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
