GCP Associate Cloud Engineer Practice Question 44: Dual Region Bucket Location

Cloud Storagemedium

Compliance requires a bucket's data to be stored in exactly two named regions, europe-west1 and europe-west4, and the data must remain available if one of those regions has an outage, with no changes to the application when this happens.

Which bucket location should you choose?

Select one answer
Show answer and explanation

Answer:

  • B. A dual-region bucket configured with europe-west1 and europe-west4

A dual-region bucket stores data redundantly in the two specific regions you choose and is served under one bucket name. If one region is unavailable, requests are served from the other with no application change.

Option A uses the EU multi-region, where Google decides which locations within the EU hold the data, so you cannot guarantee that only those two regions are used. Option C keeps two separate copies with a custom job that adds work, lag, and a second bucket name to manage. Option D does not protect against a regional outage, because versions live in the same region.
