Amazon AWS Certified Developer - Associate Sample Questions (Q54-Q59):

NEW QUESTION # 54
A company has an AWS Step Functions state machine named myStateMachine.
The company configured a service role for Step Functions. The developer must ensure that only the myStateMachine state machine can assume the service role.

  • A. "Condition": { "ArnLike": { "aws
    ":"arn:aws:states:ap-south-1:111111111111:stateMachine
    " } }
  • B. "Condition": { "ArnLike": { "aws
    ":"arn:aws:states:ap-south-1:*:stateMachine
    " } }

Answer: A

Explanation:
Comprehensive Detailed Step by Step Explanation with All AWS Developer Reference:
To ensure that only a specific AWS Step Functions state machine (myStateMachine) can assume the service role, you must configure the correct trust policy in AWS IAM.
Trust Policies: Trust policies determine which entities (services or users) are allowed to assume the role. In this case, we want to restrict the trust policy to only allow the specific state machine (myStateMachine) to assume the role.
Using ArnLike: The condition "ArnLike" is used to specify that the SourceArn (which refers to the ARN of the entity assuming the role) must match a specific ARN. Option A specifies the exact ARN of the myStateMachine state machine, ensuring that only this state machine can assume the role.
Option B: This option is incorrect because it uses a wildcard (*) for the account ID, which would allow any state machine in the ap-south-1 region to assume the role, not just the specific one.

NEW QUESTION # 55
A developer is creating an AWS Lambda function. The Lambda function needs an external library to connect to a third-party solution. The external library is a collection of files with a total size of
100 MB. The developer needs to make the external library available to the Lambda execution environment and reduce the Lambda package space.
Which solution will meet these requirements with the LEAST operational overhead?

  • A. Create an Amazon Elastic File System (Amazon EFS) volume. Upload the external library to the EFS volume. Mount the EFS volume in the Lambda function. Import the library by using the proper folder in the mount point.
  • B. Load the external library to the Lambda function's /tmp directory during deployment of the Lambda package. Import the library from the /tmp directory.
  • C. Create a Lambda layer to store the external library. Configure the Lambda function to use the layer.
  • D. Create an Amazon S3 bucket. Upload the external library into the S3 bucket. Mount the S3 bucket folder in the Lambda function. Import the library by using the proper folder in the mount point.

Answer: C

Explanation:
Create a Lambda layer to store the external library. Configure the Lambda function to use the layer. This will allow the developer to make the external library available to the Lambda execution environment without having to include it in the Lambda package, which will reduce the Lambda package space. Using a Lambda layer is a simple and straightforward solution that requires minimal operational overhead.

NEW QUESTION # 56
A company has an Amazon S3 bucket that contains sensitive data. The data must be encrypted in transit and at rest. The company encrypts the data in the S3 bucket by using an AWS Key Management Service (AWS KMS) key. A developer needs to grant several other AWS accounts the permission to use the S3 GetObject operation to retrieve the data from the S3 bucket.
How can the developer enforce that all requests to retrieve the data provide encryption in transit?

  • A. Define a resource-based policy on the KMS key to deny access when a request meets the condition of "aws:SecureTransport": "false".
  • B. Define a resource-based policy on the S3 bucket to deny access when a request meets the condition "aws:SecureTransport": "false".
  • C. Define a resource-based policy on the S3 bucket to allow access when a request meets the condition "aws:SecureTransport": "false".
  • D. Define a role-based policy on the other accounts' roles to deny access when a request meets the condition of "aws:SecureTransport": "false".

Answer: B

NEW QUESTION # 57
A developer is working on an application that processes operating data from IoT devices. Each IoT device uploads a data file once every hour to an Amazon S3 bucket. The developer wants to immediately process each data file when the data file is uploaded to Amazon S3.
The developer will use an AWS Lambda function to process the data files from Amazon S3. The Lambda function is configured with the S3 bucket information where the files are uploaded. The developer wants to configure the Lambda function to immediately invoke after each data file is uploaded.
Which solution will meet these requirements?

  • A. Add a trigger to the Lambda function. Select the S3 bucket as the source.
  • B. Add a layer to the Lambda function. Select the S3 bucket as the source.
  • C. Add an Amazon EventBridge event to the Lambda function. Select the S3 bucket as the source.
  • D. Add an asynchronous invocation to the Lambda function. Select the S3 bucket as the source.

Answer: A

Explanation:
Adding a trigger to your Lambda function is the solution that will meet these requirements. A trigger is an event that can invoke a Lambda function. In the case of this issue, the trigger must be an Amazon S3 event that fires when a new file is uploaded to the bucket.


NEW QUESTION # 58
A company has a web application that runs on Amazon EC2 instances with a custom Amazon Machine Image (AMI) The company uses AWS CloudFormation to provision the application The application runs in the us- east-1 Region, and the company needs to deploy the application to the us-west-1 Region An attempt to create the AWS CloudFormation stack in us-west-1 fails. An error message states that the AMI ID does not exist. A developer must resolve this error with a solution that uses the least amount of operational overhead Which solution meets these requirements?

  • A. Manually deploy the application outside AWS CloudFormation in us-west-1.
  • B. Build the custom AMI in us-west-1 Create a new AWS CloudFormation template to launch the stack in us-west-1 with the new AMI ID
  • C. Change the AWS CloudFormation templates for us-east-1 and us-west-1 to use an AWS AMI.
    Relaunch the stack for both Regions.
  • D. Copy the custom AMI from us-east-1 to us-west-1. Update the AWS CloudFormation template for us- west-1 to refer to AMI ID for the copied AMI Relaunch the stack

Answer: D

Explanation:
* Problem: CloudFormation can't find the custom AMI in the target region (us-west-1) because AMIs are region-specific.
* Copying AMIs:
* AMIs can be copied across regions, maintaining their configuration.
* This approach minimizes operational overhead as the existing CloudFormation template can be reused with a minor update.
* Updating the Template:
* Modify the CloudFormation template in us-west-1 to reference the newly copied AMI's ID in that region.
