SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 uses AWS CodeDeploy to deploy a web application to an Auto Scaling group. The deployment fails with the error 'The overall deployment failed because too many individual instances failed deployment, too few healthy instances are available for deployment, or some instances in your deployment group are experiencing problems.' The deployment group has a minimum of 2 healthy instances. The Auto Scaling group has 4 instances. What should the SysOps administrator check first?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the Auto Scaling group's health check type and ensure it is set to ELB.
The error indicates that the deployment could not maintain the minimum healthy instances. Checking the Auto Scaling group's health check configuration is the first step because if the health check type is not set to ELB, the instances might be marked healthy even if they are not receiving traffic. Option C is correct. Option A is wrong because the error message does not point to missing hooks. Option B is wrong because the error is about health, not about permissions. Option D is wrong because the deployment configuration is not the primary issue; the error message specifically mentions healthy instances.
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.
✗
Review the deployment configuration to ensure it allows enough time for deployment.
Why it's wrong here
The error is not about timeout; it is about healthy instance availability.
✗
Verify that the AppSpec file includes the correct hooks.
Why it's wrong here
Missing hooks would cause individual instance failures, but the error is about healthy instance count.
✓
Check the Auto Scaling group's health check type and ensure it is set to ELB.
Why this is correct
If the health check is not ELB, instances might be considered healthy even if they fail the deployment, leading to insufficient healthy instances.
Clue confirmation
The clue words "first", "minimum / minimize" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
Check the IAM role for CodeDeploy to ensure it has sufficient permissions.
Why it's wrong here
Insufficient permissions would typically cause a different error.
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.
