- Q2. What is DSCP network
- Ans.
DSCP (Differentiated Services Code Point) is a network protocol used to prioritize and manage network traffic based on its importance.
DSCP is a field in the IP header that assigns a value to packets to indicate their priority
It allows network administrators to control and prioritize traffic flow
DSCP values range from 0 to 63, with higher values indicating higher priority
Different applications or services can be assigne...
- Q3. What is DNS
- Ans.
DNS stands for Domain Name System. It is a system that translates domain names into IP addresses.
DNS is like a phone book for the internet
It helps to locate websites by translating domain names into IP addresses
DNS servers store information about domain names and their corresponding IP addresses
DNS resolution can be recursive or iterative
Examples of DNS servers include Google DNS and OpenDNS
- Q4. Domian name system
- Q5. What is LAN
- Ans.
LAN stands for Local Area Network, a computer network that connects devices within a limited area such as a home, office, or building.
LAN is a type of network that connects devices within a limited area
It is commonly used in homes, offices, and buildings
LAN can be wired or wireless
Devices on a LAN can communicate with each other directly
Examples of LAN technologies include Ethernet and Wi-Fi
- Q6. Local area network
- Q7. What is WLN
- Ans.
WLN stands for Wireless Local Network, a type of network that allows devices to connect wirelessly within a limited area.
WLN is also known as WLAN (Wireless Local Area Network)
It uses radio waves to transmit data between devices
Common examples of WLN include Wi-Fi networks in homes, offices, and public places
- Q8. Wide area network
- Q9. What is ip
- Ans.
IP stands for Internet Protocol. It is a set of rules that governs the format of data packets sent over a network.
IP is a fundamental protocol in computer networking.
It provides the addressing scheme used to identify devices on a network.
IP packets contain both the source and destination IP addresses.
IPv4 and IPv6 are the two main versions of IP.
IP is responsible for routing packets across different networks.
- Q10. Internet protocal
- Q11. What is PAL
- Ans.
PAL stands for Phase Alternating Line, a color encoding system used in analog television systems.
PAL is used in countries like Europe, Australia, and parts of Asia.
PAL has a higher resolution and better color reproduction than NTSC.
PAL uses 50 Hz as the frequency for the alternating current, while NTSC uses 60 Hz.
PAL signals are not compatible with NTSC signals, and vice versa.
- Q12. Pravite area network
- Q13. What is topologies
- Ans.
Topologies refer to the physical or logical layout of a network, determining how devices are connected and communicate with each other.
Topologies can be classified into physical and logical topologies.
Physical topologies describe the physical arrangement of devices and cables.
Common physical topologies include bus, star, ring, and mesh.
Logical topologies describe how data flows in a network, regardless of the physical ...
- Q14. Ring topological Mesh topologies star topologies Etc.

Egress stage: packets exit the Fortigate device through interfaces
- Q2. What is SD WAN
- Ans.
SD WAN stands for Software-Defined Wide Area Network, a technology that simplifies the management and operation of a WAN by separating the networking hardware from its control mechanism.
SD WAN utilizes software-defined networking (SDN) concepts to dynamically route traffic across the WAN based on real-time data and application requirements.
It allows for centralized control and management of network traffic, providing i...

- Q1. What do you know about routing?
- Ans.
Routing is the process of selecting the best path for network traffic to reach its destination.
Routing involves determining the optimal path for data packets to travel from the source to the destination.
Routers use routing tables to make decisions on how to forward packets based on destination IP addresses.
There are different types of routing protocols such as RIP, OSPF, EIGRP, and BGP.
Static routing involves manually ...
- Q2. What do you know about switching?
- Ans.
Switching is a networking technique used to forward data packets between devices on a computer network.
Switching involves the process of receiving, analyzing, and forwarding data packets within a network.
Switches operate at Layer 2 (Data Link Layer) of the OSI model.
Switches use MAC addresses to determine the destination of data packets.
Switches create separate collision domains and broadcast domains, improving network...
