Get ready for your AWS VPC interview with essential questions. Learn key concepts, configurations, and strategies to confidently navigate AWS Virtual Private Cloud discussions.
1. Why Amazon decided to develop VPC.
Around the globe, Amazon has a large number of physical data centres. They were eager to start building virtual data centres now. These data centres could not have functioned without virtual networks and the ability to access virtual networks. They have developed a Virtual Private Cloud (VPC) to oversee this virtual cloud, allowing clients to access a private cloud zone within the virtual network. They could still use other Amazon services.
2. What features does the AWS VPC offer?
The capabilities listed below are available with this AWS VPC:
- Address books for IPv4 and IPv6.
- Internet access.
- Establishment of a subnet.
- Flow tables.
- Flexible IP addresses.
- Security of networks and subnets.
- Extra services related to networking.

4. What is VPC in AWS?
The Amazon Virtual Private Cloud, or VPC, is a safe, private network that lets you use AWS services in a virtual setting.
5. What is AWS VPC Peering?
By connecting two VPCs through VPC peering, you can connect instances within the connected VPCs to communicate with one another as though they were on the same network.
6. How can I set up an Amazon VPC?
By going to the VPC Dashboard in the AWS Management Console and following the setup tutorial for a new VPC, you can construct a virtual private cloud (VPC) on AWS.
7. What exactly is a security group in an AWS virtual private cloud?
In response, a security group governs incoming and outgoing traffic in a VPC by acting as a virtual firewall according to rules that the user has set.

8. Why would you want to connect a virtual private cloud (VPC) to an internet gateway?
Connected to a virtual private cloud (VPC) is an internet gateway that permits traffic to and from the internet.
9. What do domain name resolution and IP addressing serve?
Computers communicate with one another via IP addressing, most especially IP version 4.
10. Could you please explain what VPC endpoints are and the functions they enable?
You can link private IP addresses to AWS public services through VPC endpoints.
11. What are the critical elements of an AWS VPC?
Essential components of an Amazon Virtual Private Cloud (VPC) include subnets, route tables, internet gateways, network address translation (NAT) gateways, security groups, and network access control lists (ACLs).
12. A subnet is a network segment within an AWS VPC.
Within your VPC, a subnet is a group of IP addresses that you can use to assign resources to Amazon. Subnets have an association with particular Availability Zones and can be either private or public.
13. What does a NAT gateway in an Amazon VPC mean?
AWS’s managed network address translation (NAT) service, known as a NAT gateway, permits instances located in private subnets to start outgoing internet traffic while blocking incoming traffic from getting through.

14. In an AWS VPC, what is a route table?
The set of guidelines known as routes that specify the direction of network traffic inside a virtual private cloud (VPC) is known as a route table. It is in charge of traffic routing between subnets and the internet.
15. What does an Amazon VPC internet gateway mean?
An internet gateway is an AWS service that enables communication between instances within your VPC and the internet. It is redundant, highly available, and horizontally expandable.
16. How is the internet connection to your VPC made?
You need to install an Internet gateway and alter the route table to route traffic intended for the Internet through the Internet gateway in order to connect your VPC to the Internet.
17. How is an IP address represented, and what is its structure?
There is a binary object known as a dotted decimal notation that represents the structure of an IP address. Eight numbers, any of which might be one or zero, make up an IP address.
18. What are sub-net masks and how are they utilized in IP addresses?
Subnet masks identify the bit that represents the network and the bit that represents the host ID. Each IP address has a host ID and a network ID.
The first three octets of a 24-bit sub-net mask, which represents the network ID, and the final octet, which represents the host ID, indicate the network ID.

19. How does classless inter-domain routing (CIDR) operate?
CIDR is a routing technique that maximizes the number of required networks and hosts. It assigns addresses to subnets using variable-length subnet masks.
20. What is a VPC endpoint in an Amazon VPC?
In response, you can bypass the necessity for an internet gateway, NAT device, VPN, or AWS Direct Connect by making use of a VPC endpoint to privately access AWS services within your VPC.
21. What is an ACL, or network access control list, in an AWS virtual private cloud?
In order to manage traffic entering and leaving one or more subnets, your VPC can add an optional network access control list (ACL) layer of protection.
22. What sets apart a subnet mask of classes A, B, and C from each other?
With its 16-bit sub-net mask, Class B networks can have no more than 65,536 valid addresses. Class A permits up to 126 networks with several hosts. Class C has more networks available but fewer addresses per network due to its 24-bit sub-net mask.
23. In the firewall rule table, where is the target IP located?
In the firewall rule table, the destination IP is the client’s IP address.
24. What are the specific applications of private IP address ranges?
A company’s private IP address ranges are not meant for usage on the open Internet; they are meant for internal use only. By changing the length of subnet masks and making sure that data transferred out of a network ends up on the Internet or another subnet, they maximize IP space.
25. What functions do each of a VPC’s components serve?
Two components of a virtual private network (VPC)—the client gateway and the virtual private gateway—are responsible for creating VPN connections to remote locations, such as company headquarters or data centers.
