The EtherChannel between your LAN switch and the Internet router is not load-balancing
efficiently. On the switch, there are several workstations with valid IP ranges. Which load-balance
algorithms can you use in the switch in order to optimize this load balancing? (Choose four.)

A.
source IP address

B.
destination IP address

C.
per-packet load balance

D.
destination MAC address

E.
source MAC address

Explanation:
EtherChannel load balancing can use MAC addresses, IP addresses, or Layer 4 port numbers
with a Policy Feature Card 2 (PFC2) and either source mode, destination mode, or both. The
mode you select applies to all EtherChannels that you configure on the switch. Use the option that
provides the greatest variety in your configuration. For example, if the traffic on a channel only
goes to a single MAC address, use of the destination MAC address results in the choice of the
same link in the channel each time. Use of source addresses or IP addresses can result in a better
load balance. Issue the port-channel load- balance {src-mac | dst-mac | srcdst-mac | src-ip | dst-ip
| src-dst-ip | src-port | dst-port | src-dst-port | mpls} global configuration command in order to
configure the load balancing.
Issue the show etherchannel load-balance command in order to check the frame distribution

policy. You can determine which interface in the EtherChannel forwards traffic, with the frame
distribution policy as a basis.
Issue the remote login switch command to log in remotely to the Switch Processor (SP) console in
order to make this determination. Then, issue the test etherchannel load-balance interface portchannel number {ip | l4port | mac} [source_ip_add | source_mac_add | source_l4_port]
[dest_ip_add | dest_mac_add | dest_l4_port] command.
