What is the benefit of configuring VSX in HPE Aruba Networking Fabric Composer?

Question

Options

• AProvides VLAN isolation
• BEnables redundancy and high availability
• CIncreases bandwidth by using subnetting
• DAllows device virtualization

• A
  8% (2)
• B
  88% (21)
• C
  4% (1)

Explanation

VSX (Virtual Switching Extension) in HPE Aruba Networking Fabric Composer provides redundancy and high availability by pairing two physical switches into a single logical unit - so if one switch fails, the other continues forwarding traffic without interruption, eliminating single points of failure.

Why the distractors are wrong:

• A (VLAN isolation): VLAN isolation is a standard Layer 2 feature unrelated to VSX; VLANs exist independently of whether VSX is configured.
• C (bandwidth via subnetting): Subnetting is an IP addressing concept, not a function of VSX; VSX may enable link aggregation across peers but does so through redundancy, not subnetting.
• D (device virtualization): VSX creates a logical pairing, not true device virtualization (that would describe technologies like HPE's VSF or VMware's vSwitches).

Memory tip: Think of VSX as a "shadow switch" - your primary switch always has a shadow ready to take over instantly, keeping the network alive. VSX = Virtually eXtra resilience.
