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?
A. The 2930F Series supports LLDP-MED for detecting VoIP traffic, while the 2540 Series does not.
B. The 2930F Series supports advancing 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.

C is correct. Class-based is a feature of 2930F and not 2540
B – 2540 doesn’t support ospf

Answer is C
A is wrong because both support LLDP-MED
B is wrong because Access layer does not do routing so OSPF is pointless for a decision factor.
D is wrong because both support deeper buffers
2540 doesn’t support OSPF, 2930F does…
Only OSPF is different for both switches, so must be answer B.
