최신 AWS Certified Associate DVA-C02 무료샘플문제 (Q744-Q749):

질문 # 744
A company has a multi-node Windows legacy application that runs on premises. The application uses a network shared folder as a centralized configuration repository to store configuration files in .xml format. The company is migrating the application to Amazon EC2 instances. As part of the migration to AWS, a developer must identify a solution that provides high availability for the repository.
Which solution will meet this requirement MOST cost-effectively?

A. Deploy a micro EC2 instance with an instance store volume. Use the host operating system to share a folder. Update the application code to read and write configuration files from the shared folder.
B. Mount an Amazon Elastic Block Store (Amazon EBS) volume onto one of the EC2 instances. Deploy a file system on the EBS volume. Use the host operating system to share a folder. Update the application code to read and write configuration files from the shared folder.
C. Create an Amazon S3 bucket to host the repository. Migrate the existing .xml files to the S3 bucket.
Mount the S3 bucket to the EC2 instances as a local volume. Update the application code to read and write configuration files from the disk.
D. Create an Amazon S3 bucket to host the repository. Migrate the existing .xml files to the S3 bucket.
Update the application code to use the AWS SDK to read and write configuration files from Amazon S3.

정답：D

설명：
Explanation
Amazon S3 is a service that provides highly scalable, durable, and secure object storage. The developer can create an S3 bucket to host the repository and migrate the existing .xml files to the S3 bucket. The developer can update the application code to use the AWS SDK to read and write configuration files from S3. This solution will meet the requirement of high availability for the repository in a cost-effective way.

질문 # 745
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 that start with "DOC-EXAMPLE-BUCKET" except the "DOC-EXAMPLE- BUCKET/secrets" bucket
B. 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"
C. Access on all objects in the "DOC-EXAMPLE-BUCKET" bucket except on objects that start with
"secrets"
D. Access on all buckets except the "DOC-EXAMPLE-BUCKET" bucket

정답：C

설명：
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

질문 # 746
A developer is setting up infrastructure by using AWS Cloud Formation. If an error occurs when the resources described in the CloudFormation template are provisioned, successfully provisioned resources must be preserved. The developer must provision and update the CloudFormation stack by using the AWS CLI.
Which solution will meet these requirements?

A. Add a -parameters ParameterKey=P reserve Resources. ParameterVaIue=True command line option to the create-stack command and the update-stack command.
B. Add an --enable-terminal ion-protection command line option to the create-stack command and the update-stack command.
C. Add a -disable-roll back command line option to the create-stack command and the update-stack command
D. Add a -tags Key=PreserveResources.VaIue=True command line option to the create-stack command and the update-stack command.

정답：C

질문 # 747
A company hosts a batch processing application on AWS Elastic Beanstalk with instances that run the most recent version of Amazon Linux. The application sorts and processes large datasets. In recent weeks, the application's performance has decreased significantly during a peak period for traffic. A developer suspects that the application issues are related to the memory usage. The developer checks the Elastic Beanstalk console and notices that memory usage is not being tracked.
How should the developer gather more information about the application performance issues?

A. Configure the Amazon CloudWatch agent to push logs to Amazon CloudWatch Logs by using port 443.
B. Configure the Amazon CloudWatch agent to track the memory usage of the instances.
C. Configure the Elastic Beanstalk .ebextensions directory to track the memory usage of the instances.
D. Configure an Amazon CloudWatch dashboard to track the memory usage of the instances.

정답：B

설명：
Comprehensive Detailed Explanation with all AWS References
To monitor memory usage in Amazon Elastic Beanstalk environments, it's important to understand that default Elastic Beanstalk monitoring capabilities in Amazon CloudWatch do not track memory usage, as memory metrics are not collected by default. Instead, the Amazon CloudWatch agent must be configured to collect memory usage metrics.
* Why Option C is Correct:
* The Amazon CloudWatch agent can be installed and configured to monitor system-level metrics such as memory and disk utilization.
* To enable memory tracking, developers need to install the CloudWatch agent on the Amazon Elastic Compute Cloud (EC2) instances associated with the Elastic Beanstalk environment.
* After installation, the agent can be configured to collect memory metrics, which can then be sent to CloudWatch for further analysis.
* How to Implement This Solution:
* Install the CloudWatch Agent:Use .ebextensions or AWS Systems Manager to install and configure the CloudWatch agent on the EC2 instances running in the Elastic Beanstalk environment.
* Modify CloudWatch Agent Configuration:Create a config.json file that specifies memory usage tracking and other desired metrics.
* Enable Metrics Reporting:The CloudWatch agent can push the metrics to CloudWatch, where they can be monitored.
* Why Other Options are Incorrect:
* Option A: Configuring the agent to push logs is not sufficient to track memory metrics. This option addresses logging but not system-level metrics like memory usage.
* Option B: The .ebextensions directory is used to customize Elastic Beanstalk environments but does not directly track memory metrics without additional configuration of the CloudWatch agent.
* Option D: Configuring a CloudWatch dashboard will only visualize the metrics that are already being collected. It will not enable memory usage tracking.
* AWS Documentation References:
* Amazon CloudWatch Agent Overview
* Elastic Beanstalk Customization Using .ebextensions
* Monitoring Custom Metrics

질문 # 748
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?

A. Install the AWS Serverless Application Model (AWS SAW) CLI tool Use the Sam local generate-event command to generate sample events for me automated tests. Create automated test scripts that use the Sam local invoke command to invoke the Lambda functions. Check the response Document the test scripts tor the other developers on the team Update the CI/CD pipeline to run the test scripts.
B. Create sample events based on the Lambda documentation. Create automated test scripts that use the cdk local invoke command to invoke the Lambda functions. Check the response Document the test scripts for the other developers on the team Update the CI/CD pipeline to run the test scripts.
C. Install a unit testing framework that reproduces the Lambda execution environment. Create sample events based on the Lambda Documentation Invoke the handler function by using a unit testing framework. Check the response Document how to run the unit testing framework for the other developers on the team. Update the OCD pipeline to run the unit testing framework.
D. Create sample events based on the Lambda documentation. Create a Docker container from the Node is base image to invoke the Lambda functions. Check the response Document how to run the Docker container for the more developers on the team update the CI/CD pipeline to run the Docker container.

정답：A

설명：
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.
