A small business uses a rotating set of 12 backup tapes. Each week, a full backup is written to a tape, and the oldest tape is reused. The business recently discovered that a tape from three weeks ago was needed for a restore, but it had already been overwritten. What is the most likely cause?

The retention policy does not keep tapes long enough to cover the recovery window

The backup software failed to verify the tape before overwriting

The tapes were stored in an offsite location that was not accessible

The backup schedule was set to run more frequently than weekly

A company runs a virtualized environment with 50 VMs on a hypervisor cluster. They want to back up the VMs with minimal impact on production performance and the ability to restore individual files from a VM without restoring the entire VM. Which backup method is most appropriate?

Cloud backup by replicating each VM's VHDX file to object storage

Hypervisor-level backup using snapshots and changed-block tracking

Tape backup of the hypervisor cluster's storage volumes

Agent-based backup installed inside each VM

What is a primary advantage of a decentralized backup topology?

It reduces the risk of a single point of failure for backup management

It reduces storage costs by eliminating duplicate data

It simplifies management by centralizing all backup policies

It ensures that all backups are stored in a single, secure location

In a centralized backup topology, where are backup servers and storage typically located?

In the cloud, with no on-premises components

At a single, central location that manages backups for all systems

Distributed across multiple sites, each with its own backup server

At each client machine, with no central management

A company uses a 10-tape rotation with a full backup every Friday. They are required to retain backups for 6 months. The backup administrator notices that tapes are being overwritten before the 6-month retention period ends. Which solution best addresses this while minimizing new tape purchases?

Reduce the retention period to 10 weeks

Use a grandfather-father-son scheme with 12 monthly tapes

Increase the number of tapes in the rotation to 26

Switch to a daily full backup schedule
