HP0-Y51 Question #1: Real Exam Question with Answer & Explanation
The correct answer is D. Disable spanning tree on the OpenFlow-enabled switches and configure the redundant links as static link aggregations. See the full explanation below for the reasoning.
Question
Refer to the exhibit. The switches shown in the exhibit use the HP VAN SDN Controller as the OpenFlow controller. They connect to the controller on their out-of-band management (OOBM) ports. But these connections are not shown in the exhibit. The switches also run spanning tree protocol. An SDN application installed on the HP VAN SDN Controller is programmed to discover live ports, find redundant paths, and create loopfree paths for traffic infrastructure shown in the exhibit. However, the application is not able to complete these functions because the switches are reporting some ports as blocked. What should the administrator do to let the application create the loopfree paths?
Options
- ADisable spanning tree on the OpenFlow-enabled switches and do not configure link aggregation.
- BEnable spanning tree on the OpenFlow-enabled switches but set the application as the spanning tree flood parameter controller.
- CEnable spanning tree on the OpenFlow-enabled switches and configure all of the redundant links as egress-only-ports
- DDisable spanning tree on the OpenFlow-enabled switches and configure the redundant links as static link aggregations
