質問 # 212
A company is using AWS CloudTrail and Amazon CloudWatch to monitor resources in an AWS account.
The company's developers have been using an IAM role in the account for the last 3 months.
A security engineer needs to refine the customer managed IAM policy attached to the role to ensure that the role provides least privilege access.
Which solution will meet this requirement with the LEAST effort?
正解：C
解説：
AWS IAM Access Analyzer policy generation is specifically designed to help security engineers generate least-privilege IAM policies based on actual usage recorded in AWS CloudTrail. According to the AWS Certified Security - Specialty documentation, policy generation analyzes historical CloudTrail data to identify the exact API actions and resources that a role has accessed over a specified time period.
Because the role has been actively used for three months, there is sufficient CloudTrail data for IAM Access Analyzer to generate a refined customer managed policy automatically. This significantly reduces manual effort and eliminates the need to analyze logs or infer permissions. The generated policy can be reviewed and attached directly to the role, ensuring least privilege access with minimal engineering effort.
Option B only validates existing policies for security warnings and does not reduce permissions. Option C requires manual analysis of CloudWatch logs, which is time-consuming and error-prone. Option D does not analyze real usage and cannot generate role-specific least privilege policies.
AWS documentation explicitly recommends IAM Access Analyzer policy generation as the fastest and most accurate method to refine IAM permissions based on observed behavior.

A security engineer configured VPC Flow Logs to publish to Amazon CloudWatch Logs. After 10 minutes, no logs appear. The issue is isolated to the IAM role associated with VPC Flow Logs.
What could be the reason?
正解：D
解説：
VPC Flow Logs require an IAM role that CloudWatch Logs can use to publish flow log records. AWS documentation and AWS Certified Security - Specialty materials explain that the VPC Flow Logs service must be able to assume the IAM role through its trust policy. The trust relationship must include the service principal vpc-flow-logs.amazonaws.com. If the trust policy does not allow this principal to assume the role, flow logs cannot be delivered and no records will appear in the CloudWatch Logs log group even when traffic exists. logs:GetLogEvents is not required for delivery; it is used for reading logs. The security engineer's ability to assume the role is not relevant because the service, not the engineer, assumes it. Tagging permissions are not required for basic log delivery. Therefore, the most likely cause is an incorrect trust policy that prevents the VPC Flow Logs service principal from assuming the role.

質問 # 214
A company uses an organization in AWS Organizations to manage multiple AWS accounts. The company wants to centrally give users the ability to access Amazon Q Developer.
Which solution will meet this requirement?
正解：C
解説：
For centralized, organization-wide user access to AWS services and supported applications, AWS best practice is to useAWS IAM Identity Center(successor to AWS SSO). IAM Identity Center provides a single place to manage workforce identities, permission sets, and account assignments across AWS Organizations.
Amazon Q Developer is integrated for centralized access using IAM Identity Center, where you can assign the relevant permissions to users and groups and enable access consistently across multiple AWS accounts.
Setting Amazon Q Developer up as anAWS managed applicationaligns with IAM Identity Center's model for centrally provisioning and controlling access with minimal operational overhead.
Amazon Cognito is primarily intended forcustomer identity and application sign-up/sign-inscenarios, not for workforce access to AWS managed developer tools across multiple AWS accounts. "Identity pools" are a Cognito concept for exchanging identities for AWS credentials, which adds unnecessary complexity and is not the standard approach for centrally granting employees access to Amazon Q Developer in an organization.
Therefore, enabling IAM Identity Center and configuring Amazon Q Developer as an AWS managed application is the correct solution.
質問 # 215
A company runs an application on an Amazon EC2 instance. The application generates invoices and stores them in an Amazon S3 bucket. The instance profile that is attached to the instance has appropriate access to the S3 bucket. The company needs to share each invoice with multiple clients that do not have AWS credentials. Each client must be able to download only the client's own invoices. Clients must download their invoices within 1 hour of invoice creation. Clients must use only temporary credentials to access the company's AWS resources.
Which additional step will meet these requirements?
正解：D
解説：
Amazon S3 pre-signed URLs grant temporary access based on the permissions of the principal that generates them. AWS Certified Security - Specialty documentation explains that fine-grained authorization can be enforced by combining pre-signed URLs with IAM policy conditions.
By tagging each invoice object with a client identifier and adding a condition to the EC2 instance role policy using s3:ResourceTag/ClientId, the role can generate pre-signed URLs only for objects associated with a specific client. This ensures that each client can access only their own invoices, even though the URLs are temporary and unauthenticated.
Option A over-permissions clients. Option C is unnecessary because instance profiles already use temporary credentials. Option D violates AWS best practices by using long-term credentials.
AWS recommends resource tagging with IAM policy conditions for scalable, secure access control.

質問 # 216
A company runs critical workloads in an on-premises data center. The company wants to implement an AWS based disaster recovery (DR) solution that will achieve an RTO of less than 1 hour. The company needs to continuously replicate physical and virtual servers. The company must optimize costs for data storage and bandwidth usage. The DR solution must be automated.
Which solution will meet these requirements?
正解：B
解説：
AWS Elastic Disaster Recovery (AWS DRS)is purpose-built for continuously replicatingphysical and virtual serversinto AWS with low RTO/RPO. It uses lightweight replication agents to stream block-level changes to a low-coststaging areain AWS, which helps optimize storage costs (only the staging resources run continuously) and reduces bandwidth usage through efficient replication mechanisms. In a disaster or test, AWS DRS can automatically launch recovery instances in AWS based on a defined blueprint (instance types, networking, security groups), enabling rapid failover workflows that commonly meetsub-hour RTOobjectives.
Option A is not the intended service model: AWS Backup protects AWS-native resources and does not
"directly replicate" arbitrary on-prem servers as a continuous replication DR system. Option B (Storage Gateway Volume Gateway) can support backups of certain storage use cases via snapshots, but it is not a general continuous replication solution for diverse physical/virtual servers and may not meet the RTO requirement as directly as AWS DRS. Option D (Direct Connect + custom automation) can help with connectivity, but it does not provide continuous server replication by itself and would require significant custom engineering and ongoing operational effort.
Therefore, enabling AWS Elastic Disaster Recovery and configuring replication agents is the best automated, cost-optimized solution.
