Designing Cisco Network Service Architectures (ARCH) (#164)

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?

QoS is required on the VSL links.
Limited bandwidth is available for VSS convergence.
The design lacks optimal hardware diversity.
The implementation creates a loop.
