Understanding VPC Concepts

What does VPC stand for?

• Virtual Private Cloud

• Virtual Protected Cloud

• Virtual Private Connection

• Virtual Public Connection

What is the primary purpose of a VPC?

• To provide a logically isolated network in the cloud.

• To enhance security for on-premises servers.

• To provide a public network for all users.

• To increase the speed of internet connections.

How does VPC peering work?

• VPC peering is used for connecting on-premises networks to VPCs.

• VPC peering enables direct communication between two VPCs.

• VPC peering allows communication only within a single VPC.

• VPC peering requires a VPN connection to function.

What are the benefits of VPC peering?

• Less maintenance

• Slower data transfer speeds

• Cost savings on data transfer

• Improved security,

• Simplified network architecture

Can VPCs in different regions be peered?

• Yes, VPCs in different regions can be peered.

• VPC peering is only available within the same cloud provider.

• No, VPCs in different regions cannot be peered.

• VPCs can be peered across multiple accounts in different regions.

What is a security group in a VPC?

• A security group is a type of virtual machine in a VPC.

• A security group is a storage solution for AWS resources.

• A security group is a virtual firewall for controlling traffic to AWS resources in a VPC.

• A security group is a network monitoring tool for VPC traffic.

How do security groups control traffic?

• Security groups manage traffic by encrypting data packets.

• Security groups only allow traffic without any restrictions.

• Security groups control traffic by allowing or denying access based on defined rules.

• Security groups control traffic by monitoring user behavior.

What is the difference between a security group and a network ACL?

• A security group can only allow traffic, while a network ACL can only deny traffic.

• A security group is stateless and operates at the subnet level, while a network ACL is stateful and operates at the instance level.

• A security group is stateful and operates at the instance level, while a network ACL is stateless and operates at the subnet level.

• A security group applies to all instances in a region, while a network ACL applies to individual instances.

What are subnets in a VPC?

• Subnets are segments of a VPC's IP address range used to organize and isolate resources.

• Subnets are used to connect different VPCs together.

• Subnets are the physical servers that host a VPC.

• Subnets are the main components of a VPC's security group.

What is the purpose of public and private subnets?

• Public subnets are used for data storage; private subnets are for application hosting.

• Public subnets are only for internal network communication; private subnets allow public access.

• Public subnets allow internet access; private subnets enhance security by restricting access.

• Public subnets enhance security; private subnets provide internet access.
