AWS Certified Cloud Practitioner (CLF-C01)- AWS Elastic Compute Cloud (EC2) Part 2

The video tutorial covers the Amazon Machine Image (AMI), explaining its role in launching EC2 instances with pre-configured operating systems and applications. It discusses customizing and distributing AMIs within organizations, the types of virtualization available, and the importance of IP addressing, including Elastic IPs for static assignments. The tutorial also highlights the use of key pairs for secure access to instances, ensuring secure management of credentials.

What is the primary purpose of an Amazon Machine Image (AMI)?

• To manage AWS billing and costs

• To act as a backup for AWS databases

• To serve as a virtual image for launching EC2 instances

• To provide a physical server for AWS

Where can you find third-party AMIs for use in your AWS account?

• AWS Marketplace

• AWS Billing Console

• AWS Support Center

• AWS Cost Explorer

What is a key difference between HVM and PV virtualization types?

• HVM provides a fully virtualized hardware set, while PV does not

• HVM can run on older hardware, while PV cannot

• PV allows for enhanced networking, while HVM does not

• HVM requires a special bootloader, while PV does not

Why might you need a static IP address for an EC2 instance?

• To enable automatic scaling

• To improve instance performance

• To reduce AWS billing costs

• To ensure consistent access to a web server

What is the role of an Elastic IP address in AWS?

• To manage AWS user permissions

• To provide a dynamic IP address for EC2 instances

• To offer a static IP address that can be reassigned

• To encrypt data in transit

How does AWS ensure secure access to EC2 instances?

• By using a shared password for all instances

• By requiring a physical token

• By sending passwords via email

• By using a public-private key pair

What is the purpose of a key pair in AWS EC2?

• To encrypt and decrypt passwords for instance access

• To monitor EC2 instance performance

• To manage AWS billing

• To provide a backup for EC2 instances
