Network Technology Cisco Knowledge Point
1. What is the difference between a star topology and a mesh topology?
Star topology: easy to implement, easy to expand, easy to troubleshoot, but the central node pressure is high, the networking cost is high, the node is directly connected to the central node
Mesh topology: the opposite of a star topology
2, a brief description of IEEE802.3u, IEEE802.3z standard
IEEE802.3u: 100m/s Fast Ethernet Standard
IEEE802.3z: Fiber Optic Media Implements 1Gb/s Ethernet Standard
3, binary conversion: 1 2 4 8 16 32 64 128 512 1024
4. Which seven layers are the osi reference models divided into?
Application layer, presentation layer, session layer, transport layer, network layer, data link layer, physical layer
5. Which layer of data frame is it?
data link layer
6. Which layer does the router work on?
Network layer
7, the next three layers of packaging process:
The application layer is converted into binary coded data, and the TCP segment header of the segmentation data segment is transmitted, the transmission layer is added with IP, the data link layer is home MAC header, and the physical layer converts the bit stream into an electrical signal.
8, T568A, T568B line order?
A: white green, green, white orange, blue, white blue, green, white brown, brown
B: white orange, orange, white green, blue, white blue, green, white brown, brown
9. What are the six subsystems of the cabling system?
1), work area subsystem 2), horizontal subsystem 3), management subsystem
4), vertical subsystem 5), building subsystem 6), equipment room subsystem
10, material estimation N information points
Crystal head: 4N+4N 15%
Cable usage: C={0.55(L+S)+6}N
Module = information + information point 3%
11, wiring facility process
1), wall punching 2), trunking installation 3), laying cables
4), terminating the cable 5), equipment rack 6), connectivity test
12. What are the Cisco switch configuration modes?
1), user mode 2), privileged mode
3), global configuration mode 4), interface mode
13, the working principle of the switch?
1), MAC address learning 2), broadcast location data frame
3), the recipient responds to the message
4), the switch implements unicast communication
14, interface double attack, rate mismatch results
1), interface duplex: packet loss occurs when there is no match
2), rate: no match will directly break the network
If you want to passed the exam successfully. you can review with ccnp 300 360 dumps from evedumps.com that will help passed exam at first attempt. I will also recommend the wireless 300 365 exam dumps too.
