The user notified the security team about the incident after removing the exposed credentials from the forum.Which initial steps should a security engineer take to mitigate the exposure without interrupting operations? (Select TWO.)

A : Reset the password for the root user on the account.

B : Terminate or disable any resources the user has access to.

C : Implement a deny policy blocking access to resources.

D : Invalidate any temporary security credentials.

E : Delete the access key ID and secret access key.

Answer: C,E

Question 2

A company wants to start processing sensitive data on Amazon EC2 instances. The company will use Amazon CloudWatch Logs to monitor, store, and access log files from the EC2 instances. The company's developers use CloudWatch Logs for troubleshooting. A security engineer must implement a solution that prevents the developers from viewing the sensitive data The solution must automatically apply to any new log groups that are created in the account in the future. Which solution will meet these requirements?

A : Create a CloudWatch Logs account-wide data protection policy. Specify the appropriate data identifiers for the policy. Ensure that the developers do not have the logs:Unmask 1AM permission.

B : Export the CloudWatch Logs data to an Amazon S3 bucket. Set up automated discovery by using Amazon Macie on the S3 bucket. Create a custom data identifier for the sensitive data. Remove the developers' access to CloudWatch Logs. Grant permissions for the developers to view the exported log data in Amazon S3.

C : Export the CloudWatch Logs data to an Amazon S3 bucket. Set up automated discovery by using Amazon Macie on the S3 bucket. Specify the appropriate managed data identifiers. Remove the developers' access to CloudWatch Logs. Grant permissions for the developers to view the exported log data in Amazon S3.

D : Create a CloudWatch Logs data protection policy for each log group. Specify the appropriate data identifiers for the policy. Ensure that the developers do not have the logsiUnmask 1AM permission

Answer: A

Question 3

A fintech company offers a web application that stores files on Amazon S3 and processes transactions on Amazon EC2. Users are complaining about slow response times, and recent cybersecurity audits have raised concerns about web content security.The company needs to accelerate content delivery while enhancing security and privacy, without altering the application code.What combination of actions should the company undertake to meet these requirements? (Select TWO.)

A : Use an AWS WAF web ACL with predefined AWS managed rules to add HTTP security headers to origin responses.

B : Configure Amazon CloudFront and set up a distribution for the S3 and EC2 origins to accelerate content delivery

C : Deploy Amazon ElastiCache to cache the responses of the application endpoints

D : Use an AWS Lambda function configured with CloudFront (Lambda@Edge) to add HTTP security headers on origin responses

E : Utilize an Application Load Balancer (ALB) with enabled Sticky Sessions to preserve the connection header from incoming client requests after forwarding the response back to the client.

Answer: B,D

Question 4

A financial firm receives a warning from the AWS Trust and Safety team about a potential security threat. An IAM access key linked to an IT administrator seems to have been compromised. This key is employed in an automated process that uses AWS Lambda functions to launch AWS Elastic Beanstalk environments.The firm's security engineer is tasked with addressing this security issue, preventing further use of the exposed access key, and bolstering security practices.Which of the following steps would be the most appropriate in this scenario?

A : Track down the exposed IAM access key and deactivate or remove it. Establish new access keys for the Lambda automation process and integrate them into the system. In the AWS account associated with the exposed key, create a new support case in AWS Support detailing the remediation measures.

B : Find the exposed IAM access key and remove the associated IAM user. Generate a new access key, store it in AWS Systems Manager Parameter Store, and encrypt it using an AWS KMS customer-managed key. Modify the AWS Lambda functions to fetch the access key from Parameter Store during execution. Log a new support case with AWS Support providing the details of the remediation steps.

C : Deactivate or delete the compromised IAM access key. Generate a new access key and save it as an environment variable within the configuration settings of the automation system-s Lambda functions. Respond to the AWS Trust and Safety team detailing the remediation actions taken.

D : Disable or delete the compromised IAM access key. Stop using static IAM access keys and instead, create a new IAM role for the Lambda automation process. Assign this role to the AWS Lambda functions. Respond to the AWS Trust and Safety team detailing the remediation actions.

Answer: D

Question 5

A new application requires an AWS KMS key for encrypting sensitive data. The security policy requires that separate keys are used for different AWS services.How can the AWS KMS key be constrained to work with only Amazon S3?

A : Configure the key policy with a kms:CallerAccount condition key that limits use of the KMS key to identities in the specific AWS account.

B : Configure the key policy with a kms:RequestAlias condition key that limits use of the KMS key to requests that use a specific alias.

C : Configure the key policy with a kms:ViaService condition key that limits use of the KMS key to the Amazon S3 service name.

D : Configure the key policy with a kms:ViaService condition key that limits use of the KMS key to the Amazon S3 service name.

Answer: C
