An administrator is creating a vNetwork Standard Switch with Service Console and
VMkernel networking. The administrator has two uplinks attached to the switch, but
wants to separate the Service Console and VMkernel traffic to the two uplinks. Which of
the following Load Balancing Policies will guarantee this, even if additional management
or virtual machine traffic is added to the switch in the future?
A.
Route based on source MAC hash
B.
Use Explicit Failover
C.
Route based on the originating port ID
D.
Route based on IP hash
Explanation:
ESX Configuration Guide ESX 4.0 vCenter Server 4.0, page 43.Load Balancing Specify how to choose an uplink.
Route based on the originating port ID – Choose an uplink based on the virtual port where
the traffic entered the virtual switch. If additional management or virtual machine traffic
is added to the switch under this policy, it is possible that different uplinks could be used.
Route based on ip hash – Choose an uplink based on a hash of the source and destination
IP addresses of each packet. For non-IP packets, whatever is at those offsets is used to
compute the hash. Selection is based on the source and destination IP address under this
policy, so it is possible based on the connections IP characteristics that different uplinks
could be used.
Route based on source MAC hash – Choose an uplink based on a hash of the source
Ethernet. If additional management or virtual machine traffic is added to the switch, since
selection is based on the source MAC address, so it is possible that different uplinks
could be used.
Use explicit failover order – Always use the highest order uplink from the list of Active
adapters which passes failover detection criteria. This is the only policy that specifies the
order of uplinks regardless of any connectivity information.
