AWS Solutions Architect Associate (SAA-C02) Exam Prep Course - 2021 UPDATED! - Virtual Private Cloud (VPC) Peering

The video tutorial explains VPC peering, a method to connect two virtual private clouds (VPCs) in AWS, similar to a WAN connection. It highlights the non-transitive nature of VPC peering, meaning direct connections are required between each pair of VPCs. The process of creating VPC peers involves initiating and accepting requests, ensuring unique CIDR blocks, and configuring routing and security group rules. The tutorial emphasizes the importance of understanding these concepts for effective cloud networking.

What is the primary purpose of VPC peering?

• To create a backup for VPCs

• To reduce the cost of VPC operations

• To allow direct communication between different VPCs

• To enhance the security of VPCs

How is VPC peering similar to a WAN connection?

• Both connect different networks for communication

• Both are used for security purposes

• Both require physical cables

• Both are used for data storage

What does it mean when VPC peering is described as non-transitive?

• A VPC can only communicate with directly peered VPCs

• A VPC can communicate with any other VPC

• A VPC can share resources with all VPCs

• A VPC can automatically connect to all VPCs in the network

In the context of VPC peering, what is required for two VPCs to communicate?

• A shared CIDR block

• A direct peering connection

• A common security group

• A single owner for both VPCs

Who can initiate a VPC peering request?

• An AWS administrator

• Only the owner of the VPC

• A network engineer

• Any user with access

Why is it important to have unique CIDR blocks for each VPC?

• To enhance security

• To increase network speed

• To prevent IP address conflicts

• To reduce costs

What must be configured to ensure successful communication between peered VPCs?

• A shared security group

• A single owner for both VPCs

• Defined routes and security group rules

• A common CIDR block
