This is a method of information trade wherein two conveying PCs don't utilize IPsec themselves. All things considered; the passage that is associating their LANs to the travel network makes a virtual passage. Thus, it utilizes the IPsec convention to get all correspondence that goes through it.  


Network Analyst Interview Questions and Sample Answers

What is the purpose of a subnet mask, and how does it affect network communication?

Answer: A subnet mask is used to divide an IP address into network and host portions. It determines which part of an IP address identifies the network and which part identifies individual devices on that network. Subnet masks are crucial for routing data within a network.

For example, a subnet mask of in the IP address would mean that the first three octets (192.168.1) are the network portion, and the last octet (0) identifies individual devices on that network.


What is DNS, and how does it work?

Answer: DNS (Domain Name System) is a system that translates human-friendly domain names (e.g., into IP addresses that computers can understand. It works by using a hierarchical structure of DNS servers to look up and resolve domain names to their corresponding IP addresses.

For instance, when you type "" in your web browser, DNS servers are responsible for translating it into an IP address, like, so your computer can reach the correct web server.


Explain the difference between a firewall and an IDS (Intrusion Detection System).

Answer: A firewall is a network security device that acts as a barrier between a trusted internal network and an untrusted external network, controlling incoming and outgoing traffic based on predefined rules. In contrast, an IDS is a system that monitors network traffic for suspicious activities or potential security threats. While a firewall prevents unauthorized access, an IDS detects and alerts on unusual network behavior, helping security teams respond to potential breaches.

Example: A firewall might block incoming requests to a company's internal network, except for approved services like email and web browsing, to shield against malicious attacks.


What is VLAN (Virtual Local Area Network), and why is it used?

Answer: A VLAN is a logical segmentation of a physical network into multiple virtual networks, allowing devices to communicate as if they were on the same physical network, even if they are physically separated. VLANs enhance network security, efficiency, and management by isolating traffic and reducing broadcast domains.

For example, in a large organization, VLANs can be used to separate departments like HR, Finance, and IT, ensuring that each group's data remains isolated while sharing the same physical infrastructure.


How does NAT (Network Address Translation) work, and why is it important in networking?

Answer: NAT is a technique used to modify network address information in packet headers during transit. It's commonly used in routers to allow multiple devices on a local network to share a single public IP address for internet access. NAT plays a critical role in conserving IPv4 addresses and enhancing network security by hiding internal network structures.

For instance, when a computer on a local network requests a web page, the router performs NAT to translate the private IP address of the requesting computer into the router's public IP address, ensuring the response returns to the correct device.
