   A company performs a disaster recovery test by restoring its application from backups to a separate cloud environment. The test is successful, but the actual recovery time is 3 hours, exceeding the 2-hour RTO. The backup team finds that the restore process requires manual steps to configure networking and DNS. What should the company do to meet the RTO?

   • AIncrease the backup frequency to reduce the amount of data to restore
   • BDocument the manual steps and accept the 3-hour RTO
   • CAutomate the networking and DNS configuration as part of the recovery runbook
   • DUse a larger restore instance to speed up the restore process

   A company runs a critical application with an RTO of 1 hour and an RPO of 15 minutes. The application data is stored in a database that changes frequently. The backup team proposes a strategy of daily full backups plus transaction log backups every 15 minutes. The restore process requires applying the full backup and then all transaction logs. During a test, the restore takes 75 minutes. Which change would most directly reduce the restore time to meet the RTO?

   • AUse differential backups instead of transaction logs
   • BIncrease transaction log backup frequency to every 5 minutes
   • CTake a full backup every 6 hours instead of daily
   • DAccept the 75-minute restore time and update the RTO to 2 hours
