Wrong Questions on Practice Tests
Hello All I'm starting to get really frustrated with EXAM Cram 2. I have stumbled onto quite a few questions that I believe they are wrong about and I'm worried the actual test may cause me to make the same mistakes. Let me give you a sample question and perhaps you can help.
Which of the following devices is associated with the Physical layer?
NIC Card
Router
Switch
Fiber Optic Cable
Ok Obviously I picked NIC card because it is a device that operates at the Physical and Data link Layer. Well according to the answer its supposed to be the Fiber Cable. WTF!!!! since when is cabling a device???? Am I crazy or did they word this wrong?

As quoted from Wikipedia:
The Physical layer defines all the electrical and physical specifications for devices. In particular, it defines the relationship between a device and a physical medium. This includes the layout of pins, voltages, cable specifications, Hubs, repeaters, network adapters, Host Bus Adapters (HBAs used in Storage Area Networks) and more.
I can see where the word Device may have thrown you off. But the definition of a device at Dictionary.com could include a fiber cable.
Since all other answers listed work at the Data Link layer or higher, the only logical choice is the fiber optic cable.

The Net+ exams will test you on that sort of thing, as will the CCNA. Make sure you get that one down. I don't recommend the Exam Cram books as your first source, use them as a second resouce.

Try not to look at this exam as a "semantics" or "grammar" quiz - that's what Micrsoft tests are for.
Look at everything with the "network" concept in mind. That should help you understand what they are asking you. Pick the "most correct" or "best" answer. If you still have trouble, grab something other than the Exam Cram and see if you can grasp the material a little better. Better yet, check out the TechNotes here:
