質問 # 204
A company has hundreds of AWS accounts in an organization in AWS Organizations. The company operates out of a single AWS Region. The company has a dedicated security tooling AWS account in the organization. The security tooling account is configured as the organization's delegated administrator for Amazon GuardDuty and AWS Security Hub. The company has configured the environment to automatically enable GuardDuty and Security Hub for existing AWS accounts and new AWS accounts.
The company is performing control tests on specific GuardDuty findings to make sure that the company's security team can detect and respond to security events. The security team launched an Amazon EC2 instance and attempted to run DNS requests against a test domain,example.com, to generate a DNS finding. However, the GuardDuty finding was never created in the Security Hub delegated administrator account.
Why was the finding not created in the Security Hub delegated administrator account?
正解：B
解説：
GuardDuty's DNS-related detections depend on GuardDuty being able to observeDNS query behaviorthrough AWS-provided DNS resolution paths in the VPC. If a VPC is configured to use acustom DNS resolvervia DHCP options (for example, an OpenDNS resolver) instead of the AmazonProvidedDNS resolver, DNS queries may bypass the visibility path GuardDuty relies on for DNS analysis and pattern detection. In that case, the test traffic (queries to example.com) might not be evaluated by GuardDuty's DNS finding logic, so no DNS finding is generated--and therefore nothing is forwarded into Security Hub.
質問 # 205
A company needs to migrate several applications to AWS. This will require storing more than
5,000 credentials. To meet compliance requirements, the company will use its existing password management system for key rotation, auditing, and integration with third-party secrets containers.
The company has a limited budget and is seeking the most cost-effective solution that is still secure.
How should the company accomplish this at the LOWEST cost?
正解：D
質問 # 206
A company uses several AWS CloudFormation stacks to handle the deployment of a suite of applications.
The leader of the company's application development team notices that the stack deployments fail with permission errors when some team members try to deploy the stacks. However, other team members can deploy the stacks successfully.
The team members access the account by assuming a role that has a specific set of permissions. All team members have permissions to perform operations on the stacks.
Which combination of steps will ensure consistent deployment of the stacksMOST securely? (Select THREE.)
正解：A、E、F
解説：
AWS CloudFormation supports the use of aservice role, which allows CloudFormation to assume a dedicated IAM role to create and manage resources on behalf of users. According to the AWS Certified Security - Specialty Study Guide, using a service role is themost secure and consistent wayto ensure predictable stack deployments when users have varying permission sets.
By creating a service role with cloudformation.amazonaws.com as the trusted service principal (Option B), CloudFormation-not individual users-assumes responsibility for resource creation. Updating each stack to explicitly use this service role (Option E) ensures that all deployments use the same permission set, eliminating inconsistencies.
Granting the team members permission to pass the service role via iam:PassRole (Option F) is required so that CloudFormation can assume the role during stack operations. This approach adheres to the principle of least privilege and prevents users from gaining direct access to elevated permissions.
Composite principals (Option A) are unnecessary and insecure. Referencing stack ARNs (Option C) does not solve the root cause. While Option D reflects good policy design, it is implicit in creating the service role and is not a required standalone step.
AWS documentation clearly identifiesCloudFormation service roles combined with iam:PassRoleas best practice for secure, consistent infrastructure deployments.

質問 # 207
A security engineer is responding to an incident that is affecting an AWS account. The ID of the account is 123456789012. The attack created workloads that are distributed across multiple AWS Regions.
The security engineer contains the attack and removes all compute and storage resources from all affected Regions. However, the attacker also created an AWS KMS key. The key policy on the KMS key explicitly allows IAM principal kms:* permissions.
The key was scheduled to be deleted the previous day. However, the key is still enabled and usable.
The key has an ARN of arn:aws:kms:us-east-2:123456789012:key/mrk-
0bb0212cd9864fdea0dcamzo26efb5670.
The security engineer must delete the key as quickly as possible.
Which solution will meet this requirement?
正解：A
解説：
AWS KMS enforces a mandatory minimum waiting period of 7 days before a customer managed key can be deleted. According to AWS Certified Security - Specialty incident response guidance, no method exists to immediately delete a KMS key. The fastest possible deletion is achieved by scheduling deletion with the minimum 7-day waiting period.
In this scenario, although deletion was previously scheduled, the key remains enabled and usable. The most authoritative and reliable method to regain control and reissue deletion immediately is to use the AWS account root user, which has implicit permissions to manage KMS keys regardless of compromised IAM principals.
質問 # 208
A company begins to use AWS WAF after experiencing an increase in traffic to the company ' s public web applications. A security engineer needs to determine if the increase in traffic is because of application-layer attacks. The security engineer needs a solution to analyze AWS WAF traffic.
Which solution will meet this requirement?
正解：D
解説：
AWS WAF supportsWAF loggingas a dedicated feature that can deliver logs to destinations such as Amazon S3 (commonly via Kinesis Data Firehose). These logs contain rich request details (rule matches, action taken, headers, URI, source IP, etc.) that are essential for determining whether traffic spikes are due to application- layer attacks. For analysis with low operational overhead, storing logs inS3and querying them withAmazon Athenais a standard pattern. Usingpartition projectionfurther reduces administrative work by avoiding manual partition management and enabling efficient queries over time-based prefixes.
Options A and D incorrectly route WAF logs through CloudTrail; WAF request logs are not delivered "to a CloudTrail trail." CloudTrail records AWS API activity, not per-request WAF inspection logs. Option B describes querying S3 data directly with OpenSearch using "partition projection," which is an Athena/Glue concept; OpenSearch is typically used by ingesting data into an index (often via Firehose), not by directly querying S3 objects as a table in that manner.
Therefore, enabling WAF logs to S3 and analyzing them with Athena using partition projection is the correct solution.
