You have several sites, each with different administrative units in your company. Which routing protocol should you choose?

A. BGP
B. OSPF
C. RIPv2
D. EGP

B. Although you have different administrative units, all of the administrative units are in the same company. In this situation, it is recommended to use an interior gateway protocol that can segment each administrative unit. OSPF will perform this requirement with the use of area IDs.
