Q2. In a secure domain router scenario, which two functions are shared amongst all SDR in the system? (Choose two.)
A. configuration
B. protocols
C. routing tables
D. chassis-control
E. switch-fabric
Answer: D,E
Explanation:
Secure domain routers (SDRs) provide a means of partitioning a router into multiple, independent routers. SDRs perform routing functions in the same manner as a physical router but share resources with the rest of the system. For example, the applications, configurations, protocols, and routing tables assigned to an SDR belong to that SDR only, but other functions such as chassis control, switch fabric, and partitioning are shared with the rest of the system.
