Match the HPE Aruba Networking CX switch feature with the correct product line.

Built-in stateful firewall = D

400Gb port speeds = C

7–12U chassis form factor = A

8U chassis form factor = B

The correct matches are CX 10000 for built-in stateful firewall, CX 9300 for 400Gb port speeds, CX 6400 for the 7–12U chassis form factor, and CX 8400 for the 8U chassis form factor. HPE Aruba Networking documentation describes the CX 10000 Distributed Services Switch as including stateful firewall capabilities through its distributed services architecture, making it the correct match for built-in stateful firewall. The CX 9300 is identified by HPE Aruba Networking as a high-density 100G/400G switch platform, so it matches the 400Gb port-speed feature. The CX 6400 is a modular chassis family available in 5-slot and 10-slot models; HPE QuickSpecs describe these as compact 7 RU and 12 RU chassis models, matching the 7–12U chassis form factor. The CX 8400 is a modular campus core and aggregation switch described by HPE as a compact 8-slot, 8U chassis, which matches the 8U chassis form factor. These four features are product-line differentiators and should not be interchanged.
