The cells from each session will follow different routes due to load balancing. ✘ The WAN Manager will dynamically route each cell over the current best path. ✘ The cells for one session will typically route dynamically over different paths following the path with leastcurrent delay. ✘ The cells for one session will randomly follow different paths. ✔ The cells for one session will typically follow the same path in the network. ✔

0% ✘ One sixth (about 17%) ✘ 0.00% ✘ None of the above ✔ None ✔

The VPI/VCI is mapped to the FR DLCI. ✘ The IWF supports the mode of mapping FR DE to the CLP of each ATM cell belonging to that frame. ✘ The IWF supports the mode of mapping FR FECN to the EFCI of each ATM cell belonging to that frame. ✘ The FR Command/Response fields are mapped to the corresponding ATM PTI fields. ✔ On the egress towards the FR CPE, the DE is set ONLY if all cells belonging to that frame are set. ✔

By the Network Management Station By the switch to inform the ATM network that this cell is not conforming and MUST be discarded. By the switch to inform the end user that it is sending too much data. By the switch to inform the ATM network that this cell is not conforming and MAY be discarded. By the CPE to tell the switch that this cell has lower priority.
