This SOA-C02 practice question tests your understanding of reliability and business continuity. 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 has a production RDS for PostgreSQL instance with Multi-AZ enabled. During a recent failover test, the application experienced a 5-minute downtime. The company requires that failover be completed within 2 minutes. Which action should be taken to meet this requirement?
Migrate the database to Amazon Aurora with Multi-AZ.
Why wrong: Overkill; RDS Proxy is sufficient.
Enable automated backups with a short retention period.
Why wrong: Backups do not impact failover time.
Increase the DB instance class to a larger size.
Why wrong: Instance size does not affect failover time.
Configure an RDS Proxy in front of the database.
RDS Proxy pools connections and reduces failover time.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Configure an RDS Proxy in front of the database.
Option C is correct because RDS Proxy reduces failover time by pooling database connections and maintaining them during failover. Option A is wrong because increasing instance size does not directly reduce failover time. Option B is wrong because enabling automatic backups does not affect failover speed. Option D is wrong because switching to Aurora may help but is a larger architectural change; RDS Proxy is a simpler solution for RDS.
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.

Increase the DB instance class to a larger size.
Why it's wrong here
Instance size does not affect failover time.
Configure an RDS Proxy in front of the database.
Why this is correct
RDS Proxy pools connections and reduces failover time.

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.
