Exam AWS Certified Developer - Associate DVA-C02 topic 1 question 43 discussion

A A Lambda function has access to local storage in the /tmp directory. Each execution environment provides between 512 MB and 10,240 MB, in 1-MB increments, of disk space in the /tmp directory. https://docs.aws.amazon.com/lambda/latest/dg/foundation-progmodel.html

A) Correct - AWS Lambda provides a /tmp directory with storage between 51B to 10,240 MB. https://docs.aws.amazon.com/lambda/latest/dg/configuration-ephemeral-storage.html. The files in this directory are ephemeral and will be deleted after the function execution ends. B) Eliminated - Temporary files are not required to persist beyond the invocation, and using EFS would increase complexity and cost. C) Eliminated - Lambda does not directly support EBS volumes D) Eliminated- While S3 can store temporary data, it is not optimized for high-speed read/write operations during a Lambda invocation. Additionally, the use case specifies that the files do not need to be saved or retrieved later, making S3 an unnecessary overhead.

A is the correct answer.

The correct answer is A The /tmp directory is the recommended location for storing temporary files within an AWS Lambda function. The /tmp directory provides a writable space with a local storage capacity of 512 MB. It is specifically designed for temporary storage within the Lambda execution environment.
