Amazon VPC Quiz

What is the primary purpose of a Virtual Private Cloud (VPC) in cloud computing?

• Resource scaling
• Network isolation
• Load balancing
• Data storage

When setting up a custom VPC in AWS, what is a CIDR block, and how is it used?

• It's a unique VPC identifier
• It defines the IP address range for the VPC
• It specifies the number of subnets

In AWS, what is the key difference between a Security Group and a Network Access Control List (NACL)?

• Security Groups control traffic at the subnet level, while NACLs operate at the instance level.
• Security Groups operate at the instance level, while NACLs control traffic at the subnet level.
• Security Groups are stateful, while NACLs are stateless.
• Security Groups are only applicable to outbound traffic, while NACLs control inbound traffic.

How does VPC peering differ from VPC Endpoint?
