The Accounting department at Example Corp. has made a decision to hire a third-party firm, AnyCompany, to monitor Example Corp.'s AWS account to help optimize costs.
The Security Engineer for Example Corp. has been tasked with providing AnyCompany with access to the required Example Corp. AWS resources. The Engineer has created an IAM role and granted permission to AnyCompany's AWS account to assume this role.
When customers contact AnyCompany, they provide their role ARN for validation. The Engineer is concerned that one of AnyCompany's other customers might deduce Example Corp.
's role ARN and potentially compromise the company's account.
What steps should the Engineer perform to prevent this outcome?
A. Create an IAM user and generate a set of long-term credentials. Provide the credentials to AnyCompany. Monitor access in IAM access advisor and plan to rotate credentials on a recurring basis.
B. Request an external ID from AnyCompany and add a condition with sts:Externald to the role's trust policy.
C. Require two-factor authentication by adding a condition to the role's trust policy with aws:MultiFactorAuthPresent.
D. Request an IP range from AnyCompany and add a condition with aws:SourceIp to the role's trust policy.
A company maintains sensitive data in an Amazon S3 bucket that must be protected using an AWS KMS CMK. The company requires that keys be rotated automatically every year.
How should the bucket be configured?
A. Select server-side encryption with Amazon S3-managed keys (SSE-S3) and select an AWS-managed CMK.
B. Select Amazon S3-AWS KMS managed encryption keys (S3-KMS) and select a customer-managed CMK with key rotation enabled.
C. Select server-side encryption with Amazon S3-managed keys (SSE-S3) and select a customer-managed CMK that has imported key material.
D. Select server-side encryption with AWS KMS-managed keys (SSE-KMS) and select an alias to an AWS-managed CMK.
An Amazon S3 bucket is encrypted using an AWS KMS CMK. An IAM user is unable to download objects from the S3 bucket using the AWS ManagementConsole; however, other users can download objects from the S3 bucket.
Which policies should the Security Engineer review and modify to resolve this issue? (Choose three.)
A. The CMK policy
B. The VPC endpoint policy
C. The S3 bucket policy
D. The S3 ACL
E. The IAM policy
While analyzing a company's security solution, a Security Engineer wants to secure the AWS account root user.
What should the Security Engineer do to provide the highest level of security for the account?
A. Create a new IAM user that has administrator permissions in the AWS account. Delete the password for the AWS account root user.
B. Create a new IAM user that has administrator permissions in the AWS account. Modify the permissions for the existing IAM users.
C. Replace the access key for the AWS account root user. Delete the password for the AWS account root user.
D. Create a new IAM user that has administrator permissions in the AWS account. Enable multi-factor authentication for the AWS account root user.
A Security Engineer is working with a Product team building a web application on AWS. The application uses Amazon S3 to host the static content, Amazon APIGateway to provide RESTful services; and Amazon DynamoDB as the backend data store. The users already exist in a directory that is exposed through a SAML identity provider.
Which combination of the following actions should the Engineer take to enable users to be authenticated into the web application and call APIs? (Choose three.)
A. Create a custom authorization service using AWS Lambda.
B. Configure a SAML identity provider in Amazon Cognito to map attributes to the Amazon Cognito user pool attributes.
C. Configure the SAML identity provider to add the Amazon Cognito user pool as a relying party.
D. Configure an Amazon Cognito identity pool to integrate with social login providers.
E. Update DynamoDB to store the user email addresses and passwords.
F. Update API Gateway to use a COGNITO_USER_POOLS authorizer.
While securing the connection between a company's VPC and its on-premises data center, a Security Engineer sent a ping command from an on-premises host(IP address 203.0.113.12) to an Amazon EC2 instance (IP address 172.31.16.139). The ping command did not return a response. The flow log in the VPC showed the following:
2 123456789010 eni-1235b8ca 203.0.113.12 172.31.16.139 0 0 1 4 336 1432917027 1432917142 ACCEPT OK
2 123456789010 eni-1235b8ca 172.31.16.139 203.0.113.12 0 0 1 4 336 1432917094 1432917142 REJECT OK
What action should be performed to allow the ping to work?
A. In the security group of the EC2 instance, allow inbound ICMP traffic.
B. In the security group of the EC2 instance, allow outbound ICMP traffic.
C. In the VPC's NACL, allow inbound ICMP traffic.
D. In the VPC's NACL, allow outbound ICMP traffic.
A Security Engineer is building a Java application that is running on Amazon EC2. The application communicates with an Amazon RDS instance and authenticates with a user name and password.
Which combination of steps can the Engineer take to protect the credentials and minimize downtime when the credentials are rotated? (Choose two.)
A. Have a Database Administrator encrypt the credentials and store the ciphertext in Amazon S3. Grant permission to the instance role associated with the EC2 instance to read the object and decrypt the ciphertext.
B. Configure a scheduled job that updates the credential in AWS Systems Manager Parameter Store and notifies the Engineer that the application needs to be restarted.
C. Configure automatic rotation of credentials in AWS Secrets Manager.
D. Store the credential in an encrypted string parameter in AWS Systems Manager Parameter Store. Grant permission to the instance role associated with the EC2 instance to access the parameter and the AWS KMS key that is used to encrypt it.
E. Configure the Java application to catch a connection failure and make a call to AWS Secrets Manager to retrieve updated credentials when the password is rotated. Grant permission to the instance role associated with the EC2 instance to access Secrets Manager.
A company has several production AWS accounts and a central security AWS account. The security account is used for centralized monitoring and has IAM privileges to all resources in every corporate account. All of the company's Amazon S3 buckets are tagged with a value denoting the data classification of their contents.
A Security Engineer is deploying a monitoring solution in the security account that will enforce bucket policy compliance. The system must monitor S3 buckets in all production accounts and confirm that any policy change is in accordance with the bucket's data classification. If any change is out of compliance, the Security team must be notified quickly.
Which combination of actions would build the required solution? (Choose three.)
A. Configure Amazon CloudWatch Events in the production accounts to send all S3 events to the security account event bus.
B. Enable Amazon GuardDuty in the security account, and join the production accounts as members.
C. Configure an Amazon CloudWatch Events rule in the security account to detect S3 bucket creation or modification events.
D. Enable AWS Trusted Advisor and activate email notifications for an email address assigned to the security contact.
E. Invoke an AWS Lambda function in the security account to analyze S3 bucket settings in response to S3 events, and send non-compliance notifications to the Security team.
F. Configure event notifications on S3 buckets for PUT, POST, and DELETE events.
A company plans to migrate a sensitive dataset to Amazon S3. A Security Engineer must ensure that the data is encrypted at rest. The encryption solution must enable the company to generate its own keys without needing to manage key storage or the encryption process.

B. Server-side encryption with AWS KMS-managed keys (SSE-KMS)
C. Server-side encryption with customer-provided keys (SSE-C)
D. Client-side encryption with an AWS KMS-managed CMK
