When an explicit failover order has not been configured on a virtual switch with multiple
uplinks, what determines which uplink is used when a failover event occurs?
The uplink with the shortest route
The next available uplink on the list
The reported uptime for the surviving uplinks
The first available uplink that reports a positive Link State
Networking Virtual Machines Jon Hall Technical Trainer, VMWORLD 2006, slide 27.
Failover is implemented by the VMkernel based upon configurable parameters
1. Failover order: Explicit list of preferred links (uses highest-priority link which is up)
2. 1. Maintains load balancing configuration
2. Good if using a lower bandwidth standby NIC
3. Rolling failover — preferred uplink list sorted by uptime [C above]
The uplink with the shortest route – all uplinks are on the same network and so have the
same route [A is incorrect]
The next available uplink on the list has not been defined if explicit failover order is not
selected [B is incorrect]
