Amazon AWS Certified Developer - Associate Sample Questions (Q377-Q382):

NEW QUESTION # 377
A developer is running an application on an Amazon EC2 instance. When the application tries to read an Amazon S3 bucket, the application fails. The developer notices that the associated IAM role is missing the S3 read permission. The developer needs to give the application the ability to read the S3 bucket.
Which solution will meet this requirement with the LEAST application disruption?

A. Add the permission to the role so that the change will take effect automatically.
B. Add the permission to the role. Hibernate and restart the existing EC2 instance.
C. Add the permission to the S3 bucket. Restart the EC2 instance.
D. Add the permission to the role. Terminate the existing EC2 instance. Launch a new EC2 instance.

Answer: A

NEW QUESTION # 378
A developer has written the following IAM policy to provide access to an Amazon S3 bucket:

Which access does the policy allow regarding the s3:GetObject and s3:PutObject actions?

A. Access on all buckets except the "DOC-EXAMPLE-BUCKET" bucket
B. Access on all buckets that start with "DOC-EXAMPLE-BUCKET" except the "DOC-EXAMPLE- BUCKET/secrets" bucket
C. Access on all objects in the "DOC-EXAMPLE-BUCKET" bucket except on objects that start with
"secrets"
D. Access on all objects in the "DOC-EXAMPLE-BUCKET" bucket along with access to all S3 actions for objects in the "DOC-EXAMPLE-BUCKET" bucket that start with "secrets"

Answer: C

Explanation:
The IAM policy shown in the image is a resource-based policy that grants or denies access to an S3 bucket based on certain conditions. The first statement allows access to any S3 action on any object in the "DOC- EXAMPLE-BUCKET" bucket when the request is made over HTTPS (the value of aws:SecureTransport is true). The second statement denies access to the s3:GetObject and s3:PutObject actions on any object in the
"DOC-EXAMPLE-BUCKET/secrets" prefix when the request is made over HTTP (the value of aws:
SecureTransport is false). Therefore, the policy allows access on all objects in the "DOC-EXAMPLE- BUCKET" bucket except on objects that start with "secrets". Reference: Using IAM policies for Amazon S3

NEW QUESTION # 379
A developer is designing a new feature for an existing application. The new feature uses an AWS Lambda function. The developer wants to test the Lambda function safely in a development AWS account and a testing AWS account before deploying the function into a production AWS account. The developer must roll back the function if issues are found. Which solution will meet these requirements with the LEAST operational overhead?

A. Update the Lambda function code to use environment variables for the development, testing, and production accounts. Use the environment variables to make code updates available to specific environments.
B. Create new Lambda function versions and aliases for the development, testing, and production accounts. After successful testing, update the production alias to point to the function. Roll back to the most recent stable function version if issues are discovered.
C. Deploy the Lambda function to the development, testing, and production accounts separately after successfully testing the function in each environment.
D. Use Lambda layers to separate the code and the libraries that are associated with each AWS account.
Deploy and test the Lambda function with each Lambda layer in each environment.

Answer: B

Explanation:
Using Versions and Aliases is the native AWS Lambda mechanism for managing deployments. A version is an immutable snapshot of your code and configuration. An alias (like " PROD " ) is a pointer to a specific version. By updating the alias to point to a new version, you promote code. If a bug is found, you simply point the alias back to the previous version, enabling an instantaneous rollback with minimal overhead.

NEW QUESTION # 380
A company regularly receives route status updates from its delivery trucks as events in Amazon EventBridge.
The company is building an API-based application in a VPC that will consume and process the events to create a delivery status dashboard. The API application must not be available by using public IP addresses because of security and compliance requirements.
How should the company send events from EventBridge to the API application?

A. Create an internet-facing Network Load Balancer (NLB) in front of the API application. Associate a security group with rules that block access from all external sources except for EventBridge. Configure the NLB as an EventBridge target.
B. Create an internet-facing Application Load Balancer (ALB) in front of the API application. Associate a security group with rules that block access from all external sources except for EventBridge. Configure the ALB as an EventBridge target.
C. Create an AWS Lambda function that runs in the same VPC as the API application. Configure the function as an EventBridge target. Use the function to send events to the API.
D. Use the application API endpoint in the VPC as a target for EventBridge. Send events directly to the application API endpoint from EventBridge.

Answer: C

Explanation:
* Why Option A is Correct:Running an AWS Lambda function within the same VPC ensures secure communication without exposing the API application to public IP addresses. The Lambda function can serve as a secure EventBridge target to send events to the API.
* Why Other Options are Incorrect:
* Option B & C: Internet-facing load balancers expose public IP addresses, which violates compliance requirements.
* Option D: EventBridge cannot directly target an endpoint within a private VPC without intermediary services like Lambda.
* AWS Documentation References:
* EventBridge Targets

NEW QUESTION # 381
A developer is using AWS Amplify Hosting to build and deploy an application. The developer is receiving an increased number of bug reports from users. The developer wants to add end-to-end testing to the application to eliminate as many bugs as possible before the bugs reach production.
Which solution should the developer implement to meet these requirements?

A. Add a test phase to the aws-exports.js file for the application.
B. Create unit tests in the application. Deploy the unit tests by using the amplify push command in the Amplify CLI.
C. Run the amplify add test command in the Amplify CLI.
D. Add a test phase to the amplify.yml build settings for the application.

Answer: D

Explanation:
The solution that will meet the requirements is to add a test phase to the amplify.yml build settings for the application. This way, the developer can run end-to-end tests on every code commit and catch any bugs before deploying to production. The other options either do not support end-to-end testing, or do not run tests automatically.
Reference: End-to-end testing
