You have a router connected to the switch via an EtherChannel. Which type of load- balancing criteria will you use to make sure you have the most optimal load balancing?

A. Source MAC address
B. Destination MAC address
C. Source and destination IP address
D. Source and destination MAC address

C. When you want optimal load balancing, you would configure the source and destination IP address. On some versions of Cisco IOS, you can configure the source and destination IP address as well as the source and destination ports. Although this creates the most optimal load balancing, it creates a high amount of latency since layer 4 information must be calculated.
