DBS-C01 Deployment and Migration Practice Question

A company is deploying a new application that requires a globally distributed database with low latency reads. They choose Amazon DynamoDB global tables. What is a key consideration for this deployment?

⚠ Common exam trap

Many exam-takers confuse asynchronous multi-master replication with synchronous replication, leading candidates to incorrectly assume that global tables provide strong consistency across regions or that writes are synchronous.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Each replica can serve reads and writes independently.

Amazon DynamoDB global tables use a multi-master, active-active replication model. This means each replica region can independently serve both reads and writes, with eventual consistency across regions. This design enables low-latency local reads and writes for globally distributed applications, as each region operates autonomously.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Writes are synchronously replicated to all regions.

    Why it's wrong here

    Replication is asynchronous, not synchronous.

  • Each replica can serve reads and writes independently.

    Why this is correct

    Global tables are multi-master; each region can handle both reads and writes.

  • The table class must be DynamoDB Standard-Infrequent Access.

    Why it's wrong here

    Table class can be Standard; IA is optional.

  • Global tables support strongly consistent reads from any region.

    Why it's wrong here

    Only eventual consistency is supported across regions.
