Which RQL string returns a list of all Azure virtual machines that are not currently running?

• A. Config where api.name = 'azure-vm-list' AND json.rule = powerState contains "running"
• B. Config where api.name = 'azure-vm-list' AND json.rule = powerState = "running"
• C. Config where api.name = 'azure-vm-list' AND json.rule = powerState does not contain "running"
• D. Config where api.name = 'azure-vm-list' AND json.rule = powerState = "off"

Answer: (C)

The correct choice accurately identifies the condition needed to filter Azure virtual machines based on their power state. In Azure, virtual machines can be in various power states, one of which is "running." The goal of the query is to retrieve a list of virtual machines that are not currently running, which means they must be in any power state other than "running." The use of 'does not contain "running"' in the chosen option allows the query to encompass all possible states that are not "running," including "stopped," "deallocated," or any other state that indicates the VMs are not actively running. This approach effectively identifies all virtual machines that are not currently operational. On the other hand, some options mistakenly focus solely on identifying machines that are "running," which does not meet the requirement of finding those that are not in that state. Others may incorrectly specify states like "off," which is just one of several non-running states and does not encompass the full range of possible non-running conditions. Thus, the chosen option provides the most comprehensive and correct method to achieve the desired result.
