The volume of traffic on each subnet C.) The number of subnets on the network D.) The location of the default gateway E.) The number of host IDs on each subnet  1

Uses a point-to-point connection from the transmitter of the transmitting station to the receiver of the receiving station D.) Data transmission in only one direction  2
What are four benefits that can result from applying ISDN networking? (Choose four) A. Full time connectivity across the ISDN is spoofed by Cisco IOS routers using dial on demand routing (DDR) B. Small Once and Home Once sites can be economically supported with ISDN Basic Rate Interface (BRI) servkps C. ISDN replaces Signaling System 7 (SS7) in the Public Switched Telephone Network (PSTIC) backbone D. ISDN can be used as a backup service for a leased line connection between the remote and central chaps E. Modem racking and cabling can be eliminated by integration of digital modem cards on Cisco IOS Network Acess Servers (NAS)  2
