질문 # 615
A developer is creating a new batch application that will run on an Amazon EC2 instance. The application requires read access to an Amazon S3 bucket. The developer needs to follow security best practices to grant S3 read access to the application.
Which solution meets these requirements?

A. Add the permissions to an 1AM policy. Attach the policy to a user. Attach the user to the EC2 instance profile.
B. Add the permissions inline to an 1AM group. Attach the group to the EC2 instance profile.
C. Add the permissions to an 1AM policy. Use 1AM web identity federation to access the S3 bucket with the policy.
D. Add the permissions to an 1AM policy. Attach the policy to a role. Attach the role to the EC2 instance profile.

정답：D

설명：
Step 1: Understanding the Requirements
* Best Practices for Security:
* Minimize the use of hardcoded credentials or long-lived access keys.
* Use IAM roles for EC2 instances to securely grant permissions to applications running on the instance.
* Access Scope: The application needs read-only access to an S3 bucket.
Step 2: Solution Analysis
* Option A:
* Define an IAM policy with the required s3:GetObject permissions.
* Attach this policy to an IAM role.
* Assign the role to the EC2 instance profile.
* This approach follows security best practices by eliminating the need for static credentials and using temporary, scoped credentials provided by the instance profile.
* Correct option.
* Option B:
* IAM groups are used for organizing users, not for EC2 instances or instance profiles.
* Not suitable.
* Option C:
* IAM users are associated with specific individuals or applications and require static credentials.
* This violates security best practices for temporary credentials and roles.
* Not suitable.
* Option D:
* IAM web identity federation is used for applications that authenticate users via third-party identity providers.
* This is unnecessary for EC2 instances and does not align with the requirements.
* Not suitable.
Step 3: Implementation Steps
* Create an IAM Policy:
* Grant read-only access to the S3 bucket:
json
Copy code
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "s3:GetObject",
"Resource": "arn:aws:s3:::your-bucket-name/*"
}
]
}
* Attach the Policy to an IAM Role:
* Create an IAM role and attach the policy to the role.
* Associate the Role with the EC2 Instance:
* Attach the role to the instance profile used by the EC2 instance.
AWS Developer References:
* IAM Roles for Amazon EC2
* Amazon S3 Permissions Reference

질문 # 616
A developer is migrating a containerized application from an on-premises environment to an Amazon ECS cluster.
In the on-premises environment, the container uses a Docker file to store the application. Service dependency configurations such as databases, caches, and storage volumes are stored in a docker-compose.yml file.
Both files are located at the top level of the code base that the developer needs to containerize. When the developer deploys the code to Amazon ECS, the instructions from the Docker file are carried out. However, none of the configurations from docker-compose.yml are applied.
The developer needs to resolve the error and ensure the configurations are applied.

A. Update the service type of the ECS cluster to REPLICA, and redeploy the stack.
B. Store the file path for the docker-compose.yml file as a Docker label. Add the label to the ECS cluster's container details.
C. Create a namespace in the ECS cluster. Associate the docker-compose.yml file to the namespace.
D. Add the details from the docker-compose.yml file to an ECS task definition. Associate the task with the ECS cluster.

정답：D

설명：
Comprehensive Detailed Explanation with all AWS Reference
Why Option B is Correct:
Amazon ECS does not natively process docker-compose.yml files. Instead, the configurations from docker-compose.yml must be converted into ECS-compatible configurations within a task definition. Task definitions are the primary way to specify container configurations in ECS, including service dependencies like databases, caches, and volumes.
Steps to Resolve the Error:
Extract the configurations from the docker-compose.yml file.
Map the dependencies and settings to the appropriate ECS task definition fields.
Deploy the task definition to the ECS cluster.
Why Other Options are Incorrect:
Option A: Docker labels do not directly impact ECS task execution or integrate with ECS service configurations.
Option C: ECS namespaces do not exist as a feature.
Option D: Changing the service type to REPLICA does not resolve the issue of missing service dependency configurations.

