質問 # 913
A company needs to invoke an AWS Step Functions workflow each time an Amazon EC2 instance state changes to RUNNING.
Which AWS service can the company use to meet this requirement?
正解：C
解説：
Amazon EventBridge Overview:
EventBridge is a serverless event bus that enables applications to react to changes in AWS resources.
It supports routing events such as EC2 state changes to various targets, including AWS Step Functions.
How EventBridge Meets the Requirement:
EventBridge can capture the EC2 instance state change event and trigger the execution of a Step Functions workflow.
The integration is seamless and supports workflows triggered by multiple event sources.
Why Other Options Are Incorrect:
A . Amazon SageMaker:Used for building, training, and deploying machine learning models; not related to event triggers.
B . Amazon Connect:A cloud-based contact center service; unrelated to event triggers.
D . AWS Fargate:A compute engine for containers; does not manage events or invoke workflows.

質問 # 914
A user wants to invoke an AWS Lambda function when an Amazon EC2 instance enters the "stopping" state.
Which AWS service is appropriate for this use case?
正解：B
解説：
Amazon EventBridge (formerly CloudWatch Events) allows users to respond to changes in the state of AWS resources. It can be configured to invoke an AWS Lambda function when an EC2 instance enters the "stopping" state, providing a serverless way to automate responses to changes in EC2 instance states. AWS Config, SNS, and CloudFormation do not provide direct triggering for specific instance state changes.
質問 # 915
Which action is a security best practice for access to sensitive data that is stored in an Amazon S3 bucket?
正解：D
解説：
* Understanding IAM Roles: IAM (Identity and Access Management) roles in AWS are designed to delegate access permissions without sharing long-term security credentials. This means applications and services can use temporary security credentials, which enhances security.
* Why IAM Roles are Best Practice:
* Least Privilege Principle: By using IAM roles, you can ensure that applications only have the minimum permissions they need to function, reducing the risk of unauthorized access.
* Temporary Credentials: Roles provide temporary security credentials, which reduce the risk if they are compromised compared to long-term access keys.
* Automated Rotation: Temporary credentials automatically expire and are rotated, which means you don't have to manage the rotation manually.
* How to Implement IAM Roles:
* Create an IAM Role: In the AWS Management Console, navigate to IAM, and create a new role.
Choose the type of trusted entity (e.g., EC2, Lambda).
* Attach Policies: Attach the necessary policies to the role that define the permissions for accessing the S3 bucket.
* Assign Role to Service: Attach the IAM role to your EC2 instances, Lambda functions, or other AWS services that need to access the S3 bucket.
* Use AWS SDKs: When accessing S3 from your application, use the AWS SDKs to automatically assume the IAM role and obtain temporary credentials.

Which AWS service should the company use to ingest and display this information?
正解：C

Amazon QuickSight enables you to ingest, analyze, and display data from various sources, such as AWS Cost and Usage Reports, Amazon S3, Amazon Athena, Amazon Redshift, and Amazon RDS. You can use Amazon QuickSight to create interactive dashboards and charts that show insights and trends from your data. You can also share your dashboards and charts with other users or embed them into your applications.
質問 # 917
A company runs its production workload in the AWS Cloud. The company needs to choose one of the AWS Support Plans.
Which of the AWS Support Plans will meet these requirements at the LOWEST cost?
正解：B
解説：
The AWS Developer Support plan is the lowest-cost AWS Support plan that provides basic guidance and technical support for running production workloads. It offers 24/7 access to AWS customer service, documentation, whitepapers, and access to a limited set of Trusted Advisor checks. This plan is ideal for non- critical workloads or early development phases but provides lower levels of support compared to the Business, Enterprise On-Ramp, and Enterprise plans.
* B. Enterprise On-Ramp: Incorrect, as it is a higher-cost support plan designed for production workloads needing more guidance and technical support.
* C. Enterprise: Incorrect, as it is the most expensive support plan, providing a Technical Account Manager and other premium support features.
* D. Business: Incorrect, as it provides comprehensive support for production workloads but is more expensive than the Developer plan.
