- A
aws lambda list-layer-versions --layer-name my-layer
Why wrong: Lists versions of a specific layer, not attached to a function.
- B
aws lambda get-function --function-name my-function
Why wrong: Returns code and configuration but layers not included by default.
- C
aws lambda get-function-configuration --function-name my-function
Returns configuration including attached layers.
- D
aws lambda list-layers --function-name my-function
Why wrong: Lists all layers in the account, not attached layers.
Question 875 of 1,616
How to List Layers Attached to a Lambda Function Using AWS CLI
This DVA-C02 practice question tests your understanding of development with aws services. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 is deploying a new version of an AWS Lambda function. The deployment failed because the new function code references a layer that is not available. Which AWS CLI command can be used to list all layers associated with the function?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
aws lambda get-function-configuration --function-name my-function
The `aws lambda get-function-configuration` command returns the configuration details of a Lambda function, including a list of layer ARNs (Amazon Resource Names) associated with the function. This allows the developer to verify which layers are attached and identify any missing or incorrect layer references that caused the deployment failure.
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.
- ✗
aws lambda list-layer-versions --layer-name my-layer
Why it's wrong here
Lists versions of a specific layer, not attached to a function.
- ✗
aws lambda get-function --function-name my-function
Why it's wrong here
Returns code and configuration but layers not included by default.
- ✓
aws lambda get-function-configuration --function-name my-function
Why this is correct
Returns configuration including attached layers.

Read the scenario before looking for a memorised answer.
- ✗
aws lambda list-layers --function-name my-function
Why it's wrong here
Lists all layers in the account, not attached layers.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse commands that list all layers in an account (like `list-layers`) or list versions of a specific layer (like `list-layer-versions`) with the command that retrieves the layers attached to a specific function, which is `get-function-configuration`.
Detailed technical explanation
How to think about this question
The `get-function-configuration` response includes a `Layers` array, where each entry contains the ARN of the layer version and its size. This is useful for debugging deployment issues because the layer ARN includes the version number, allowing the developer to check if the referenced layer version exists in the account. In a real-world scenario, a deployment might fail if a layer version was deleted or if the function references a layer from a different region, which the configuration output can quickly reveal.
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.
