- A
Configure application to read from any Region using the DynamoDB endpoint.
Global Tables allow reads from any Region.
- B
Configure Time to Live (TTL) to automatically expire old data.
Why wrong: TTL is for automatic deletion, not replication.
- C
Enable DynamoDB Global Tables.
Global Tables provide multi-Region replication with eventual consistency.
- D
Enable DynamoDB Streams on the table.
Streams capture item-level changes, which are used by Global Tables to replicate data.
- E
Deploy DynamoDB Accelerator (DAX) in each Region.
Why wrong: DAX is a caching layer, not required for replication.
Question 1,302 of 1,786
DynamoDB Global Tables: Multi-Region Replication
This DEA-C01 practice question tests your understanding of data store management. 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 disaster recovery solution for Amazon DynamoDB. They need to ensure that data is replicated across Regions with minimal latency and that applications can read from any Region. Which THREE steps should be taken? (Choose THREE.)
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
✓
Configure application to read from any Region using the DynamoDB endpoint.
Option A is correct because DynamoDB Global Tables provide multi-Region, multi-master replication, allowing applications to read from any Region by simply pointing to the local DynamoDB endpoint. This ensures low-latency reads by serving data from the closest Region, and the replication is fully managed by DynamoDB.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse DAX (a single-Region cache) with a multi-Region replication solution, or mistakenly think TTL can be used for data synchronization, when in fact only Global Tables combined with Streams provide the required cross-Region replication and read capability.
Detailed technical explanation
How to think about this question
DynamoDB Global Tables leverage DynamoDB Streams to capture item-level changes in a source table and replicate them to replica tables in other Regions, providing eventual consistency with sub-second replication latency. Under the hood, each replica table is a fully independent table that accepts writes locally, and conflicts are resolved using a last-writer-wins (LWW) algorithm based on the timestamp of the update. In a real-world scenario, a global e-commerce platform can use Global Tables to serve product catalog reads from the nearest Region while allowing writes to any Region, ensuring high availability during a Regional outage.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
