383. Frage
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:
Antwort: C
Begründung:
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.

384. Frage
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?
Antwort: B
Begründung:
Explanation
The AWS Serverless Application Model Command Line Interface (AWS SAM CLI) is a command-line tool for local development and testing of Serverless applications3. The sam local generate-event command of AWS SAM CLI generates sample events for automated tests3. The sam local invoke command is used to invoke Lambda functions3. Therefore, option C is correct.
385. Frage
A developer is adding new functionality to an existing application that was initially built by using the AWS CDK. The developer creates a new Lambda function and needs to deploy it. Which AWS CDK command must the developer use to prepare the new Lambda function for deployment?
Antwort: B
Begründung:
The cdk synth command synthesizes the AWS CDK app into an AWS CloudFormation template, which includes the new Lambda function definition. This step prepares the resources for deployment by generating the template that will be deployed to AWS.
386. Frage
A company is planning to securely manage one-time fixed license keys in AWS. The company's development team needs to access the license keys in automaton scripts that run in Amazon EC2 instances and in AWS CloudFormation stacks.
Which solution will meet these requirements MOST cost-effectively?
Antwort: A
387. Frage
A travel booking company is developing a web application that gives users the ability to search for flights and hotels and to make reservations. The web application uses a relational database and third-party /VPIs.
The company needs a solution to securely manage database credentials and API keys. The solution must not negatively affect the performance of the application.
Which solution will meet these requirements?
Antwort: D
Begründung:
Storing credentials in AWS Systems Manager Parameter Store as secure strings encrypted with AWS KMS provides a secure, scalable, and low-latency method to manage secrets such as database credentials and API keys. It integrates well with applications and does not impact performance, making it ideal for production workloads.
