The developer does not want tomodify the Lambda code if the table name changes.Which solution will meet these requirements MOST efficiently?

A : Create a Lambda environment variable to store the table name. Use the standard method for theprogramming language to retrieve the variable.

B : Store the table name in a file. Store the file in the /tmp folder. Use the SDK for the programminglanguage to retrieve the table name.

C : Create a file to store the table name. Zip the file and upload the file to the Lambda layer. Use the SDKfor the programming language to retrieve the table name.

D : Create a global variable that is outside the handler in the Lambda function to store the table name.

Answer: C

Question 2

B : Use a compression algorithm that is more efficient than ZIP.

C : Break up the function into multiple smaller functions.

D : Zip the .zip file twice to compress the file more.

E : Move common libraries, function dependencies, and custom runtimes into Lambda layers.

Answer: C,E

The solution must give the company the ability to defer the messages with errors and save thesemessages for further analysis. What is the MOST operationally efficient solution that meets theserequirements?

A : Configure Amazon CloudWatch Logs to save the error messages to a separate log stream.

B : Create a new SQS queue. Set the new queue as a dead-letter queue for the application queue. Configurethe Maximum Receives setting.
