An engineer must design a Cisco VSS-based configuration within a customer campus network. The two VSS switches are provisioned for the campus distribution layer and each one has a single supervisor and multiple 10 gigabit line cards.
Which option is the primary reason to avoid plugging both VSL links into the supervisor ports?
A . The implementation creates a loop
B . The design lacks optimal hardware diversity
C . Limited bandwidth is available for VSS convergence
D . QoS is required on the VSL links
Answer: B
Explanation:
The best-practice recommendation for VSL link resiliency is to bundle two 10-Gbps ports from different sources. Doing this might require having one port from the supervisor and other from a Cisco 6708 line card.
When configuring the VSL, note the following guidelines and restrictions:
For line redundancy, we recommend configuring at least two ports per switch for the VSL. For module redundancy, the two ports can be on different switching modules in each chassis.
