SOA-C02 Networking and Content Delivery Practice Question

This SOA-C02 practice question tests your understanding of networking and content delivery. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

Network Topology

Refer to the exhibit. A SysOps Administrator runs the above command and sees that an EC2 instance is unhealthy. The health check is configured to check the HTTP endpoint '/health' on port 80. The instance's security group allows inbound HTTP traffic from the ALB's security group. What is the MOST likely cause?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Network Topology

A
The instance is not associated with the target group.
Why wrong: Incorrect. The instance is associated with the target group; otherwise it would not be listed as unhealthy.
B
The application on the instance is not configured to respond to the '/health' path.
Correct. The health check endpoint '/health' is not properly handled by the application, causing the health check to fail.
C
The target group is configured to use port 8080 instead of port 80.
Why wrong: Incorrect. The target group is configured to use port 80, not port 8080.
D
The security group on the instance does not allow inbound traffic from the ALB.
Why wrong: Incorrect. The security group on the instance allows inbound HTTP traffic from the ALB's security group, so this is not the cause of the health check failure.

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

✓

The application on the instance is not configured to respond to the '/health' path.

Option B is correct because the health check path is '/health', but the application on the instance might not have that endpoint configured, causing the health check to fail. Option A is incorrect because the instance is associated with the target group; otherwise it would not appear in the health check results. Option C is incorrect because the target group is configured to use port 80, as stated in the scenario. Option D is incorrect because the security group on the instance does allow inbound HTTP traffic from the ALB's security group, as stated in the scenario.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
