HPE Aruba Networking Certified Professional - Switching (HPE7-A08)

Teams running Aruba switching across campuses, branches, or data centers often rely on one or two people who understand OSPF, BGP, and Layer 2 design well. When those people are unavailable, outages last longer and contractor costs rise. This course spreads that knowledge across the team.

Role fit: This course suits IT Practitioners and Team Leads with at least two years of networking experience. Staff who are new to Aruba should start with the HPE Aruba Networking Certified Associate (HPE6-A86) course.

Time investment: Plan for about 26 hours per learner across 30 skills of roughly 50 minutes each. That works out to 6–8 weeks at a few hours per week.

Risk and security relevance: The course covers ACLs, 802.1X, secure network access, and STP protections against rogue switches that try to take over the topology. These topics support access-control and segmentation reviews.

Change-management notes:

• Demos use a virtualized lab. The instructor notes that some data-plane behavior, such as private VLANs, may not work in emulation even though the commands are correct. Validate those changes on real hardware before production rollout.
• The REST API and NAE skills introduce automation and monitoring. Coordinate with change-control owners before agents or scripts touch live switches.

How CBT Nuggets supports it: Each skill ends with a validation challenge, such as troubleshooting OSPF configuration issues or identifying the right Aruba product for identity-based policy enforcement. Use Playlists to sequence routing, security, and automation tracks by role, and Team Reporting to track progress toward HPE Aruba Networking Certified Professional - Switching (HPE7-A08).

IT teams use this training to resolve the switching and routing problems that cause outages and slow down change work across Aruba campus and branch networks. The course uses validation challenges built on realistic scenarios. In one, your team manages a campus of Aruba switches where high-speed links sit unused across many VLANs. In another, they must stop a rogue switch from taking over the spanning tree topology. In a third, they find out why OSPF neighbors with mismatched hello timers never form an adjacency.

• Faster root-cause isolation: Team Leads can expect engineers to trace a failed ping back to its real cause, such as a native VLAN mismatch on a trunk link, instead of chasing a Layer 3 problem that isn't there.
• More resilient routing at scale: Engineers work with multi-area OSPF, OSPF neighbor formation, OSPF path selection, and route reflection for iBGP topologies. This helps keep routing behavior predictable as campus and branch networks grow.
• Automation that replaces manual checks: Instead of signing in to hundreds of switches over SSH to confirm AOS-CX versions, your team learns to query devices through the Aruba REST API.
• Proactive monitoring and access control: Practitioners set up Aruba NAE agents to watch OSPF, link flapping, and hardware health. They also tighten security with reusable ACL object groups and 802.1X. Issues surface sooner, which supports audit readiness.

Knowledge

• How private VLANs use primary and secondary VLANs to segment devices inside a single broadcast domain
• How STP and Layer 2 optimization keep switched topologies stable, make use of high-speed links, and protect the root bridge from rogue switches
• How OSPF works in single-area and multi-area designs, including DR/BDR election, LSA types, stub areas, filtering, and summarization
• How BGP path selection works across iBGP and eBGP in enterprise routing designs
• How VRFs, multicast, ACL object groups, virtual switching, 802.1X, QoS, and PBR fit into an enterprise Aruba design
• How the AOS-CX REST API and Aruba Network Analytics Engine (NAE) support automation and proactive monitoring workflows

Ability

• Configure OSPF adjacencies on Aruba CX switches from the CLI and find mismatched parameters, such as hello timers, that block peering
• Apply BGP path selection and route filtering concepts to support resilient routing designs
• Build reusable, easy-to-change ACLs with object groups, and secure network access with 802.1X
• Explain how the AOS-CX REST API can support switch automation and operational checks
• Identify built-in and HPE-approved NAE agents that can help monitor network issues and support root-cause analysis
• Troubleshoot connectivity in layers, for example by tracing a failed ping that looks like a Layer 3 fault back to a native VLAN mismatch on a trunk
