CLF-C02 Exam Dumps - Amazon Web Services AWS Certified Foundational Questions and Answers

AWS Shield is a managed Distributed Denial of Service (DDoS) protection service that safeguards AWS applications against network and transport layer attacks. AWS Shield Standard is automatically included with all AWS services and offers protection against common DDoS attacks. For more advanced protection, AWS Shield Advanced provides additional DDoS mitigation measures. Although AWS WAF, Firewall Manager, and GuardDuty contribute to security, they do not specialize in DDoS mitigation at the network layer like AWS Shield does.

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.

Rightsizing involves adjusting instance types based on actual utilization to optimize costs and performance. Changing the size and type of EC2 instances according to utilization data achieves this with minimal operational overhead. Adding instances or changing payment methods does not directly address instance resizing, and reprovisioning with larger instances may not be optimal based on actual usage.

AWS CloudHSM provides hardware-based key management to manage and protect encryption keys in the AWS Cloud. It allows customers to generate and use their own encryption keys while complying withrigorous security requirements. WhileAWS Certificate Manager (ACM)manages SSL/TLS certificates, it does not handle encryption keys independently, andAWS License ManagerandAWS Directory Serviceare not designed for managing encryption keys. AWS KMS is also relevant for key management but wasn't listed as an option in this question.

The AWS Architecture Center provides examples, best practices, and architectural blueprints for various AWS Cloud solutions. It includes whitepapers, reference architectures, and detailed diagrams to help users design secure, scalable, and reliable applications on AWS. Other services like AWS Marketplace, Service Catalog, and Trusted Advisor do not offer solution design examples.

AWS IAM Identity Center (formerly AWS Single Sign-On) provides centralized management of user access to multiple AWS accounts within an organization in AWS Organizations. It allows users to log in once and gain access to all assigned accounts without managing separate logins for each account. Amazon Cognito is generally used for application-level user management and authentication, not for managing access across AWS accounts.

AWS IAM Identity Center provides centralized access management across multiple AWS accounts, enabling organizations to manage employee access efficiently. It is specifically designed for this purpose within AWS Organizations. AWS STS provides temporary credentials but does not manage multiple account access centrally, while IAM Access Analyzer and Secrets Manager serve different purposes related to access and secret management.

AWS provides the flexibility to scale resources up or down on demand, enabling companies to test new applications without making long-term commitments. This principle allows for cost efficiency and agility during testing and development. The other options do not specifically highlight the benefits of flexible, on-demand resource scaling.

AWS CloudFormation allows developers to create, manage, and deploy AWS resources using templates, ensuring a standardized and repeatable infrastructure setup. It’s ideal for setting up development, test, and production environments consistently. AWS Cloud Map, CloudFront, and CloudTrail do not provide templated infrastructure management capabilities.
