An administrator is troubleshooting a virtual machine performance issue using vRealize Operations.

C. Risk > Time Remaining
D. Risk > Stress
Correct Answer: AD

Explanation:
The Workload badge shows how hard an object is working. A higher workload score indicates that an object is doing more work. Obviously, you don’t want objects out there doing zero work, as that is waste but, as the same time, you also don’t want objects completely maxed out with a workload score of 100 either. Workload is an absolute measurement that calculates the demand for a resource divided by the capacity of an object. Resources might include CPU, memory, disk I/O, or network I/O. vC Ops will help you to balance workload across your resource objects effectively.
Stress badge reports the stress that an object is under. Just as your stress level is related to your workload, so is the stress score in vC Ops. The stress score is based on long-term high workload (where the workload score is instantaneous workload). Stress in the virtual infrastructure might come from VMs that are undersized, hosts that are overloaded, or datastores with consistently high I/O latency. Stress is reported between 0 and 100 with 100 being very high stress and 0 being no stress.
