Amazon SOA-C03 Online Questions & Answers

• Question 261:

  A company manages a set of AWS accounts by using AWS Organizations. The company's security team wants to use a native AWS service to regularly scan all AWS accounts against the Center for Internet Security (CIS) AWS Foundations Benchmark.

  What is the MOST operationally efficient way to meet these requirements?

  A. Designate a central security account as the AWS Security Hub administrator account. Use scripts to invite and accept member accounts.
  B. Run the CIS AWS Foundations Benchmark by using Amazon Inspector.
  C. Designate a central security account as the Amazon GuardDuty administrator account and configure CIS scans.
  D. Designate an AWS Security Hub administrator account, automatically enroll new organization accounts, and enable CIS AWS Foundations Benchmark.
  D. Designate an AWS Security Hub administrator account, automatically enroll new organization accounts, and enable CIS AWS Foundations Benchmark.

  ---

  Explanation

  AWS Security Hub is the native AWS service that provides continuous compliance checks against security standards, including the CIS AWS Foundations Benchmark. When integrated with AWS Organizations, Security Hub can automatically enroll existing and newly created accounts, eliminating manual invitations and scripts.

  By designating a Security Hub administrator account and enabling automatic account onboarding, the organization ensures consistent security posture monitoring across all accounts. CIS benchmark checks are run continuously, and findings are aggregated centrally, simplifying governance and remediation workflows.

  Amazon Inspector focuses on vulnerability scanning for EC2, container images, and Lambda functions-- not CIS compliance. GuardDuty is a threat detection service and does not run CIS benchmarks.

  Therefore, using AWS Security Hub with automatic organization-wide enrollment is the most efficient solution.

• Question 262:

  A company needs to ensure that production data is recoverable after accidental deletion.

  The workload uses Amazon EFS for shared storage. The CloudOps engineer wants a managed backup solution that supports centralized policies and restores.

  Which solution will meet these requirements?

  A. Use AWS Backup to create backup plans for EFS file systems and define retention policies.
  B. Enable S3 Cross-Region Replication for EFS.
  C. Take EBS snapshots of the EC2 instances that mount EFS.
  D. Enable Amazon Inspector to scan EFS and generate restore points.
  A. Use AWS Backup to create backup plans for EFS file systems and define retention policies.

  Explanation

  AWS Backup is the managed service for centrally configuring backup policies, scheduling, retention, and restore workflows across supported AWS services, including Amazon EFS. By creating backup plans, vaults, and lifecycle/retention policies, the CloudOps engineer can meet recoverability requirements with minimal operational overhead and consistent governance. Restores can be initiated through AWS Backup, and policies can be standardized across environments.

  S3 replication is not applicable to EFS. EBS snapshots capture block volumes attached to instances, not EFS file system state. Inspector does not provide backup/restore functionality.

• Question 263:

  An AWS Lambda function is intermittently failing several times a day. A CloudOps engineer must find out how often this error occurred in the last 7 days.

  Which action will meet this requirement in the MOST operationally efficient manner?

  A. Use Amazon Athena to query the Amazon CloudWatch logs that are associated with the Lambda function.
  B. Use Amazon Athena to query the AWS CloudTrail logs that are associated with the Lambda function.
  C. Use Amazon CloudWatch Logs Insights to query the associated Lambda function logs.
  D. Use Amazon OpenSearch Service to stream the Amazon CloudWatch logs for the Lambda function.
  C. Use Amazon CloudWatch Logs Insights to query the associated Lambda function logs.

  ---

  Explanation

  The AWS Cloud Operations and Monitoring documentation states that Amazon CloudWatch Logs Insights provides a purpose-built query engine for analyzing and visualizing log data directly within CloudWatch. For Lambda, all invocation results (including errors) are automatically logged to CloudWatch Logs. By querying these logs with CloudWatch Logs Insights, the CloudOps engineer can efficiently count the number of "ERROR" or "Exception" occurrences over the past 7 days using simple SQL-like commands. This method is serverless, cost-efficient, and real-time. Athena (Options A and B) would require exporting data to Amazon S3, and OpenSearch (Option D) adds unnecessary operational complexity.

  Thus, Option C provides the most efficient and native AWS CloudOps approach for rapid Lambda error analysis.
