Aruba CX 10000 Advanced study guide
Aruba CX 10000 Advanced · Work through your exam, one topic at a time.
The Aruba CX 10000 Advanced credential is aimed at network engineers, data center architects, and security-focused operators who design, deploy, or support the CX 10000 switch series. The platform's distinguishing feature is its embedded AMD Pensando DPU, which delivers line-rate stateful firewall, NAT, encryption, and telemetry services directly in the switch rather than in a separate appliance or hypervisor. The Aruba CX 10000 Advanced study guide has 8 sections and about 2,388 words.
01CX 10000 Architecture and Hardware Platform
The Aruba CX 10000 is a top-of-rack data center switch that pairs a conventional switching ASIC with an embedded AMD Pensando DPU (a programmable packet processor) sitting in the traffic path. Candidates should be able to explain the split of responsibilities: the main ASIC handles high-speed L2/L3 forwarding, buffering, and fabric encapsulation, while the DPU provides stateful services - distributed firewall, NAT, encryption, and telemetry - at line rate, distributed to every leaf rather than hairpinned to a central appliance.
340 words, about 2 min02AOS-CX Fundamentals and Configuration Management
AOS-CX is a Linux-based network OS with a modular, database-driven design. Candidates must be fluent in the operational model: candidate configuration versus running configuration, checkpoint and rollback , configuration profiles, and the REST API/CLI duality.
304 words, about 2 min03Layer 2 and Layer 3 Networking on CX 10000
This domain tests solid data center L2/L3 fundamentals as implemented in AOS-CX. On the L2 side, understand VLANs, access versus trunk ports, native VLAN behavior, spanning tree (MSTP/RPVST interop), loop protection, and why modern data centers favor L3 underlay plus EVPN over large L2 domains.
306 words, about 2 min04Distributed Services and Stateful Firewall (AMD Pensando DPU)
The CX 10000's differentiator is stateful, distributed services enforced on the DPU at each switch. Candidates must understand what "stateful" buys you: connection tracking so return traffic is permitted automatically, plus policy that can match on L3/L4 (and often L7 context) rather than stateless ACL tuples.
302 words, about 2 min05EVPN-VXLAN and Data Center Fabric Integration
EVPN-VXLAN is the fabric model CX 10000 operates within. Candidates should know the roles: VTEPs encapsulate tenant traffic in VXLAN (UDP), while EVPN (BGP address families) distributes MAC/IP reachability and avoids unknown unicast flooding.
292 words, about 1 min06Security Policy, Segmentation, and Micro-segmentation
This domain tests how segmentation is designed and enforced on CX 10000. Candidates must distinguish macro-segmentation (VRFs, VLANs, subnets) from micro-segmentation (fine-grained, workload-to-workload policy).
290 words, about 1 min07Telemetry, Monitoring, and Analytics
CX 10000 emphasizes deep visibility. Candidates should know the telemetry toolkit: streaming telemetry (push-based, model-driven) versus traditional SNMP polling, and why streaming is preferred for high-frequency data center monitoring.
285 words, about 1 min08High Availability, Operations, and Troubleshooting
This domain tests keeping the fabric running and diagnosing failures. Know the HA building blocks: redundant power and fans, VSX active-active pairs, dual-partition boot for safe upgrades, and checkpoint/rollback for configuration recovery.
