To address traffic bottlenecks on a Citrix ADC MPX, which change is most appropriate to increase bandwidth?

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

Answer: (D)

To boost bandwidth and reduce traffic bottlenecks, you want to combine multiple physical links into a single, higher-capacity path. This is done with link aggregation (LACP). By adding another 10G port to the switch and configuring LACP on both the Citrix ADC MPX and the switch, you create a port-channel that distributes traffic across both links. That effectively doubles the available bandwidth for the aggregated path and provides better load balancing, which directly addresses the bottleneck.

Simply adding ports or VLANs without forming an aggregated link won’t yield the same throughput gains, since traffic would still be constrained by a single 10G path. Purchasing another appliance is costly and slower than upgrading the existing link capacity. So, using an additional port together with LACP is the right approach.
