CSA Backup & Disaster Recovery 2

Question 1

What does RTO stand for in disaster recovery planning?

Accepted Answer

Recovery Time Objective

Answer

RTO (Recovery Time Objective) defines the maximum acceptable downtime before business operations must be restored after a disaster.

Question 2

Which backup strategy involves copying only the data that has changed since the last full backup?

Accepted Answer

Differential backup

Answer

A differential backup copies all data changed since the last full backup, making restoration faster than incremental since only the full and latest differential are needed.

Question 3

What is the primary purpose of a hot site in disaster recovery?

Accepted Answer

To provide a fully operational duplicate environment for immediate failover

Answer

A hot site is a fully equipped, continuously running duplicate facility that allows near-instant failover when the primary site goes down.

Question 4

A company performs a full backup every Sunday and incremental backups daily. If disaster strikes Thursday, which backups are needed to restore?

Accepted Answer

Sunday full + Monday, Tuesday, Wednesday, and Thursday incrementals

Answer

Incremental restores require the last full backup plus every incremental backup taken since, making the process longer but storage-efficient.

Question 5

What does RPO measure in a disaster recovery plan?

Accepted Answer

The maximum tolerable data loss measured in time

Answer

RPO (Recovery Point Objective) defines the maximum age of data that must be recovered, determining how frequently backups must occur.
