최신 AWS Certified Associate DVA-C02 무료샘플문제 (Q612-Q617):

질문 # 612
A company has developed an application that uses AWS Lambda functions to process messages from an Amazon SQS queue. One of the Lambda functions makes a call to an external API that is expected to encounter temporary service unavailability.
A developer needs to configure the function to retry failed messages from an Amazon SQS dead-letter queue.
The developer notices that the Lambda function is re-processing some messages in the queue more than once.
Which solution will resolve this issue?

A. Set a receive message wait time for each message. Configure the Lambda function to add a MessageId to each message.
B. Set a message retention period for each message. Configure the Lambda function to add a MessageId to each message.
C. Set the visibility timeout parameter at the queue level. Configure the Lambda function to delete processed messages from the queue.
D. Set the delivery delay parameter at the queue level. Configure the Lambda function to delete processed messages from the queue.

정답：C

설명：
Comprehensive Detailed Explanation with all AWS References
* Why Option B is Correct:Setting the visibility timeout ensures that once a message is being processed, it is temporarily hidden from other consumers. The Lambda function must delete processed messages to avoid re-processing when the visibility timeout expires.
* Why Other Options are Incorrect:
* Option A: Message retention affects how long messages stay in the queue, not how they are processed.
* Option C: Receive message wait time optimizes long polling but does not prevent re-processing.
* Option D: Delivery delay introduces latency for new messages and does not address message re- processing.
* AWS Documentation References:
* Using SQS Visibility Timeout

질문 # 613
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?

A. Migrate the secret credentials to Amazon RDS parameter groups. Encrypt the parameter by using an AWS Key Management Service (AWS KMS) key Turn on secret rotation. Use 1AM policies and roles to grant AWS KMS permissions to access Amazon RDS.
B. Migrate the credentials to AWS Systems Manager Parameter Store. Encrypt the parameter by using an AWS Key Management Service (AWS KMS) key. Turn on secret rotation. Use 1AM policies and roles to grant Amazon ECS Fargate permissions to access to AWS Secrets Manager
C. Migrate the credentials to AWS Secrets Manager. Encrypt the credentials by using an AWS Key Management Service (AWS KMS) key Turn on secret rotation Use 1AM policies and roles to grant Amazon ECS Fargate permissions to access to AWS Secrets Manager by using keys.
D. Migrate the credentials to ECS Fargate environment variables. Encrypt the credentials by using an AWS Key Management Service (AWS KMS) key Turn on secret rotation. Use 1AM policies and roles to grant Amazon ECS Fargate permissions to access to AWS Secrets Manager.

정답：C

설명：
Explanation
AWS Secrets Manager is a service that helps you store, distribute, and rotate secrets securely. You can use Secrets Manager to migrate your credentials from your application code to a secure and encrypted storage.
You can also enable automatic rotation of your secrets by using AWS Lambda functions or custom logic. You can use IAM policies and roles to grant your Amazon ECS Fargate tasks permissions to access your secrets from Secrets Manager. This solution minimizes the operational overhead of managing your credentials and enhances the security of your application. References

질문 # 614
A company has an application that is hosted on Amazon EC2 instances The application stores objects in an Amazon S3 bucket and allows users to download objects from the S3 bucket A developer turns on S3 Block Public Access for the S3 bucket After this change, users report errors when they attempt to download objects The developer needs to implement a solution so that only users who are signed in to the application can access objects in the S3 bucket.
Which combination of steps will meet these requirements in the MOST secure way? (Select TWO.)

A. Modify the application to delegate requests to the S3 bucket.
B. Create an EC2 instance profile and role with an appropriate policy Associate the role with the EC2 instances
C. Create an 1AM user with an appropriate policy. Store the access key ID and secret access key on the EC2 instances
D. Modify the application to use the S3 GetObject API call and to return the object handle to the user
E. Modify the application to use the S3 GeneratePresignedUrl API call

정답：B,E

설명：
Explanation
The most secure way to allow the EC2 instances to access the S3 bucket is to use an EC2 instance profile and role with an appropriate policy that grants the necessary permissions. This way, the EC2 instances can use temporary security credentials that are automatically rotated and do not need to store any access keys on the instances. To allow the users who are signed in to the application to download objects from the S3 bucket, the application can use the S3 GeneratePresignedUrl API call to create a pre-signed URL that grants temporary access to a specific object. The pre-signed URL can be returned to the user, who can then use it to download the object within a specified time period. References

질문 # 615
A company has a social media application that receives large amounts of traffic User posts and interactions are continuously updated in an Amazon RDS database The data changes frequently, and the data types can be complex The application must serve read requests with minimal latency The application's current architecture struggles to deliver these rapid data updates efficiently The company needs a solution to improve the application's performance.
Which solution will meet these requirements'?

A. Set up Amazon S3 Transfer Acceleration on the RDS database to enhance the speed of data transfer from the databases to the application.
B. Use Amazon DynamoDB Accelerator (DAX) in front of the RDS database to provide a caching layer for the high volume of rapidly changing data
C. Add an Amazon CloudFront distribution in front of the RDS database to provide a caching layer for the high volume of rapidly changing data
D. Create an Amazon ElastiCache for Redis cluster. Update the application code to use a write-through caching strategy and read the data from Redis.

정답：D

설명：
Explanation
Creating an Amazon ElastiCache for Redis cluster is the best solution for improving the application's performance. Redis is an in-memory data store that can serve read requests with minimal latency and handle complex data types, such as lists, sets, hashes, and streams. By using a write-through caching strategy, the application can ensure that the data in Redis is always consistent with the data in RDS. The application can read the data from Redis instead of RDS, reducing the load on the database and improving the response time.
The other solutions are either not feasible or not effective. Amazon DynamoDB Accelerator (DAX) is a caching service that works only with DynamoDB, not RDS. Amazon S3 Transfer Acceleration is a feature that speeds up data transfers between S3 and clients across the internet, not between RDS and the application.
Amazon CloudFront is a content delivery network that can cache static content, such as images, videos, or HTML files, but not dynamic content, such as user posts and interactions. References

질문 # 616
A developer is working on an ecommerce website. The developer wants to review server logs without logging in to each of the application servers individually. The website runs on multiple Amazon EC2 instances, is written in Python, and needs to be highly available.
How can the developer update the application to meet these requirements with MINIMUM changes?

A. Scale down the application to one larger EC2 instance where only one instance is recording logs.
B. Install the unified Amazon CloudWatch agent on the EC2 instances. Configure the agent to push the application logs to CloudWatch.
C. Set up centralized logging by using Amazon OpenSearch Service, Logstash, and OpenSearch Dashboards.
D. Rewrite the application to be cloud native and to run on AWS Lambda, where the logs can be reviewed in Amazon CloudWatch.

정답：B

설명：
Option D is the best option because it requires minimum changes and leverages the existing infrastructure.
