In what two ways can Storage DRS load balance virtual machines? (Choose two.)
The correct answer is A. anti-affinity rules D. I/O latency. Storage DRS load balances virtual machines across datastores using I/O latency metrics to redistribute storage workloads and VM anti-affinity rules to separate VMs onto different datastores.

Why each option
Storage DRS load balances virtual machines across datastores using I/O latency metrics to redistribute storage workloads and VM anti-affinity rules to separate VMs onto different datastores.
VM anti-affinity rules in Storage DRS instruct SDRS to keep specified VMs on separate datastores, distributing storage load and preventing I/O contention between VMs that share heavy workloads.
Virtual storage controller assignment is not a metric or mechanism that Storage DRS uses for load balancing; SDRS operates entirely on storage-layer data such as space utilization and I/O latency.
Guest OS family is not a criterion recognized by Storage DRS; SDRS is storage-layer software that is agnostic to VM operating system type when making placement and migration decisions.
Storage DRS monitors per-datastore I/O latency and can invoke Storage vMotion to relocate VMDKs to datastores with lower latency, directly rebalancing storage I/O load across the datastore cluster.
