4.單項(xiàng)選擇題A medium-sized company has a Class C IP address. It has two Cisco routers and one non-Cisco router. All three routers are using RIP version 1. The company network is using the block of 198.133.219.0/24. The company has decided it would be a good idea to split the network into three smaller subnets and create the option of conserving addresses with VLSM. What is the best course of action if the company wants to have 40 hosts in each of the three subnets?（）

A.Convert all the routers to EIGRP and use 198.133.219.32/27, 198.133.219.64/27, and 198.133.219.92/27 as the new subnetworks.
B.Maintain the use of RIP version 1 and use 198.133.219.32/27, 198.133.219.64/27, and 133.219.92/27 as the new subnetworks.
C.Convert all the routers to EIGRP and use 198.133.219.64/26, 198.133.219.128/26, and 133.219.192/26 as the new subnetworks.
D.Convert all the routers to RIP version 2 and use 198.133.219.64/26, 198.133.219.128/26, and 133.219.192/26 as the new subnetworks.
E.Convert all the routers to OSPF and use 198.133.219.16/28, 198.133.219.32/28, and 198.133.219.48/28 as the new subnetworks.
F.Convert all the routers to static routes and use 198.133.219.16/28, 198.133.219.32/28, and