질문 # 617
A developer has an application that runs in AWS Account A. The application must retrieve an AWS Secrets Manager secret that is encrypted by an AWS Key Management Service (AWS KMS) key from AWS Account B. The application's role has permissions to access the secret in Account B.
The developer must add a statement to the KMS key's key policy to allow the role in Account A to use the KMS key in Account B. The permissions must grant least privilege access to the role.
Which permissions will meet these requirements?

A. kms:*
B. kms:Decrypt and kms:DescribeKey
C. secretsmanager:DescribeSecret and secretsmanager:GetSecretValue
D. secretsmanager:*

정답：B

설명：
In this scenario, the application in AWS Account A needs to retrieve a secret that is encrypted using a KMS key in AWS Account B. The application's role has the necessary permissions to access the secret in Account B (via Secrets Manager). However, since the secret is encrypted using KMS, the role also needs the appropriate permissions on the KMS key in Account B to decrypt the secret.
kms:Decrypt: This permission is required to decrypt data that is encrypted with a specific KMS key. In this case, the application needs the ability to decrypt the secret that is stored in Secrets Manager and encrypted with the KMS key in Account B.
kms:DescribeKey: This permission allows the role to describe the KMS key, which can be useful for getting information about the key, such as its status. However, for the specific use case of accessing and decrypting the secret, this permission is sufficient.
Together, these two permissions--kms:Decrypt and kms:DescribeKey--ensure that the role can perform the necessary operations (decryption) on the KMS key while following the principle of least privilege.

질문 # 618
A developer maintains an Amazon API Gateway REST API. Customers use the API through a frontend UI and Amazon Cognito authentication.
The developer has a new version of the API that contains new endpoints and backward-incompatible interface changes. The developer needs to provide beta access to other developers on the team without affecting customers.
Which solution will meet these requirements with the LEAST operational overhead?

A. Implement a query parameter in the API application code that determines which code version to call.
B. Define a new API Gateway API that points to the new API application code. Instruct the other developers to point the endpoints to the new API.
C. Specify new API Gateway endpoints for the API endpoints that the developer wants to add.
D. Define a development stage on the API Gateway API. Instruct the other developers to point the endpoints to the development stage.

정답：D

질문 # 619
A developer is building an ecommerce application that uses multiple AWS Lambda functions. Each function performs a specific step in a customer order workflow, such as order processing and inventory management.
The developer must ensure that the Lambda functions run in a specific order.
Which solution will meet this requirement with the LEAST operational overhead?

A. Configure an Amazon Simple Queue Service (Amazon SQS) queue to contain messages about each step a function must perform. Configure the Lambda functions to run sequentially based on the order of messages in the SQS queue.
B. Configure an AWS Step Functions state machine to invoke the Lambda functions in a specific order.
C. Configure Amazon EventBridge Scheduler schedules to invoke the Lambda functions in a specific order.
D. Configure an Amazon Simple Notification Service (Amazon SNS) topic to contain notifications about each step a function must perform. Subscribe the Lambda functions to the SNS topic. Use subscription filters based on the step each function must perform.

정답：B

설명：
The requirement here is to ensure that Lambda functions are executed in a specific order. AWS Step Functions is a low-code workflow orchestration service that enables you to sequence AWS services, such as AWS Lambda, into workflows. It is purpose-built for situations like this, where different steps need to be executed in a strict sequence.
* AWS Step Functions: Step Functions allows developers to design workflows as state machines, where each state corresponds to a particular function. In this case, the developer can create a Step Functions state machine where each step (order processing, inventory management, etc.) is represented by a Lambda function.
* Operational Overhead: Step Functions have very low operational overhead because it natively handles retries, error handling, and function sequencing.
* Alternatives:
* Amazon SQS (Option A): While SQS can manage message ordering, it requires more manual handling of each step and the logic to sequentially invoke the Lambda functions.
* Amazon SNS (Option B): SNS is a pub/sub service and is not designed to handle sequences of Lambda executions.
* EventBridge (Option D): EventBridge Scheduler allows you to invoke Lambda functions based on scheduled times, but it doesn't directly support sequencing based on workflow logic.
Therefore, AWS Step Functions is the most appropriate solution due to its native orchestration capabilities and minimal operational complexity.
