Refer to the exhibit. An architect is designing an ISIS solution with these requirements:
- The backbone area will grow to 50 routers in the next 12 months.
- Routers A1 and A2 must avoid suboptimal routing.
- Summarization and route-leaking should be allowed in areas 49.002 and
49.003.

Drag and drop the characteristics from the left onto the correct telemetry mode on the right.
Drag and drop the characteristics from the left onto the correct telemetry mode on the right.
正解：
Explanation:
In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed.
Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription.
All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.

Refer to the exhibit. A network engineer must design a BGP solution based on:
- The route reflector must have one or more direct physical connections to the core routers (R3 and R4).
- The route reflector must have full redundancy and avoid a single
point of failure.
- R2 to R1 link utilization is 90%, and the remaining links are less
than 50% utilized.
Which two solutions must the design include? (Choose two.)
