Ani Network Technical Support Engineer Interview Questions, Process, and Tips

OSI Model and TCP/IP Model are networking models used to understand how data is transmitted over a network.

• OSI Model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, Application.

• TCP/IP Model has 4 layers: Network Interface, Internet, Transport, Application.

• OSI Model is theoretical while TCP/IP Model is practical and widely used.

• OSI Model helps in understanding the functions of each layer in...read more

BGP is a routing protocol used to exchange routing information between different autonomous systems. STP is a protocol to prevent loops in network topology. OSPF is a link-state routing protocol. EPON and GPON OLT are technologies used in passive optical networks for fiber-to-the-home services.

• BGP (Border Gateway Protocol) is used to exchange routing information between different autonomous systems.

• STP (Spanning Tree P...read more

IP classes are a way of categorizing IP addresses based on their network and host portions.

• IP classes are divided into five classes: A, B, C, D, and E.

• Class A addresses have a first octet range of 1-126 and are used for large networks.

• Class B addresses have a first octet range of 128-191 and are used for medium-sized networks.

• Class C addresses have a first octet range of 192-223 and are used for small networks.

• Class D ...read more

A router is a networking device that forwards data packets between computer networks. A switch is a device that connects devices together on a computer network.

• A router connects multiple networks and determines the best path for data to travel between them.

• A switch connects devices on a network and directs data to the correct device.

• Routers use IP addresses to route data, while switches use MAC addresses to direct data...read more

A switch is a networking device that connects devices together and controls the flow of data between them.

• Switches operate at the data link layer of the OSI model.

• They use MAC addresses to forward data to the correct destination.

• Switches can create virtual LANs (VLANs) to segment a network.

• They can also prioritize traffic using Quality of Service (QoS) settings.

• Examples of switches include Cisco Catalyst, Juniper EX, a
