HPE6-A47 Exam Topic 2 Question 16 Discussion:
Question #: 16
Topic #: 2
An Aruba wireless solution for a very high density (VHD) wireless solution consists of a Mobility Master (MM) and two Mobility Controllers (MCs). What is the best practice design for routing the wireless traffic?
A.
The MCs provide the default gateway services for wireless devices and use static routers.
B.
The MCs act at Layer2, and the MM acts as the default gateway.
C.
The MCs act at Layer2, and core routing switches act as the default gateway.
D.
The MCs provide the default gateway services for wireless devices and use OSPF.
This answer is correct because it follows the best practice design for routing the wireless traffic in a VHD wireless solution. By having the MCs act at Layer2, the architectcan enable the use of clustering, which provides high availability, load balancing, and seamless roaming for wireless users. By having the core routing switches act as the default gateway, the architect can avoid tunneling the wireless traffic to the MCs, which reduces the network overhead and latency. This also allows the core routing switches to apply security policies and QoS to the wireless traffic based on the user roles assigned by the MCs. References:
