It terminates subscriber access lines. ✘ It provides fast switching capability. ✘ It handles VPN access. ✘ It aggregates subscriber access. ✔

simplifies manageability ✘ allows mobile aggregation ✘ eliminates TDM interconnects ✘ permits addition of optical interconnects ✔

True, because there are many core devices and keeping them will reduce costs. ✘ False, because core devices must be the fastest and support the most features. ✘ True, because core devices must be as fast as possible, even at the expense of features. ✘ False, because this would violate the basic concepts of IP NGN network structure. ✔

Local traffic is switched locally, and routed traffic is forwarded to the upstream ASR 9000 Router. ✘ Local traffic is routed and switched locally. The configuration is done on the upstream ASR 9000 andpushed onto the satellite ASR 9000v. Only traffic leaving satellite device is forwarded over uplinks. ✘ All traffic is forwarded to the upstream ASR 9000 and no processing is done locally. ✘ All traffic is forwarded to the upstream ASR 9000, but minimal mandatory local processing is done by thesatellite device. ✔

CRS-3 is the continuation of the CRS series, fully compatible with all line card components, RPs, and fabric. The only advantage is larger throughput of fabric and line cards. ✘ CRS-3 is the next generation of the CRS series, designed for 100GE performance. While using the sameoperating system, the components are not interchangeable due higher demands of the third generation of the CRS. ✘ CRS-3 is the continuation of the CRS series, extending the number of line cards by a factor of three. ✘ It is possible to build multishelf systems that are three times larger, with throughput that is also three timeslarger. ✔

None. The switch fabric resides on dedicated fabric cards and the reload of a separate RSP card has no impact. ✘ Interruption of service. The switch fabric resides on the same card as RSP and the reload of the card willcause packet loss. ✘ Performance degradation. The switch fabric resides on the same card as RSP and the reload will stop it.However, having a redundant RSP installed means traffic that all traffic will be redirected to another RSP and this will halve the throughput rate, but not cause any disruption. ✘ None. The switch fabric resides on the same physical card as RSP, but the circuits are independent. ✔
