True Value Homes Interview Questions and Answers

VLAN is a virtual LAN that separates broadcast domains, access port connects end devices to a VLAN, trunk port carries traffic for multiple VLANs.

• VLAN stands for Virtual Local Area Network and is used to separate broadcast domains within a network.

• Access port is used to connect end devices like computers or printers to a specific VLAN.

• Trunk port is used to carry traffic for multiple VLANs over a single link.

• VLANs help in segmenting network traffic for security, performance, a...read more

L3 switches operate at the network layer and can perform routing functions, while L2 switches operate at the data link layer and only switch packets based on MAC addresses.

• L3 switches operate at the network layer and can route traffic based on IP addresses.

• L2 switches operate at the data link layer and switch packets based on MAC addresses.

• L3 switches are capable of performing routing functions, while L2 switches are not.

• L3 switches are more complex and expensive compared to ...read more

Routers connect multiple networks together, while switches connect devices within a single network.

• Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).

• Routers use IP addresses to forward data between networks, while switches use MAC addresses to forward data within a network.

• Routers determine the best path for data packets based on routing tables, while switches use MAC address tables to forward data to the ...read more

L2 switches operate at the data link layer and use MAC addresses to forward packets, while L3 switches operate at the network layer and use IP addresses.

• L2 switches operate at the data link layer of the OSI model.

• L2 switches use MAC addresses to forward packets within the same network.

• L3 switches operate at the network layer of the OSI model.

• L3 switches use IP addresses to make routing decisions between different networks.

• L3 switches are capable of routing packets between dif...read more

A MAC address is a unique identifier assigned to network interfaces for communications on a network.

• MAC stands for Media Access Control

• MAC addresses are 48 bits long

• They are usually represented in hexadecimal format, like 00:1A:2B:3C:4D:5E

There are 5 types of IP classes: A, B, C, D, and E.

• Class A: Used for large networks with over 16 million hosts. Example: 10.0.0.0

• Class B: Used for medium-sized networks with up to 65,000 hosts. Example: 172.16.0.0

• Class C: Used for small networks with up to 254 hosts. Example: 192.168.0.0

• Class D: Reserved for multicast addresses. Example: 224.0.0.0

• Class E: Reserved for experimental use. Example: 240.0.0.0

BGP stands for Border Gateway Protocol, a routing protocol used to exchange routing information between different networks. AD value is the administrative distance, a measure of the trustworthiness of a routing information source.

• BGP is a standardized exterior gateway protocol used to exchange routing information between different autonomous systems.

• AD value is a numerical value assigned to a routing protocol to indicate its trustworthiness in providing routing information.

• Lo...read more
