Answer: A,E

NEW QUESTION # 163
A developer is creating an AWS Lambda function. The Lambda function will consume messages from an Amazon Simple Queue Service (Amazon SQS) queue. The developer wants to integrate unit testing as part of the function's continuous integration and continuous delivery (CI/CD) process.
How can the developer unit test the function?

A. Create an SQS queue for tests. Use this SQS queue in the application's unit test. Run the unit tests during the CI/CD process.
B. Create an AWS CloudFormation template that creates an SQS queue and deploys the Lambda function. Create a stack from the template during the CI/CD process. Invoke the deployed function. Verify the output.
C. Use the aws lambda invoke command with a test event during the CIICD process.
D. Create an SQS event for tests. Use a test that consumes messages from the SQS queue during the function's Cl/CD process.

Answer: A

Explanation:
Unit testing is a type of testing that verifies the correctness of individual units of source code, typically functions or methods. When unit testing a Lambda function that interacts with Amazon SQS, you can create a separate test SQS queue that the Lambda function interacts with during testing. You would then validate the behavior of the function based on its interactions with the test queue. This approach isolates the function's behavior from the rest of the system, which is a key principle of unit testing.

NEW QUESTION # 164
A developer is creating a mobile app that calls a backend service by using an Amazon API Gateway REST API. For integration testing during the development phase, the developer wants to simulate different backend responses without invoking the backend service.
Which solution will meet these requirements with the LEAST operational overhead?

A. Customize the API Gateway stage to select a response type based on the request.
B. Create an Amazon EC2 instance that serves the backend REST API by using an AWS CloudFormation template.
C. Create an AWS Lambda function. Use API Gateway proxy integration to return constant HTTP responses.
D. Use a request mapping template to select the mock integration response.

Answer: D

Explanation:
Explanation
Amazon API Gateway supports mock integration responses, which are predefined responses that can be returned without sending requests to a backend service. Mock integration responses can be used for testing or prototyping purposes, or for simulating different backend responses based on certain conditions. A request mapping template can be used to select a mock integration response based on an expression that evaluates some aspects of the request, such as headers, query strings, or body content. This solution does not require any additional resources or code changes and has the least operational overhead. Reference: Set up mock integrations for an API Gateway REST API

NEW QUESTION # 165
A developer created an AWS Lambda function that performs a series of operations that involve multiple AWS services. The function's duration time is higher than normal. To determine the cause of the issue, the developer must investigate traffic between the services without changing the function code.
Which solution will meet these requirements?

A. Review the AWS Config logs in Amazon CloudWatch.
B. Configure AWS CloudTrail. View the trail logs that are associated with the Lambda function.
C. Enable AWS X-Ray active tracing in the Lambda function. Review the logs in X-Ray.
D. Review the Amazon CloudWatch logs that are associated with the Lambda function.

Answer: D

NEW QUESTION # 166
A company hosts a client-side web application for one of its subsidiaries on Amazon S3. The web application can be accessed through Amazon CloudFront from https://www.example.com. After a successful rollout, the company wants to host three more client-side web applications for its remaining subsidiaries on three separate S3 buckets.
To achieve this goal, a developer moves all the common JavaScript files and web fonts to a central S3 bucket that serves the web applications. However, during testing, the developer notices that the browser blocks the JavaScript files and web fonts.
What should the developer do to prevent the browser from blocking the JavaScript files and web fonts?

A. Create four access points that allow access to the central S3 bucket. Assign an access point to each web application bucket.
B. Create a bucket policy that allows access to the central S3 bucket. Attach the bucket policy to the central S3 bucket.
C. Create a Content-MD5 header that provides a message integrity check for the central S3 bucket. Insert the Content-MD5 header for each web application request.
D. Create a cross-origin resource sharing (CORS) configuration that allows access to the central S3 bucket.
Add the CORS configuration to the central S3 bucket.

Answer: D

Explanation:
Explanation
This is a frequent trouble. Web applications cannot access the resources in other domains by default, except some exceptions. You must configure CORS on the resources to be accessed.
