Is this a way that Virtual Switching Extension (VSX) differs from Virtual Switching Framework (VSF)?

VSX is not recommended for the access layer of data centers and campuses while VSF is recommended for the core. VSX and VSF are both high availability solutions that provide redundancy and load balancing across a pair of switches1. However, VSX is recommended for the core and aggregation layers of data centers and campuses, while VSF is recommended for the access layer of campuses1. The statement is false because it reverses the recommended roles of VSX and VSF.
