A network automation engineer needs to delete a specific static route from a Junos device using gNMI. The engineer knows the exact path of the route in the Junos YANG model. Which gNMI RPC and operation should be used?

Set RPC with an update operation on the static route path

Subscribe RPC with a path to the static route

Set RPC with a delete operation on the static route path

Get RPC with a path to the static route

A gNMI client is receiving 'Permission denied' errors when attempting to subscribe to telemetry data on a Junos device. The client credentials are valid and the gNMI service is enabled. What is the most likely cause of this error?

The gNMI service is listening on an incorrect port

The gNMI service is not enabled in the configuration

The client is using the wrong encoding format

The client's login class does not have permission to access the requested data path

In gNMI, what does a path represent?

A hierarchical reference to a specific data node in the YANG data model.

The authentication method used for the gNMI session.

The physical location of the device in the network.

The IP address and port of the gNMI collector.

A developer needs to retrieve the operational state of the OSPF neighbors on a Junos device using gNMI. The developer knows the Junos YANG module for OSPF. Which gNMI path should be used in the GetRequest?

/network-instances/network-instance/protocols/protocol/ospf/neighbors/neighbor/state

gRPC/gNMI for Junos Telemetry JN0-423 Practice Questions (Page 5)

Part of the gRPC domain, which makes up ~29% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~10–17 in this domain), expect 2–3 from this objective — we provide 30 practice questions to prepare you well beyond it.
