CLF-C02 Exam Questions Tutorials

AVPC (Virtual Private Cloud)in AWS is a logically isolated network that you define in the AWS Cloud. Within a VPC, you can create subnets, route tables, network gateways, and more.

D. Internet Gateway: An internet gateway is a component that allows communication between resources in a VPC and the internet.

E. Subnet: A subnet is a range of IP addresses in your VPC. Subnets can be public or private and are essential for organizing resources within a VPC.

Why other options are not suitable:

A. Amazon API Gateway: Used for creating and managing APIs, not a direct component of a VPC.

B. Amazon S3 buckets and objects: Amazon S3 is a storage service; its resources are globally accessible and not confined to a VPC.

C. AWS Storage Gateway: A hybrid cloud storage service, not a core component of a VPC.

Under the AWS shared responsibility model, AWS is responsible for the security "of" the cloud, which includes the physical infrastructure, networking, and hypervisor layer. The customer, however, is responsible for security "in" the cloud, which includes managing the security of their data, patching and maintaining their guest operating system and applications, and managing identity and access. The responsibilities of shredding disk drives, preventing packet capture at the hypervisor level, and physical monitoring are handled by AWS as part of its responsibility for security "of" the cloud.

AnIAM useris created when the company needs to provide unique credentials (username and password) to individuals who need access to the AWS Management Console or programmatic access (using access keys) to AWS services.

B. When the company creates AWS access credentials for individuals: Correct, as an IAM user is created to provide credentials for specific individuals.

D. When the company needs to add users to IAM groups: Correct, as IAM users can be added to groups to apply permissions and policies at a group level.

A. When an application that runs on Amazon EC2 instances requires access to other AWS services: Incorrect, as an IAM role is more appropriate for applications running on EC2 to assume temporary credentials.

C. When the company creates an application that runs on a mobile phone that makes requests to AWS: Incorrect, as using Cognito or a role with temporary credentials is more suitable.

E. When users are authenticated in the corporate network and want to be able to use AWS without having to sign in a second time: Incorrect, as this use case typically involves IAM roles combined with AWS Single Sign-On (SSO).

AWS Lambdais a serverless compute service that allows users to run code in response to events without provisioning or managing servers. It automatically scales the application by running code only when needed, and users are charged only for the compute time consumed. This service is ideal for applications that require event-driven compute functions.

B. AWS CloudFormation: Incorrect, as it is an infrastructure-as-code service that helps users automate the deployment of AWS resources, not a serverless compute service.

C. AWS Elastic Beanstalk: Incorrect, as it is a Platform-as-a-Service (PaaS) that still involves managing servers, even though it abstracts much of the infrastructure management.

D. Elastic Load Balancing: Incorrect, as it is a service for distributing incoming application or network traffic across multiple targets, not a serverless compute service.
