SOA-C02 Reliability and Business Continuity Practice Question
This SOA-C02 practice question tests your understanding of reliability and business continuity. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Stop an EC2 instance.
The IAM policy grants the ec2:StopInstances action, which allows the user to stop EC2 instances. The condition restricts the action to instances with a specific tag, but the core permission is for stopping instances, making option C correct.
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.
✗
Start an EC2 instance.
Why it's wrong here
The user can start instances, but the question asks which action is allowed; all listed actions except terminate are allowed.
✗
Describe EC2 instances.
Why it's wrong here
Describe* is allowed, but the question asks for a specific action; stop is also allowed.
✓
Stop an EC2 instance.
Why this is correct
StopInstances is explicitly allowed and not denied.

✗
Terminate an EC2 instance.
Why it's wrong here
TerminateInstances is explicitly denied.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the ec2:StopInstances action with ec2:TerminateInstances, as both involve changing instance state, but only StopInstances is granted in the policy.
Detailed technical explanation
How to think about this question
The ec2:StopInstances action is part of the EC2 API and is used to stop a running instance, transitioning it to a stopped state. The condition in the policy uses the ec2:ResourceTag key to restrict the action to instances with a specific tag, demonstrating how IAM policies can enforce resource-level permissions. This is a common pattern for implementing least-privilege access in AWS environments.
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.
TExam Day Tips
→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.
