A customer with stacked switches needs PoE+ ports featured with near-zero downtime, continuous packet forwarding,...

The correct answer is D. CX 6300M in VSF. The requirement includes stacked switches, PoE+ ports, near-zero downtime, continuous packet forwarding, and highly available hardware. HPE Aruba Networking CX 6300M switches support PoE models and are part of the CX 6300 stackable switch family. HPE’s CX 6300 QuickSpecs describe high availability by design using VSF in-service software upgrades, with no downtime or restart when upgrading within the same major release, provided there is at least a two-member VSF stack. The CX 6300 family also supports modular and fixed models in a single stack and includes PoE-capable models. Option A is incorrect because the CX 8100 uses VSX rather than VSF stacking and is not the appropriate PoE+ access stack answer. Option B is less correct because the CX 6200F is stackable with VSF but does not provide the same high-availability feature set as CX 6300M. Option C is incorrect because the CX 8320 is a VSX-capable data center/core platform, not the best PoE+ stacked access solution.
