Refer to the exhibit.
A customer needs a network upgrade. The customer has these availability requirements for wireless access:
✑ One MC and one core switch can fail with immediate, stateful failover for client connections.
✑ Network upgrades can occur without the requirement of a maintenance window.
The exhibit shows the architecture plan.
Which technologies should the architect recommend?
To meet the customer's requirements for high availability and the ability to perform network upgrades without a maintenance window, the architect should recommend clustering on the Mobility Controllers (MCs) and Virtual Switching Framework (VSF) on the core switches. Clustering on the MCs ensures immediate, stateful failover for client connections when one MC fails. VSF on the core switches provides redundancy and simplifies management, enabling the network to handle failures and upgrades seamlessly. This combination meets both the immediate failover and upgrade requirements efficiently.
