The maximum size for an uncompressed deployment package for Lambda is _________.
- 1 GB
- 100 MB
- 250 MB
- 500 MB
1000 MB exceeds the maximum size limit for an uncompressed deployment package in AWS Lambda; the correct answer is 250 MB.

AWS Lambda has various limits and quotas, including limits on concurrent executions, invocation payload size, execution duration, and memory allocation.
What happens if a Lambda function exceeds its concurrent execution limit?
- Additional invocations are throttled
- The function automatically scales up to accommodate the load
- The function is paused until resources become available
- The function is terminated
If a Lambda function exceeds its concurrent execution limit, additional invocations beyond the limit are throttled, preventing them from executing until resources become available.
What is the default maximum execution time limit for an AWS Lambda function?
- 1 minute
- 15 minutes
- 30 seconds
- 5 hours
