How can you check to see if a fastEthernet interface on a router is connected to the fastEthernet interface on another network device?
Check the network card and the properties are listed there.
What layer of OSI model does a router operate?
Router is a Layer 3 (Network Layer)device that checks packet's IP Address at input interface & routes them to interface connected to destination network if available.
When a router does not have an interface for the destination network it sends the traffic to where?
If a router has a route in its routing table, it will have a next hop IP address and / or outbound interface. If a router does not have a route in its routing table the packet will be dropped.
What is a hop in a network?
A "hop" has to do with network routing. If you are on a particular IP network, for example 192.168.1.0, and you need to get to 192.168.4.0, data must travel through a router. A router provides interfaces to join at least two distinct networks. If your data travels through only one router to get to a different network, that network is considered to be one "hop" away. Data moving through additional networks to get to the destination network increase the hop count by one for each router. Thus, in the above example, if the first router had an interface attached to the 192.168.1.0 network, and another interface attached to 192.168.2.0; and then if the next router had an interface on 192.168.2.0 and one on 192.168.3.0; and then if the next router had an interface on 192.168.3.0 and one on 192.168.4.0; then the data would travel through --one, two, three-- routers to get to the destination network. In this case, network 192.168.4.0 would be three hops away from 192.168.1.0.
Where are firewalls commonly placed in private network?
Between the server / router and the internet router.
Who created the first network router?
Bolt Beranek and Newman company created the first router. The IMP or Interface Message processor.
The network containing router B is experiencing problems A network associate has isolated the issue in this network to router B What action can be preformed to correct the network issue?
issue the no shutdown command on interface FastEthernet 0/1
To which network device or interface does the IP address 192.168.1.254 belong?
That is normally the IP address of a router
What device connect wireless users to a wired network?
A wireless router.
What hardware or devices allow computers to communicate over a network?
You can use bluetooth, a simple wired connection, or wifi to connect your computers to a network.
The PC the routing table of which is displayed is configured correctly To which network device or interface does the IP address 192.168.1.254 belong?
router interface fa0/0
