The answer is the AMI ID specified in the template does not exist in the region. This failure occurs because CloudFormation validates the Amazon Machine Image (AMI) ID against the current region’s available images during stack creation; if the ID is from another region or has been deprecated, the service returns an explicit “invalid AMI ID” error. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this scenario tests your ability to read error messages precisely—many candidates mistakenly blame instance type mismatches or IAM permissions, but the error text directly points to the AMI. A common trap is assuming all AMI IDs are global, when in fact each AMI is region-specific and must be copied or referenced correctly. Remember the mnemonic: “AMI IDs are regional, not universal—copy before you cross.”
SOA-C02 Deployment, Provisioning, and Automation Practice Question
This SOA-C02 practice question tests your understanding of deployment, provisioning, and automation. 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.
Network Topology
A CloudFormation stack creation failed. The administrator runs the command shown in the exhibit. What is the most likely reason for the failure?
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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The AMI ID specified in the template does not exist in the region
Option A is correct because the error explicitly states the AMI ID is invalid. Option B is wrong because the error mentions the AMI ID, not instance type. Option C is wrong because there is no indication of missing permissions. Option D is wrong because the error is about the AMI, not the region.
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.
✗
The IAM role for CloudFormation does not have permission to launch EC2 instances
Why it's wrong here
The error indicates an invalid AMI, not a permission issue.
✗
The stack is being created in a region that does not support the specified AMI
Why it's wrong here
That is essentially the same as option A, but option A is more precise.
✓
The AMI ID specified in the template does not exist in the region
Why this is correct
The error says the AMI ID is invalid.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
The instance type t2.micro is not supported in the target Availability Zone
Why it's wrong here
The error does not mention instance type.
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.
