HP Aruba Certified Campus Access Architect HPE7-A03 Exam Questions
Question 1
Which is true with regard to device capabilities?
Answer : B
Aruba's recommendation for device density in a generic office environment is based on achieving optimal performance and user experience. The suggestion to support 30-50 devices per radio takes into account the typical bandwidth requirements, application usage, and performance expectations in an office setting. This range is designed to ensure that the wireless network can adequately support the number of devices without significant degradation in service quality. It balances the need for connectivity with the practical limits of wireless technology, ensuring that each device maintains a reliable connection and adequate throughput. This recommendation is part of Aruba's best practices for network design and deployment, aimed at providing efficient and effective wireless coverage in office environments.
Question 2
The clients existing network is experiencing trouble with voice occasionally dropping out on phone calls between office locations, it Is determined that no packet loss is occurring and QOS is likely the cause. With what phenomenon Is the client currently experiencing issues?
A)
B)
C)
Answer : B
The client is experiencing issues with Jitter, as depicted in Option B. Jitter refers to the variation in time between packets arriving, caused by network congestion, timing drift, or route changes. In voice communications, jitter can manifest as the occasional dropping out of voice on phone calls because the variable delay can affect the steady stream of voice packets needed for a clear conversation. Even when there is no packet loss, high levels of jitter can significantly impact the quality of Voice over IP (VoIP) calls. Quality of Service (QoS) settings are essential in managing jitter, as they can prioritize voice traffic over other types of data, ensuring that voice packets are delivered consistently and in the correct order to minimize delays and prevent call quality degradation. Aruba Campus Access solutions would typically include QoS features to manage and mitigate jitter on the network.
Question 3
A customer wants to have the ability to show network usage. Which product would allow them to have this visibility?
Answer : B
Comprehensive and Detailed Explanation From Exact Extract:
Aruba Central:
Aruba Central is the cloud-native management and monitoring platform within the Aruba ESP architecture. It provides:
Network usage visibility: dashboards and reports on client, application, and device traffic across wired, wireless, and WAN.
Application visibility and deep packet inspection (DPI): showing how much bandwidth is consumed by each app or category.
Historical and real-time analytics: enabling IT to monitor utilization trends and demonstrate network usage to stakeholders.
Why not the other options?
UXI (User Experience Insight): Provides end-user experience monitoring by using sensor devices to simulate client behavior (e.g., connectivity tests, SaaS performance), but it does not give full network usage visibility in terms of traffic volume or bandwidth utilization.
ArubaOS 8.x: This is the operating system for Aruba mobility controllers and APs, enabling advanced WLAN features, but not a dedicated platform for traffic visibility dashboards or long-term usage reporting.
ClearPass: Provides policy-based access control and security (authentication, authorization, accounting, device profiling), but it is not designed to show network traffic usage or utilization statistics.
Aruba Design Guidance Alignment:
According to Aruba's Campus Access Design Guides and Aruba Central documentation, the correct tool for showing and reporting network usage visibility is Aruba Central, which integrates AI Insights, traffic monitoring, and reporting capabilities as part of the ESP cloud platform.
Final Justification:
Option B is correct because only HPE Aruba Networking Central provides the ability to monitor and display network usage visibility in a centralized, graphical, and reportable way.
Reference Extracts (Aruba Official Study & Design Guides):
Aruba ESP Campus Design Guide: Aruba Central as the management and visibility layer.
Aruba Central Technical Overview: built-in dashboards for bandwidth utilization, client traffic, and application visibility.
Question 4
A large multinational financial institution has contracted you to design a new full-stack wired and wireless network for their new 6-story regional office building. The bottom two floors of this facility will be retail space for a large banking branch. The upper floors will be carpeted office space for corporate users, each floor being approximately 100.000 sq ft (9290 sqm). Data centers are all off site and will be out of scope for this project. The customer is underserved by its existing L2-based network infrastructure and would like to take advantage of modern best practices in the new design. The network should be fully resilient and fault-tolerant, with dynamic segmentation at the edge.
The retail space will include public guest Wi-Fi access. Retail associates will have corporate tablets for customer service, and there will be a mix of wired and wireless devices throughout the retail floors. The corporate users will primarily use wireless for connectivity, but several wired clients, printers, and hard VoIP phones will be in use.
The customer is also planning on renovating the corporate office space in order to take advantage of "smart office' technology. These improvements will drive blue-dot wayfinding. presence analytics, and other location-based services
The client is looking to utilize lower-cost Aruba OS-CX switches in their wiring closets. They calculate that each closet will need a stack or qty 6 POE (AT) and qty 0 Gigabit Ethernet switches stacked with low-cost OACs.
Which series switch should you recommend?
Answer : C
The Aruba CX 6300F series is a suitable recommendation for the described scenario due to its performance, PoE capabilities, and cost-effectiveness for wiring closet deployments. The CX 6300F series offers the flexibility and scalability needed for modern network environments, supporting both wired and wireless connectivity demands. It provides advanced features such as stackability, high-density PoE options, and the capability to support dynamic segmentation, which is essential for separating and securing different types of network traffic, such as corporate data and guest Wi-Fi access. This series is designed to meet the needs of a full-stack wired and wireless network in a large, multi-story office building, providing the necessary infrastructure for both current and future network requirements.

Question 7
'Don't Buy at Us' is a US-based retail company that is expanding Into Europe. They are expanding into EMEA with a regional headquarters called HQ2 inside The Netherlands.
Their US-based headquarters HQ1 was refreshed last year based on the Aruba ESP architecture. You have treated the design for HQ? based on the same design as HQ1. a two-tier architecture. The high level is shown below.
Switch BOM for this project based on Two Tier:
Collapsed Core: 2 x Aruba 8360-16Y2C in VSX (ISL 2 ICOG0E DAC)
Access Slack: 10 x Slack of Aruba 6200F 48G Class4 PoE 4SFP- 740W each stack has A members. VSF
with 10GbE VSF links) 12 x 10GbE uplink pet stack)
During the presentation of your design to the CTO of 'Don't Buy at Us' you were informed about the updated fiber infrastructure that Don't Buy at Us' has installed in HQ2.
The core stack is Installed in the MDF and per IOF there is one access stack installed. Based on best practice, what is the most cost-effective update to the switch BOM?
A)
B)
C)
D)
Answer : B
Option B is the most cost-effective solution, as it does not include long-range optics, which are unnecessary given the distances and fiber types specified. The 10GbE-SR optics are suitable for short-range connections up to 300 meters over OM3 fiber and would cover the needs of the longest fiber run mentioned, which is 250 meters. The 10GbE-LRM optics, while capable of reaching up to 220 meters over OM2 fiber, would not be necessary as the longest OM2 run is 71 meters, which is within the range of standard 10GbE-SR optics. Thus, Option B provides the required connectivity without incurring additional costs for long-range optics that are not needed given the fiber infrastructure of HQ2.
