One data center can connect hardware VPN with AWS VPC. AWS supports internet protocol security VPN connections only. The encrypted data will be transferred. VPN connection helps in data security while transiting. No internet gateway is required to establish a hardware VPN connection with AWS VPC.

Yes, we can use our existing AMIs in the AWS VPC in the same registered zone.

If you want to connect Amazon EC2-classic instances to VPC, you have to use ClassicLink. This work only within the same region and this makes use of private IP addresses. Its working is simple- you just have to enable ClassicLink in your VPC account and associate a security group from VPC to EC2-classic instance.
This type of questions are the additions AWS VPC interview questions that you shouldn’t miss so prepare yourself with the answer.

This AWS VPC provides the given below features:
IPv4 and IPv6 address book.
Internet connectivity.
Subnet creation.
Route tables.
Elastic IP addresses.
Network/ Subnet security.
Additional networking services.

The foremost element in Amazon VPC architecture is VPC network itself. It’s a logically separated part of AWS cloud. It’s possible to define your Virtual Private Cloud’s IP address from the range you’ve chosen. The second element is the Internet Gateway which is the connecting point between your VPC and the public internet. Subnets are the functional parts of your private cloud’s IP address range.
NAT Gateways are used to connect between instances of your private subnet with internet or other AWS services. Customer Gateways are your side of a VPN connection in AWS while Virtual Private Gateways are Amazon VPC side of VPN connection. This type of questions lies under the general or basic AWS VPC interview questions. Whether you are a fresher or have some experience, you may come across such questions so get prepared with the answer.
Element Brief description
Virtual Private Cloud (VPC) A logically isolated virtual network in the AWS cloud. You define a VPC’s IP address space from a range you select.
Subnet A segment of a VPC’s IP address range where you can place groups of isolated resources.
Internet Gateway The Amazon VPC side of a connection to the public Internet.
NAT Gateway A highly available, managed Network Address Translation (NAT) service for your resources in a private subnet to access the Internet.
Hardware VPN Connection A hardware-based VPN connection between your Amazon VPC and your datacenter, home network, or co-location facility.
Virtual Private Gateway The Amazon VPC side of a VPN connection. The Customer gateway is the customer side of a VPN connection.
Peering Connection A peering connection enables you to route traffic via private IP addresses between two peered VPCs
VPC Endpoint Enables Amazon S3 access from within your VPC without using an Internet gateway or NAT, and allows you to control the access using VPC endpoint policies.

Cloud computing is based on Virtual Private Cloud ( VPC). This is the basic foundation of the AWS platform. Any of the advanced services of AWS can not be accessed without a VPC network. You will get a logically isolated section dedicated to a virtual network platform. Through this cloud, businesses can access customer details and data in a single window. It provides innovative new business approaches.

These VPC’s are existing in the AWS roundabout. This AWS around a geographic area. It can be around the world in Amazon's clustered data centers. It is lived in that assigned geographical area only to maintain customer distribution. So that in different areas customers can not set up another VPC in another geographical area.

Yes, VPC works globally. All its components are also working globally. Obviously, they are divided into zone to crate Subnet networks.

Yes, we can use AWS VPC to enable our internet gateway. It gives permission to EC2 occurrences in VPC to directly access the internet. There are other options also.
We can also follow the given below steps:
By using hardware, virtual private network connection, and corporate data centers.
By using the internet through an internet gateway.
By using both the internet and corporate data center.
By using other VPC peering conditions.
By using other AWS.

If we want to build up our custom VPC, please follow the given below steps:
First, we need to create a virtual private cloud.
After that need to create subnets.
Now need to create an internet gateway.
Need to attach internet gateway with VPC.
Need to create a routing table.
Now add that created gateway in the new route table.
Do subnet association with the routing table.
Need to create a database server for the private subnet and a web server for the public subnet.
Need to create a new secured group of NAT.
Need to add HTTP and HTTPS inbound rules to allow traffic from private subnet IP.
Need to create elastic IP.
Tag this elastic IP with NAT.
Now deactivate the check for NAT.
Need to add this NAT in the base route table initially.

The answer is no. We can find out about it from the AWS management console in a by-fault VPC. AWS used to create one by default VPC. We need to create a default subnet for each available zone. Default VPC will be connected to the internet through the gateway automatically.
