A developer is designing an AWS Lambda function to perform a maintenance activity.The developer will use Amazon EventBridge (Amazon CloudWatch Events) to invoke the function on an hourly schedule.The developer wants the function to log information at different levels of detail according to the value of a log level variable.The developer must design the function so that the log level can be set without requiring a change to the function code.

Which solution will meet these requirements?

Add a custom log level parameter for the Lambda function. Set the parameter by using the Lambda console

Set the log level in a Lambda environment variable

Set the log level in the Amazon CloudWatch Logs console.

Add a custom log level parameter for the Lambda function. Set the parameter by using the AWS CLI.

Explanations:

Lambda does not support custom parameters through the console; configuration must be managed through environment variables or specific parameter solutions.

Setting the log level in an environment variable allows the developer to control it without changing code and is a best practice for Lambda configuration.

The CloudWatch Logs console is used for viewing and managing logs, not for setting application-specific log levels.

Although parameters can be set via the AWS CLI, AWS Lambda does not support direct custom parameters; environment variables are recommended instead.
