Genpact Network Engineer Interview Questions and Answers

Q1. What is hsrp,vrrp
Ans. 
HSRP (Hot Standby Router Protocol) and VRRP (Virtual Router Redundancy Protocol) are network protocols used for providing high availability in routing.
• HSRP and VRRP are used to provide redundancy for routers in a network.

• They allow for automatic failover in case of a router failure.

• HSRP is a Cisco proprietary protocol, while VRRP is an open standard protocol.

• Both protocols use a virtual IP address that clients use as t...read more

Q2. Difference between unicasting, Multicasting, Broadcasting.
Ans. 
Unicasting sends data from one sender to one receiver, Multicasting sends data from one sender to multiple receivers, Broadcasting sends data from one sender to all receivers in the network.
• Unicasting is one-to-one communication.

• Multicasting is one-to-many communication.

• Broadcasting is one-to-all communication.

• Unicasting is used in TCP connections.

• Multicasting is used in streaming video or audio to multiple users.

• Broad...read more

Q2. What is bgp path selection process
Ans. 
BGP path selection process determines the best path for routing based on various attributes.
• BGP selects the path with the highest weight attribute first

• If weights are the same, BGP looks at the local preference attribute

• Next, BGP considers the AS path length

• BGP then checks the origin code attribute

• After that, BGP looks at the MED (Multi-Exit Discriminator) attribute

• If all else is equal, BGP chooses the path with the lo...read more

Q3. What is stub area
Ans. 
A stub area is an OSPF area that does not contain external routes.
• Stub areas reduce the amount of routing information exchanged within an OSPF network.

• Stub areas use a default route to reach external networks.

• Stub areas are commonly used to reduce the size of the OSPF database and improve network performance.

Q4. What is stp? how to work.
Ans. 
STP stands for Spanning Tree Protocol, used in network environments to prevent loops and ensure redundant paths are utilized efficiently.
• STP is a network protocol used to prevent loops in Ethernet networks.

• It works by selecting a single path for data traffic while blocking redundant paths.

• STP elects a root bridge and calculates the shortest path to each network segment.

• If a link fails, STP recalculates the network topo...read more
