It provides port scanning and host discovery.
What is nmap?
It is used for encrypted web traffic using TLS/SSL (Protocol and Port).
What is HTTPS-443?
This routing protocol is essential for Internet routing and is the only exterior routing protocol.
What is BGP (Border Gateway Protocol)?
A network segment that isolates public‑facing services from an organization’s internal network so external users can reach those services without directly exposing internal hosts.
What is a DMZ (Screened Subnet)?
A topology with a direct, dedicated link between exactly two devices for simple, high‑performance connectivity without intermediate switching or shared medium.
What is Point-to-Point?
A command that captures and inspects packet traffic in a Linux environment.
What is tcpdump?
Designed to automatically distribute IP addresses in a network. (Protocol and Ports)
What is DHCP-67/68?
Largely deprecated, this routing protocol is slow to converge and is limited to 15 hops.
What is RIP (Routing Information Protocol)?
An ordered set of permit and deny statements that a network device evaluates top to bottom to allow or block specific traffic flows based on packet fields such as source and destination addresses, protocol, and port numbers.
What is an ACL (Access Control List)?
A network topology in which all endpoints connect to a central hub device that forwards traffic.
What is Star/Hub and Spoke?
This command maps a packet's path and helps identify hop-level latency. It has different names in Windows/Linux.
What is traceroute/tracert?
It exists so we don't have to remember every IP address on the internet. (Protocol and Port)
What is DNS-53?
A Cisco-developed hybrid routing protocol, it uses dynamic metrics for routing decisions.
What is EIGRP (Enhanced Interior Gateway Routing Protocol)?
A device that consolidates multiple network security functions into a single appliance to simplify protection and administration, inspecting traffic at multiple layers as it passes through the appliance.
What is a UTM (Unified Threat Management) device?
A topology where every node connects directly to many or all other nodes, so multiple redundant paths exist, and no single link failure necessarily isolates a node.
What is a Mesh network?
It queries DNS records and helps troubleshoot name resolutions. It has different names in Windows/Linux.
What is nslookup/dig?
It is an application-layer protocol designed for transferring files between a client and a server. (Protocol and Ports)
What is FTP-20/21?
This interior protocol uses a link-state design coupled with Dijkstra's loop-free algorithm.
What is OSPF (Open Shortest Path First)?
An IEEE standard for port-based network access control that authenticates devices before granting them access to a LAN or WLAN.
What is 802.1x?
A two‑layer fabric with a collapsed core that provides predictable east‑west bandwidth and consistent latency for modern datacenters.
What is a Spine and Leaf?
The only QB in NFL history to have 0 completions in an entire game.
