Question

If you have enabled LAG on a WLC with eight distribution system ports, what is true by default?

a) LAG will be enabled on all eight ports
b) LAG will be enabled only on one physical port
c) LAG will aggregate all ports using LACP protocol
d) LAG will cause each port to trunk independently

Answer 1

Option (A), When LAG is enabled on a WLC with eight distribution system ports, it is enabled on all eight ports by default, increasing bandwidth and providing redundancy.

Step-by-step explanation:

If you have enabled Link Aggregation (LAG) on a Wireless LAN Controller (WLC) with eight distribution system ports, option a) LAG will be enabled on all eight ports is true by default. Consequently, when LAG is enabled, all active ports participate in the aggregation, behaving as a single port channel. This means that there's an increase in bandwidth by combining multiple links, as well as providing redundancy—if one link in the LAG fails, the system continues to transfer data through the remaining links. It is important to note that while enabling LAG simplifies network design by reducing the number of switch ports used, it requires a switch that supports LAG and usually the Link Aggregation Control Protocol (LACP) for dynamic link aggregation.
