4.2 You have been tasked with designing an ethernet network. Your client needs to implement a very high-speed network backbone between campus buildings; some of which are around 300 m apart. Multimode fiber-optic cabling has already been installed between buildings. Yourclient has asked that you use the existing cabling. Which ethernet standard meets these guidelines? (Choose two)
a. 1000BaseSX, b. 10BaseFL, c. 1000BaseT, d. 1000BaseCX, e. 10GBaseER, f. 10GBaseSR

5.4 A router is connected to network 192.168.1.0/24 and network 192.168.2.0/24. The router is configured to use RIP and has learned of networks 192.168.3.0/24 and 192.168.4.0/24.
