I applied via Recruitment Consulltant and was interviewed in Dec 2023. There was 1 interview round.
The OSI model is a conceptual framework that standardizes the functions of a communication system into seven different layers.
The OSI model stands for Open Systems Interconnection model.
It was developed by the International Organization for Standardization (ISO) in the 1980s.
The model is divided into seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer has specific fu...
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.
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 tree-like struct...
EIGRP is a Cisco proprietary routing protocol that uses advanced distance-vector algorithm for efficient routing in IP networks.
EIGRP stands for Enhanced Interior Gateway Routing Protocol.
It is used to exchange routing information between routers in a network.
EIGRP uses a combination of distance-vector and link-state routing protocols.
The port number for EIGRP is 88.
The TCP/IP model is a conceptual framework used to understand and describe how data is transmitted over a network.
The TCP/IP model consists of four layers: Network Interface, Internet, Transport, and Application.
Each layer has its own protocols and functions that contribute to the overall transmission of data.
The Network Interface layer handles the physical connection between devices, such as Ethernet or Wi-Fi.
The Inte...
DHCP DORA process is the sequence of steps followed by a client to obtain an IP address from a DHCP server.
DORA stands for Discover, Offer, Request, and Acknowledge.
Discover: Client broadcasts a DHCP Discover message to find available DHCP servers.
Offer: DHCP servers respond with DHCP Offer messages containing IP address lease information.
Request: Client selects one DHCP Offer and sends a DHCP Request message to reques...
VLANs are used to logically segment a network, improving security, performance, and manageability. The range of VLANs is from 1 to 4094.
VLANs provide network segmentation, allowing different groups of devices to be isolated from each other.
They enhance security by controlling access between VLANs using access control lists (ACLs).
VLANs improve network performance by reducing broadcast traffic and optimizing network tra...
Public IP is the address assigned to a device on the internet, while private IP is the address assigned to a device on a local network.
Public IP is unique and globally routable, allowing devices to communicate over the internet.
Private IP is used within a local network and is not accessible from the internet.
Public IP is assigned by the Internet Service Provider (ISP), while private IP is assigned by the local network'...
The packet flow of the dr and bdr election is the process by which routers in a network determine the designated router and backup designated router.
DR and BDR are elected in OSPF networks to reduce the amount of OSPF traffic and maintain network stability.
The election process begins with routers exchanging Hello packets to establish neighbor relationships.
Routers with higher OSPF priority or higher router ID are prefe...
BGP is a routing protocol used in large-scale networks to exchange routing information between autonomous systems.
BGP stands for Border Gateway Protocol.
It is used to connect different autonomous systems (AS) on the internet.
BGP allows routers in different ASs to exchange routing information and make informed decisions on the best paths for data transmission.
It is a path-vector protocol that considers multiple factors ...

I applied via Naukri.com and was interviewed in Aug 2023. There were 2 interview rounds.
A network is a collection of computers, servers, mainframes, network devices, and other devices connected to one another for sharing data and resources.
Networks can be wired or wireless
Networks can be local (LAN), wide area (WAN), or global (Internet)
Networks use protocols like TCP/IP for communication
VTP (VLAN Trunking Protocol) is a Cisco proprietary protocol used to manage VLAN configurations across a network. VLANs are virtual LANs that separate broadcast domains.
VTP is used to synchronize VLAN information across switches in a network
It helps in reducing the administrative overhead of manually configuring VLANs on each switch
VLANs are used to logically segment a network into separate broadcast domains
VLANs impro...
Protocol is a set of rules that govern the communication between devices in a network.
Protocol defines the format, timing, sequencing, and error checking of data transmission.
Examples of protocols include TCP/IP, HTTP, FTP, and SMTP.
Protocols ensure that devices can communicate effectively and understand each other's data.
Basic requirements of CCNA include knowledge of networking fundamentals, routing and switching, and hands-on experience with Cisco devices.
Understanding of networking fundamentals such as TCP/IP, subnetting, and OSI model
Knowledge of routing and switching concepts including VLANs, STP, and routing protocols like OSPF and EIGRP

There are multiple ways to transfer data in CCNA, including wired and wireless methods.
Data transfer methods in CCNA include Ethernet, Wi-Fi, Bluetooth, and cellular networks.
Ethernet is a common wired method used for data transfer in CCNA.
Wi-Fi allows for wireless data transfer over a local network.
Bluetooth is used for short-range wireless data transfer between devices.
Cellular networks enable data transfer over mobi
IP stands for Internet Protocol, which is a logical address used to identify devices on a network.
IP is a unique identifier assigned to each device connected to a network.
It allows devices to communicate with each other by routing data packets.
There are two versions of IP - IPv4 and IPv6.
IPv4 addresses are 32 bits long and written in decimal format (e.g. 192.168.1.1).
IPv6 addresses are 128 bits long and written in hexa...
Regarding technical questions
VPN stands for Virtual Private Network. It is a secure and encrypted connection between two devices over the internet.
VPN allows remote access to a private network over the internet
It provides security and privacy by encrypting the data transmitted over the network
VPN can be used to bypass geographical restrictions and access content not available in your region
Examples of VPN include OpenVPN, Cisco AnyConnect, and Nor
The server name is not specified. Can you please provide more context?
The question needs more information to provide a specific answer.
The server name could refer to a specific server in a network or a domain name.
Without additional context, it is impossible to provide a meaningful answer.
