
Increase the network bandwidth to the DR site.
D.
Implement real-time replication for the DR site.
Answers
D.
Implement real-time replication for the DR site.
Suggested answer: D

Explanation:

To meet the objective of ensuring minimal data loss (no more than 30 minutes of data) in case of a failover, real-time replication is the best solution. This technique involves continuously replicating data from the primary site to the disaster recovery (DR) site, minimizing data loss to the smallest possible timeframe (i.e., near real-time). Other options, such as content caching or nightly backups, do not address the requirement for minimal data loss effectively. Increasing bandwidth to the DR site may help with the recovery process but will not necessarily reduce the amount of lost data. CASP+ emphasizes the need for solutions like real-time replication to meet strict recovery time objectives (RTO) and recovery point objectives (RPO) in disaster recovery planning.
