Meridian Infotech Interview Questions and Answers

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.

• Routing protocols like OSPF and BGP are used to exchange routing information between routers.

• Dynamic routing allow...read more

Switching is a networking technique that forwards data packets between devices on a computer network.

• Switching is used to connect devices within a local area network (LAN) or between multiple LANs.

• It operates at the data link layer (Layer 2) of the OSI model.

• Switches use MAC addresses to determine where to forward data packets.

• Switching increases network performance by reducing congestion and improving bandwidth utiliz

Spanning Tree Protocol is a network protocol that ensures a loop-free topology for Ethernet networks.

• Prevents loops in Ethernet networks by blocking redundant paths

• Designated switches are elected to forward traffic on each segment

• Uses Bridge Protocol Data Units (BPDUs) to exchange information between switches

VLAN stands for Virtual Local Area Network. It is used to logically segment a network to improve performance, security, and management.

• VLANs are used to separate broadcast domains in a network.

• They can be used to group devices based on department, function, or security requirements.

• VLANs can help reduce network congestion and improve overall network performance.

• They are commonly used in enterprise networks to isolate t...read more

DHCP is a network protocol that automatically assigns IP addresses to devices on a network. DORA process involves Discover, Offer, Request, Acknowledge.

• DHCP stands for Dynamic Host Configuration Protocol

• DORA process includes Discover, Offer, Request, Acknowledge

• Discover: Client broadcasts a request for IP address

• Offer: DHCP server offers an IP address to the client

• Request: Client requests the offered IP address

• Acknowle...read more

Mac binding is a security feature that associates a specific MAC address with a specific IP address on a network.

• Mac binding is used to ensure that only devices with specific MAC addresses can access the network.

• It helps prevent unauthorized devices from connecting to the network.

• Mac binding is commonly used in home networks and small businesses to enhance network security.

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 a large network into smaller segments.

• It allows for better organization and management of IP addresses.

• Subnetting also enhances network security by isolating different parts of the network.

• Example: Dividing a network with IP range 192.168.1.0/24 into sm...read more

OSPF (Open Shortest Path First) is a routing protocol used to find the best path for data packets in IP networks.

• OSPF is a link-state routing protocol

• It uses Dijkstra's algorithm to calculate the shortest path

• OSPF areas are logical groupings of routers and networks sharing the same area ID

• Each OSPF router belongs to at least one area

• Areas are used to reduce the size of the link-state database and improve network scalab

Packet flow from one network to another involves routing, switching, and encapsulation.

• Packet leaves source device and enters local network.

• Local network router determines best path to destination network.

• Packet is forwarded to destination network through routers and switches.

• Destination network router delivers packet to destination device.

• Encapsulation and decapsulation processes occur at each network device.

• Example: ...read more
