HCLTech Network Specialist Interview Questions and Answers

Updated 24 Jan 2025

Q1. What is the difference between Hot Standby Router Protocol (HSRP) and Gateway Load Balancing Protocol (GLBP)?

Ans.

HSRP provides high availability by allowing multiple routers to work together as a single virtual router, while GLBP provides load balancing and redundancy by distributing traffic across multiple routers.

  • HSRP allows for a standby router to take over in case the primary router fails, while GLBP allows for multiple routers to share the traffic load.

  • HSRP uses a virtual IP address and a virtual MAC address, while GLBP uses multiple virtual MAC addresses.

  • HSRP has a single active r...read more

Q2. If OSPF stuck in exstart stage how to trobleshoot

Ans.

Troubleshooting OSPF stuck in exstart stage

  • Check if there are any network connectivity issues

  • Verify if OSPF neighbor relationships are properly established

  • Ensure that OSPF router IDs are unique

  • Check for any mismatched OSPF parameters such as area IDs or network types

  • Verify if there are any firewall rules blocking OSPF traffic

Q3. Over view of OSPF, BGP,stp,vtp,hsrp,vrrp, wireless,packet flow

Ans.

Overview of OSPF, BGP, STP, VTP, HSRP, VRRP, wireless, packet flow

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

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

  • STP (Spanning Tree Protocol) prevents loops in Ethernet networks by blocking redundant paths

  • VTP (VLAN Trunking Protocol) manages VLAN configurations across a network

  • HSRP (Hot Standby Router Protocol...read more

Q4. What is the use of SDWAN?

Ans.

SDWAN stands for Software-Defined Wide Area Network. It is used to simplify the management and operation of a WAN by decoupling the networking hardware from its control mechanism.

  • Improves network performance by utilizing multiple connection types (MPLS, broadband, LTE) and dynamically routing traffic based on application needs

  • Enhances security by encrypting traffic and providing centralized visibility and control over network traffic

  • Reduces costs by optimizing bandwidth usage...read more

Q5. What is OMP in sdwan?

Ans.

OMP stands for Overlay Management Protocol in SD-WAN, used for communication between the SD-WAN edge devices and the SD-WAN controller.

  • OMP is responsible for exchanging control and management information between the SD-WAN edge devices and the centralized SD-WAN controller.

  • It helps in establishing and maintaining the overlay network tunnels in SD-WAN.

  • OMP is used to convey routing, policy, and configuration information between the edge devices and the controller.

  • It plays a cru...read more

Q6. Explain OSI model

Ans.

The OSI model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

  • The OSI model stands for Open Systems Interconnection model.

  • It helps in understanding how data is transferred between devices in a network.

  • Each layer has specific functions and communicates with the adjacent layers.

  • Examples of layers include physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and a...read more

Q7. Explain RSTP

Ans.

RSTP stands for Rapid Spanning Tree Protocol, a network protocol used to prevent loops in Ethernet networks.

  • RSTP is an improvement over the original Spanning Tree Protocol (STP) and converges faster in case of network changes.

  • It uses port roles (root, designated, alternate, backup) to determine the best path for data transmission.

  • RSTP also introduces the concept of edge ports and link types to optimize network performance.

  • Example: If a link fails, RSTP can quickly reconfigure...read more
