CISCO Modules 1-3
What is the shortest, abbreviated version of the copy running-config startup-config command?
"copy run start"
Interface
Specialized ports on a networking device that connect to individual networks. Because routers connect networks, the ports on a router are referred to as network interfaces.
Network Interface Card (N.I.C.)
a NIC physically connects the end device to the network
End Devices
desktop computer, laptop, printer, IP phone, Wireless Tablet, TelePresence Endpoint
Which connections are specialized ports on a networking device that connect to individual networks? Port Nic Interface
Answer: Interface
Which type of network topology lets you see which end devices are connected to which intermediary devices and what media is being used? Physical Topology Logical Topology
Answer: Logical topology
Which connection physically connects the end device to the network? Port NIC Interface
Answer: NIC
Which connection physically connects the end device to the network? NIC Port Interface
Answer: NIC
Which type of network topology lets you see the actual location of intermediary devices and cable installation? Physical Topology Logical Topology
Answer: Physical topology
When data is encoded as pulses of light, which media is being used to transmit the data? wireless fiber-optic cable copper cable
Answer: fiber-optic cables
Which of the following is the name for all computers connected to a network that participate directly in network communication? servers hosts media intermediary devices
Answer: hosts
Which two devices are intermediary devices? (Choose two) hosts routers servers switches
Answer: routers & switches
Which type of network topology lets you see which end devices are connected to which intermediary devices and what media is being used?
Logical topology
Physical Port
A connector or outlet on a networking device where the media connects to an end device or another networking device
Which connections are specialized ports on a networking device that connect to individual networks? Port NIC Interface
Answer: Interface
Logical Topology Diagrams
Logical topology diagrams illustrate devices, ports, and the addressing scheme of the network, as shown in the figure. You can see which end devices are connected to which intermediary devices and what media is being used.
Privileged EXEC Mode
Mode allows access to all commands and features. The user can use any monitoring commands and execute configuration and management commands. Switch# Router#
User Exec Mode
Mode allows access to only a limited number of basic monitoring commands. It is often referred to as "view-only" mode. Switch> Router>
Which type of network topology lets you see the actual location of intermediary devices and cable installation?
Physical Topology
Device Names
Switch# configure terminal Switch(config)# hostname Sw-Floor-1 Sw-Floor-1(config)#
Why do you enter the no shutdown command?
The no shutdown command enables an interface (brings it up). This command must be used in interface configuration mode. It is useful for new interfaces and for troubleshooting
Why does the switch respond with "startup-config is not present?"
The switch responds with "startup-config is not present" because the start up configuration hasn't been saved yet.
Interface Configuration Mode
Used to configure a switch port or router network interface
Line Configuration Mode
Used to configure console, SSH, Telnet, or AUX access
Network Media
Wireless Media oooo L.A.N. media ------ W.A.N. Media ___z---z___z---
Intermediary Devices
Wireless routers, L.A.N. switch, Router, Multilayer Switch, Firewall Appliance
Physical Topology Diagrams
illustrate the physical location of intermediary devices and cable installation.
Which command will display the current contents of non-volatile random-access memory (NVRAM)?
startup-config
Topology Diagrams
they provide a visual map of how the network is connected. These are two types of topology diagrams: physical and logical.
