300-435 Question 134
Select 3An organization is deploying new branch routers and wants to use Cisco's Plug and Play (PnP) functionality to simplify the process. The branch routers need to automatically contact the Cisco DNA Center PnP server for configuration. Which method can be used to ensure the routers can discover and connect to the PnP server?
- A
Use DHCP option 43 to provide the PnP server address to the routers
- B
Manually pre-configure the PnP server address on each router via the command-line interface
- C
Use DNS to create a hostname of pnpserver.
that resolves to the PnP server's IP address - D
Enable Cisco Smart Licensing on the routers to automatically discover the PnP server
- E
Use a USB drive containing a configuration file with the PnP server details
Show answer and explanation
Correct answers: A, C, E
Explanation
Cisco's Plug and Play (PnP) functionality supports multiple discovery methods to simplify device onboarding. DHCP option 43 and DNS are automated methods that help devices discover the PnP server without manual intervention. Alternatively, a USB drive with the necessary configuration can be used in scenarios where network-based discovery is not feasible. Manual configuration and Smart Licensing are not designed for automated PnP server discovery.
- A. Correct.
Correct: DHCP option 43 is commonly used to provide the PnP server address to devices during the initial boot process, enabling them to contact the server automatically.
- B. Incorrect.
Incorrect: While this is a valid method to configure the PnP server address, it is not automated and defeats the purpose of simplifying deployment using PnP.
- C. Correct.
Correct: DNS can be used to create a specific hostname (e.g., pnpserver.
) that devices can resolve to discover the PnP server automatically. - D. Incorrect.
Incorrect: Cisco Smart Licensing is unrelated to the PnP discovery process. It is used for license management, not device onboarding.
- E. Correct.
Correct: A USB drive with a pre-configured file containing the PnP server details is another valid method for devices to discover and connect to the server.
