An advantage of centralized routing is:

A) routing does reflect changing network conditions, such as computers that are overloaded by many messages
B) if anything happens to the computer developing the routing table, the routing tables cannot be changed until that computer is fixed, or until a new computer is selected to perform the function
C) routing decisions are simple
D) the routing tables are stored at all computers in the network
E) it requires more processing by each computer or router in the network than dynamic routing

One drawback to dynamic routing is:

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.
