The architect should recommend the use of Virtual Switching Framework (VSF) in this network because it simplifies the topology and eliminates the need for spanning tree. VSF is a technology that allows multiple Aruba switches to operate as a single logical device, providing high availability, scalability, and simplified management. By using VSF, the architect can reduce the number of links and devices in the network, and avoid the complexity and inefficiency of spanning tree protocol (STP), which is used to prevent loops in a network. VSF also enables faster convergence and recovery in case of link or device failures, as well as load balancing and link aggregation across the switches.
The other options are not valid reasons for using VSF in this network:
Option A is incorrect because VSF does not enable software-defined network monitoring in conjunction with AirWare. AirWare is a network management platform that provides visibility and control over the entire network, including wired and wireless devices, applications, and users. VSF does not directly affect the functionality of AirWare, nor does it provide any additional features for software-defined network monitoring.
Option B is incorrect because VSF does not transform switches into virtual extensions of the MCs to simplify MST management. MCs are mobility controllers that provide centralized control and configuration for wireless access points and gateways. VSF does not integrate the switches with the MCs, nor does it affect the MST (Multiple Spanning Tree) protocol, which is an enhancement of STP that allows multiple instances of STP to run on different VLANs.
Option C is incorrect because VSF does not enable administrators to manage all 18 switches as a single switch. VSF allows the switches to operate as a single logical device, but they still retain their individual identities and configurations. Administrators can use the VSF commander switch as a single point of management for the VSF members, but they still need to access each switch separately for some tasks, such as firmware updates, backups, and restores.
