Kyndryl Network Engineer Interview Questions, Process, and Tips

NATting of firewall involves translating private IP addresses to public IP addresses for outgoing traffic.

• NAT (Network Address Translation) is used to hide private IP addresses behind a public IP address.

• It allows multiple devices on a local network to share a single public IP address.

• Types of NAT include Static NAT, Dynamic NAT, and PAT (Port Address Translation).

Subnetting is the process of dividing a network into smaller subnetworks for better organization and management.

• Subnetting helps in optimizing network performance by reducing congestion and improving security.

• It involves dividing an IP network into multiple smaller subnetworks called subnets.

• Subnet masks are used to determine which part of an IP address belongs to the network and which part belongs to the host.

VLAN stands for Virtual Local Area Network, a method of segmenting a physical network into multiple virtual networks.

• VLANs allow for better network security by isolating traffic between different groups of devices.

• They can improve network performance by reducing broadcast traffic.

• VLANs can be configured based on port, protocol, or MAC address.

• Example: VLAN 10 for finance department, VLAN 20 for marketing department.

BGP (Border Gateway Protocol) is a standardized exterior gateway protocol used to exchange routing information between different networks on the internet.

• BGP is used to make routing decisions based on network policies, rules, and paths.

• It is commonly used by Internet Service Providers (ISPs) to connect their networks.

• BGP operates on TCP port 179.

• BGP uses path vector routing algorithm to make routing decisions.

• BGP is cl

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
