Q1. How do u configure switch?
Ans. 
Switch configuration involves setting up VLANs, port security, QoS, and other settings to optimize network performance.
• Access the switch's command line interface (CLI) using a console cable or remote access software

• Configure VLANs to segment network traffic and improve security

• Enable port security to prevent unauthorized access to the network

• Set up Quality of Service (QoS) to prioritize network traffic and ensure criti...read more

Q2. What is L2 and L3 Switch and it's differences
Ans. 
L2 and L3 switches are network devices used for packet switching. L2 operates at the data link layer and L3 at the network layer.
• L2 switch operates at the data link layer and forwards packets based on MAC addresses

• L3 switch operates at the network layer and forwards packets based on IP addresses

• L2 switch is used for LAN networks while L3 switch is used for both LAN and WAN networks

• L2 switch is faster than L3 switch as ...read more

Q3. What is MPLS, where it is used
Ans. 
MPLS is a protocol used for efficient packet forwarding in a network. It is used in WANs and service provider networks.
• MPLS stands for Multiprotocol Label Switching

• It is used to improve the speed and efficiency of network traffic routing

• MPLS uses labels to identify the path that packets should take through the network

• It is commonly used in WANs and service provider networks to provide Quality of Service (QoS) and traff...read more

Q4. Explain about VLANS and how do we create
Ans. 
VLANs are virtual LANs that allow network administrators to group devices together based on their functions or departments.
• VLANs are used to segment a network into smaller, more manageable groups.

• They can be created using network switches or routers.

• Each VLAN has its own broadcast domain and can be configured with its own security policies.

• VLANs can be created based on different criteria such as department, location, o...read more

Q3. An electrical signal can be represented in either Thevenin form or Norton From. However, Norton representation is preferred when
Ans. 
Norton representation is preferred when the load impedance is known and fixed.
• Norton representation is preferred when the load impedance is known and fixed, as it simplifies calculations.

• Thevenin representation is preferred when the load impedance is unknown or variable.

• Norton equivalent circuits are easier to analyze in terms of current flow and power calculations.

• Thevenin equivalent circuits are easier to analyze in
