Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q59-Q64):

質問 # 59
You have been doing a lot of testing of your VPC Network by deliberately failing EC2 instances to test whether instances are failing over properly. Your customer who will be paying the AWS bill for all this asks you if he being charged for all these instances. You try to explain to him how the billing works on EC2 instances to the best of your knowledge. What would be an appropriate response to give to the customer in regards to this?

A. Billing only commences only after 1 hour of uptime and billing ends when the instance terminates.
B. Billing commences when Amazon EC2 initiates the boot sequence of an AMI instance and billing ends when the instance shuts down.
C. Billing commences when Amazon EC2 initiates the boot sequence of an AMI instance and billing ends as soon as the instance starts to shutdown.
D. Billing commences when Amazon EC2 AMI instance is completely up and billing ends as soon as the instance starts to shutdown.

正解：B

解説：
Billing commences when Amazon EC2 initiates the boot sequence of an AMI instance. Billing ends when the instance shuts down, which could occur through a web services command, by running "shutdown -h", or through instance failure.

質問 # 60
A company is planning to securely manage one-time fixed license keys in AWS. The company's development team needs to access the license keys in automaton scripts that run in Amazon EC2 instances and in AWS CloudFormation stacks.
Which solution will meet these requirements MOST cost-effectively?

A. CloudFormation NoEcho parameters
B. Amazon S3 with encrypted files prefixed with "config"
C. AWS Secrets Manager secrets with a tag that is named SecretString
D. AWS Systems Manager Parameter Store SecureString parameters

正解：D

解説：
AWS Systems Manager Parameter Store is a service that provides secure, hierarchical storage for configuration data and secrets. Parameter Store supports SecureString parameters, which are encrypted using AWS Key Management Service (AWS KMS) keys. SecureString parameters can be used to store license keys in AWS and retrieve them securely from automation scripts that run in EC2 instances or CloudFormation stacks. Parameter Store is a cost-effective solution because it does not charge for storing parameters or API calls. Reference: Working with Systems Manager parameters

質問 # 61
A developer needs to perform geographic load testing of an API. The developer must deploy resources to multiple AWS Regions to support the load testing of the API.
How can the developer meet these requirements without additional application code?

A. Create and deploy an AWS Lambda function in each desired Region. Configure the Lambda function to create a stack from an AWS CloudFormation template in that Region when the function is invoked.
B. Create an AWS Systems Manager document that defines the resources. Use the document to create the resources in the desired Regions.
C. Create an AWS CloudFormation template that defines the load test resources. Use the AWS CLI deploy command to create a stack from the template in each Region.
D. Create an AWS CloudFormation template that defines the load test resources. Use the AWS CLI create-stack-set command to create a stack set in the desired Regions.

正解：D

質問 # 62
A developer is building a new containerized application by using AWS Copilot. The developer uses the AWS Copilot command line interface (CLI) to deploy the application during development. The developer committed the application code to a new AWS CodeCommit repository. The developer must create an automated deployment process before releasing the new application to production.
What should the developer do to meet these requirements in the MOST operationally efficient way?

A. Define an AWS CloudFormation template for an AWS CodePipeline with CodeCommit as the source. Configure the template as an AWS Copilot CLI add-on. Use the AWS Copilot CLI to deploy the application.
B. Use the AWS Serverless Application Model (AWS SAM) CLI to bootstrap and initialize an AWS CodePipeline configuration. Use the CodeCommit repository as the source. Invoke the AWS Copilot CLI to build and deploy the application.
C. Create a buildspec file that invokes the AWS Copilot CLI commands to build and deploy the application. Use the AWS Copilot CLI to create an AWS CodePipeline that uses the CodeCommit repository in the source stage and AWS CodeBuild in the build stage.
D. Use the AWS Copilot CLI to define the AWS Copilot pipeline and to deploy the AWS CodePipeline. Select CodeCommit as the source for the AWS CodePipeline.

正解：D

質問 # 63
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 use the S3 GetObject API call and to return the object handle to the user
B. Create an 1AM user with an appropriate policy. Store the access key ID and secret access key on the EC2 instances
C. Modify the application to delegate requests to the S3 bucket.
D. Create an EC2 instance profile and role with an appropriate policy Associate the role with the EC2 instances
E. Modify the application to use the S3 GeneratePresignedUrl API call

正解：D、E

解説：
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
