3 B. allows mobile aggregation C. eliminates TDM interconnects D. permits addition of optical interconnects Correct Answer: D QUESTION 5 True or false: The intelligence of the network must be moved out from the core. A. True, because there are many core devices and keeping them will reduce costs. B. False, because core devices must be the fastest and support the most features. C. True, because core devices must be as fast as possible, even at the expense of features. D. False, because this would violate the basic concepts of IP NGN network structure. Correct Answer: C QUESTION 6 What are three of the key competitive differentiators of the Cisco Prime suite? (Choose three.) A. drag-and-drop troubleshooting B.

A. Local traffic is switched locally, and routed traffic is forwarded to the upstream ASR 9000 Router.

4 B. Local traffic is routed and switched locally. The configuration is done on the upstream ASR 9000 and pushed onto the satellite ASR 9000v. Only traffic leaving satellite device is forwarded over uplinks. C. All traffic is forwarded to the upstream ASR 9000 and no processing is done locally. D. All traffic is forwarded to the upstream ASR 9000, but minimal mandatory local processing is done by the satellite device. Correct Answer: D QUESTION 8 Which three of these platforms support IOS XR? (Choose three.) A. ASR1000 Series B. ASR 9000 Series C. Cisco 7600 Series D. CRS E. Cisco Series F. Cisco Series Correct Answer: BDE QUESTION 9 Which software platform is the foundation of IOS XR? A.

CRS-1 is a one-slot, high-performance core router, while CRS-3 is a three-slot PE router. A. 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. B. CRS-3 is the next generation of the CRS series, designed for 100GE performance. While using the same operating system, the components are not interchangeable due higher demands of the third generation of the CRS.

5 C. CRS-3 is the continuation of the CRS series, extending the number of line cards by a factor of three. D. It is possible to build multishelf systems that are three times larger, with throughput that is also three times larger.
