CCP - Management and Governance Example Questions

Test your knowledge of Amazon Simple Storage Service (S3)

Question 1

Which AWS service is used by AWS Control Tower to manage and govern multiple AWS accounts?

Correct Answer: AWS Organizations

AWS Control Tower uses AWS Organizations to manage and govern multiple AWS accounts. AWS Organizations allows you to centrally manage and govern your environment as you grow and scale your AWS resources. It provides account management, consolidated billing, and hierarchical grouping of your accounts to meet your budgetary, security, and compliance needs. AWS Systems Manager is incorrect because it is used for operational tasks like collecting inventory, applying operating system patches, automating the creation of Amazon Machine Images (AMIs), and configuring operating systems. AWS Identity and Access Management (IAM) is incorrect because it is used for securely controlling access to AWS services and resources, not for managing multiple accounts. AWS CloudFormation and AWS Service Catalog are incorrect because they are used for infrastructure provisioning and governance of IT services, but not for centralized management of multiple AWS accounts.

Question 2

What is one of the main purposes of AWS Control Tower?

Correct Answer: To provide a centralized and automated way to set up and govern a secure, multi-account AWS environment

The main purpose of AWS Control Tower is to provide a centralized and automated way to set up and govern a secure, multi-account AWS environment. It helps organizations enforce compliance, security, and best practices across their AWS accounts. The other options, while related to AWS services, do not accurately describe the primary function of AWS Control Tower. Automating application deployment and management is more closely associated with services like AWS CloudFormation and AWS CodeDeploy. Monitoring and analyzing resource usage and costs is typically done using tools such as AWS Cost Explorer and AWS Budgets. Creating and managing containerized applications using Kubernetes is the domain of Amazon Elastic Kubernetes Service (EKS).

Question 3

Which AWS service is used in conjunction with AWS Control Tower to create a multi-account environment with pre-configured security and compliance policies?

Correct Answer: AWS Organizations

AWS Organizations is the correct answer. AWS Control Tower uses AWS Organizations to create and manage multiple AWS accounts in a secure and compliant manner. AWS Organizations enables you to centrally manage policies across multiple AWS accounts. It provides a way to group accounts into organizational units (OUs) and apply service control policies (SCPs) to enforce security and compliance policies across the accounts. AWS IAM is used for identity and access management within individual AWS accounts, but it does not directly provide the multi-account management capabilities that AWS Organizations offers. Amazon CloudWatch and AWS Config are used for monitoring, logging, and resource configuration management, but they are not the primary services used in conjunction with AWS Control Tower for creating a multi-account environment with pre-configured policies.
