   A company has a documented RTO of 4 hours for its CRM application. The backup team performs a restore test every quarter, but the test only verifies that the backup files are readable. The last actual restore took 6 hours. What should the company do to ensure the RTO is achievable?

   • AIncrease the frequency of backups to reduce the amount of data to restore
   • BPerform a full application restore test that measures the time from backup initiation to application availability
   • CSwitch to a different backup vendor to get faster restore speeds
   • DDocument the RTO as 6 hours to match the observed restore time

   An e-commerce platform runs active-active in two cloud regions. The database is synchronously replicated between the regions. A regional disaster occurs, and the DNS failover redirects traffic to the healthy region. Which statement best describes the expected recovery outcome?

   • ARPO and RTO cannot be determined without knowing the backup retention policy
   • BRPO is measured in hours because replication is asynchronous by default
   • CRTO is high because the database must be restored from the last backup before traffic can be served
   • DRPO is near zero and RTO is minimal because the standby region already has current data and can serve traffic immediately

   A company experiences a ransomware attack that encrypts its primary file servers. The IT team restores the files from backups taken 12 hours ago. The company's RPO is 4 hours. What is the most significant issue with this recovery?

   • AThe RTO was not met because the restore took too long
   • BThe backups were not encrypted
   • CThe backups were stored in the same region as the primary data
   • DThe RPO was not met because 12 hours of data were lost

   A multinational e-commerce company runs its primary application in a single cloud region. Leadership mandates an RTO of 2 hours and an RPO of 15 minutes for the entire application. The current setup uses daily snapshots stored in the same region. The cloud provider offers a second region 500 miles away with synchronous replication and a third region 2,000 miles away with asynchronous replication. The application can run in either secondary region, but the 2,000-mile link has a replication lag of 5 minutes. Which DR design best meets both objectives?

   • AUse the 2,000-mile region with synchronous replication
   • BUse the 500-mile region with synchronous replication and automated failover
   • CUse daily snapshots replicated to the 500-mile region
   • DUse the 2,000-mile region with asynchronous replication and manual failover
