An administrator is configuring the Failover Order option on a vSphere Distributed Switch. Which two options should be used with IP-hash load balancing? (Choose two.)
The correct answer is A. Active Uplinks C. Unused Uplinks. IP-hash load balancing distributes traffic across all uplinks simultaneously based on source/destination IP, requiring all uplinks to be active - standby uplinks are incompatible with this policy.

Why each option
IP-hash load balancing distributes traffic across all uplinks simultaneously based on source/destination IP, requiring all uplinks to be active - standby uplinks are incompatible with this policy.
Active Uplinks must be used because IP-hash requires all participating uplinks to be active at the same time, distributing traffic across them concurrently based on a hash of the IP addresses.
Standby Uplinks are incompatible with IP-hash load balancing because IP-hash does not support a failover model where uplinks wait in reserve - all uplinks must be active or unused.
Unused Uplinks is the only other valid state for uplinks when using IP-hash, because standby uplinks would imply a failover model that conflicts with how IP-hash distributes load across all uplinks simultaneously.
Override Failover Order is not a valid uplink state category in the Failover Order configuration - it is not one of the three assignable states (Active, Standby, Unused).
