   A company stores backups in a cloud bucket and uses a backup automation tool. The security team requires that backup data be encrypted at rest and that only the backup service account can write to the bucket, while recovery engineers can read from it. Which configuration best meets these requirements?

   • AEnable default encryption on the bucket and assign write permission to the backup service account and read permission to the recovery engineers
   • BUse client-side encryption and store the keys in the same bucket
   • CDisable encryption to simplify access and assign both write and read permissions to all users
   • DEnable encryption but make the bucket public for easy access

   A global logistics company runs its tracking system in a primary cloud region. The system must be available with an RTO of 30 minutes and an RPO of 5 minutes. The company is considering two DR options: Option 1 uses a warm standby in a nearby region with continuous data replication; Option 2 uses a cold standby in a distant region with hourly backups. Which option should the company choose and why?

   • AOption 2, because cold standby can be activated within 30 minutes
   • BOption 1, because it is cheaper than Option 2
   • COption 2, because hourly backups meet the RPO of 5 minutes
   • DOption 1, because warm standby with continuous replication meets both the RTO and RPO
