Question
A company with a small network team purchases 10 Cisco Nexus 9000 Series Switches for a network refresh. Some elements of the existing network infrastructure will be retained including DHCP and DNS servers. The company wants the network team to use PowerOn Auto Provisioning (POAP) to configure the switches, but the team only has experience with manual configuration.
Which two additional network infrastructure components must be configured to use POAP? (Choose two.)
A. NETBOOT host discovery
B. GIT server
C. SCP file repository
D. TFTP script server
E. SNMP trap receiver
Answer
To use PowerOn Auto Provisioning (POAP) for automatically configuring Cisco Nexus 9000 series switches, the two additional network infrastructure components that must be configured are:
C. SCP file repository
D. TFTP script server
Explanation
POAP allows a Cisco Nexus switch to be automatically configured when it is powered on and connected to the network. For POAP to work, two key infrastructure elements are required:
- An SCP file repository to store the configuration script and other files the switch needs to download. The switch uses SCP (Secure Copy Protocol) to securely transfer these files.
- A TFTP server to initially serve the configuration script to the switch. TFTP (Trivial File Transfer Protocol) is used to provide the switch with the location of the script in the SCP repository.
When a Nexus switch powers on, it obtains an IP address via DHCP. It then contacts the TFTP server to download a configuration script. This script contains instructions pointing the switch to the SCP server to download its full configuration files and software images.
So in summary, configuring a TFTP server to provide the initial script and an SCP repository to store the full configuration is essential for enabling POAP automated provisioning of Cisco Nexus 9000 switches. The other options – NETBOOT host discovery, GIT server, and SNMP trap receiver – are not directly involved in the POAP process.
