Which of the following is not a reason that OSPF and EIGRP are more desirable WAN protocols?

a. The amount of memory in the remote routers is usually smaller.
b. Built-in functions to filter out routes.
c. They send periodic updates.
d. All the above are reasons.


c. They send periodic updates.
Explanation: OSPF and EIGRP are more desirable protocols for WAN routing because they send updates only when routing changes occur. The size of the router at the remote site will also play a part in the routing protocols you implement. The amount of memory in the remote routers is usually smaller than in the LAN routers. Therefore, the size of the routing table that can be passed to the remote site might need to be smaller than the routing table at the LAN site. Some routing protocols, such as OSPF, have built-in functions to filter out routes.
