Questions # 21:

A company uses a third-party identity provider and SAML-based SSO for its AWS accounts. After the third-party identity provider renewed an expired signing certificate, users saw the following message when trying to log in:

Error: Response Signature Invalid (Service: AWSSecurityTokenService; Status Code: 400; Error Code: InvalidldentityToken)

A security engineer needs to provide a solution that corrects the error and min-imizes operational overhead.

Which solution meets these requirements?

Options:

A.

Upload the third-party signing certificate's new private key to the AWS identity provider entity defined in AWS Identity and Access Management (IAM) by using the AWS Management Console.

B.

Sign the identity provider's metadata file with the new public key. Upload the signature to the AWS identity provider entity defined in AWS Identity and Access Management (IAM) by using the AWS CU.

C.

Download the updated SAML metadata file from the identity service provid-er. Update the file in the AWS identity provider entity defined in AWS Identity and Access Management (IAM) by using the AWS CLI.

D.

Configure the AWS identity provider entity defined in AWS Identity and Ac-cess Management (IAM) to synchronously fetch the new public key by using the AWS Management Console.

Questions # 22:

A company has an encrypted Amazon Aurora DB cluster in the us-east-1 Region. The DB cluster is encrypted with an AWS Key Management Service (AWS KMS) customer managed key. To meet compliance requirements, the company needs to copy a DB snapshot to the us-west-1 Region. However, when the company tries to copy the snapshot to us-west-1 the company cannot access the key that was used to encrypt the original database.

What should the company do to set up the snapshot in us-west-1 with proper encryption?

Options:

A.

Use AWS Secrets Manager to store the customer managed key in us-west-1 as a secret Use this secret to encrypt the snapshot in us-west-1.

B.

Create a new customer managed key in us-west-1. Use this new key to encrypt the snapshot in us-west-1.

C.

Create an IAM policy that allows access to the customer managed key in us-east-1. Specify am aws kms us-west-1 " as the principal.

D.

Create an IAM policy that allows access to the customer managed key in us-east-1. Specify arn aws rds us-west-1. * as the principal.

Questions # 23:

A company developed an application by using AWS Lambda, Amazon S3, Amazon Simple Notification Service (Amazon SNS), and Amazon DynamoDB. An external application puts objects into the company's S3 bucket and tags the objects with date and time. A Lambda function periodically pulls data from the company's S3 bucket based on date and time tags and inserts specific values into a DynamoDB table for further processing.

The data includes personally identifiable information (Pll). The company must remove data that is older than 30 days from the S3 bucket and the DynamoDB table.

Which solution will meet this requirement with the MOST operational efficiency?

Options:

A.

Update the Lambda function to add a TTL S3 flag to S3 objects. Create an S3 Lifecycle policy to expire objects that are older than 30 days by using the TTL S3 flag.

B.

Create an S3 Lifecycle policy to expire objects that are older than 30 days. Update the Lambda function to add the TTL attribute in the DynamoDB table. Enable TTL on the DynamoDB table to expire entires that are older than 30 days based on the TTL attribute.

C.

Create an S3 Lifecycle policy to expire objects that are older than 30 days and to add all prefixes to the S3 bucket. Update the Lambda function to delete entries that are older than 30 days.

D.

Create an S3 Lifecycle policy to expire objects that are older than 30 days by using object tags. Update the Lambda function to delete entries that are older than 30 days.

Questions # 24:

A company has developed a new Amazon RDS database application. The company must secure the ROS database credentials for encryption in transit and encryption at rest. The company also must rotate the credentials automatically on a regular basis.

Which solution meets these requirements?

Options:

A.

Use IAM Systems Manager Parameter Store to store the database credentiais. Configureautomatic rotation of the credentials.

B.

Use IAM Secrets Manager to store the database credentials. Configure automat* rotation of the credentials

C.

Store the database credentials in an Amazon S3 bucket that is configured with server-side encryption with S3 managed encryption keys (SSE-S3) Rotate the credentials with IAM database authentication.

D.

Store the database credentials m Amazon S3 Glacier, and use S3 Glacier Vault Lock Configure an IAM Lambda function to rotate the credentials on a scheduled basts

Questions # 25:

A security engineer wants to evaluate configuration changes to a specific AWS resource to ensure that the resource meets compliance standards. However, the security engineer is concerned about a situation in which several configuration changes are made to the resource in quick succession. The security engineer wants to record only the latest configuration of that resource to indicate the cumulative impact of the set of changes.

Which solution will meet this requirement in the MOST operationally efficient way?

Options:

A.

Use AWS CloudTrail to detect the configuration changes by filtering API calls to monitor the changes. Use the most recent API call to indicate the cumulative impact of multiple calls

B.

Use AWS Config to detect the configuration changes and to record the latest configuration in case of multiple configuration changes.

C.

Use Amazon CloudWatch to detect the configuration changes by filtering API calls to monitor the changes. Use the most recent API call to indicate the cumulative impact of multiple calls.

D.

Use AWS Cloud Map to detect the configuration changes. Generate a report of configuration changes from AWS Cloud Map to track the latest state by using a sliding time window.

Questions # 26:

A company is building a secure solution that relies on an AWS Key Management Service (AWS KMS) customer managed key. The company wants to allow AWS Lambda to use the KMS key However, the company wants to prevent Amazon EC2 from using the key.

Which solution will meet these requirements?

Options:

A.

Create an 1AM policy that explicitly denies permission to the key Attach the policy to all EC2 instance profiles Create an 1AM policy that explicitly allows permission to the key Attach the policy to all Lambda function roles.

B.

Create a custom key policy for the key. Use the kms: ViaService condition key to deny access to requests from Amazon EC2 and to allow access to requests from Lambda. Use the Lambda 1AM role as the principal.

C.

Create a custom key policy tor the key Use the aws Sourcelp condition key to deny access to requests from Amazon EC2 Use the aws: Authorized Service condition key to allow access to requests from Lambda Use the Lambda 1AM role as the principal.

D.

Create an SCP that explicitly denies permission to the key for Amazon EC2 and explicitly allows permission to the key for Lambda Attach the SCP to the AWS account.

Questions # 27:

A company is building a data processing application that uses AWS Lambda functions The application's Lambda functions need to communicate with an Amazon RDS OB instance that is deployed within a VPC in the same AWS account

Which solution meets these requirements in the MOST secure way?

Questions # 29:

A company is storing data in Amazon S3 Glacier. A security engineer implemented a new vault lock policy for 10 TB of data and called the initiate-vault-lock operation 12hours ago. The audit team identified a typo in the policy that is allowing unintended access to the vault.

B.

Copy the vault data to a new S3 bucket. Delete the vault. Create a new vault with the data.

D.

Update the policy. Call the initiate-vault-lock operation again to apply the new policy.

Questions # 30:

A security engineer is creating an AWS Lambda function. The Lambda function needs to use a role that is named LambdaAuditRole to assume a role that is named AcmeAuditFactoryRole in a different AWS account.

When the code is processed, the following error message appears: "An error oc-curred (AccessDenied) when calling the AssumeRole operation."

A.

Ensure that LambdaAuditRole has the sts:AssumeRole permission for Ac-meAuditFactoryRole.

B.
