| Spotted this on cert-cities and thought I'd share it...
edit: For some unknown and weird reason EN filters out cert-cities.com. Just go there (without the dash) and you'll find it. It's in "Tips Central"
"Are You Ready for Cisco's CCNA Exam? Make sure with these top 10 study tips from Karen Robertson-Kidd"
Why dump sites are allowed but a very reputable site like cert-cities gets filtered is beyond me. | |

“Network Interface Cards (NICs): There's a tremendous debate over whether these are devices that work at Layer 1 (by virtue of passing on bits into the network stream) or Layer 2 (for holding the Media Access Control -- MAC -- address and the software drivers) . Don't get caught up in this debate when you take the exam. As far as Cisco is concerned, NICs operate at Layer 1 of the OSI Model. Period. “
The Cisco Networking Academy Program Semester 1, chapter 3.1 (Basic LAN Devices) states:
“NICs are considered Layer 2 devices because each individual NIC throughout the world carries a unique code, called a Media Access Control (MAC) address. This address is used to control data communication for the host on the network.”
Karen’s statement has caused me some doubt.
I’ve always considered the NIC to be, primarily, a Layer 2 device (MAC address blah blah) which also operates at Layer 1.
I.e. if some random person came up to me in the street and asked me “At what OSI Layer does a NIC card operate?” I would have quite happily replied “Layer 2”.
The last sentence in Karen’s statement is wrong I trust? | |

I would reply "Get out more!"

| But he’s already out; you don’t get much more out that in the street. Unless its one of them newfangled American style “indoor streets”.

| hi guys
I have a question a little easy though .
I have the redmond exam practice tests and in that the question:
Which network mask should you place on class C network to accomodate a user requirement of two subnetworks with a MAXIMUM of 35 hosts on each network ?
a. 255.255.255.192
b. 255.255.255.224
c. 255.255.255.240
d. 255.255.255.248
Now the answer as acc to them is a.
however the problem is it says a maximum of 35 so it can be less too however it should not be more as it has a maximum limit set so if we calculate taking that pressumption then we have b. as the answer.
If someone has some veiws on it please do guide me |
