질문 # 631
A company is offering APIs as a service over the internet to provide unauthenticated read access to statistical information that is updated daily. The company uses Amazon API Gateway and AWS Lambda to develop the APIs. The service has become popular, and the company wants to enhance the responsiveness of the APIs.
Which action can help the company achieve this goal?

A. Enable API caching in API Gateway.
B. Configure usage plans and API keys in API Gateway.
C. Configure API Gateway to use an interface VPC endpoint.
D. Enable cross-origin resource sharing (CORS) for the APIs.

정답：A

설명：
Amazon API Gateway is a service that enables developers to create, publish, maintain, monitor, and secure APIs at any scale. The developer can enable API caching in API Gateway to cache responses from the backend integration point for a specified time-to-live (TTL) period. This can improve the responsiveness of the APIs by reducing the number of calls made to the backend service.

질문 # 632
A developer deploys a custom application to three Amazon EC2 instances. The application processes messages from an Amazon Simple Queue Service (Amazon SQS) standard queue with default settings. When the developer runs a load test on the Amazon SQS queue, the developer discovers that the application processes many messages multiple times.
How can the developer ensure that the application processes each message exactly once?

A. Create a new SQS FIFO queue. Point the application to the new queue.
B. Modify the SQS standard queue to an SQS FIFO queue.
C. Increase the DelaySeconds value on the current SQS queue.
D. Process the messages on one EC2 instance instead of three instances.

정답：A

설명：
https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO- queues-moving.html Moving from a standard queue to a FIFO queue:
If you have an existing application that uses standard queues and you want to take advantage of the ordering or exactly-once processing features of FIFO queues, you need to configure the queue and your application correctly.
Note:
You can't convert an existing standard queue into a FIFO queue. To make the move, you must either create a new FIFO queue for your application or delete your existing standard queue and recreate it as a FIFO queue.

질문 # 633
A developer is working on a Python application that runs on Amazon EC2 instances. The developer wants to enable tracing of application requests to debug performance issues in the code.
Which combination of actions should the developer take to achieve this goal? (Select TWO)

A. Configure the application to write trace data to /Var/log-/xray.
B. Install the AWS X-Ray daemon on the EC2 instances.
C. Install the Amazon CloudWatch agent on the EC2 instances.
D. Install and configure the AWS X-Ray SDK for Python in the application.
E. Configure the application to write JSON-formatted togs to /var/log/cloudwatch.

정답：B,D

설명：
Explanation
This solution will meet the requirements by using AWS X-Ray to enable tracing of application requests to debug performance issues in the code. AWS X-Ray is a service that collects data about requests that the applications serve, and provides tools to view, filter, and gain insights into that data. The developer can install the AWS X-Ray daemon on the EC2 instances, which is a software that listens for traffic on UDP port 2000, gathers raw segment data, and relays it to the X-Ray API. The developer can also install and configure the AWS X-Ray SDK for Python in the application, which is a library that enables instrumenting Python code to generate and send trace data to the X-Ray daemon. Option A is not optimal because it will install the Amazon CloudWatch agent on the EC2 instances, which is a software that collects metrics and logs from EC2 instances and on-premises servers, not application performance data. Option C is not optimal because it will configure the application to write JSON-formatted logs to /var/log/cloudwatch, which is not a valid path or destination for CloudWatch logs. Option D is not optimal because it will configure the application to write trace data to
/var/log/xray, which is also not a valid path or destination for X-Ray trace data.

질문 # 634
A developer is using an AWS account to build an application that stores files in an Amazon S3 bucket. Files must be encrypted at rest by AWS KMS keys. A second AWS account must have access to read files from the bucket.
The developer wants to minimize operational overhead for the application.
Which combination of solutions will meet these requirements? (Select TWO.)

A. Create a bucket policy for the S3 bucket that grants s3:GetObject permissions to the second AWS account.
B. Create a service control policy (SCP) that grants s3:GetObject permissions to the second AWS account.
C. Use a customer managed key to encrypt the files. Create a key policy that grants kms: Decrypt permissions to the second AWS account.
D. Create a gateway endpoint for the S3 bucket. Modify the endpoint policy to grant s3:GetObject permissions to the second AWS account.
E. Use an AWS managed key to encrypt the files. Create a key policy that grants kms:Decrypt permissions to the second AWS account.

정답：A,C

설명：
Step-by-Step Breakdown:
Requirement Summary:
Encrypt S3 objects using KMS keys
Cross-account read access to another AWS account
Minimize operational overhead
Option A: Use a customer managed key + key policy granting kms:Decrypt to second account Correct: Customer managed keys allow full control of key policy.
You can add a statement to allow cross-account access using the second account's IAM principal.
Option B: Use AWS managed key + key policy granting access to second account Incorrect: AWS-managed KMS keys (aws/s3) cannot be modified to add cross-account access in key policies.
Option C: SCP that grants s3:GetObject to second account
Incorrect: SCPs are used to restrict or allow permissions across AWS Organizations, not to grant S3 or KMS access directly.
Option D: Create a bucket policy granting s3:GetObject to second account Correct: Bucket policies can grant cross-account access to specific IAM users or roles in the second account.
Option E: Gateway endpoint for S3 with cross-account access
Incorrect: Gateway endpoints only apply within the same VPC/account. Cross-account use with endpoint policies is not the correct pattern for this use case.
Cross-account S3 access with KMS: https://docs.aws.amazon.com/AmazonS3/latest/userguide/example- walkthroughs-managing-access-example2.html KMS cross-account key policy: https://docs.aws.amazon.com/kms/latest/developerguide/key-policy- modifying.html Bucket Policy for cross-account access: https://docs.aws.amazon.com/AmazonS3/latest/userguide/example- bucket-policies.html

질문 # 635
A developer has an application that is composed of many different AWS Lambda functions. The Lambda functions all use some of the same dependencies. To avoid security issues the developer is constantly updating the dependencies of all of the Lambda functions. The result is duplicated effort to reach function.
How can the developer keep the dependencies of the Lambda functions up to date with the LEAST additional complexity?

A. Use an AWS CodeCommit repository to host the dependencies in a centralized location.
B. Define a maintenance window for the Lambda functions to ensure that the functions get updated copies of the dependencies.
C. Upgrade the Lambda functions to the most recent runtime version.
D. Define a Lambda layer that contains all of the shared dependencies.

정답：D

설명：
This solution allows the developer to keep the dependencies of the Lambda functions up to date with the least additional complexity because it eliminates the need to update each function individually. A Lambda layer is a ZIP archive that contains libraries, custom runtimes, or other dependencies. The developer can create a layer that contains all of the shared dependencies and attach it to multiple Lambda functions. When the developer updates the layer, all of the functions that use the layer will have access to the latest version of the dependencies.
