Kyndryl Interview Questions, Process, and Tips

BGP is a routing protocol used to exchange routing information between different autonomous systems on the internet.

• BGP uses TCP port 179 for communication.

• BGP routers exchange routing information through BGP update messages.

• BGP routers establish neighbor relationships to exchange routing information.

• BGP uses path attributes to determine the best route to a destination.

• BGP can be configured to influence routing decisio

STP (Spanning Tree Protocol) prevents network loops by blocking redundant paths and selecting the shortest path.

• STP is a protocol used to prevent network loops in a switched network.

• It works by blocking redundant paths and selecting the shortest path.

• STP uses a timer called Hello Time to send messages between switches to detect changes in the network topology.

• If a switch detects a change, it sends a BPDU (Bridge Protoc...read more

SSL VPN and STS VPN are two types of VPNs. Phase 1 involves authentication and key exchange, while phase 2 establishes the actual VPN connection.

• SSL VPN uses SSL/TLS protocol for encryption, while STS VPN uses IPSec protocol.

• Phase 1 of both VPNs involves authentication and key exchange.

• In SSL VPN, phase 1 uses SSL/TLS handshake to authenticate and establish a secure channel.

• In STS VPN, phase 1 uses IKE (Internet Key Ex...read more

To link load balance on Palo Alto, configure a virtual router and create a load balancing profile.

• Configure a virtual router with multiple interfaces

• Create a load balancing profile with the desired algorithm (round-robin, least connections, etc.)

• Apply the load balancing profile to the virtual router's interfaces

• Configure the servers' default gateway to be the virtual router's IP address

SD-WAN stands for Software-Defined Wide Area Network, a technology that simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism.

• Utilizes software-defined networking (SDN) principles to dynamically direct traffic across the WAN

• Improves network performance, reduces costs, and enhances security

• Allows for centralized control and automation of network management task...read more
