AWS Certified Security - Specialty Questions and Answers

Question 69

A company has an AWS account that hosts a production application. The company receives an email notification that Amazon GuardDuty has detected an Impact:lAMUser/AnomalousBehavior finding in the account. A security engineer needs to run the investigation playbook for this security incident and must collect and analyze the information without affecting the application.

Which solution will meet these requirements MOST quickly?

Options:

A.

Log in to the AWS account by using read-only credentials. Review the GuardDuty finding for details about the IAM credentials that were used. Use the IAM console to add a DenyAll policy to the IAM principal.

B.

Log in to the AWS account by using read-only credentials. Review the GuardDuty finding to determine which API calls initiated the finding. Use Amazon Detective to review the API calls in context.

C.

Log in to the AWS account by using administrator credentials. Review the GuardDuty finding for details about the IAM credentials that were used. Use the IAM console to add a DenyAll policy to the IAM principal.

D.

Log in to the AWS account by using read-only credentials. Review the GuardDuty finding to determine which API calls initiated the finding. Use AWS CloudTrail Insights and AWS CloudTrail Lake to review the API calls in context.

Question 70

A company has several workloads running on AWS. Employees are required to authenticate using on-premises ADFS and SSO to access the AWS Management

Console. Developers migrated an existing legacy web application to an Amazon EC2 instance. Employees need to access this application from anywhere on the internet, but currently, there is no authentication system built into the application.

How should the Security Engineer implement employee-only access to this system without changing the application?

Options:

A.

Place the application behind an Application Load Balancer (ALB). Use Amazon Cognito as authentication for the ALB. Define a SAML-based Amazon Cognito user pool and connect it to ADFS.

B.

Implement AWS SSO in the master account and link it to ADFS as an identity provider. Define the EC2 instance as a managed resource, then apply an IAM policy on the resource.

C.

Define an Amazon Cognito identity pool, then install the connector on the Active Directory server. Use the Amazon Cognito SDK on the application instance to authenticate the employees using their Active Directory user names and passwords.

D.

Create an AWS Lambda custom authorizer as the authenticator for a reverse proxy on Amazon EC2. Ensure the security group on Amazon EC2 only allows access from the Lambda function.

Question 71

A company finds that one of its Amazon EC2 instances suddenly has a high CPU usage. The company does not know whether the EC2 instance is compromised or whether the operating system is performing background cleanup.

Which combination of steps should a security engineer take before investigating the issue? (Select THREE.)

Options:

A.

Disable termination protection for the EC2 instance if termination protection has not been disabled.

B.

Enable termination protection for the EC2 instance if termination protection has not been enabled.

C.

Take snapshots of the Amazon Elastic Block Store (Amazon EBS) data volumes that are attached to the EC2 instance.

D.

Remove all snapshots of the Amazon Elastic Block Store (Amazon EBS) data volumes that are attached to the EC2 instance.

E.

Capture the EC2 instance metadata, and then tag the EC2 instance as under quarantine.

F.

Immediately remove any entries in the EC2 instance metadata that contain sensitive information.

Question 72

A company uses AWS Organizations. The company wants to implement short-term cre-dentials for third-party AWS accounts to use to access accounts within the com-pany's organization. Access is for the AWS Management Console and third-party software-as-a-service (SaaS) applications. Trust must be enhanced to prevent two external accounts from using the same credentials. The solution must require the least possible operational effort.

Which solution will meet these requirements?

Options:

A.

Use a bearer token authentication with OAuth or SAML to manage and share a central Amazon Cognito user pool across multiple Amazon API Gateway APIs.

B.

Implement AWS IAM Identity Center (AWS Single Sign-On), and use an identi-ty source of choice. Grant access to users and groups from other accounts by using permission sets that are assigned by account.

C.

Create a unique IAM role for each external account. Create a trust policy. Use AWS Secrets Manager to create a random external key.

D.

Create a unique IAM role for each external account. Create a trust policy that includes a condition that uses the sts:Externalld condition key.
