Versa Networks VNX301 Exam - Topic 1 Question 5 Discussion

The correct answer is B. The exhibit shows the branch interface summary in Versa Director with a Live Data column. To populate real-time bandwidth graphs for WAN circuits, the administrator must select Live Data for the WAN interfaces that need to be monitored. Versa monitoring documentation states that, from a Director node, you can monitor VOS devices and organizations, and that Director, together with Versa Analytics, can poll VOS devices in real time to understand what is happening on the devices. This real-time information can be displayed to assist with troubleshooting.

Because the question asks for the current bandwidth of each WAN circuit, historical analytics alone is not sufficient. The dashboard must poll live statistics from the selected WAN circuits. In the exhibit, not all WAN interfaces appear to have Live Data selected; therefore, the graph is not populated for all circuits. Refreshing the page does not enable polling and will not solve the missing data condition. Selecting only MPLS would populate only the MPLS circuit, not all WAN circuits. Unselecting and reselecting only the INET circuit would affect only that one interface. Therefore, Live Data must be selected for all WAN circuits whose current bandwidth should be displayed.
