GCP global infrastructure (regions, zones) - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a region in GCP?

A region is a specific geographic location where Google Cloud resources are hosted. Each region contains multiple zones.

beginner

What is a zone in GCP?

A zone is an isolated location within a region. Zones help distribute resources to improve availability and fault tolerance.

beginner

Why does GCP have multiple zones in a region?

Multiple zones allow you to spread resources so if one zone fails, others keep working. This improves reliability and uptime.

beginner

How does GCP's global infrastructure help with latency?

By having regions around the world, GCP lets you place resources close to your users, reducing delay and improving speed.

beginner

What is the difference between a region and a zone in GCP?

A region is a broad geographic area with multiple zones. A zone is a smaller isolated data center within that region.

What does a GCP zone represent?

A A country where GCP operates

B An isolated data center within a region

C A global network of data centers

D A virtual machine instance

Zones are isolated locations within a region, usually data centers, to improve fault tolerance.

Why should you deploy resources across multiple zones?

A To improve availability and fault tolerance

B To limit access to resources

C To increase latency

D To reduce costs

Using multiple zones helps keep services running if one zone has a problem.

Which of the following best describes a GCP region?

A A geographic area with multiple zones

B A network of virtual machines

C A single data center

D A storage bucket

Regions are geographic areas that contain multiple zones.

How does GCP's global infrastructure reduce latency?

A By increasing the number of virtual machines

B By using faster CPUs

C By placing resources closer to users in different regions

D By limiting user access

Placing resources near users reduces the time data travels, lowering latency.

If a zone goes down, what happens to resources in other zones of the same region?

A They get deleted

B They also go down

C They slow down

D They keep running normally

Zones are isolated, so failure in one zone does not affect others.

Explain the relationship between regions and zones in GCP and why this structure is important.

Think about how spreading resources helps keep services running.

Describe how GCP's global infrastructure design helps reduce latency for users worldwide.

Consider why having data centers in many places matters.
