B.

A bit old:
http://www.pcguide.com/ref/mbsys/cache/structIntegrated-c.html
I believe the answer is B
I think the correct answer is B.
Ref: http://www.wisegeek.com/what-is-l3-cache.htm
In my opinion, L3 cache runs at the speed of the system bus.
i believe that the answer is B because the Server+ file says:
There are two or three levels of cache (fast processor memory). Cache speeds performance by holding most recently-used data. From fastest to slowest, and from smallest sized to largest,
they are –
l1, l2, l3
L1 is a memory bank built into the CPU, is the fastest memory in the computer
L2 Is a memory built on the motherboard, The L2 cache feeds the L1 cache, and its memory is slower than L1 memory
L3 Is a memory bank built into the motherboard, The L3 cache feeds the L2 cache and its memory is typically slower than the L2 memory.
answer is D
Answer is most definately D. The L2 used to be on the MB but now is built on the CPU itself.
L1, L2 and L3 are now incorporated on the processor chip of the latest processors. I believe the answer is B if the test is based on current available information.
nowadays B. some years ago, it was D.
