Dhunguru Music Interview Questions and Answers

Trunk is used to carry multiple VLANs between switches, while access is used to connect end devices to the network.

• Trunk is used to connect switches together and carry multiple VLANs

• Access is used to connect end devices like computers, printers, etc. to the network

• Trunk ports are configured with VLAN tagging, while access ports are not

• Examples of trunk ports are inter-switch links, while examples of access ports are ports connected to end devices

Port-based security involves controlling access to network resources based on the physical port of the device.

• Port security can be implemented by limiting the number of MAC addresses that can be learned on a port.

• It can also involve configuring the port to only allow traffic from specific VLANs.

• Port security can be used to prevent unauthorized access to the network by limiting the devices that can connect to it.

• It can also be used to prevent rogue devices from being connected...read more

To convert access into trunk, we need to configure the switch port as a trunk port.

• Configure the switch port as a trunk port using the 'switchport mode trunk' command.

• Verify the trunk configuration using the 'show interfaces trunk' command.

• Ensure that the VLANs allowed on the trunk are configured using the 'switchport trunk allowed vlan' command.

• Ensure that the native VLAN is configured using the 'switchport trunk native vlan' command.

Load balancer distributes incoming network traffic across multiple servers to improve performance and availability.

• Load balancer acts as a reverse proxy server

• It distributes traffic based on various algorithms such as round-robin, least connections, IP hash, etc.

• It monitors server health and redirects traffic to healthy servers

• It can be hardware-based or software-based

• Examples of load balancers include F5, HAProxy, Nginx, etc.

Access is a port that allows a single VLAN while trunk is a port that allows multiple VLANs.

• Access ports are used to connect end devices like computers, printers, etc. to the network.

• Trunk ports are used to connect switches to each other and carry traffic for multiple VLANs.

• Access ports are assigned to a single VLAN while trunk ports can carry traffic for multiple VLANs.

• Access ports do not tag frames while trunk ports tag frames with VLAN IDs.

• Examples of access ports include ...read more

LAN is a local area network that connects devices within a limited area, while WAN is a wide area network that connects devices over a large geographical area.

• LAN is typically used in homes, offices, or schools, while WAN is used to connect different LANs across cities, countries, or even continents.

• LAN has a higher data transfer rate and lower latency compared to WAN.

• Examples of LAN technologies include Ethernet, Wi-Fi, and Bluetooth, while WAN technologies include leased li...read more
