Question 1

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?

Options :

A : Update the S3 bucket policy to ensure that clients that use pre-signed URLs have the S3:Get* permission and the S3:List* permission to access S3 objects in the bucket.

B : Add a StringEquals condition to the IAM role policy for the EC2 instance profile. Configure the policy condition to restrict access based on the s3:ResourceTag/ClientId tag of each invoice. Tag each generated invoice with the ID of its corresponding client.

C : Update the script to use AWS Security Token Service (AWS STS) to obtain new credentials each time the script runs by assuming a new role that has S3:GetObject permissions. Use the credentials to generate the pre-signed URLs.

D : Generate an access key and a secret key for an IAM user that has S3:GetObject permissions on the S3 bucket. Embed the keys into the script. Use the keys to generate the pre-signed URLs.

Answer: B

Question 2

A company is running a new workload across accounts in an organization in AWS Organizations. All running resources must have a tag of CostCenter, and the tag must have one of three approved values. The company must enforce this policy and must prevent any changes of the CostCenter tag to a non-approved value. Which solution will meet these requirements?

Options :

A : Use AWS Config custom policy rule and an SCP to deny non-approved aws:RequestTag/CostCenter values.

B : Use CloudTrail + EventBridge + Lambda to block creation.

C : Enable tag policies, define allowed values, enforce noncompliant operations, and use an SCP to deny creation when aws:RequestTag/CostCenter is null.

D : Enable tag policies and use EventBridge + Lambda to block changes.

Answer: C

Question 3

A company needs to scan all AWS Lambda functions for code vulnerabilities.

Options :

A : Use Amazon Macie.

B : Enable Amazon Inspector Lambda scanning.

C : Use GuardDuty and Security Hub.

D : Use GuardDuty Lambda Protection.

Answer: B

Question 4

An AWS Lambda function was misused to alter data, and a security engineer must identify who invoked the function and what output was produced. The engineer cannot find any logs created by the Lambda function in Amazon CloudWatch Logs. Which of the following explains why the logs are not available?

Options :

A : The execution role for the Lambda function did not grant permissions to write log data to CloudWatch Logs.

B : The Lambda function was invoked by using Amazon API Gateway, so the logs are not stored in CloudWatch Logs.

C : The execution role for the Lambda function did not grant permissions to write to the Amazon S3 bucket where CloudWatch Logs stores the logs.

D : The version of the Lambda function that was invoked was not current.

Answer: A

Question 5

A company needs a cloud-based, managed desktop solution for its workforce of remote employees. The company wants to ensure that the employees can access the desktops only by using company-provided devices. A security engineer must design a solution that will minimize cost and management overhead. Which solution will meet these requirements?

Options :

A : Deploy a custom virtual desktop infrastructure (VDI) solution with a restriction policy to allow access only from corporate devices.

B : Deploy a fleet of Amazon EC2 instances. Assign an instance to each employee with certificate-based device authentication that uses Windows Active Directory.

C : Deploy Amazon WorkSpaces. Set up a trusted device policy with IP blocking on the authentication gateway by using AWS Identity and Access Management (IAM).

D : Deploy Amazon WorkSpaces. Create client certificates, and deploy them to trusted devices. Enable restricted access at the directory level.
