- A
The function's handler name is incorrect in the deployment package.
Why wrong: An incorrect handler causes an 'InvalidParameterValueException' when invoking, not during deployment.
- B
The Lambda function's IAM role is missing necessary permissions.
Why wrong: Missing permissions cause an 'AccessDeniedException', not 'ResourceConflictException'.
- C
The Lambda function's memory limit is set too low for the deployment package.
Why wrong: Memory limits affect execution, not deployment; deployment errors are about code upload conflicts.
- D
Another deployment is currently in progress for the same Lambda function.
AWS Lambda does not allow concurrent updates; a 'ResourceConflictException' indicates an ongoing update.
Question 1,420 of 1,616
Lambda ResourceConflictException — Deployment Conflict Error
This DVA-C02 practice question tests your understanding of deployment. 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 developer deploys a new version of an AWS Lambda function using the AWS CLI. The deployment fails with a 'ResourceConflictException' error. 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.

Correct answer & explanation
✓
Another deployment is currently in progress for the same Lambda function.
The 'ResourceConflictException' error in AWS Lambda occurs when an operation conflicts with another operation in progress. The most common cause is attempting to update the Lambda function's code while another deployment is already in progress (option D). Options A, B, and C lead to different errors: an incorrect handler name causes an 'InvalidParameterValueException', missing IAM permissions cause an 'AccessDeniedException', and a low memory limit does not cause a conflict but may result in performance issues or an error during invocation, not deployment.
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 function's handler name is incorrect in the deployment package.
Why it's wrong here
An incorrect handler causes an 'InvalidParameterValueException' when invoking, not during deployment.
- ✗
The Lambda function's IAM role is missing necessary permissions.
Why it's wrong here
Missing permissions cause an 'AccessDeniedException', not 'ResourceConflictException'.
- ✗
The Lambda function's memory limit is set too low for the deployment package.
Why it's wrong here
Memory limits affect execution, not deployment; deployment errors are about code upload conflicts.
- ✓
Another deployment is currently in progress for the same Lambda function.
Why this is correct
AWS Lambda does not allow concurrent updates; a 'ResourceConflictException' indicates an ongoing update.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

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.
