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...

Kerberos protocol is a network authentication protocol that allows individuals communicating over a non-secure network to prove their identity to one another in a secure manner.
Developed by MIT in the 1980s
Uses symmetric key cryptography
Involves a Key Distribution Center (KDC)
Prevents eavesdropping and replay attacks
Three-way handshake is a method used in TCP/IP network to establish a connection between a client and a server.
Client sends a SYN (synchronize) packet to the server to initiate a connection
Server responds with a SYN-ACK (synchronize-acknowledgment) packet to acknowledge the request
Client sends an ACK (acknowledgment) packet back to the server to confirm the connection
TLS (Transport Layer Security) is a protocol that ensures privacy and data integrity between communicating applications.
TLS encrypts data to ensure confidentiality during transmission.
It uses cryptographic algorithms to authenticate the parties involved in the communication.
TLS also provides mechanisms for data integrity to prevent tampering.
Handshake process involves negotiation of encryption algorithms and exchange o...

UDP (User Datagram Protocol) is a con...
A diode is a semiconductor device that allows current to flow in one direction only. Resistance is the measure of opposition to the flow of current in a material.
Diode is a two-terminal electronic component that conducts current primarily in one direction.
It has a low resistance in the forward direction and high resistance in the reverse direction.
Resistance is measured in ohms and is the property of a material that op...
BGP stands for Border Gateway Protocol, a routing protocol used to exchange routing information between different autonomous systems on the internet.
BGP is used to make routing decisions based on network policies, rules, and paths.
It is a path vector protocol that uses TCP as its transport protocol.
BGP is commonly used by Internet Service Providers (ISPs) to connect their networks and exchange routing information.
BGP h...
