Amazon AWS Certified CloudOps Engineer - Associate 認定 SOA-C03 試験問題 (Q106-Q111):質問 # 106
A company hosts a web application on an Amazon EC2 instance. The web server logs are published to Amazon CloudWatch Logs. The log events have the same structure and include the HTTP response codes that are associated with the user requests. The company needs to monitor the number of times that the web server returns an HTTP 404 response.
What is the MOST operationally efficient solution that meets these requirements?
  • A. Create an AWS Lambda function that runs a CloudWatch Logs Insights query that counts the number of 404 codes in the log events during the past hour.
  • B. Create a CloudWatch Logs metric filter that counts the number of times that the web server returns an HTTP 404 response.
  • C. Create a script that runs a CloudWatch Logs Insights query that counts the number of 404 codes in the log events during the past hour.
  • D. Create a CloudWatch Logs subscription filter that counts the number of times that the web server returns an HTTP 404 response.
正解：B
解説：
A CloudWatch Logs metric filter can automatically scan log events in real time and extract specific patterns - such as HTTP 404 response codes - to publish custom metrics. This provides continuous, automated monitoring without the need for scheduled queries or external scripts, making it the most operationally efficient and scalable solution.

質問 # 107
A CloudOps engineer needs to build an event infrastructure for a set of custom application- specific events. The events must be sent to an AWS Lambda function for processing. The CloudOps engineer must record the events to replay later by event type or event time.
Which solution will meet these requirements?
  • A. Create an Amazon EventBridge custom event bus. Create an archive on the custom event bus.
    Create a rule to send the custom events to the Lambda function.
  • B. Create an archive on the Amazon EventBridge default event bus. Create an EventBridge pipe to ingest the custom events and to save the custom events in the archive. Create a rule to send the custom events to the Lambda function.
  • C. Create a log group in Amazon CloudWatch Logs. Create an Amazon EventBridge rule to send the custom events to the Lambda function and to the log group.
  • D. Create an archive on the Amazon EventBridge default event bus. Use pattern matching to record the custom events. Create a rule to send the custom events to the Lambda function.
正解：A
解説：
A custom EventBridge event bus is the correct choice for handling application-specific events.
You can define an archive on that custom event bus to record and later replay events by event type or timestamp. Creating an EventBridge rule to send events to a Lambda function ensures real-time processing while maintaining full replay capability, making this the most flexible and operationally efficient solution.

質問 # 108
A company that uses AWS Organizations recently implemented AWS Control Tower. The company now needs to centralize identity management. A CloudOps engineer must federate AWS IAM Identity Center with an external SAML 2.0 identity provider (IdP) to centrally manage access to all AWS accounts and cloud applications.
Which prerequisites must the CloudOps engineer have so that the CloudOps engineer can connect to the external IdP? (Select TWO.)
  • A. Root access to the management account
  • B. The IP address of the IdP
  • C. The IdP metadata, including the public X.509 certificate
  • D. Administrative permissions to the member accounts of the organization
  • E. A copy of the IAM Identity Center SAML metadata
正解：C、E
解説：
According to the AWS Cloud Operations and Identity Management documentation, when configuring federation between IAM Identity Center (formerly AWS SSO) and an external SAML
2.0 identity provider, two key prerequisites are required:
The IAM Identity Center SAML metadata file -- This is uploaded to the external IdP to establish trust, define SAML endpoints, and enable identity federation.
The IdP metadata (including the public X.509 certificate) -- This information is imported into IAM Identity Center to validate authentication assertions and encryption signatures.
IAM Identity Center and the IdP exchange this metadata to mutually establish secure, bidirectional federation.
Network-level details such as IP addresses (Option C) are unnecessary. Root access (Option D) or permissions to member accounts (Option E) are not required; only Control Tower or IAM administrative permissions in the management account are needed for setup.
Thus, the correct answer is A and B -- the SAML metadata from both sides is required for federation.

質問 # 109
A company runs an application that logs user data to an Amazon CloudWatch Logs log group.
The company discovers that personal information the application has logged is visible in plain text in the CloudWatch logs.
The company needs a solution to redact personal information in the logs by default. Unredacted information must be available only to the company's security team. Which solution will meet these requirements?
  • A. Create an OpenSearch domain. Create an AWS Glue workflow that runs a Detect PII transform job and streams the output to the OpenSearch domain. Configure the CloudWatch log group to stream the logs to AWS Glue. Modify the OpenSearch domain access policy to allow only the security team to access the domain.
  • B. Create a customer managed AWS KMS key. Configure the KMS key policy to allow only the security team to perform decrypt operations. Associate the KMS key with the application log group.
  • C. Create an Amazon S3 bucket. Create an export task from appropriate log groups in CloudWatch.
    Export the logs to the S3 bucket. Configure an Amazon Macie scan to discover personal data in the S3 bucket. Invoke an AWS Lambda function to move identified personal data to a second S3 bucket.
    Update the S3 bucket policies to grant only the security team access to both buckets.
  • D. Create an Amazon CloudWatch data protection policy for the application log group. Configure data identifiers for the types of personal information that the application logs. Ensure that the security team has permission to call the unmask API operation on the application log group.
正解：D
解説：
CloudWatch Logs data protection provides native redaction/masking of sensitive data at ingestion and query. AWS documentation states it can "detect and protect sensitive data in logs" using data identifiers, and that authorized users can "use the unmask action to view the original data." Creating a data protection policy on the log group masks PII by default for all viewers, satisfying the requirement to redact personal information. Granting only the security team permission to invoke the unmask API operation ensures that unredacted content is restricted. Option B (KMS) encrypts at rest but does not redact fields; encryption alone does not prevent plaintext visibility to authorized readers. Options A and D add complexity and latency, move data out of CloudWatch, and do not provide default inline redaction/unmask controls in CloudWatch itself. Therefore, the CloudOps-aligned, managed solution is to use CloudWatch Logs data protection with appropriate data identifiers and unmask permissions limited to the security team.

質問 # 110
A company hosts an FTP server on EC2 instances. AWS Security Hub sends findings to Amazon EventBridge when the FTP port becomes publicly exposed in attached security groups.
A CloudOps engineer needs an automated, event-driven remediation solution to remove public access from security groups.
Which solution will meet these requirements?
  • A. Configure the existing EventBridge event to invoke an AWS Lambda function. Configure the function to remove the security group rule that allows public access.
  • B. Create a cron job for the FTP server to invoke an AWS Lambda function. Configure the Lambda function to modify the security group of the identified EC2 instances and to remove the instances that allow public access.
  • C. Configure the existing EventBridge event to stop the EC2 instances that have the exposed port.
  • D. Create a cron job for the FTP server that invokes an AWS Lambda function. Configure the Lambda function to modify the server to use SFTP instead of FTP.
正解：A
解説：
Per the AWS Cloud Operations and Security Automation documentation, Security Hub integrates with Amazon EventBridge to publish findings in real time. These events can trigger automated responses using AWS Lambda functions or AWS Systems Manager Automation runbooks.
In this scenario, the correct CloudOps approach is to configure the existing EventBridge rule to invoke a Lambda function that inspects the event payload, identifies the affected security group, and removes the offending inbound rule (e.g., port 21 open to 0.0.0.0/0).
This event-driven remediation provides continuous compliance and eliminates manual intervention. Cron jobs (Options B and C) contradict event-driven design and add operational overhead. Stopping instances (Option A) doesn't address the root cause - the insecure security group.
Thus, Option D aligns with AWS best practices for automated security remediation through EventBridge and Lambda.
