2V0-622D · Question #180

vSphere DRS helps to balance virtual machines with available resources in a vSphere cluster. What three types of resources can be taken into account for balancing? (Choose three.)

The correct answer is B. RAM D. CPU E. physical NIC saturation of an ESXi host. vSphere DRS balances workloads across cluster hosts using CPU, RAM, and physical network bandwidth - not storage latency or per-VM NIC metrics.

Why each option

vSphere DRS balances workloads across cluster hosts using CPU, RAM, and physical network bandwidth - not storage latency or per-VM NIC metrics.

Avirtual NIC saturation of a virtual machine

DRS does not monitor per-VM virtual NIC saturation; network awareness in DRS operates at the physical host uplink level, not the individual VM vNIC level.

BRAMCorrect

RAM (memory) utilization is one of the two primary DRS balancing dimensions; DRS migrates VMs via vMotion when memory pressure is imbalanced across hosts.

Cstorage latency

Storage latency is the domain of Storage DRS (SDRS), which operates on datastores independently from compute DRS balancing.

DCPUCorrect

CPU utilization is the other primary DRS balancing dimension; DRS calculates host CPU load and migrates VMs to reduce hotspots.

Ephysical NIC saturation of an ESXi hostCorrect

Network-Aware DRS, introduced in vSphere 6.5, incorporates physical NIC saturation at the ESXi host level to avoid placing VMs on hosts with congested uplinks.
