AWS Certified Solutions Architect Associate (SAA-C03) - VPC Peering

The video tutorial explains VPC peering, a method to connect two virtual private clouds (VPCs) in AWS. It compares VPC peering to WAN connections and highlights its non-transitive nature, meaning direct peering is required between each pair of VPCs for communication. The process of creating VPC peers involves initiating and accepting requests, ensuring unique CIDR blocks, and configuring routing and security group rules. Best practices include maintaining unique CIDR blocks for each VPC and tracking them using a spreadsheet.

What is the primary purpose of VPC Peering?

• To enable direct communication between different VPCs

• To create a backup of VPC data

• To enhance the security of a single VPC

• To reduce the cost of cloud services

How is VPC Peering similar to a WAN connection?

• Both are used to enhance security

• Both are used to reduce latency

• Both are used to store data

• Both are used to connect different networks

What does it mean that VPC Peering is not transitive?

• A VPC can communicate with all VPCs in the same region

• A VPC can only communicate with directly peered VPCs

• A VPC can communicate with VPCs in different regions

• A VPC can communicate with any other VPC

Who can initiate a VPC Peering connection?

• Any user with AWS access

• Only the VPC owner

• Any user with network permissions

• Any administrator

Why is it important to have unique CIDR blocks in VPC Peering?

• To ensure data is encrypted

• To prevent IP address conflicts

• To reduce latency

• To increase storage capacity

What is necessary for communication to occur over a VPC Peering connection?

• A shared security group

• A defined route in the routing table

• A direct internet connection

• A common CIDR block

What role do security group rules play in VPC Peering?

• They automatically configure routing tables

• They increase the speed of data transfer

• They determine the cost of peering

• They decide what traffic can pass through the peering link
