HPE6-A90 vs HPE6-A85: Which HPE Aruba Networking Certification Should You Choose?

HPE6-A90 and HPE6-A85 are two HPE Aruba Networking exams designed around different aspects of enterprise networking. The HPE6-A90 HPE Networking Central Exam focuses on centralized wired network management, monitoring, and optimization, while the HPE6-A85 HPE Network Campus Access Associate Exam covers foundational wired and wireless campus networking concepts. Understanding their differences can help candidates choose the exam that best matches their experience and career goals.

HPE6-A90 vs HPE6-A85: Key Differences

The most important distinction is that HPE6-A90 concentrates on centralized network management, while HPE6-A85 establishes broader campus networking fundamentals. They are related through the HPE Aruba Networking ecosystem, but they are not simply two versions of the same exam.

What Do HPE6-A90 and HPE6-A85 Cover?

HPE6-A90: HPE Networking Central

HPE6-A90 validates knowledge of managing and monitoring wired networks through HPE Aruba Networking Central. Candidates should understand the platform's management capabilities, network visibility, configuration workflows, and troubleshooting processes.

What Should You Study for HPE6-A90?

Candidates should organize their preparation around the following practical skill areas:

● Central platform fundamentals: Understand the purpose of Central, its management capabilities, and how it supports network administration.

● Wired network management: Learn how to configure and manage supported wired infrastructure through Central.

● Monitoring and visibility: Understand how to review device status, network health, events, and relevant monitoring information.

● Troubleshooting and optimization: Develop a systematic approach to identifying connectivity problems, interpreting operational information, and improving network performance.

● AOS-10 fundamentals: Become familiar with the architectural concepts relevant to managing Aruba networking environments through Central.

These are useful study areas, not a substitute for the current official exam objectives. Candidates should use HPE's published training materials and exam guide to establish the final scope of their preparation.

HPE6-A85: HPE Network Campus Access Associate

HPE6-A85 focuses on the networking principles and technologies used in enterprise campus environments. Candidates should understand how wired and wireless components work together to provide secure and reliable connectivity.

What Should You Study for HPE6-A85?

The published exam objectives identify several important knowledge areas:

● Network stack and connectivity: Understand the OSI model, TCP/IP, and basic networking architectures.

● Switching and routing: Review Layer 2 and Layer 3 technologies, campus architecture, and basic routing topologies.

● Wireless LAN: Understand fundamental radio-frequency characteristics, wireless functions, and access point configuration concepts.

● Network resiliency: Learn about redundancy, fault tolerance, and infrastructure device management.

● Security and authentication: Review fundamental security concepts, AAA, and the integration of wireless networks with authentication services.

● Management and monitoring: Understand common network monitoring tools, UXI test results, and the use of Central to monitor network health.

● Troubleshooting and performance: Apply basic troubleshooting methodologies and understand quality of service (QoS).

Which Exam Should You Take First?

Your choice should depend on your current knowledge and the skills you want to develop.

● Choose HPE6-A85 if you want to build a broad foundation in campus networking, particularly switching, routing, WLAN, authentication, and troubleshooting.

● Choose HPE6-A90 if you already understand networking fundamentals and want to specialize in managing wired infrastructure through HPE Aruba Networking Central.

HPE6-A85 is not identified as a mandatory prerequisite for HPE6-A90 in the published exam information. However, candidates should verify the latest certification requirements before registering. The two exams have complementary objectives rather than representing successive versions of the same exam.

The right choice depends on your existing networking knowledge and professional goals. Neither exam is automatically the best starting point for every candidate.

How to Prepare for HPE6-A90 and HPE6-A85

Follow these practical steps to make your preparation more focused:

1. Review official exam objectives. Use HPE's current exam guides to identify the required topics and prioritize your study time.

2. Combine theory with hands-on practice. Review switching, routing, and wireless concepts for HPE6-A85, or practice Central-based management and monitoring workflows for HPE6-A90.

3. Use practice questions to identify gaps. Review explanations carefully and revisit concepts you find difficult instead of relying on memorization alone.

4. Confirm exam details before booking. Check the latest exam format, delivery languages, passing score, and certification requirements on HPE's official website.
