In a Citrix ADC MPX deployment, how can you increase uplink bandwidth without purchasing a new appliance?

• A. Purchase another Citrix ADC MPX appliance.
• B. Add two more 10 Citrix ADC ports to the network and configure VLAN.
• C. Add another 10G port to the switch and configure Link Aggregation Control Protocol (LACP).
• D. Plug another 10G Citrix ADC port into the router.

Answer: (C)

Boosting uplink bandwidth on a Citrix ADC MPX without new hardware comes from combining multiple physical links into one logical link using Link Aggregation (LACP). By adding a second 10G uplink port and configuring LACP on both the ADC and the upstream switch, those ports form a single 20G (or more, depending on port count) channel. This not only increases the effective capacity available to upstream traffic but also provides redundancy if one link fails, all without purchasing another appliance.

VLANs alone don’t increase the actual throughput into the core network; they segment traffic but don’t create a higher-capacity path. Simply plugging a second 10G port into the router without establishing a bound port-channel with LACP won’t automatically merge the links for a single stream’s bandwidth. Purchasing another appliance is unnecessary for this goal, and while adding a second port without proper aggregation might offer an extra path, it won’t reliably deliver the summed bandwidth you get from a properly configured LACP trunk.

So, the optimal approach is to add a second 10G uplink and enable LACP to create a single, higher-bandwidth uplink with built-in redundancy.
