Amazon AWS Certified Developer - Associate 認定 DVA-C02 試験問題 (Q17-Q22):

質問 # 17
A developer has an application that stores data in an Amazon S3 bucket. The application uses an HTTP API to store and retrieve objects. When the PutObject API operation adds objects to the S3 bucket the developer must encrypt these objects at rest by using server-side encryption with Amazon S3 managed keys (SSE-S3).
Which solution will meet this requirement?

A. Apply TLS to encrypt the traffic to the S3 bucket.
B. Set the x-amz-server-side-encryption header when invoking the PutObject API operation.
C. Provide the encryption key in the HTTP header of every request.
D. Create an AWS Key Management Service (AWS KMS) key. Assign the KMS key to the S3 bucket.

正解：B

解説：
Explanation
Amazon S3 supports server-side encryption, which encrypts data at rest on the server that stores the data. One of the encryption options is SSE-S3, which uses keys managed by S3. To use SSE-S3, the x-amz-server-side-encryption header must be set to AES256 when invoking the PutObject API operation. This instructs S3 to encrypt the object data with SSE-S3 before saving it on disks in its data centers and decrypt it when it is downloaded. Reference: Protecting data using server-side encryption with Amazon S3-managed encryption keys (SSE-S3)

A developer is writing an AWS Lambda function. The developer wants to log key events that occur while the Lambda function runs. The developer wants to include a unique identifier to associate the events with a specific function invocation. The developer adds the following code to the Lambda function:

Which solution will meet this requirement?

A. Obtain the request identifier from the AWS request ID field in the event object. Configure the application to write logs to standard output.
B. Obtain the request identifier from the AWS request ID field in the context object. Configure the application to write logs to standard output.
C. Obtain the request identifier from the AWS request ID field in the context object. Configure the application to write logs to a file.
D. Obtain the request identifier from the AWS request ID field in the event object. Configure the application to write logs to a file.

正解：B

解説：
Explanation
https://docs.aws.amazon.com/lambda/latest/dg/nodejs-context.html
https://docs.aws.amazon.com/lambda/latest/dg/nodejs-logging.html
There is no explicit information for the runtime, the code is written in Node.js.
AWS Lambda is a service that lets developers run code without provisioning or managing servers. The developer can use the AWS request ID field in the context object to obtain a unique identifier for each function invocation. The developer can configure the application to write logs to standard output, which will be captured by Amazon CloudWatch Logs. This solution will meet the requirement of logging key events with a unique identifier.

質問 # 19
An application uses Lambda functions to extract metadata from files uploaded to an S3 bucket; the metadata is stored in Amazon DynamoDB. The application starts behaving unexpectedly, and the developer wants to examine the logs of the Lambda function code for errors.
Based on this system configuration, where would the developer find the logs?

A. AWS CloudTrail
B. Amazon CloudWatch
C. Amazon DynamoDB
D. Amazon S3

正解：B

質問 # 20
A developer is creating an AWS Lambda function that consumes messages from an Amazon Simple Queue Service (Amazon SQS) standard queue. The developer notices that the Lambda function processes some messages multiple times.
How should developer resolve this issue MOST cost-effectively?

A. Change the Amazon SQS standard queue to an Amazon SQS FIFO queue by using the Amazon SQS message deduplication ID.
B. Change the message processing to use Amazon Kinesis Data Streams instead of Amazon SQS.
C. Set up a dead-letter queue.
D. Set the maximum concurrency limit of the AWS Lambda function to 1

正解：A

解説：
Explanation
Amazon Simple Queue Service (Amazon SQS) is a fully managed queue service that allows you to de-couple and scale for applications1. Amazon SQS offers two types of queues: Standard and FIFO (First In First Out) queues1. The FIFO queue uses the messageDeduplicationId property to treat messages with the same value as duplicate2. Therefore, changing the Amazon SQS standard queue to an Amazon SQS FIFO queue using the Amazon SQS message deduplication ID can help resolve the issue of the Lambda function processing some messages multiple times. Therefore, option A is correct.

質問 # 21
An application uses an Amazon EC2 Auto Scaling group. A developer notices that EC2 instances are taking a long time to become available during scale-out events. The UserData script is taking a long time to run.
The developer must implement a solution to decrease the time that elapses before an EC2 instance becomes available. The solution must make the most recent version of the application available at all times and must apply all available security updates. The solution also must minimize the number of images that are created. The images must be validated.
Which combination of steps should the developer take to meet these requirements? (Choose two.)

A. Use EC2 Image Builder to create an Amazon Machine Image (AMI). Install the latest version of the application and all the patches and agents that are needed to manage and run the application. Update the Auto Scaling group launch configuration to use the AMI.
B. Set up AWS CodeDeploy to deploy the most recent version of the application at runtime.
C. Use EC2 Image Builder to create an Amazon Machine Image (AMI). Install all the patches and agents that are needed to manage and run the application. Update the Auto Scaling group launch configuration to use the AMI.
D. Set up AWS CodePipeline to deploy the most recent version of the application at runtime.
E. Remove any commands that perform operating system patching from the UserData script.

正解：A、C
