What are two benefits of using Cisco NSO? (Choose two.)

A. It abstracts the device adapter and complex device logic from the service logic.

B. It uses load balancing services for better traffic distribution.

C. It easily integrates into northbound systems and APIs.

A user is debugging a problem with model-driven dial-in/out streams with gRPC for a Cisco IOS XR implementation. There is no streaming data and the path is not resolved when the show telemetry model-driven subscription command is issued on the router. What is the cause of the problem?

A. The emsd process is not running.

B. There are polling interval problems.

C. SNMP is not enabled.

D. There is no support for IOS XR 64-bit.

Refer to the exhibit. When YDK is used to interact with Cisco routers, what is the purpose of passing intf_f into the crud_service.read() method?

A. The Interfaces() class acts as a NETCONF filter, which limits the data returned to that of the openconfig:interfaces YANG model.

B. It provides the data types of the openconfig:interfaces model to the router for dynamic configuration of the interfaces.

C. It locks the interfaces from modification by other active NETCONF sessions.

D. It passes default values into the crud_service, which reconfigures all interfaces to their default configurations.

Refer to the exhibit. Which two configuration leaves in this YANG model are optional? (Choose two.)
