A software development company has 700 employees who work from home. The company also has small offices located in different cities throughout the world. During working hours, they use RAPs to connect to a datacenter to upload software code as well as interact with databases.
In the past two months, brief failures have occurred in the 7240XM Mobility Controller (MC) that runs ArubaOS 8.3 and terminates the RAPs. These RAPs disconnect, affecting the users connected to the RAPs. This also causes problems with code uploads and database synchronizations. Therefore, the company decides to add a second 7240XM controller for redundancy.
How should the network administrator deploy both controllers in order to provide redundancy while preventing failover events from disconnecting users?
A. Connect both controllers with common VLANs, and create an L2-connected cluster using public addresses in the internet VLAN.
B. Connect both controllers with common VLANs, and create an HA fast failover group with public addresses in the internet VLAN.
C. Connect both controllers with different VLANs, and create an L2-connected cluster using private addresses in the internet VLAN.
D. Connect both controllers with common VLANs, and configure LMS/BLMS values equal to public addresses in the internet VLAN.
