300-435 Question 135
Single answerAn organization is deploying new branch routers using Cisco Plug and Play (PnP). The network engineer wants to ensure a fully automated provisioning process. During the PnP process, which prerequisite must be met for the devices to communicate with the Cisco DNAC (Digital Network Architecture Center) without manual intervention?
- A
The devices must have a pre-configured static IP address.
- B
The DHCP server must be configured with option 43 to provide the Cisco DNAC server information.
- C
The routers must be manually added to the inventory in Cisco DNAC before the PnP process starts.
- D
The devices must use a factory-default configuration with no pre-loaded scripts.
Show answer and explanation
Correct answer: B
Explanation
For a fully automated Cisco PnP deployment, the devices need to communicate with the Cisco DNAC server. This is achieved through DHCP option 43, which provides the devices with the IP address or hostname of Cisco DNAC during boot. This eliminates the need for static IP configuration or manual inventory addition, ensuring a seamless provisioning process.
- A. Incorrect.
This is incorrect because PnP does not require a pre-configured static IP. Instead, the device obtains an IP through DHCP.
- B. Correct.
This is correct because DHCP option 43 is used to provide the PnP-enabled device with the IP address of the Cisco DNAC or PnP server during the boot process.
- C. Incorrect.
This is incorrect because devices do not need to be manually added to the inventory in Cisco DNAC prior to the PnP process. The process is designed to dynamically register devices.
- D. Incorrect.
This is incorrect because while using factory-default configurations is important, it is not sufficient on its own to establish communication with Cisco DNAC. DHCP option 43 is still required.
