The Aruba MC 7010 and 7024 are both designed for small to mid-sized campuses and branches, but they have some differences in their features and specifications. One of the main differences is the number and type of ports they offer. The MC 7010 has 16 10/100/1000BASE-T ports, while the MC 7024 has 8 10/100/1000BASE-T ports and 8 1000BASE-X SFP ports1. This means that the MC 7024 can support more APs that require fiber connections, such as the AP-387 or the AP-5352. The MC 7024 also supports 10G ports, which can provide higher bandwidth and performance for the network backbone3.

Therefore, if the customer needs to connect 20 APs directly to the MC, and some of them require fiber or 10G connections, the MC 7024 is a better choice than the MC 7010. The other options (A, B, and C) are not relevant for choosing between the MC 7010 and 7024, as both models can support up to 64 APs and 4096 users or devices, and both models can provide PoE+ on 12 ports1.

The transceivers that the architect should recommend for each pair of switches are two QSPF+ MPO. This option would provide 40 Gbps bandwidth per link, which is enough to meet the customer requirement of 80 Gbps for the link aggregation. The QSPF+ MPO transceivers use a single multi-fiber connector that can support up to 12 fibers, which is compatible with the customer’s existing OM4 multi-mode fiber infrastructure. The QSPF+ MPO transceivers also support distances up to 100 meters, which is sufficient for the customer’s inter-building connections.

The other options are not optimal for the customer requirement because they either provide insufficient bandwidth or require additional fiber strands. Two QSPF+ BiDi transceivers would provide only 20 Gbps bandwidth per link, which is half of the customer requirement. Eight SFP+ LR or SR transceivers would provide 80 Gbps bandwidth per link, which is more than the customer requirement, but they would also require eight fiber strands per link, which is more than the customer’s available fiber infrastructure. References:

The Aruba Mobility Master (MM) hardware appliances are designed to manage large-scale networks. The MM-HW-10K model is capable of managing up to 10,000 devices, which would be sufficient for the customer’s requirement of supporting about 1,500 client APs and a maximum of about 20,000 wireless clients1. Two MM-HW-10K appliances would allow for an active and standby deployment, providing redundancy and ensuring network reliability2.
