HPE Aruba Certified Mobility Associate (ACMA) — Question 27

An architect needs to plan the bandwidth for two Aruba 7240 Mobility Controllers (MCs) which will connect to the network core. The customer indicates that four
10 GbE links between the network core and the data center will be adequate. The customer expects almost all traffic in the network will be wireless. The customer expects up to 25 Gbps upstream traffic from wireless clients and up to 35 Gbps downstream to wireless clients. The customer requires the MCs to be able to continue to forward traffic if up to one link fails, but lower performance during the failover situation is permissible.
What are the minimal links to meet these requirements?

Answer options

Correct answer: D

Explanation

The correct answer is D, as four 10 GbE links on each MC provide a total of 80 Gbps, which adequately accommodates the required 25 Gbps upstream and 35 Gbps downstream traffic, ensuring redundancy. Options A and C do not supply enough bandwidth, while option B offers more capacity than necessary, given the customer's requirements.
