The correct answer is C. Configure an IP helper address on interface VLAN 10 of the management switch. To enable Zero-Touch Provisioning (POAP) for Cisco Nexus switches managed by DCNM in a new environment, an IP helper address must be configured on the management switch's interface VLAN.
Question
Refer to the exhibit. An engineer must deploy 70 Cisco Nexus 9000 Series Switches in a new environment. The requirement is to use Cisco DCNM as a management tool to deploy, manage and monitor the new switches. In addition. DCNM is configured with a zero-touch POAP feature to facilitate fabric creation. Which action meets these requirements?
Exhibit
Options
- AConfigure SNMP on the new Nexus switches to send SNMP messages to the DCNM server
- BCreate a SPAN session on the management switch to send the traffic from VLAN 10 to Ethernet
- CConfigure an IP helper address on interface VLAN 10 of the management switch
- DCreate common credentials on all of the new Nexus switches

Why each option
To enable Zero-Touch Provisioning (POAP) for Cisco Nexus switches managed by DCNM in a new environment, an IP helper address must be configured on the management switch's interface VLAN.
Configuring SNMP is for monitoring after the switch is provisioned and managed, not for the initial zero-touch deployment via POAP.
Creating a SPAN session is for network traffic analysis and has no role in the initial zero-touch provisioning of switches.
Configuring an IP helper address on interface VLAN 10 of the management switch ensures that DHCP broadcast requests from the new Nexus switches are forwarded to a DHCP server, which is crucial for POAP to obtain IP addresses and discover the DCNM server or TFTP server for initial configuration files.
Creating common credentials on all new Nexus switches is not part of the zero-touch POAP process; POAP aims to configure the switch from scratch without manual intervention, including setting initial credentials.
