So every line off the two routers are Broadcast Domains because thats what routers do. They divide Broadcast Domains or BC and Swithches divide Collision Domains or CD.

so there are 5 direct lines off the two routers making answer 2 and 5 correct.

I only know answer 3 is correct because I worked with building cables for 7 years and when I had to make a connection to the router directly from a host I had to use a X-Over cable because it swaps the TxD and Rxd lines to talk back and forth.

Question 19 is a little confusing to me, but I think Im reading into it too much. if the devices are all using defaults then there are NO subnets programed and that is how there are one 1 subnet rather than 4 as I would normally guess. Am I on the right path in thinking this out?

I believe Question 6 should be 2048
/24 = 256 hosts
/25 = 512
/26 = 1024
/27 = 2048

kind of the same way ram doubles, unless this is taking into account the BC and NW addresses are not used, then i would see only 2046 HOSTS. is that the thinking on this?

You may use a crossover cable to connect two PC’s Network interfaces in order to create simple peer to peer network or to share Internet connectivity.etc..
The same method goes for a router Ethernet interface and a PC Ethernet interface by using a crossover cable as well as all end devices such as Printers.
This is a simple layer 1 concept:
1. 10/100 Ethernet cables have 8 wires, of which 4 are used for data; one pair for receiving and other pair for sending.
2. Hubs and Switches relays all the data from the Transmit pairs to the Receive pairs.
3. A crossover cable has it’s send and receive wires crossed.
4. Routers Ethernet interfaces DO NOT function as Switch or Hub interfaces. That why there functionality similar to PC interfaces in term of layer 1 functionality and signalling.
5. In general, routers and PCs cannot be connected by a straight-through cables.
6. straight-through cables used in:
Host to Switch
Host to Hub
Router to switch
Router to hub
Switch to Switch (If the Switchs has Auto-MDIX)
7. Crossover cable used in:
Host to host
Host to router
Switch to Switch (If the Switchs has no Auto-MDIX).

Notice that the cable is a “Crossover cable”.. NOT “straight trough”..

Well im confused, in the number 1 question, i think that the “connecting two devices with the same interface type at Fast Ethernet speeds” answer is wrong, because a switch with a fast ethernet port and a router wit the same port, cannot be connected with a crossover cable…

i got 100%..thank a lot man
