I applied via Naukri.com and was interviewed in Apr 2023. There were 2 interview rounds.
Fiber is a high-speed transmission medium that uses thin strands of glass or plastic to transmit data.
Fiber optic cables are used in telecommunications to transmit data over long distances at high speeds.
Fiber offers advantages such as high bandwidth, low latency, and immunity to electromagnetic interference.
Fiber optic technology is used in various applications including internet connectivity, telephony, and cable tel...
IP stands for Internet Protocol, a set of rules governing the format of data sent over the internet.
IP is responsible for routing data packets between devices on the internet.
It assigns a unique address to each device connected to the internet.
There are two versions of IP - IPv4 and IPv6.
IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses.
IP is a layer 3 protocol in the OSI model.
Examples of IP-based protocols
OSI Models are a conceptual framework that standardizes communication protocols between different systems.
OSI stands for Open Systems Interconnection
It has 7 layers, each with a specific function
Layers are numbered from 1 to 7, with 1 being the lowest and 7 being the highest
Each layer communicates with the layer above and below it
Examples of layers include physical layer, data link layer, network layer, transport layer...
The data transfer happens at the Transport layer.
The Transport layer is responsible for end-to-end communication between devices.
It ensures reliable data transfer and error correction.
Examples of protocols at this layer include TCP and UDP.
I applied via Superset and was interviewed in Apr 2022. There were 3 interview rounds.
A network is a group of interconnected devices that communicate with each other. OSI layers are a model for understanding network communication.
OSI layers are a conceptual model for understanding how data is transmitted over a network.
There are seven layers in the OSI model, each with a specific function.
The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Each layer communica...
TCP is a protocol used for reliable transmission of data over networks.
TCP stands for Transmission Control Protocol.
It is a connection-oriented protocol that ensures reliable delivery of data packets.
TCP uses a three-way handshake to establish a connection between two devices.
It provides flow control, congestion control, and error detection and correction mechanisms.
TCP is used for applications that require reliable da...
IPv4 uses 32-bit addresses while IPv6 uses 128-bit addresses.
IPv4 allows for approximately 4.3 billion unique addresses while IPv6 allows for approximately 340 undecillion unique addresses.
IPv6 includes built-in security features such as IPsec while IPv4 requires additional security protocols.
IPv6 also includes features such as stateless address autoconfiguration and multicast addressing.
IPv4 headers are 20 bytes long ...
There are several types of networks, including LAN, WAN, MAN, WLAN, and VPN.
LAN (Local Area Network) - a network that connects devices within a small area, such as a home or office.
WAN (Wide Area Network) - a network that connects devices across a large geographical area, such as the internet.
MAN (Metropolitan Area Network) - a network that connects devices within a city or metropolitan area.
WLAN (Wireless Local Area N...

STP loop prevention is achieved by blocking redundant paths in a network to prevent loops.
STP (Spanning Tree Protocol) identifies redundant paths in a network
STP selects a root bridge to be the central point of the network
STP blocks certain ports to prevent loops while still allowing for redundancy
If a link fails, STP will unblock a previously blocked port to maintain connectivity
I applied via Company Website and was interviewed in Jul 2024. There were 3 interview rounds.
DNS stands for Domain Name System, which translates domain names to IP addresses.
DNS is like a phone book for the internet, translating human-readable domain names (like google.com) to IP addresses (like 172.217.3.206).
It helps users access websites by typing in easy-to-remember domain names instead of complex IP addresses.
DNS servers store records of domain names and their corresponding IP addresses, allowing for effi...
DHCP stands for Dynamic Host Configuration Protocol, used to automatically assign IP addresses to devices on a network.
DHCP eliminates the need for manual IP address configuration on each device
It assigns IP addresses dynamically, allowing for efficient use of available addresses
DHCP servers lease IP addresses to devices for a specific period of time
DHCP also provides other network configuration information, such as su...

DHCP assigns IP addresses to devices on a network automatically
DHCP server assigns IP addresses to devices on the network
DHCP clients request IP addresses from the DHCP server
DHCP uses a lease mechanism to manage IP address assignments
DHCP reduces the administrative burden of manually assigning IP addresses
DNS is a system that translates domain names to IP addresses to locate resources on the internet.
DNS resolves domain names to IP addresses
DNS operates through a distributed database system
DNS uses hierarchical structure with top-level domains like .com, .org, etc.
DNS queries are resolved through recursive and iterative processes
