질문 # 818
A developer wants to use an Amazon CloudFront distribution to deliver a web application to users. Users will access the application through the internet.
The developer needs to create an SSL/TLS certificate to use with the CloudFront distribution. The developer wants to minimize operational overhead by ensuring that the certificate is renewed automatically.
Which solution will meet these requirements?

A. Create a public certificate that uses email validation in AWS Certificate Manager (ACM).
B. Create a public certificate that uses DNS validation in IAM.
C. Create a public certificate that uses DNS validation in AWS Certificate Manager.
D. Import a certificate into IAM. Configure managed renewal for the certificate.

정답：C

설명：
Using AWS Certificate Manager (ACM) with DNS validation for a public certificate enables automatic renewal and is fully compatible with Amazon CloudFront. This approach minimizes operational overhead because ACM handles the entire lifecycle of the certificate, including renewals and deployment to CloudFront.

질문 # 819
A developer has an application that pushes files from an on-premises local server to an Amazon S3 bucket.
The application uses an AWS access key and a secret key that are stored on the server for authentication. The application calls AWS STS to assume a role with access to perform the S3 PUT operation to upload the file.
The developer is migrating the server to an Amazon EC2 instance. The EC2 instance is configured with an IAM instance profile in the same AWS account that owns the S3 bucket.
What is the MOST secure solution for the developer to use to migrate the automation code?

A. Remove the access key, the secret key, and the code that calls the STS AssumeRole operation. Create a new access key and secret key. Use the new keys to access the S3 bucket.
B. Remove the access key and the secret key. Use the STS AssumeRole operation to add permissions to access the S3 bucket.
C. Remove the code that calls the STS AssumeRole operation. Use the same access key and secret key from the server to access the S3 bucket.
D. Remove the access key, the secret key, and the code that calls the STS AssumeRole operation. Use an IAM instance profile role that grants access to the S3 bucket.

정답：D

설명：
The most secure approach on Amazon EC2 is to avoid long-term static credentials entirely and rely on IAM roles for Amazon EC2 (instance profiles). When an EC2 instance is associated with an instance profile, AWS automatically provides temporary security credentials to the instance through the instance metadata service (IMDS). The AWS SDK and CLI can retrieve and rotate these credentials automatically, eliminating the need to store an access key and secret key on disk. This reduces the risk of credential leakage and removes the operational burden of key rotation.
In this scenario, the EC2 instance is already configured with an IAM instance profile in the same account as the S3 bucket. Because the bucket is in the same account and the instance profile can be granted the required permissions, there is no security benefit to keeping a separate stored access key/secret key or performing an additional STS AssumeRole hop. The simplest and most secure design is to attach an IAM policy to the instance profile role that allows the required s3:PutObject (and any related actions such as s3:PutObjectAcl if needed) on the specific bucket/prefix. The application code can then call S3 directly using the AWS SDK, which will automatically use the instance profile credentials.
Option A continues to use long-lived static credentials stored on the server, which is less secure than instance profiles. Option D is the same problem with different keys: still long-lived credentials that must be protected and rotated. Option B removes stored keys but keeps an AssumeRole call; although AssumeRole uses temporary credentials, it adds complexity and is unnecessary here because the instance already has an IAM role and the S3 bucket is in the same account.
Therefore, the most secure solution is C: remove static keys and the AssumeRole code and use the instance profile role with least-privilege S3 permissions.

질문 # 820
Users are reporting errors in an application. The application consists of several microservices that are deployed on Amazon Elastic Container Service (Amazon ECS) with AWS Fargate.
Which combination of steps should a developer take to fix the errors? (Choose two.)

A. Instrument the application by using the AWS X-Ray SDK. Update the application to use the PutXrayTrace API call to communicate with the X-Ray API.
B. Deploy AWS X-Ray as a sidecar container to the microservices. Update the task role policy to allow access to the X-Ray API.
C. Instrument the ECS task to send the stdout and stderr output to Amazon CloudWatch Logs.Update the task role policy to allow the cloudwatch:PullLogs action.
D. Deploy AWS X-Ray as a daemonset to the Fargate cluster. Update the service role policy to allow access to the X-Ray API.
E. Instrument the application by using the AWS X-Ray SDK. Update the application to communicate with the X-Ray daemon.

정답：B,E

질문 # 821
A company has an application that uses Amazon Cognito user pools as an identity provider. The company must secure access to user records. The company has set up multi-factor authentication (MFA). The company also wants to send a login activity notification by email every time a user logs in.
What is the MOST operationally efficient solution that meets this requirement?

A. Create an AWS Lambda function that uses Amazon Simple Email Service (Amazon SES) to send the email notification. Create an Amazon CloudWatch Logs log subscription filter to invoke the function based on the login status.
B. Create an AWS Lambda function that uses Amazon Simple Email Service (Amazon SES) to send the email notification. Add an Amazon Cognito post authentication Lambda trigger for the function.
C. Configure Amazon Cognito to stream all logs to Amazon Kinesis Data Firehose. Create an AWS Lambda function to process the streamed logs and to send the email notification based on the login status of each user.
D. Create an AWS Lambda function that uses Amazon Simple Email Service (Amazon SES) to send the email notification. Add an Amazon API Gateway API to invoke the function. Call the API from the client side when login confirmation is received.

정답：B

설명：
Amazon Cognito user pools support Lambda triggers, which are custom functions that can be executed at various stages of the user pool workflow. A post authentication Lambda trigger can be used to perform custom actions after a user is authenticated, such as sending an email notification. Amazon SES is a cloud-based email sending service that can be used to send transactional or marketing emails. A Lambda function can use the Amazon SES API to send an email to the user's email address after the user logs in successfully. Reference: Post authentication Lambda trigger

질문 # 822
A company regularly receives route status updates from its delivery trucks as events in Amazon EventBridge.
The company is building an API-based application in a VPC that will consume and process the events to create a delivery status dashboard. The API application must not be available by using public IP addresses because of security and compliance requirements.
How should the company send events from EventBridge to the API application?

A. Create an AWS Lambda function that runs in the same VPC as the API application. Configure the function as an EventBridge target. Use the function to send events to the API.
B. Create an internet-facing Application Load Balancer (ALB) in front of the API application. Associate a security group with rules that block access from all external sources except for EventBridge. Configure the ALB as an EventBridge target.
C. Create an internet-facing Network Load Balancer (NLB) in front of the API application. Associate a security group with rules that block access from all external sources except for EventBridge. Configure the NLB as an EventBridge target.
D. Use the application API endpoint in the VPC as a target for EventBridge. Send events directly to the application API endpoint from EventBridge.

정답：A

설명：
Comprehensive Detailed Explanation with all AWS References
* Why Option A is Correct:Running an AWS Lambda function within the same VPC ensures secure communication without exposing the API application to public IP addresses. The Lambda function can serve as a secure EventBridge target to send events to the API.
* Why Other Options are Incorrect:
* Option B & C: Internet-facing load balancers expose public IP addresses, which violates compliance requirements.
* Option D: EventBridge cannot directly target an endpoint within a private VPC without intermediary services like Lambda.
* AWS Documentation References:
* EventBridge Targets
