The correct choice is to deploy Amazon Aurora Global Database with a primary Region and read replicas in secondary Regions. This configuration meets the requirement for low-latency cross-region reads because Aurora Global Database uses dedicated, high-throughput network infrastructure to replicate data from the primary to secondary Regions with typical latency under one second, while read replicas in those secondary Regions serve local read traffic with minimal delay. Since the application is read-heavy and tolerates eventual consistency, this asynchronous replication model is ideal—it avoids the write latency penalty of synchronous replication across continents. On the AWS Certified Database Specialty DBS-C01 exam, this scenario tests your ability to distinguish between global read scaling solutions and single-Region high-availability options; a common trap is choosing RDS Multi-AZ, which only protects within one Region, or DynamoDB Global Tables, which is NoSQL. Remember the tip: “Global DB for global reads, Multi-AZ for local resilience.”
DBS-C01 Deployment and Migration Practice Question
This DBS-C01 practice question tests your understanding of deployment and migration. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 deploying a new application that requires low-latency reads from a relational database across multiple AWS Regions. The application is read-heavy and can tolerate eventual consistency. Which deployment option meets these requirements?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Deploy Amazon Aurora Global Database with a primary Region and read replicas in secondary Regions.
Option D (Aurora Global Database with read replicas in secondary Regions) is correct because it provides low-latency reads and eventual consistency. Option A (Single RDS instance with cross-Region read replicas) is possible but read replicas are asynchronous and may have more lag. Option B (DynamoDB Global Tables) is NoSQL. Option C (RDS Multi-AZ) is within a single region.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Deploy Amazon RDS for PostgreSQL with Multi-AZ and read replicas in the same Region.
Why it's wrong here
Multi-AZ is within a region; does not provide cross-Region low-latency reads.
✗
Deploy a single Amazon RDS for MySQL instance with cross-Region read replicas.
Why it's wrong here
Cross-Region read replicas provide eventual consistency but may have higher latency than Aurora Global Database.
✓
Deploy Amazon Aurora Global Database with a primary Region and read replicas in secondary Regions.
Why this is correct
Aurora Global Database provides low-latency reads in secondary Regions with eventual consistency.

✗
Deploy Amazon DynamoDB Global Tables in multiple Regions.
Why it's wrong here
DynamoDB is NoSQL, not relational.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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
How to think about this question
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.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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.

Variation 1. A company is deploying a new application that requires a relational database with automatic failover and cross-Region disaster recovery. The application is read-heavy and expects up to 10 GB of data. Which combination of AWS services should be used?
medium
A.Amazon RDS for MySQL with Multi-AZ and a read replica in another Region
B.Amazon S3 with AWS Glue and Amazon Athena
✓ C.Amazon Aurora with Multi-AZ and an Aurora global database
D.Amazon DynamoDB with global tables
Why C: Aurora with Multi-AZ and cross-Region replica provides high availability and DR. Option A is incorrect because RDS Multi-AZ does not provide cross-Region DR. Option C is incorrect because S3 and Athena are not relational databases. Option D is incorrect because DynamoDB global tables are for NoSQL.
