Amazon AWS Certified Developer - Associate Sample Questions (Q648-Q653):

NEW QUESTION # 648
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. Change the AWS CloudFormation templates for us-east-1 and us-west-1 to use an AWS AMI. Relaunch the stack for both Regions.
B. 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
C. 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
D. Manually deploy the application outside AWS CloudFormation in us-west-1.

Answer: B

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.

NEW QUESTION # 649
A developer is building a microservices-based application by using Python on AWS and several AWS services The developer must use AWS X-Ray The developer views the service map by using the console to view the service dependencies. During testing, the developer notices that some services are missing from the service map What can the developer do to ensure that all services appear in the X-Ray service map?

A. Instrument the application by using the X-Ray SDK for Python. Install the X-Ray SDK for all the services that the application uses
B. Modify the X-Ray Python agent configuration in each service to increase the sampling rate
C. Increase the X-Ray service map timeout value in the X-Ray console
D. Enable X-Ray data aggregation in Amazon CloudWatch Logs for all the services that the application uses

Answer: A

Explanation:
AWS X-Ray SDK: The primary way to enable X-Ray tracing within applications. The SDK sends data about requests and subsegments to the X-Ray daemon for service map generation.
Instrumenting All Services: To visualize a complete microservice architecture on the service map, each relevant service must include the X-Ray SDK.

X-Ray SDK for Python: https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-python.html

NEW QUESTION # 650
A developer needs to set up an API to provide access to an application and its resources. The developer has a TLS certificate. The developer must have the ability to change the default base URL of the API to a custom domain name. The API users are distributed globally. The solution must minimize API latency.

A. Create an Amazon API Gateway REST API. Use the edge-optimized endpoint type. Import the TLS certificate into AWS Certificate Manager. Create a custom domain name for the REST API. Route traffic to the custom domain name. Disable the default endpoint for the REST API.
B. Create an Amazon API Gateway REST API. Use the private endpoint type. Import the TLS certificate into AWS Certificate Manager. Create a custom domain name for the REST API. Route traffic to the custom domain name. Disable the default endpoint for the REST API.
C. Create an Amazon CloudFront distribution that uses CloudFront Functions to process API requests.Import the TLS certificate into AWS Certificate Manager and CloudFront. Add the custom domain name as an alias resource record set that is for the CloudFront distribution.
D. Create an Amazon CloudFront distribution that uses an AWS Lambda@Edge function to process API requests. Import the TLS certificate into AWS Certificate Manager and CloudFront. Add the custom domain name as an alias resource record set that is for the CloudFront distribution.

Answer: A

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* Option C: Edge-Optimized API Gateway with Custom Domain Name:
* Edge-Optimized API Gateway:This endpoint type automatically leverages the Amazon CloudFront global distribution network, minimizing latency for API users distributed globally.
* Custom Domain Name:API Gateway supports custom domain names for APIs. Importing the TLS certificate into AWS Certificate Manager (ACM) and associating it with the custom domain name ensures secure connections.
* Disabling the Default Endpoint:Prevents direct access via the default API Gateway URL, enforcing the use of the custom domain name.
* Why Other Options Are Incorrect:
* Option A:While CloudFront can distribute API requests globally, API Gateway with edge- optimized endpoints already provides this functionality natively without requiring Lambda@Edge.
* Option B:Private endpoint types are used for internal access via VPC, which does not meet the global distribution and low-latency requirement.
* Option D:CloudFront Functions are not needed because API Gateway's edge-optimized endpoints handle global distribution efficiently.

NEW QUESTION # 651
A company is implementing an application on Amazon EC2 instances. The application needs to process incoming transactions. When the application detects a transaction that is not valid, the application must send a chat message to the company's support team. To send the message, the application needs to retrieve the access token to authenticate by using the chat API.
A developer needs to implement a solution to store the access token. The access token must be encrypted at rest and in transit. The access token must also be accessible from other AWS accounts.
Which solution will meet these requirements with the LEAST management overhead?

A. Use an AWS Systems Manager Parameter Store SecureString parameter that uses an AWS Key Management Service (AWS KMS) AWS managed key to store the access token. Add a resource-based policy to the parameter to allow access from other accounts. Update the IAM role of the EC2 instances with permissions to access Parameter Store. Retrieve the token from Parameter Store with the decrypt flag enabled. Use the decrypted access token to send the message to the chat.
B. Encrypt the access token by using an AWS Key Management Service (AWS KMS) customer managed key. Store the access token in an Amazon DynamoDB table. Update the IAM role of the EC2 instances with permissions to access DynamoDB and AWS KMS. Retrieve the token from DynamoDB. Decrypt the token by using AWS KMS on the EC2 instances. Use the decrypted access token to send the message to the chat.
C. Encrypt the access token by using an AWS Key Management Service (AWS KMS) AWS managed key. Store the access token in an Amazon S3 bucket. Add a bucket policy to the S3 bucket to allow access from other accounts. Update the IAM role of the EC2 instances with permissions to access Amazon S3 and AWS KMS. Retrieve the token from the S3 bucket. Decrypt the token by using AWS KMS on the EC2 instances. Use the decrypted access token to send the massage to the chat.
D. Use AWS Secrets Manager with an AWS Key Management Service (AWS KMS) customer managed key to store the access token. Add a resource-based policy to the secret to allow access from other accounts. Update the IAM role of the EC2 instances with permissions to access Secrets Manager. Retrieve the token from Secrets Manager. Use the decrypted access token to send the message to the chat.

Answer: D

NEW QUESTION # 652
A company runs its website on AWS. The company posts daily polls on its website and publishes the poll results next day. The website stores user responses in an Amazon DynamoDB table.
After the poll results are published, the company does not need to keep the user responses.
A developer needs to implement a solution that will automatically remove old user responses from the DynamoDB table. The developer adds a new expiration_date attribute to the DynamoDB table. The developer plans to use the expiration_date attribute for the automation.
Which solution will meet these requirements with the LEAST development effort?

A. Create an AWS Fargate task in Amazon Elastic Container Service (Amazon ECS) to delete old user responses based on the expiration_date attribute. Create an Amazon EventBridge schedule to run the Fargate task daily.
B. Enable TTL on the DynamoDB table and specify the expiration_date attribute. Expire old user responses by using DynamoDB TTL.
C. Create an AWS Lambda function to delete old user responses based on the expiration_date attribute. Create an Amazon EventBridge schedule to run the Lambda function daily.
D. Create an AWS Glue job to delete old user responses based on the expiration_date attribute.
Create an AWS Glue trigger schedule to run the job daily.

Answer: B
