Question
What are the two impacts of losing vManage connectivity to fabric in the Cisco SD-WAN network? (Choose two.)
Options
- APolicy ceases propagation stops.
- BCreation of templates is impossible.
- CBFD peering between WAN Edge devices are established.
- DStatistics collection stops.
- EIPsec tunnels tear down for WAN Edge devices.
Explanation
Losing vManage connectivity to the SD-WAN fabric impacts the ability to push new policy configurations and halts the collection of network performance statistics.
Common mistakes.
- B. Template creation is a function of the vManage user interface itself; an administrator can still create templates even if vManage loses connectivity to the fabric, although deployment would be impossible.
- C. BFD peering and IPsec tunnel establishment are handled by the vSmart controller (control plane) and WAN Edge devices (data plane); once established, they typically continue to function independently of vManage's connectivity to the fabric.
- E. IPsec tunnels are managed by vSmart and WAN Edge devices, and they typically remain operational as long as the vSmart controller is reachable and functioning, even if vManage loses connectivity to the fabric.
