GCP Associate Cloud Engineer Practice Question

Your company is launching a customer portal that will store user-uploaded photos in Cloud Storage. Compliance rules require the objects to remain inside the United States, and the operations team wants the data to be automatically stored in at least two geographically separate US regions without having to configure or manage replication or fail-over themselves. Which Cloud Storage location choice best satisfies these requirements while keeping the deployment as simple as possible?

Create the bucket in the single-region location "us-central1".
Create the bucket in the Cloud Storage multi-region location "us".
Create the bucket in the dual-region location "us-central1+us-east1".
Create separate buckets in "us-central1" and "us-east1" and configure Cloud Storage Transfer Service with Turbo Replication between them.

Answer Description

A Cloud Storage multi-region such as "us" automatically and transparently stores every object in at least two separate US regions that are a minimum of 100 miles apart. This meets the requirement that data stay within the United States and provides built-in regional redundancy without any additional replication configuration.

A single-region location like "us-central1" keeps data in one region only, so it fails the redundancy requirement. A dual-region such as "us-central1+us-east1" does replicate across two regions, but it requires you to specify and manage the pair; a multi-region removes that operational overhead. Creating two separate single-region buckets and setting up Transfer Service with Turbo Replication adds even more management complexity and does not provide the seamless, built-in redundancy requested.
