Amazon AWS Certified Developer - Associate Sample Questions (Q559-Q564):

NEW QUESTION # 559
A developer is publishing critical log data to a log group in Amazon CloudWatch Logs. The log group was created 2 months ago. The developer must encrypt the log data by using an AWS Key Management Service (AWS KMS) key so that future data can be encrypted to comply with the company's security policy.
Which solution will meet this requirement with the LEAST effort?

Answer: A

Explanation:
https://docs.aws.amazon.com/cli/latest/reference/logs/associate-kms-key.html


NEW QUESTION # 560
A developer has observed an increase in bugs in the AWS Lambda functions that a development team has deployed in its Node is application. To minimize these bugs, the developer wants to impendent automated testing of Lambda functions in an environment that Closely simulates the Lambda environment.
The developer needs to give other developers the ability to run the tests locally. The developer also needs to integrate the tests into the team's continuous integration and continuous delivery (Ct/CO) pipeline before the AWS Cloud Development Kit (AWS COK) deployment.
Which solution will meet these requirements?

Answer: D

Explanation:
This solution will meet the requirements by using AWS SAM CLI tool, which is a command line tool that lets developers locally build, test, debug, and deploy serverless applications defined by AWS SAM templates. The developer can use sam local generate-event command to generate sample events for different event sources such as API Gateway or S3. The developer can create automated test scripts that use sam local invoke command to invoke Lambda functions locally in an environment that closely simulates Lambda environment.
The developer can check the response from Lambda functions and document how to run the test scripts for other developers on the team. The developer can also update CI/CD pipeline to run these test scripts before deploying with AWS CDK. Option A is not optimal because it will use cdk local invoke command, which does not exist in AWS CDK CLI tool. Option B is not optimal because it will use a unit testing framework that reproduces Lambda execution environment, which may not be accurate or consistent with Lambda environment. Option D is not optimal because it will create a Docker container from Node.js base image to invoke Lambda functions, which may introduce additional overhead and complexity for creating and running Docker containers.


NEW QUESTION # 561
A developer is testing a new file storage application that uses an Amazon CloudFront distribution to serve content from an Amazon S3 bucket. The distribution accesses the S3 bucket by using an origin access identity (OAI). The S3 bucket's permissions explicitly deny access to all other users.
The application prompts users to authenticate on a login page and then uses signed cookies to allow users to access their personal storage directories. The developer has configured the distribution to use its default cache behavior with restricted viewer access and has set the origin to point to the S3 bucket. However, when the developer tries to navigate to the login page, the developer receives a 403 Forbidden error.
The developer needs to implement a solution to allow unauthenticated access to the login page. The solution also must keep all private content secure.
Which solution will meet these requirements?

Answer: B


NEW QUESTION # 562
An application includes an Amazon DynamoDB table that is named orders. The table has a primary partition key of id and a global secondary index (GSI) that is named an accountIndex.
The GSI has a partition key of accountId and a sort key of orderDateTime.
A developer needs to create an AWS Lambda function to retrieve the orders that have an accountId of 100.
Which solution will meet this requirement by using the LEAST read capacity?

Answer: A

Explanation:
The Query action is the most efficient choice for this scenario. It retrieves items from a table or index based on the specified partition key (accountId) and can optionally use the sort key (orderDateTime) for additional filtering. By querying the accountIndex GSI with a KeyConditionExpression, you directly retrieve only the relevant items without scanning unnecessary data, minimizing read capacity usage.


NEW QUESTION # 563
A company hosts its application on AWS. The application runs on an Amazon Elastic Container Service (Amazon ECS) cluster that uses AWS Fargate. The cluster runs behind an Application Load Balancer. The application stores data in an Amazon Aurora database. A developer encrypts and manages database credentials inside the application.
The company wants to use a more secure credential storage method and implement periodic credential rotation.
Which solution will meet these requirements with the LEAST operational overhead?

Answer: A


NEW QUESTION # 564
