Your system environment is as follows: You have noticed that the traffic on A-eth0 has doubled, as has A-eth1. Strangely, C is using 100% of the CPU time. B has higher than usual loading of apache, but has a CPU running at 80% idle. What could be the problem?
A.The cgi programs on B have saturated Oracle on C with requests.
B.The network on A is too slow to cope with the traffic.
C.The network linking A,B, and C needs to be upgraded.
D.Apache on A is simply twice as popular as before.
E.B and C need to be moved to different physical networks.
Correct Answer This is certainly a possibility.

Incorrect Answer As the CPU load has reached 100%, more network resources probably will not help.
Incorrect Answer This is reasonable, but does not explain what is happening with B and C.
Incorrect Answer There is no evidence to support this.
