This DVA-C02 practice question tests your understanding of security. 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
✓
The Lambda execution role must have s3:GetObject permission on the S3 bucket.
Lambda functions access code stored in S3 buckets using an IAM execution role. The execution role must include the `s3:GetObject` permission for the specific bucket and object path to allow the Lambda service to download the deployment package. Without this permission, the Lambda function will fail with an access denied error during initialization.
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 S3 bucket policy must grant access to the Lambda service.
Why it's wrong here
The execution role should have access.
✗
The Lambda function must be in a VPC with an S3 VPC endpoint.
Why it's wrong here
Not required; Lambda can access S3 through the internet.
✗
The S3 bucket must be configured as a static website with CloudFront.
Why it's wrong here
Not necessary.
✓
The Lambda execution role must have s3:GetObject permission on the S3 bucket.
Why this is correct
The role needs permission to read the code.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse resource-based policies (bucket policies) with identity-based policies (IAM roles), assuming a bucket policy granting access to the Lambda service principal is sufficient, when in fact the Lambda execution role must explicitly have the `s3:GetObject` permission.
Detailed technical explanation
How to think about this question
When you create a Lambda function from an S3 bucket, the Lambda service assumes the function's execution role to call `GetObject` on the specified bucket and key. The IAM policy must allow `s3:GetObject` on the exact resource ARN (e.g., `arn:aws:s3:::my-bucket/path/to/code.zip`). If the bucket uses SSE-KMS encryption, the execution role also needs `kms:Decrypt` permissions on the KMS key. This permission model ensures that only authorized functions can access the deployment package, preventing unauthorized code injection.

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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.

What is the correct answer to this question?
The correct answer is: The Lambda execution role must have s3:GetObject permission on the S3 bucket. — Lambda functions access code stored in S3 buckets using an IAM execution role. The execution role must include the `s3:GetObject` permission for the specific bucket and object path to allow the Lambda service to download the deployment package. Without this permission, the Lambda function will fail with an access denied error during initialization.
