From a network management perspective, a Virtual Chassis consisting of five physical switches will appear as how many devices? Section: (none) Explanation Explanation/Reference: A customer asks you if they should implement nonstop active routing (NSR) in some cases to replace graceful restart in their data center. In this scenario, which two statements are true? (Choose two.)
A. NSR saves routing protocol information by running the routing protocol process (rpd) on the backup Routing Engine
B. NSR is self-contained and does not rely on helper routers (or switches) to assist the routing platform in restoring routing protocol information
C. NSR accounts for large and small traffic flows to ensure coherent forwarding path selection during failover
D. NSR delivers TCP/UDP stream status reducing control plane stress for other networking devices through concatenated announcements from the routing protocol process (rpd)
