You have configured the network in the following exhibit. Switch A is performing routing functionality via an SVI. You can ping between Computer A and Computer C but cannot ping Computer F. However, Computer F can ping Computers D and E. What is wrong?

A. The VLANs require VTP to be configured.
B. The interfaces are administratively shut down by default and need to be enabled via a no shutdown.
C. Switch B needs to provide routing as well via the SVI.
D. The link between Switch A and Switch B needs to be a trunk.

D. Only one switch in the network needs to provide routing functionality. Since Computers A and C can ping each other, the SVI is configured properly for routing. The most probable cause is that a trunk does not exist between the switches.
