- A
Upload the Lambda deployment package to Amazon S3 and reference it from the function
S3 allows larger packages.
- B
Increase the Lambda function's timeout setting
Why wrong: Timeout is unrelated to code size.
- C
Use Amazon CloudFront to distribute the Lambda code
Why wrong: CloudFront is for content delivery, not Lambda.
- D
Enable AWS X-Ray tracing on the Lambda function
Why wrong: X-Ray is for debugging, not code size.
Question 761 of 1,616
Lambda Deployment Package Size Limit — S3 Workaround
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 is deploying a new version of a Lambda function using an AWS CodePipeline pipeline. The deployment fails during the 'Deploy' stage with an error indicating that the function's code is too large. What should the developer do to resolve this issue?
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
✓
Upload the Lambda deployment package to Amazon S3 and reference it from the function
AWS Lambda has a hard limit of 50 MB for direct uploads via the console or API. When a deployment package exceeds this limit, the correct approach is to upload the package to Amazon S3 and configure the Lambda function to reference the S3 object. CodePipeline can then use the S3 location to deploy the function, bypassing the direct upload size restriction.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse Lambda's execution timeout or memory limits with the deployment package size limit, or incorrectly assume that CloudFront can serve as a storage backend for Lambda code.
Detailed technical explanation
How to think about this question
Lambda deployment packages can be up to 250 MB when stored in S3 and referenced via the `S3Bucket`, `S3Key`, and `S3ObjectVersion` parameters in the `CreateFunction` or `UpdateFunctionCode` API. The 50 MB direct upload limit applies to the `ZipFile` parameter, which is base64-encoded and sent inline. For larger packages, the S3 approach is mandatory, and CodePipeline can automate this by using the `LambdaFunction` deployment action with the S3 artifact.
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 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.

AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
