VMware SD-WAN by VeloCloud Specialist — Question 11

A customer's network is congested with no degradation of application performance VMWare SD-WAN implements schedulers that control QoS of outbound traffic from the VeloCloud Edge.
Which option describes how this mechanism will work?

Answer options

• A. The Link Steering Policy will prevent packet loss by shaping transmit rates to match the local link bandwidth.
• B. The Dynamic Bandwidth Measurement prevents packet loss by shaping transmit rates to match the local link bandwidth as well as the bandwidth of individual remote peers.
• C. The Network Scheduler implements the QoS hierarchy and is the primary scheduler that influences how bandwidth is shared between edge peers, segments traffic classes, and flows.
• D. The WAN Link Scheduler implements the QoS hierarchy and is the primary scheduler that influences how bandwidth is shared between edge peers, segments traffic classes, and flows.

Correct answer: D

Explanation

The correct answer is D because the WAN Link Scheduler is specifically designed to manage bandwidth sharing and traffic segmentation in VMWare SD-WAN. Option A focuses only on local bandwidth, which is insufficient for comprehensive QoS management. Option B introduces dynamic bandwidth measurement but is not the primary scheduler, while option C incorrectly identifies the Network Scheduler as the main entity responsible for these functions.
