Infosys Consulting Interview Questions, Process, and Tips

BGP attributes are characteristics used to influence routing decisions in Border Gateway Protocol.

• BGP attributes are used to determine the best path for routing traffic.

• Some common BGP attributes include AS Path, Next Hop, Local Preference, and MED.

• AS Path attribute shows the path of autonomous systems that the route has traversed.

• Next Hop attribute indicates the IP address to reach the next hop for the route.

• Local Pre...read more

RB stands for Routing and Bridging. It refers to the process of forwarding data packets between networks.

• RB is a fundamental concept in networking.

• It involves the routing of data packets between different networks.

• Bridging refers to the process of connecting two or more network segments together.

• RB helps in efficient data transmission and network connectivity.

• Example: RB is used in routers to determine the best path fo

RIP version 1 is a classful routing protocol while RIP version 2 is a classless routing protocol.

• RIP version 1 does not support VLSM (Variable Length Subnet Masking) while RIP version 2 does.

• RIP version 1 does not support authentication while RIP version 2 does.

• RIP version 1 broadcasts routing updates using the destination IP address 255.255.255.255 while RIP version 2 uses multicast address 224.0.0.9.

• RIP version 1 sen...read more

STP (Spanning Tree Protocol) is a network protocol that prevents loops in Ethernet networks by creating a loop-free logical topology.

• STP is used to prevent broadcast storms and network congestion caused by loops.

• It works by electing a root bridge and calculating the shortest path to the root bridge for each network segment.

• STP uses Bridge Protocol Data Units (BPDU) to exchange information between switches.

• It employs a ...read more

The laws of thermodynamics describe the behavior of energy in a system.

• First law: Energy cannot be created or destroyed, only transferred or converted.

• Second law: Entropy (disorder) always increases in a closed system.

• Third law: As temperature approaches absolute zero, entropy approaches a minimum.

• Examples: A car engine converting fuel into motion, a refrigerator cooling a room, a power plant generating electricity.

2 stroke engines have a power stroke in every revolution while 4 stroke engines have a power stroke in every other revolution.

• 2 stroke engines have a simpler design and are lighter than 4 stroke engines.

• 2 stroke engines have a higher power-to-weight ratio than 4 stroke engines.

• 4 stroke engines are more fuel efficient and have a longer lifespan than 2 stroke engines.

• 2 stroke engines are commonly used in small power tool...read more
