CompTIA Server+ SK0-005 Practice Question

A company is replacing its off-site tape rotation with a cloud backup service. Management expects that a full restore of a 4 TB file server must still meet the existing three-hour recovery time objective (RTO) when the data is brought back to the on-premises datacenter. Which characteristic of the cloud solution will have the greatest direct impact on whether the RTO can be met during a large-scale restore?

  • The provider's advertised object-storage durability rating (for example, 11 nines)

  • The use of multi-region replication that stores the backups in three availability zones

  • The maximum sustained download bandwidth available between the cloud provider's region and the datacenter

  • Whether the backup objects are encrypted at rest with AES-256 keys managed by the provider
