Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q290-Q295):

質問 # 290
A company is preparing to migrate an application to the company's first AWS environment.
Before this migration, a developer is creating a proof-of-concept application to validate a model for building and deploying container-based applications on AWS.
Which combination of steps should the developer take to deploy the containerized proof-of- concept application with the LEAST operational effort? (Choose two.)

正解：B、D


質問 # 291
A company has an online web application that includes a product catalog. The catalog is stored in an Amazon S3 bucket that is named DOC-EXAMPLE-BUCKET. The application must be able to list the objects in the S3 bucket and must be able to download objects through an 1AM policy.
Which policy allows MINIMUM access to meet these requirements?

正解：B


質問 # 292
A development team uses AWS Lambda functions with reserved concurrency to support an application that processes data from an Amazon DynamoDB table. During peak hours, the development team observes a slowdown in the application. Some function invocations fail to run.
During less busy hours, the application runs smoothly, and all the Lambda functions run as expected.
The development team must investigate the root cause of the issue.
Which Lambda function metrics should the development team check to meet this requirement?

正解：B

解説：
The Throttles metric indicates when Lambda invocations are rejected due to exceeding reserved concurrency, and ConcurrentExecutions shows how many executions are happening simultaneously. Monitoring these Amazon CloudWatch metrics helps identify if the function is hitting concurrency limits during peak hours, which is likely the root cause of the observed slowdowns and failures.


質問 # 293
A developer is troubleshooting a three-tier application, which is deployed on Amazon EC2 instances. There is a connectivity problem between the application servers and the database servers.
Which AWS services or tools should be used to identity the faulty component? (Choose two.)

正解：C、D


質問 # 294
A company is concerned that a malicious user could deploy unauthorized changes to the code for an AWS Lambda function. What can a developer do to ensure that only trusted code is deployed to Lambda?

正解：A


質問 # 295
