Quick Answer
The answer is DynamoDB Global Tables, the correct choice for achieving multi-region active-active low latency in globally distributed applications. This feature replicates data across multiple AWS Regions automatically, allowing both reads and writes to occur at any replica with sub-second latency, ensuring a truly active-active architecture where every region can serve traffic independently. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of global database patterns versus caching or scaling mechanisms—a common trap is confusing Global Tables with DAX, which only accelerates reads via caching, or with DynamoDB Streams, which captures changes but does not enable multi-region writes. Remember the mnemonic: "Global Tables for Global Traffic" to distinguish it from local optimizations like DAX or Auto Scaling.
This SAP-C02 practice question tests your understanding of design for new solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Auto Scaling
Why wrong: Auto Scaling adjusts capacity, not replication.
DynamoDB Accelerator (DAX)
Why wrong: DAX is a caching layer, not multi-region replication.
DynamoDB Streams
Why wrong: Streams capture changes, not provide multi-region active-active.
Global Tables
Global Tables replicate data across regions for low-latency access.
Answer choices
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. Option B (DAX) is a caching layer, Option C (Auto Scaling) adjusts throughput, and Option D (Streams) captures changes.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
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 capacity, not replication.
DynamoDB Accelerator (DAX)
Why it's wrong here
DAX is a caching layer, not multi-region replication.
DynamoDB Streams
Why it's wrong here
Streams capture changes, not provide multi-region active-active.
Global Tables
Why this is correct
Global Tables replicate data across regions for low-latency access.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
