Explanation
{"question_number": 9, "question": "In an SD-WAN architecture, which methods are used to bootstrap a vEdge router?", "correct_answer": "C. ZTP or manual configuration", "explanation": "In Cisco SD-WAN (Viptela architecture), a new vEdge router must authenticate with the controllers (vBond, vSmart, vManage) before it can join the overlay. There are two supported bootstrap methods: (1) ZTP (Zero Touch Provisioning) - the vEdge device contacts the Viptela ZTP server in the cloud using a pre-loaded serial number and certificate, discovers the vBond orchestrator, and automatically onboards. (2) Manual configuration - an administrator directly enters the vBond IP address and organization name on the device. DHCP options and DNS records (A, D) are not standard vEdge bootstrap mechanisms. vManage (B) is the management plane used after onboarding, not the bootstrap method itself, and DNS records alone are not sufficient to complete the bootstrap process.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
