• BActive/active clustering in gateways and Virtual Switching Extension (VSX) in Aruba CX switches
• CThe customer only needs to be concerned about gateway redundancy, and redundant gateways
• DAir Slice in Aruba APs and Aruba CX switches provide end-to-end protection for these

Explanation

Option C is correct because in an Aruba ESP Unified Infrastructure campus solution, gateway redundancy is the central protection mechanism for real-time and mission-critical application traffic - gateways perform deep packet inspection, QoS enforcement, and application-aware routing, so active/active gateway clustering ensures these flows remain uninterrupted during a failure. Option A is wrong because Aruba Central is a cloud-based management platform, not a site-level active-standby cluster, and it doesn't directly protect application traffic. Option B is a plausible distractor, but it overstates the role of VSX in protecting real-time applications - VSX provides switch-level redundancy, which is a separate benefit and not the key point about real-time/mission-critical application protection. Option D is incorrect because Air Slice is a wireless-specific QoS feature available on Aruba APs, not on Aruba CX switches, making the "end-to-end" claim inaccurate.

Memory tip: Think of the gateway as the "traffic cop" for real-time apps - it's the one enforcing priority rules, so keeping it redundant is the key protection point. If you see "end-to-end" language paired with a feature that doesn't span the full path (like Air Slice on switches), it's a red flag that the option is wrong.
