An organization finds that most of the outgoing traffic on the network is directed at several Internet
sites viewed by multiple computers simultaneously. Which of the following performance
optimization methods would BEST alleviate network traffic?
A.
Load balancing internal web servers
B.
Redundant network resources
C.
Implement fault tolerance on the WAN
D.
Implement caching engines

bandwidth.
