Question

Accepted Answer

A network engineer interview question covering topics like DDOS, VLAN, VTP, access and trunk ports, Intervlan routing, and traceroute/MTR.

DDOS stands for Distributed Denial of Service, which is a type of cyber attack that floods a network or server with traffic to make it unavailable to users.
TCPDUMP is a command-line packet analyzer that can capture and display network traffic. It can be used to identify the source and type of traffic during a DDOS attack.
VLAN stands for Virtual Local Area Network, which is a logical grouping of devices on a network based on factors like department, function, or location.
VTP stands for VLAN Trunking Protocol, which is a Cisco proprietary protocol used to manage VLANs across a network.
Access ports are used to connect end devices like computers or printers to a VLAN, while trunk ports are used to carry traffic between VLANs.
Intervlan routing is the process of routing traffic between VLANs using a layer 3 device like a router or layer 3 switch.
Traceroute and MTR are network diagnostic tools used to trace the path of packets through a network and identify any issues or delays.
