SOA-C02 Reliability and Business Continuity Practice Question

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 runs a web application on EC2 instances in an Auto Scaling group. The application uses an Amazon RDS Multi-AZ DB instance. The SysOps administrator notices that during a recent failover test, the application became unresponsive for several minutes. The administrator wants to improve the application's resilience during failover. Which three actions should the administrator take? (Choose THREE.)

A
Configure the Application Load Balancer health checks to have a low threshold (e.g., 2 consecutive failures) and a short interval (e.g., 5 seconds).
Fast health checks allow the ALB to quickly take failing instances out of service, reducing user impact.
B
Implement retry logic in the application to handle transient database connection failures.
Retry logic allows the application to recover from temporary failures during failover.
C
Change the RDS DB instance to use asynchronous replication instead of synchronous replication.
Why wrong: Asynchronous replication could lead to data loss during failover. Multi-AZ already uses synchronous replication.
D
Increase the EC2 instance size to handle more connections during failover.
Why wrong: Instance size does not affect database failover time; it only increases compute capacity.
E
Configure an Amazon RDS Proxy in front of the RDS database to pool and share database connections.
RDS Proxy handles failover transparently and reduces connection disruption.

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 the Application Load Balancer health checks to have a low threshold (e.g., 2 consecutive failures) and a short interval (e.g., 5 seconds).

Options A, B, and D are correct. Using an RDS proxy (A) manages connections and reduces failover time. Retry logic (B) allows the application to reconnect after failover. Health checks with low thresholds (D) help the load balancer quickly detect and route away from unhealthy instances. Option C is wrong because synchronous replication is already used in Multi-AZ; asynchronous replication would reduce durability. Option E is wrong because increasing instance size does not reduce failover time.

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

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.

What to study next

Got this wrong? Here's your next step.

Identify which SOA-C02 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
