HPE Aruba Certified Mobility Associate (ACMA) — Question 23

A customer needs a wired network solution that can recognize and prioritize a wide array of different types of traffic, including casual Web browsing, voice, video,
SAP Online, and file sharing.
The architect needs to choose between the Aruba 2930F or the 2540 Switch Series for the access layer switch. Why would the architect choose the 2930F rather than the 2540 Switch Series for this customer?

Answer options

• A. The 2930F Series supports LLDP-MED for detecting VoIP traffic, while the 2540 Series does not.
• B. The 2930F Series supports advanced routing, including multi-area OSPF, while the 2540 Series does not.
• C. The 2930F Series supports more options for class-based QoS policies that the 2540 Series.
• D. The 2930F Series can provide better congestion management with its much deeper buffers.

Correct answer: D

Explanation

The correct answer is D because the 2930F's deeper buffers allow it to handle more traffic without dropping packets, which is crucial for minimizing congestion and ensuring smooth performance for various types of traffic. Option A is incorrect as both switches can handle VoIP traffic, but the 2930F's advantage lies in congestion management. Option B is not relevant since the question focuses on traffic prioritization rather than routing capabilities. Option C, while true, does not address congestion management, which is critical for the customer's needs.
