Given: Before performing a site survey for a hospital, the network manager notifies you that there is a connection-oriented, real-time medical application used across the hospital’s wired network.
This application will also be used on the WLAN once it is installed. Because the application is real-time, it is sensitive to service disruptions and latency. For this reason, it is particularly important to locate sources of RF interference, blockage, and dead spots.
What can put the application at risk of time-outs? Choose 2

A.
High patient density in a given area

B.
Long hallways

C.
Elevator shafts

D.
Metal mesh glass

E.
Intercom system
