Disaster recovery strategies in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

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

To restore normal operations quickly after a failure or disaster, minimizing downtime and data loss.

beginner

Explain the difference between RTO and RPO.

RTO (Recovery Time Objective) is the maximum time allowed to restore services after a disaster. RPO (Recovery Point Objective) is the maximum acceptable amount of data loss measured in time.

What is a multi-region deployment in GCP disaster recovery?

It means running your applications and data in multiple geographic regions to ensure availability if one region fails.

beginner

How do automated backups help in disaster recovery?

Automated backups regularly save copies of data so you can restore it quickly after data loss or corruption.

beginner

What is the purpose of a disaster recovery plan?

To have a clear, tested process to recover systems and data after a disaster, reducing confusion and downtime.

Which of the following best describes Recovery Point Objective (RPO)?

A Maximum time to restore service after failure

B Maximum acceptable data loss measured in time

C Total downtime allowed per year

D Amount of backup storage used

RPO defines how much data loss is acceptable, measured as time before the disaster.

What is a key benefit of multi-region deployment in GCP?

A Higher availability during regional failures

B Lower cost for storage

C Faster local network speeds

D Simpler billing

Multi-region deployment helps keep services running if one region goes down.

Which GCP service is commonly used for automated backups of databases?

A Cloud Storage

B Cloud Functions

C Cloud SQL automated backups

D Cloud Pub/Sub

Cloud SQL provides automated backups to protect database data.

What does Recovery Time Objective (RTO) measure?

A Time to complete a backup

B Time to detect a disaster

C Time between backups

D Time to restore service after disaster

RTO is the target time to get systems back online after a failure.

Why is testing a disaster recovery plan important?

A To ensure the plan works and staff know their roles

B To speed up backups

C To increase data storage

D To reduce cloud costs

Testing confirms the plan is effective and everyone understands their tasks.

Describe the key components of a disaster recovery strategy in GCP.

Think about how to minimize downtime and data loss using GCP features.

Explain how automated backups and multi-region deployment work together to improve disaster recovery.

Consider data safety and service availability.
