   A media company stores large video files that are rarely modified after creation. The current backup strategy is a nightly full backup, which takes 8 hours and consumes significant storage. Management wants to reduce storage consumption without increasing the RPO beyond 24 hours or the RTO beyond 12 hours. Which backup strategy best meets these requirements?

   • APerform a full backup only once a month and rely on incremental backups daily.
   • BUse a differential backup every night without any full backup.
   • CKeep the nightly full backup but compress the backup files.
   • DSwitch to a weekly full backup with daily incremental backups.

   A hospital's electronic health record system has an RPO of 15 minutes and an RTO of 1 hour. The system is currently backed up nightly, and the restore time is 3 hours. The hospital is considering implementing synchronous replication to a secondary data center. What is the most important trade-off to evaluate before choosing synchronous replication?

   • ASynchronous replication requires more storage capacity than nightly backups.
   • BSynchronous replication eliminates the need for any backup testing.
   • CSynchronous replication guarantees zero data loss in all failure scenarios.
   • DSynchronous replication may add latency to clinical workflows, affecting system performance.

   Why is regular testing of data recovery procedures important?

   • ATo eliminate the risk of data loss entirely
   • BTo ensure that backups are restorable and recovery steps work as expected
   • CTo reduce the need for backups
   • DTo satisfy regulatory requirements only

   A financial services firm must recover its trading database with a 5-minute RPO and a 30-minute RTO. The database is 2 TB and changes heavily during market hours. The team is comparing synchronous replication to a warm standby versus nightly full backups plus transaction log shipping. Which consideration is most important when choosing between these two approaches?

   • ASynchronous replication adds latency to every transaction, which may be unacceptable for the trading application's performance requirements.
   • BA warm standby requires more administrative effort to keep the standby schema synchronized with application changes.
   • CNightly full backups require more storage capacity than synchronous replication because they store multiple full copies.
   • DTransaction log shipping can meet the 5-minute RPO only if the logs are shipped and applied every few minutes, which is operationally complex.
