   An automation engineer is developing a script that uses the Junos PyEZ library to execute operational commands and retrieve the output. The script needs to handle devices that may not support the same command syntax. Which approach should the engineer use to ensure the script works across different Junos versions?

   • AUse the 'rpc' method in PyEZ to execute the underlying RPC for the command.
   • BUse the REST API to execute the command and parse the JSON output.
   • CUse the 'cli' method in PyEZ to execute the command and parse the text output.
   • DUse the J-Web interface to execute the command and parse the HTML output.

   A network administrator is using the J-Web interface to monitor the status of interfaces on a Junos device. The administrator notices that the J-Web interface is slow to respond. Which statement correctly describes how J-Web interacts with MGD?

   • AJ-Web sends SNMP requests directly to the forwarding plane to gather interface statistics.
   • BJ-Web uses NETCONF to communicate with MGD, which then processes the requests and returns the data.
   • CJ-Web uses HTTP/HTTPS to communicate with the web server, which then interacts with MGD to process the requests.
   • DJ-Web uses CLI commands to gather information, which are then processed by MGD.

   How does MGD contribute to the separation of management from forwarding in Junos?

   • AIt directly programs the forwarding table to manage traffic
   • BIt runs in the control plane, while forwarding is handled by the Packet Forwarding Engine
   • CIt runs on the same processor as the forwarding engine to reduce latency
   • DIt uses a separate physical processor for each management session
