350-601 Question #483: Real Exam Question with Answer & Explanation

Question

A network engineer needs a solution that simplifies the initial deployment of Cisco Nexus Series Switches. The solution must support these requirements: - zero-touch provisioning - configuration through DHCP options - initial configuration from a central TFTP server - no manual configuration management after the initial installation Which technology supports these goals?

Options

• AAnsible
• BCisco Intersight
• CChef
• DPOAP

Explanation

A network engineer needs a solution for zero-touch provisioning of Cisco Nexus Series Switches, including initial configuration from a central TFTP server via DHCP options, without manual intervention. POAP is the technology designed for these specific automation goals.

Common mistakes.

• A. Ansible is a configuration management tool used for ongoing automation and orchestration, but it typically requires initial network connectivity and configuration to execute playbooks, which is not zero-touch for initial device bring-up.
• B. Cisco Intersight is a cloud-based management platform primarily for Cisco UCS and HyperFlex, and while it offers deployment automation, it's not the primary solution for zero-touch provisioning of Nexus switches using DHCP/TFTP like POAP.
• C. Chef is a configuration management tool, similar to Ansible, that focuses on infrastructure as code and automation, but it does not provide the inherent zero-touch initial provisioning mechanism leveraging DHCP and TFTP as required for new devices.

Concept tested. Cisco Nexus zero-touch provisioning (POAP)
