This SAP-C02 practice question tests your understanding of design for new solutions. 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 designing a new application that will be deployed on AWS. The application requires a relational database with automatic failover and high availability within a single AWS region. Which database deployment option meets these requirements?
Amazon RDS Single-AZ deployment
Why wrong: Single-AZ does not provide automatic failover.
Amazon RDS with Read Replicas
Why wrong: Read Replicas are for read scaling, not automatic failover.
Amazon RDS Multi-AZ deployment
Multi-AZ provides automatic failover and high availability within a region.
Amazon RDS cross-region replication
Why wrong: Cross-region replication is for disaster recovery, not primary failover within a region.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon RDS Multi-AZ deployment
Option C is correct because RDS Multi-AZ provides automatic failover and high availability within a region. Option A is wrong because Single-AZ does not provide failover. Option B is wrong because Read Replicas are for read scaling, not failover. Option D is wrong because cross-region replication is for disaster recovery, not primary failover.
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.
Amazon RDS Single-AZ deployment
Why it's wrong here
Single-AZ does not provide automatic failover.
Amazon RDS with Read Replicas
Why it's wrong here
Read Replicas are for read scaling, not automatic failover.
Amazon RDS Multi-AZ deployment
Why this is correct
Multi-AZ provides automatic failover and high availability within a region.

Amazon RDS cross-region replication
Why it's wrong here
Cross-region replication is for disaster recovery, not primary failover within a region.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
