Question 1

One drawback to dynamic routing is:

Accepted Answer

A) Routing usually does not reflect changing network conditions, such as computers that are overloaded by many messages 
B) It cannot be used with non-government networks 
C) The transmission of status information "wastes" network capacity that could be used to send user messages 
D) It is the job of the network manager, not the computers or devices themselves, to maintain the routing table. 
E) It requires less processing by each computer than static routing.
