What two criteria are used to help select network media? (Choose two.)
- the types of data that need to be prioritized
- the cost of the end devices utilized in the network
- the distance the media can successfully carry a signal
- the number of intermediary devices installed in the network
- the environment where the media is to be installed
What are two functions of intermediary devices on a network? (Choose two.)
