DVA-C02 Deployment Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✓

  aws lambda update-function-code

  Why this is correct

  aws lambda update-function-code is the correct command because it uploads a new deployment package (ZIP file or container image) to the Lambda service, replacing the code currently associated with the function. This command updates the function's code while preserving its configuration, and it operates on the $LATEST version unless you specify a different qualifying qualifier, making it the proper way to deploy a new code version.

• ✗

  aws lambda update-function-configuration

  Why it's wrong here

  aws lambda update-function-configuration is incorrect because it modifies the function's runtime, memory limit, timeout, environment variables, VPC settings, and IAM role, but it does not alter the code logic itself. Updating the configuration alone leaves the current code in place, so it cannot introduce a new version of the application logic.

• ✗

  aws lambda invoke

  Why it's wrong here

  aws lambda invoke is incorrect because it only synchronously or asynchronously executes the currently deployed Lambda function and returns the invocation response, execution status, and logs. It performs no write operations on the function's code or configuration, so it cannot update any aspect of the function, let alone deploy a new version.

• ✗

  aws lambda create-function

  Why it's wrong here

  aws lambda create-function is incorrect because this command provisions an entirely new Lambda function resource, including its unique function name, execution role, and handler. Running it against an existing function name will fail or require deleting the current function first, so it cannot be used to deploy a new version of an already deployed function.
