What is one business benefit of Virtual Switching Extension (VSX)?

Question

Options

• AIt helps to optimize ArubaOS switches to connect to servers in a highly virtualized data center
• BIt enables companies to extend services consistently across sites through the use of VPN tunnels
• CIt enables companies to apply consistent policies on wireless users and wired users connected to
• DIt helps to reduce downtime for a network core of ArubaOS switches, while also providing a simple

• A

• B
  6% (2)
• C
  3% (1)
• D
  16% (5)

Explanation

Option A is correct because VSX is an Aruba high-availability architecture that pairs two physical ArubaOS switches into a single logical device - this is especially valuable in virtualized data centers where servers need active-active, dual-homed connections to the network. VSX presents a single logical switch fabric to hypervisors and virtual machines, ensuring consistent, optimized connectivity without the asymmetric routing overhead of traditional spanning-tree designs.

Option B is wrong because extending services across sites via VPN tunnels describes SD-WAN or overlay technologies (like VPLS/L2 VPN), not VSX, which operates at the local switch-pair level.

Option C is wrong because applying consistent policies across wired and wireless users describes a unified policy engine like Aruba ClearPass or role-based access control - not a switching virtualization technology.

Option D is wrong (or at minimum incomplete) because while VSX does improve redundancy and simplify management, the exam is testing its data center virtualization benefit specifically - downtime reduction is a byproduct, not the primary business driver being examined here.

Memory tip: Think "VSX = Virtual Switch for virtualized servers." The "V" connects VSX to the virtualized data center use case - two physical switches become one logical switch that VMs see as a single, always-on fabric.
