Question 1

A developer has a user account in the Development AWS account. He has been asked to modify resources in a Production AWS account. What is the MOST secure way to provide temporary access to the developer?

A : Use AWS KMS to generate cross-account customer master keys and use those get short-lived credentials

B : Generate an access key on the second account using the root account and share the access keys with the developer for API access

C : Add the user to a group in the second account that has a role attached granting the necessary permissions

D : Create a cross-account access role, and use sts:AssumeRole API to get short-lived credentials

Answer: D

Question 2

A developer is modifying an existing AWS Lambda function. While checking the code, the developer notices hardcoded parameter values for an Amazon RDS for SQL Server user name, password, database, host, and port. There are also hardcoded parameter values for an Amazon DynamoDB table, an Amazon S3 bucket, and an Amazon Simple Notification Service (Amazon SNS) topic.

The developer wants to securely store the parameter values outside the code in an encrypted format and wants to turn on rotation for the credentials. The developer also wants to be able to reuse the parameter values from other applications and to update the parameter values without modifying code.

Which solution will meet these requirements with the LEAST operational overhead?

A : Create an RDS database secret in AWS Secrets Manager. Set the user name, password, database, host, and port. Turn on secret rotation. Create encrypted Lambda environment variables for the DynamoDB table, S3 bucket, and SNS topic.

B : Create an RDS database secret in AWS Secrets Manager. Set the user name, password, database, host, and port. Turn on secret rotation. Create SecureString parameters in AWS Systems Manager Parameter Store for the DynamoDB table, S3 bucket, and SNS topic.

C : Create RDS database parameters in AWS Systems Manager Parameter Store for the user name, password, database, host, and port. Create encrypted Lambda environment variables for the DynamoDB table, S3 bucket, and SNS topic. Create a Lambda function and set the logic for the credentials rotation task. Schedule the credentials rotation task in Amazon EventBridge.

D : Create RDS database parameters in AWS Systems Manager Parameter Store for the user name, password, database, host, and port. Store the DynamoDB table, S3 bucket, and SNS topic in Amazon S3. Create a Lambda function and set the logic for the credentials rotation. Invoke the Lambda function on a schedule.

Answer: B

Question 3

An Amazon Simple Queue Service (Amazon SQS) queue serves as an event source for an AWS Lambda function. In the SQS queue, each item corresponds to a video file that the Lambda function must convert to a smaller resolution. The Lambda function is timing out on longer video files, but the Lambda function's timeout is already configured to its maximum value.

What should a developer do to avoid the timeouts without additional code changes?

A : Increase the memory configuration of the Lambda function.

B : Increase the visibility timeout on the SQS queue.

C : Use multi-threading for the conversion.

Answer: C

Question 4

A company is using AWS Lambda for processing small images that are uploaded to Amazon S3. This was working well until a large number of small files (several thousand) were recently uploaded and an error was generated by AWS Lambda (status code 429).

What is the MOST likely cause?

A : The event source mapping has not been configured

B : Amazon S3 could not handle the sudden burst in traffic

C : Lambda cannot process multiple files simultaneously

D : The concurrency execution limit for the account has been exceeded

Answer: D

Question 5

A company has hired a team of remote Developers. The Developers need to work programmatically with AWS resources from their laptop computers.

Which security components MUST the Developers use to authenticate? (Select TWO.)

A : Secret access key

B : Access key ID

C : Console password

D : MFA device

E : IAM user ID

Answer: A,B
