300-420 Question #174: Real Exam Question with Answer & Explanation

Question

Drag and Drop Question Drag and drop the elements from the left onto the functions they perform in the Cisco SD-WAN architecture on the right. Answer:

Explanation

This question assesses the test-taker's knowledge of the core components and their specific functions within the Cisco SD-WAN architecture, requiring correct matching of each component to its role.

Approach. The correct interaction involves dragging each Cisco SD-WAN component to its associated function description:

1. Drag 'vManage' to the box next to 'provides a GUI interface to monitor, configure, and maintain the SD-WAN devices'. vManage is the centralized management system for the entire SD-WAN fabric, offering a graphical interface for all operational aspects.
2. Drag 'vSmart controller' to the box next to 'responsible for the control plane'. The vSmart controller is the centralized control plane element that distributes routing information, policy, and security policies to the WAN Edge devices.
3. Drag 'vBond orchestrator' to the box next to 'performs the initial authentication of WAN Edge devices'. The vBond orchestrator is the initial point of contact for all SD-WAN devices (vManage, vSmart, WAN Edge devices) and performs the vital role of authentication, authorization, and orchestration to establish secure connections within the fabric.

Common mistakes.

• common_mistake. A common mistake is confusing the distinct roles of vBond and vSmart, or misattributing vManage's comprehensive management role. For example, incorrectly dragging 'vBond orchestrator' to 'responsible for the control plane' would be wrong because vBond handles initial authentication and orchestration, while vSmart is specifically the control plane. Similarly, assigning the GUI interface function to vSmart or vBond is incorrect, as vManage exclusively provides the centralized management GUI. Misunderstanding that vBond is the first point of contact for authentication and initial orchestration, separate from the ongoing control plane (vSmart), leads to errors.

Concept tested. The core concept being tested is the understanding of the Cisco SD-WAN architecture, specifically the roles and responsibilities of its foundational components: vManage (management plane), vSmart controller (control plane), and vBond orchestrator (orchestration/authentication plane).
