DTP Trunking Modes

DTP helps switches negotiate and establish 802.1Q trunk links.
DTP is a Cisco proprietary protocol.
A switch port on a Cisco switch supports a number of DTP trunking modes.
The trunking mode defines how the port negotiates using DTP to set up a trunk link with its peer port.
DTP is configured using the switchport mode {access | dynamic {auto | desirable} | trunk} interface configuration command.

Cisco Discovery Protocol (CDP):

is a Layer 2, media-independent, and network-independent protocol that runs on Cisco devices and enables networking applications to learn about directly connected devices nearby.

This protocol facilitates the management of Cisco devices by discovering these devices, determining how they are configured, and allowing systems using different network-layer protocols to learn about each other.

The information contained in CDP advertisements varies based on the type of device and the installed version of the operating system. Some of the information that Cisco Discovery Protocol can learn includes:
•Cisco IOS version running on Cisco devices
•Hardware platform of devices
•IP addresses of interfaces on devices
•Locally connected devices advertising Cisco Discovery Protocol
•Interfaces active on Cisco devices, including encapsulation type
•Hostname
•Duplex setting
•VLAN Trunking Protocol (VTP) domain
•Native VLAN

EIGRP uses different K values to determine the best path to each destination:
Bandwidth (K1),Load (K2),Delay (K3),Reliability (K4),MTU (K5) . @ciscoAcademy
Types of ACLs

the type of ACL could be identified by the number for example An ACL numbered 700–799 would indicate that the traffic is classified and controlled based on MAC addresses.
