An architect has planned the wireless and wired access layers for a network upgrade. The entire solution must support 9,000 wireless devices and 2,250 wired endpoints.
The campus core must meet these requirements:
✑ no more than 4:1 oversubscription on the links to the data center
✑ switch-level redundancy
✑ near instant failover if one core switch fails
✑ link aggregations between access layer and core
✑ same switch software used across the entire campus
