Refer to the exhibit.An architect must design an IGP solution for an enterprise customer. The design must support: -Physical link flaps should have minimal impact. -Access routers should converge quickly after a link failure.Which two ISIS solutions should the architect include in the design? (Choose two.)

A. Use BGP to IS-IS redistribution to advertise all Internet routes in the Level 1 area. B. Advertise the IS-IS interface and loopback IP address toward the Internet and data center. C. Reduce SPF and PRC intervals to improve convergence time. D. Configure all access and aggregate routers to establish Level 1 / Level 2 adjacencies across the network. E. Configure access routers to establish a Level 1 adjacency and aggregate routers to establish a Level 1 / Level 2 adjacency.
