Questions 11–15

1. 11application · medium

   A network engineer is testing a new JET application that uses the REST API to configure interfaces on a Junos device. The application is able to connect to the device and authenticate successfully, but when it attempts to make a configuration change, it receives an 'access denied' error. What is the most likely cause of this issue?

   • AThe user account has read-only permissions in the JSD application-level configuration.
   • BThe REST API is not enabled on the device.
   • CThe JSD process is not running on the device.
   • DThe application is using the wrong API endpoint for configuration changes.

   How does JSD interact with other Junos processes to fulfill automation requests?

   • AIt directly modifies the kernel routing table.
   • BIt bypasses other processes and writes directly to the configuration database.
   • CIt uses internal Junos APIs to communicate with processes like mgd and rpd.
   • DIt only communicates with external applications and not with other Junos processes.

   A network engineer is configuring JSD on a Junos device to support a JET application that will use both the REST and gRPC APIs. The engineer has enabled JSD and configured the REST API. However, the gRPC API is not working. The engineer checks the configuration and sees that the 'grpc' statement is missing from the 'junos-extension-service' hierarchy. What is the most likely reason the gRPC API is not working?

   • AThe gRPC API must be explicitly configured under the 'junos-extension-service' hierarchy.
   • BThe gRPC API is not supported on this Junos device model.
   • CThe gRPC API requires a separate license that has not been installed.
   • DThe gRPC API is enabled by default when JSD is enabled.
