Which RQL string returns a list of all TERMINATED Google Compute Engine instances?

• A. Config where api.name = 'gcloud-compute-instances-list' = TERMINATED
• B. Config where api.name = 'gcloud-compute-instances-list' and json.rule = status contains TERMINATED
• C. Config where api.name = 'gcloud-compute-instances-list' and json.rule = status == TERMINATED
• D. Config where api.name = 'gcloud-compute-instances-list' and json.rule = is TERMINATED

Answer: (B)

The correct answer retrieves a list of all TERMINATED Google Compute Engine instances by correctly forming a query that specifies the API and the condition under which the instances should be filtered. The structure of this RQL string indicates that it uses the 'gcloud-compute-instances-list' API and applies a filter to the ‘status’ attribute in the returned JSON data. In this specific case, the phrase “json.rule = status contains TERMINATED” effectively allows for matching any instance with a status that includes the string “TERMINATED”. This is particularly useful in cases where the status may have other values associated with it or be part of a longer status description, ensuring that any mention of 'TERMINATED' is captured. For instance, if a status could be "TERMINATED_SINCE_LAST_MONTH" or similar variations, this string would still match, while narrowing down to only those instances that have terminated statuses. This flexibility is significant when assessing instances based on their operational states in cloud environments. In contrast, other answers present slightly incorrect syntax or conditions that do not appropriately filter or specify the statuses of the instances correctly. Each of those alternatives may not effectively capture all instances that are considered "TERMINATED", thus failing to fulfill the objective
