300-435 Question 130
Select 4You are tasked with automating the deployment of a large number of Cisco Enterprise devices in a data center. To streamline the process, you decide to use iPXE for network booting. Which of the following steps are essential for configuring iPXE to enable the devices to boot and retrieve their configuration files from a central server?
- A
Configure a DHCP server to provide boot file and TFTP server information
- B
Enable PXE boot in the BIOS/firmware of the devices
- C
Set up an iPXE script to define the boot process and configuration file location
- D
Install a dedicated iPXE client on all devices before booting
- E
Use the HTTP protocol in the iPXE script to fetch the configuration file from the central server
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To automate the deployment of Cisco Enterprise devices using iPXE, it is necessary to properly configure the DHCP server, enable PXE booting on the devices, and create an iPXE script that defines the boot process. Using HTTP for file retrieval is recommended due to its efficiency. Installing a dedicated iPXE client is not required, as iPXE operates directly through the firmware or PXE boot process.
- A. Correct.
Correct. A DHCP server is required to provide the devices with the initial boot information, such as the location of the iPXE boot file and TFTP server details.
- B. Correct.
Correct. PXE boot must be enabled in the device's BIOS/firmware to allow network booting using iPXE.
- C. Correct.
Correct. An iPXE script is essential for defining the boot process, specifying how the device retrieves its operating system or configuration file.
- D. Incorrect.
Incorrect. iPXE is a network boot firmware and does not require a dedicated client installation on devices. It works directly with the device's firmware or PXE boot process.
- E. Correct.
Correct. HTTP is commonly used in iPXE scripts as it provides a more efficient and faster method for retrieving files compared to protocols like TFTP.
