In an MPX environment with limited bandwidth, what approach increases uplink bandwidth without buying another appliance?

• A. Add two more ports and VLAN
• B. Plug another port into router
• C. Add port to switch with LACP
• D. Purchase another appliance

Answer: (C)

Using link aggregation (LACP) to create a port channel across multiple uplink ports is the way to boost uplink bandwidth without buying a new appliance. When you bond two or more NICs from the MPX to a switch that supports LACP, they form a single logical link. The switch and the MPX coordinate to distribute traffic across all member links, effectively increasing the total available bandwidth to the upstream network and providing redundancy if one link fails. This leverages what you already have, without adding hardware costs, and is only limited by the combined speed of the bonded links and the switch’s capabilities. Adding more ports with VLANs alone doesn’t automatically increase uplink capacity, since the traffic would still be constrained by the single upstream path unless those ports are actually bonded into one channel. Plugging into a router creates a separate path but doesn’t aggregate bandwidth. Purchasing another appliance adds hardware rather than increasing the capacity of the existing uplink.
