HPE Aruba Certified Associate (ACA) – Network Security — Question 22

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 sq m). Data centers are all offsite 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 modem 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 would like to ensure full wireless coverage in its 40 m x 40 m (130 ft x 130 ft) auditorium during company functions while maintaining the fewest APs for aesthetic purposes. Wi-Fi6 APs are a minimum requirement.
Which AP series would you use in the auditorium’s 1,000 seats with a maximum take rate of 80%?

Answer options

Correct answer: A

Explanation

The AP555 is suitable for the auditorium due to its ability to handle high-density environments and maintain strong performance, which is critical given the 800 users expected. The AP577, while also capable, is designed for outdoor use and may not be as effective indoors. The AP515 does not support the same high capacity as the AP555, and the AP635, although powerful, is not the best fit for the specific requirements of this project considering the balance of coverage and aesthetics.
