300-435 Question 137
Select 3A network engineer is deploying new branch routers using Cisco's Plug and Play (PnP) solution. The engineer wants to ensure that the branch devices automatically contact the PnP server and download their configurations without manual intervention. Which of the following methods can be used for a PnP-enabled device to discover the PnP server?
- A
DHCP Option 43
- B
DNS Service Discovery
- C
Manual configuration of the PnP agent on the device
- D
TFTP server configuration
- E
Cisco Smart Licensing
Show answer and explanation
Correct answers: A, B, C
Explanation
PnP-enabled devices can use multiple methods to discover the PnP server, including DHCP Option 43, DNS Service Discovery, or manual configuration of the PnP agent. These methods ensure flexibility in different network environments. However, TFTP server configuration and Cisco Smart Licensing are unrelated to the PnP server discovery process.
- A. Correct.
DHCP Option 43 is a valid method for PnP-enabled devices to discover the PnP server by providing the server's IP address in the DHCP response.
- B. Correct.
DNS Service Discovery is a supported method where the device queries a specific DNS hostname to locate the PnP server.
- C. Correct.
Manual configuration of the PnP agent is a valid method to specify the PnP server explicitly on the device when automatic discovery methods are unavailable.
- D. Incorrect.
TFTP server configuration is not a supported method for PnP server discovery. TFTP is primarily used for file transfer, not for PnP server discovery.
- E. Incorrect.
Cisco Smart Licensing is unrelated to PnP server discovery and is used for license management.
