A Developer has been asked to make changes to the source code of an AWS Lambda function. The function is managed using an AWS CloudFormation template. The template is configured to load the source code from an Amazon S3 bucket. The Developer manually created a .ZIP file deployment package containing the changes and put the file into the correct location on Amazon S3. When the function is invoked, the code changes have not been applied.
What step is required to update the function with the changes?

• A.Delete the .ZIP file on S3, and re-upload by using a different object key name.
• B.Update the CloudFormation stack with the correct values for the function code properties S3Bucket, S3Key, or S3ObjectVersion.
• C.Ensure that the function source code is base64-encoded before uploading the deployment package to S3.
• D.Modify the execution role of the Lambda function to allow S3 access permission to the deployment package .ZIP file.

What is causing this issue?

• A.The developer needs to use the put-metric-data command.

An application is being developed to audit several AWS accounts. The application will run in Account A and must access AWS services in Accounts B and C.
What is the MOST secure way to allow the application to call AWS services in each audited account?

• A.Configure cross-account roles in each audited account. Write code in Account A that assumes those roles
• B.Use S3 cross-region replication to communicate among accounts, with Amazon S3 event notifications to trigger Lambda functions
• C.Deploy an application in each audited account with its own role. Have Account A authenticate with the application
• D.Create an IAM user with an access key in each audited account. Write code in Account A that uses those access keys

A developer has designed a customer, facing application that is running on an Amazon EC2 instance. The application logs every request made to it. The application usually runs seamlessly, but a spike in traffic generates several logs that cause the disk to fill up and eventually run out of memory Company policy requires old to be centralized for analysis.
Which long-term solution should the developer employ to prevent the issue from reoccurring?

• A.Enable AWS Auto Scaling on Amazon Elastic Block Store (Amazon EBS) to automatically add volumes to the instance when it reaches a specified threshold.
• B.Install the Amazon CloudWatch agent on the instance to send the logs to CloudWatch. Delete the logs from the instance once they are sent to CloudWatch.
• C.Create an Amazon EventBridge (Amazon CloudWatch Events) rule to pull the logs from the instance. Configure the rule to delete the logs they have been pulled.
• D.Enable AWS Auto Scaling on Amazon Elastic Block Store (Amazon EBS) a outomatically add volume to the instance when it reaches a specified threshold.
