Question 8
Whatis the impact of RSP reload on the switch fabric on the ASR 9000 Series?
- A. None. The switch fabric resides on dedicated fabric cards and the reload of a separate RSP card has no impact.
- B. Interruption of service. The switch fabric resides on the same card as RSP and the reload of the card will cause packet loss.
- C. 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.
- D. None. The switch fabric resides on the same physical card as RSP, but the circuits are independent.
Answer : B
