AWS Tutorial AWS Solutions Architect and SysOps Administrator - EC2 Instance Types

This lecture covers various EC2 instance types and how AWS maintains physical infrastructure in availability zones. It explains creating an EC2 instance using the AWS management console, focusing on T2 micro and T2 large types. The lecture discusses vertical scaling, changing instance types, and the practical steps involved. It also highlights the importance of choosing the right instance type based on business needs and network performance.

What is allocated to a T2.micro EC2 instance upon creation?

• 2 GB of RAM and 2 virtual processors

• 1 GB of RAM and 1 virtual processor

• 4 GB of RAM and 4 virtual processors

• 8 GB of RAM and 8 virtual processors

What is vertical scaling in the context of AWS EC2?

• Increasing the number of instances

• Changing the instance type to a larger or smaller one

• Adding more storage to an instance

• Distributing traffic across multiple instances

What happens to the current EC2 instance when you change its type?

• It is upgraded without any downtime

• It is destroyed and a new instance is created

• It is paused and resumed with new settings

• It is duplicated with the new type

During the instance type change process, what happens to client access?

• Clients can access the instance without interruption

• Clients experience temporary downtime

• Clients are redirected to a backup instance

• Clients receive a notification to retry later

After changing the instance type to T2.large, what is the new RAM allocation?

• 4 GB

• 1 GB

• 8 GB

• 2 GB

What should be considered when choosing an EC2 instance type based on network performance?

• The type of storage used

• The required network bandwidth

• The amount of allocated memory

• The number of virtual processors

Which of the following is a factor in determining the right EC2 instance type?

• The number of AWS accounts

• The network performance requirements

• The geographical location of the user

• The color of the instance
