Disaster recovery strategies in Azure - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the main goal of disaster recovery in cloud infrastructure?

The main goal is to restore IT systems and data quickly after a failure or disaster to minimize downtime and data loss.

intermediate

Explain the difference between Recovery Point Objective (RPO) and Recovery Time Objective (RTO).

RPO is the maximum acceptable amount of data loss measured in time (how far back data can be recovered). RTO is the maximum acceptable time to restore systems after a disaster.

What is Azure Site Recovery and how does it help in disaster recovery?

Azure Site Recovery replicates workloads running on physical and virtual machines to a secondary location, enabling quick failover and recovery during disasters.

intermediate

Name two common disaster recovery strategies used in cloud environments.

1. Backup and Restore: Regular backups stored safely to restore data. 2. Pilot Light: Minimal critical systems running in a secondary region ready to scale up.

beginner

Why is testing disaster recovery plans regularly important?

Regular testing ensures the plan works as expected, identifies gaps, and prepares teams to respond effectively during real disasters.

What does RTO stand for in disaster recovery?

A Recovery Time Objective

B Recovery Transfer Operation

C Restore Time Option

D Remote Transfer Objective

RTO means Recovery Time Objective, the max time allowed to restore systems after a disaster.

Which Azure service helps replicate workloads for disaster recovery?

A Azure Site Recovery

B Azure Backup

C Azure Monitor

D Azure DevOps

Azure Site Recovery replicates workloads to a secondary location for disaster recovery.

What is the main purpose of a Pilot Light disaster recovery strategy?

A Store backups in cold storage

B Run full production systems in multiple regions simultaneously

C Run minimal critical systems in a secondary region ready to scale

D Only backup data without system replication

Pilot Light keeps minimal critical systems running in a secondary region to quickly scale up after disaster.

Which of the following is NOT a disaster recovery best practice?

A Regularly test the recovery plan

B Ignore RPO and RTO requirements

C Automate failover processes

D Keep backups offsite

Ignoring RPO and RTO is bad practice; they guide recovery goals.

What does RPO measure?

A Remote process operation

B Maximum downtime allowed

C Recovery process order

D Maximum data loss time allowed

RPO measures the maximum acceptable amount of data loss in time.
