AWS Organizations Overview:

AWS Organizations allows a company to manage multiple AWS accounts under a single organization.

Through the feature of consolidated billing, a company can receive a single bill for all linked accounts.

Key Features of Consolidated Billing in AWS Organizations:

Aggregates usage across accounts to take advantage of volume pricing discounts.

Provides detailed cost reports for individual linked accounts.

Simplifies payment processing by centralizing billing.

Why Other Options Are Incorrect:

A. AWS Billing and Cost Management console:Used for managing budgets and payments but does not set up consolidated billing.

C. AWS Cost and Usage Report:Provides detailed cost and usage reports but does not set up consolidated billing.

D. AWS Systems Manager:Focuses on operational management, not billing.

Enforcing multi-factor authentication (MFA) for privileged users enhances account security by requiring a second form of authentication. It reduces the risk of unauthorized access, even if credentials are compromised. Removing the root account is not possible, and creating access keys for the root account or privileged users can increase security risks rather than reduce them.

AWS Certificate Manager (ACM) Overview:

ACM simplifies the process of provisioning, managing, and deploying SSL/TLS certificates.

These certificates are used to secure HTTPS connections, ensuring encrypted communication between clients and servers.

How ACM Meets the Goal:

Provides free public SSL/TLS certificates.

Automates certificate renewals and deployment with services like Elastic Load Balancing and Amazon CloudFront.

Reduces the operational overhead of managing SSL/TLS certificates.

Why Other Options Are Incorrect:

A. AWS WAF:Focuses on application-layer protection (e.g., SQL injection, cross-site scripting) but does not handle SSL/TLS encryption.

B. AWS Shield:Provides protection against DDoS attacks, not encryption.

C. Amazon VPC:Used for networking and security at the infrastructure level but does not manage SSL/TLS certificates.
