Multi-region architecture patterns in GCP - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a multi-region architecture in cloud computing?

A multi-region architecture means using cloud resources in more than one geographic area to improve availability, reduce latency, and increase fault tolerance.

beginner

Name one benefit of using multi-region architecture.

One benefit is higher availability because if one region fails, another can take over, keeping the service running.

What is active-active multi-region architecture?

Active-active means running your application in multiple regions at the same time, sharing the load and providing instant failover.

intermediate

How does active-passive multi-region architecture work?

Active-passive runs the application in one main region (active) and keeps a backup region (passive) ready to take over if the main one fails.

advanced

What is a common challenge when using multi-region architectures?

Keeping data consistent across regions can be hard because data changes in one place must be copied quickly and correctly to others.

What is the main goal of multi-region architecture?

A Improve availability and reduce latency

B Save money by using only one region

C Make the application slower

D Avoid using cloud services

Multi-region architecture improves availability and reduces latency by using multiple geographic locations.

In active-active multi-region, how are regions used?

A Multiple regions run the application simultaneously

B Regions are never used

C Only one region is active at a time

D Regions are used only for backups

Active-active means multiple regions run the application at the same time, sharing the load.

Which is a key challenge in multi-region setups?

A Making the app single-region only

B Finding enough cloud providers

C Data consistency across regions

D Avoiding backups

Keeping data consistent across regions is a common challenge in multi-region architectures.

What does active-passive multi-region mean?

A Both regions are active and share traffic

B One region is active, the other is standby

C No regions are active

D Regions are used randomly

Active-passive means one region handles traffic while the other waits to take over if needed.

Why might you choose multi-region architecture?

A To increase downtime

B To avoid backups

C To reduce security

D To improve fault tolerance and user experience

Multi-region architecture improves fault tolerance and user experience by reducing downtime and latency.

Explain the difference between active-active and active-passive multi-region architectures.

Think about how many regions handle traffic at the same time.

Describe one major challenge when designing multi-region cloud architectures and how it affects the system.

Consider what happens when data changes in one region.
