The answer is that the DynamoDB table specified in the Lambda function does not exist. This is the most likely cause because the AWS SDK throws a ResourceNotFoundException specifically when the requested table name is not found in the account or region, meaning the table has either been deleted or was never created with that exact name. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your ability to differentiate between common DynamoDB error codes, as many candidates mistakenly assume permission issues or throttling are the root cause. A common trap is confusing ResourceNotFoundException with AccessDeniedException, but insufficient permissions always result in a 403 error, not a 404. For a quick memory tip, remember that "Resource" in the error name points to the table resource itself being missing, not your access to it.
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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.

Refer to the exhibit. An AWS Lambda function logs the error above. The function uses the AWS SDK to call an Amazon DynamoDB table. What is the MOST likely cause?

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.

A
The Lambda function timed out while waiting for a response.
Why wrong: Timeout would cause a different error, not ResourceNotFoundException.
B
The DynamoDB table specified in the function does not exist.
ResourceNotFoundException means the resource is not found.
C
The Lambda function does not have permission to access DynamoDB.
Why wrong: Insufficient permissions cause AccessDeniedException, not ResourceNotFoundException.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The DynamoDB table specified in the function does not exist.
Option B is correct. ResourceNotFoundException indicates the DynamoDB table does not exist or has been deleted. Option A is wrong because insufficient permissions cause AccessDeniedException. Option C is wrong because throttling causes ProvisionedThroughputExceededException. Option D is wrong because a different error would occur if the function timed out.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
