SAP-C02 Design for New Solutions Practice Question
A company is designing a multi-region active-active application using Amazon DynamoDB. They need to ensure low-latency reads and writes globally. Which DynamoDB feature should they use?
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
✓
Global Tables
DynamoDB Global Tables provide a fully managed, multi-region, multi-active database for low-latency reads and writes globally. Option A (Auto Scaling) adjusts throughput but doesn't enable multi-region replication. Option B (DAX) is an in-memory cache that improves read latency but doesn't handle writes or multi-region. Option C (Streams) captures item-level changes but requires additional setup for cross-region replication. Option D (Global Tables) is the correct feature for active-active multi-region workloads.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Auto Scaling
Why it's wrong here
Auto Scaling adjusts read/write capacity automatically but does not provide multi-region replication or global low-latency.
- ✗
DynamoDB Accelerator (DAX)
Why it's wrong here
DynamoDB Accelerator (DAX) is an in-memory cache that improves read latency for a single region, but does not support multi-region writes.
- ✗
DynamoDB Streams
Why it's wrong here
DynamoDB Streams captures item-level changes in a table, which can be used for cross-region replication via Lambda, but it is not a native multi-region active-active solution.
- ✓
Global Tables
Why this is correct
Global Tables provides fully managed, multi-region, multi-active replication, enabling low-latency reads and writes across multiple regions.
