질문 # 142
A developer has observed an increase in bugs in the AWS Lambda functions that a development team has deployed in its Node.js application. To minimize these bugs, the developer wants to implement automated testing of Lambda functions in an environment that closely simulates the Lambda environment.
The developer needs to give other developers the ability to run the tests locally. The developer also needs to integrate the tests into the team's continuous integration and continuous delivery (CI/CD) pipeline before the AWS Cloud Development Kit (AWS CDK) deployment.
Which solution will meet these requirements?

A. Install a unit testing framework that reproduces the Lambda execution environment. Create sample events based on the Lambda documentation. Invoke the handler function by using a unit testing framework. Check the response. Document how to run the unit testing framework for the other developers on the team. Update the CI/CD pipeline to run the unit testing framework.
B. Create sample events based on the Lambda documentation. Create automated test scripts that use the cdk local invoke command to invoke the Lambda functions. Check the response.
Document the test scripts for the other developers on the team. Update the CI/CD pipeline to run the test scripts.
C. Install the AWS Serverless Application Model (AWS SAM) CLI tool. Use the sam local generate- event command to generate sample events for the automated tests. Create automated test scripts that use the sam local invoke command to invoke the Lambda functions. Check the response. Document the test scripts for the other developers on the team. Update the CI/CD pipeline to run the test scripts.
D. Create sample events based on the Lambda documentation. Create a Docker container from the Node.js base image to invoke the Lambda functions. Check the response. Document how to run the Docker container for the other developers on the team. Update the CI/CD pipeline to run the Docker container.

정답：C

설명：
Solution (C) is the best option to meet the developer's requirements. The AWS SAM CLI tool provides an easy way to generate sample events and invoke Lambda functions locally. The solution is also easy to document and integrate into the CI/CD pipeline.

질문 # 143
A developer has observed an increase in bugs in the AWS Lambda functions that a development team has deployed in its Node is application. To minimize these bugs, the developer wants to impendent automated testing of Lambda functions in an environment that Closely simulates the Lambda environment.
The developer needs to give other developers the ability to run the tests locally. The developer also needs to integrate the tests into the team's continuous integration and continuous delivery (Ct/CO) pipeline before the AWS Cloud Development Kit (AWS COK) deployment.
Which solution will meet these requirements?

A. Install a unit testing framework that reproduces the Lambda execution environment. Create sample events based on the Lambda Documentation Invoke the handler function by using a unit testing framework. Check the response Document how to run the unit testing framework for the other developers on the team. Update the OCD pipeline to run the unit testing framework.
B. Create sample events based on the Lambda documentation. Create a Docker container from the Node is base image to invoke the Lambda functions. Check the response Document how to run the Docker container for the more developers on the team update the CI/CD pipeline to run the Docker container.
C. Install the AWS Serverless Application Model (AWS SAW) CLI tool Use the Sam local generate-event command to generate sample events for me automated tests. Create automated test scripts that use the Sam local invoke command to invoke the Lambda functions. Check the response Document the test scripts tor the other developers on the team Update the CI/CD pipeline to run the test scripts.
D. Create sample events based on the Lambda documentation. Create automated test scripts that use the cdk local invoke command to invoke the Lambda functions. Check the response Document the test scripts for the other developers on the team Update the CI/CD pipeline to run the test scripts.

정답：C

설명：
This solution will meet the requirements by using AWS SAM CLI tool, which is a command line tool that lets developers locally build, test, debug, and deploy serverless applications defined by AWS SAM templates. The developer can use sam local generate-event command to generate sample events for different event sources such as API Gateway or S3. The developer can create automated test scripts that use sam local invoke command to invoke Lambda functions locally in an environment that closely simulates Lambda environment.
The developer can check the response from Lambda functions and document how to run the test scripts for other developers on the team. The developer can also update CI/CD pipeline to run these test scripts before deploying with AWS CDK. Option A is not optimal because it will use cdk local invoke command, which does not exist in AWS CDK CLI tool. Option B is not optimal because it will use a unit testing framework that reproduces Lambda execution environment, which may not be accurate or consistent with Lambda environment. Option D is not optimal because it will create a Docker container from Node.js base image to invoke Lambda functions, which may introduce additional overhead and complexity for creating and running Docker containers.

질문 # 144
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. Amazon CloudWatch
B. Amazon DynamoDB
C. AWS CloudTrail
D. Amazon S3

정답：A

설명：
Lambda automatically integrates with CloudWatch Logs and pushes all logs from your code to a CloudWatch Logs group associated with a Lambda function.

질문 # 145
A developer is troubleshooting an application mat uses Amazon DynamoDB in the uswest-2 Region. The application is deployed to an Amazon EC2 instance. The application requires read-only permissions to a table that is named Cars The EC2 instance has an attached IAM role that contains the following IAM policy.

When the application tries to read from the Cars table, an Access Denied error occurs.
How can the developer resolve this error?

A. Create a trust policy that specifies the EC2 service principal. Associate the role with the policy.
B. Modify the IAM policy to include the dynamodb * action
C. Modify the IAM policy resource to be "arn aws dynamo* us-west-2 account-id table/*"
D. Create a trust relationship between the role and dynamodb Amazonas com.

질문 # 146
A social media company is designing a platform that allows users to upload data, which is stored in Amazon S3. Users can upload data encrypted with a public key. The company wants to ensure that only the company can decrypt the uploaded content using an asymmetric encryption key. The data must always be encrypted in transit and at rest.
Options:

A. Use server-side encryption with customer-provided encryption keys (SSE-C) to encrypt the data.
B. Use client-side encryption with a customer-managed encryption key to encrypt the data.
C. Use client-side encryption with a data key to encrypt the data.
D. Use server-side encryption with Amazon S3 managed keys (SSE-S3) to encrypt the data.

정답：B

설명：
Step 1: Problem Understanding
* Asymmetric Encryption Requirement: Users encrypt data with a public key, and only the company can decrypt it using a private key.
* Data Encryption at Rest and In Transit: The data must be encrypted during upload (in transit) and when stored in Amazon S3 (at rest).
Step 2: Solution Analysis
* Option A: Server-side encryption with Amazon S3 managed keys (SSE-S3).
* Amazon S3 manages the encryption and decryption keys.
* This does not meet the requirement for asymmetric encryption, where the company uses a private key.
* Not suitable.
* Option B: Server-side encryption with customer-provided keys (SSE-C).
* Requires the user to supply encryption keys during the upload process.
* Does not align with the asymmetric encryption requirement.
* Not suitable.
* Option C: Client-side encryption with a data key.
* Data key encryption is symmetric, not asymmetric.
* Does not satisfy the requirement for a public-private key pair.
* Not suitable.
* Option D: Client-side encryption with a customer-managed encryption key.
* Data is encrypted on the client side using the public key.
* Only the company can decrypt the data using the corresponding private key.
* Data remains encrypted during upload (in transit) and in S3 (at rest).
* Correct option.
Step 3: Implementation Steps for Option D
* Generate Key Pair:
* The company generates an RSA key pair (public/private) for encryption and decryption.
* Encrypt Data on Client Side:
* Use the public key to encrypt the data before uploading to S3.
* S3 Upload:
* Upload the encrypted data to S3 over an HTTPS connection.
* Decrypt Data on the Server:
* Use the private key to decrypt data when needed.
