Aruba Campus Access Architect (HPE7-A11) study guide
Aruba Campus Access Architect (HPE7-A11) · Work through your exam, one topic at a time.
The Aruba Campus Access Architect (HPE7-A11) is a professional-level certification for network engineers who design and validate campus access networks built on Aruba wired and wireless products. It suits senior engineers, pre-sales and solution architects, and consultants who already work hands-on with Aruba switches, access points, and management tooling and want to demonstrate design-level judgement rather than device-level configuration alone. The Aruba Campus Access Architect (HPE7-A11) study guide has 6 sections and about 1,609 words.
01Architecture and Design
Aruba campus design starts from a small set of decisions that cascade through everything else: the number of tiers, whether the design is routed-access or a traditional core/aggregation/access model, how large each Layer 2 domain is, and where the control plane for wireless lives. Aruba's recommended modern pattern is a two-tier collapsed core with Layer 3 access (routed access) using VSX for core redundancy and VSF for access switch stacking.
316 words, about 2 min02Wired and Wireless Campus Access Infrastructure
Understand Aruba's AOS-CX switch families and their roles: CX 6000/6100 for small branch access, CX 6200 for mainstream access, CX 6300 for aggregation and high-density access, CX 6400 modular chassis, and CX 8360/8400 for core and data center. Know the port types (1G, 10G, 25G, 40/100G), PoE classes, and stacking (VSF) capabilities.
272 words, about 1 min03Network Security and Segmentation
Aruba supports multiple segmentation approaches: VLAN-based segmentation (traditional), role-based access via Aruba ClearPass and downloadable user roles, and microsegmentation using AOS-CX and Aruba Central. Understand the difference between VLAN-centric design and role-centric design - the latter decouples policy from topology and is preferred for dynamic environments.
273 words, about 1 min04Network Management, Monitoring, and Automation
Aruba offers Aruba Central (cloud), Aruba Central On-Premises, AirWave (legacy on-prem), and local management via AOS-CX CLI/Web UI. Know which platforms manage which devices: Central manages AOS-CX, AOS-S, Aruba APs, and gateways; AirWave historically managed AOS-S and controllers.
245 words, about 1 min05High Availability, Resilience, and Troubleshooting
Know the HA options at each layer: VSF stacking (single logical switch, redundant members), VSX (two chassis with independent control planes and a sync link), MC-LAG, and gateway clustering. Understand that VSX requires an ISL (inter-switch link) and a keepalive path, and that split-brain prevention depends on the keepalive.
255 words, about 1 min06Integration, Migration, and Operations
Aruba integrates with identity providers (Active Directory, LDAP, SAML), SIEM tools, ITSM platforms, and third-party NAC via ClearPass. Understand API-based integration (REST), syslog forwarding, and how Central connects to external services.
