NEW QUESTION # 569

Which AWS service should the developer use to accomplish this goal?
Answer: D
NEW QUESTION # 570
A company runs an AWS CodeBuild project on medium-sized Amazon EC2 instances. The company wants to cost optimize the project and reduce the provisioning time.
Answer: D
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
* Option D: Set up Amazon S3 Caching for CodeBuild:
* CodeBuild supports S3 caching to store intermediate build artifacts and dependencies. This reduces the time required to download dependencies during subsequent builds, effectively lowering costs and improving build performance.
* By using S3 caching, developers can optimize costs without changing the compute type or adding complexity.
* Why Other Options Are Incorrect:
* Option A: CodeBuild does not have a "reserved capacity fleet" option.
* Option B: AWS Lambda cannot be used as the compute mode for CodeBuild projects.
CodeBuild uses its own managed build environments.
* Option C: CodeBuild already operates on an on-demand basis, so this does not address the need for optimization or reduced provisioning time.

NEW QUESTION # 571
A developer manages three AWS accounts. Each account contains an Amazon RDS DB instance in a private subnet. The developer needs to define users in each database in a consistent way.
The developer must ensure that the same users are created and updated later in all three accounts.
Which solution will meet these requirements with the MOST operational efficiency?
Answer: C
NEW QUESTION # 572
A company is using the AWS Serverless Application Model (AWS SAM) to develop a social media application. A developer needs a quick way to test AWS Lambda functions locally by using test event payloads. The developer needs the structure of these test event payloads to match the actual events that AWS services create.
Answer: C
Explanation:
Comprehensive Detailed Step by Step Explanation with All AWS Developer References:
The AWS Serverless Application Model (SAM) includes features for local testing and debugging of AWS Lambda functions. One of the most efficient ways to generate test payloads that match actual AWS event structures is by using the sam local generate-event command.
* sam local generate-event: This command allows developers to create pre-configured test event payloads for various AWS services (e.g., S3, API Gateway, SNS). These generated events accurately reflect the format that the service would use in a live environment, reducing the manual work required to create these events from scratch.
* Operational Overhead: This approach reduces overhead since the developer does not need to manually create or maintain test events. It ensures that the structure is correct and up-to-date with the latest AWS standards.
* Alternatives:
* Option A suggests using shareable test events, but manually creating or sharing these events introduces more overhead.
* Option B and C both involve manually storing and maintaining test events, which adds unnecessary complexity compared to using sam local generate-event.

NEW QUESTION # 573
A developer is building an application and wants to quickly test the effectiveness of a function before committing the code. Which solution will meet this requirement with the LEAST effort?
Answer: C
Explanation:
Amazon Q Developer can generate unit tests directly from selected code in the development environment. Highlighting the function and using the agent to generate a unit test provides the fastest way to validate the function before committing code.
