IBM 287 Sample test question

hi all
For this question from IBM 287 Sample Exam, which answer is correct ?
Is it A or C ? Both seem to be probable.
A web application is experiencing very large volumes of traffic and profiling has shown that the amount of session data managed by the server is becoming too large for it to handle. Which of the following is the BEST way to solve the problem?
A. Use the HttpSession to store only key values which can be used to access data in a third-tier system.
B. Configure the application server to use URL rewriting instead of Cookies to manage the session ID.
C. Disable HttpSession serialization to prevent automatic storage of HttpSession objects during periods of heavy load.
D. Use HTML hidden fields to manage client-specific application data instead of HttpSessions.
Thanks
Vipin

Hello Vipin,
Does C really seem reasonable to you?

hi Howard
I was thinking of session state replication / migration. Won't it add to traffic ? Are you saying that A is the correct answer ? Could you please elaborate ?
Thanks a lot

Hello again Vipin,
I will answer your question with another question. Let us presume for a moment that C is correct (making A incorrect). How would you accomplish C?

Okay Vipin,
You've been a very good sport. In my opinion A is the correct answer. B and D are clearly wrong, and C just does not make sense to me. The writers of the test have done a good job of confusing the person who may not know the best answer, and who might be tempted to guess.
