(5 Questions)
- Q1. What are different fiber optic cables?
- Ans.
Different types of fiber optic cables include single-mode, multi-mode, and plastic optical fiber.
Single-mode fiber optic cables have a small core size and are used for long-distance communication.
Multi-mode fiber optic cables have a larger core size and are used for shorter distances.
Plastic optical fiber is made of plastic and is often used for short-distance applications like home networks.
Other types include polariz
- Q2. What is DNS use for?
- Ans.
DNS is used to translate domain names into IP addresses.
DNS stands for Domain Name System.
It helps users access websites by translating human-readable domain names (e.g. www.google.com) into IP addresses (e.g. 172.217.3.206).
DNS also helps in email delivery by translating domain names into IP addresses to locate mail servers.
It plays a crucial role in network communication and internet functionality.
- Q3. Difference between network layer and data link layer?
- Ans.
Network layer deals with logical addressing and routing of data packets, while data link layer deals with physical addressing and error detection/correction.
Network layer operates at Layer 3 of OSI model, while data link layer operates at Layer 2.
Network layer uses logical addressing (IP addresses) for routing packets, while data link layer uses physical addressing (MAC addresses) for local delivery.
Examples of network...
- Q4. What is subnetting?
- Ans.
Subnetting is the process of dividing a network into smaller sub-networks to improve performance and security.
Subnetting helps in optimizing network traffic by breaking down a large network into smaller, more manageable sub-networks.
It allows for better organization and management of IP addresses within a network.
Subnetting also enhances network security by creating boundaries between different segments of a network.
Ex...
- Q5. What are Vlans . Explain with examples.
- Ans.
VLANs (Virtual Local Area Networks) are used to segment a network into multiple isolated networks for security and efficiency.
VLANs allow for logical segmentation of a network, isolating traffic within each VLAN.
They can improve network performance by reducing broadcast traffic.
VLANs can enhance network security by restricting access to resources based on VLAN membership.
Examples of VLANs include separating voice traff...

- Q1. Packet flow of fortigate device
- Ans.
Packet flow in Fortigate device involves ingress, inspection, decision making, and egress stages.
Ingress stage: packets enter the Fortigate device through interfaces
Inspection stage: packets are inspected based on security policies and rules
Decision making stage: Fortigate device determines actions to take on packets (allow, deny, 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...

- Ans.
Optical fibre is a thin, flexible, transparent fibre made of glass or plastic that can transmit light signals over long distances.
Optical fibre is used in telecommunications to transmit data at high speeds.
It consists of a core, which carries the light signals, surrounded by a cladding layer that reflects the light back into the core.
The core and cladding are protected by a buffer coating to prevent damage.
