A developer is creating an AWS Lambda function in VPC mode An Amazon S3 event will invoke the Lambda function when an object is uploaded into an S3 bucket The Lambda function will process the object and produce some analytic results that will be recorded into a file Each processed object will also generate a log entry that will be recorded into a file.

Other Lambda functions. AWS services, and on-premises resources must have access to the result files and log file. Each log entry must also be appended to the same shared log file. The developer needs a solution that can share files and append results into an existing file.

Which solution should the developer use to meet these requirements?

A.

Answers
D.
Create a reference to the /opt storage directory Store the result files and log file by using the directory reference Append the log entry to the log file
Suggested answer: A

Explanation:

Amazon EFS:A network file system (NFS) providing shared, scalable storage across multiple Lambda functions and other AWS resources.

Lambda Mounting:EFS file systems can be mounted within Lambda functions to access a shared storage space.

Log Appending:EFS supports appending data to existing files, making it ideal for the log file scenario.

Amazon EFS Documentation:https://docs.aws.amazon.com/efs/
