Check the core maintenance reasoning

You have inspected the source sensors, anomaly detection, health scores, and the five-category ontology in sequence. Before stating the final decision, distinguish the concepts that can look similar. This quiz has no passing score and does not lock the next chapter.

Question 1 CNC-01 scores 4.00 and is MEDIUM; CNC-07 scores 4.22 and is HIGH. What split the grade?
The 0.22 gap makes CNC-07 statistically more dangerous.CNC-07's source row carries a HIGH_TEMP condition signal.Temperature sensors are configured to receive a higher grade than others.
Question 2 Raising sigma from 3.0 to 4.1 leaves what, out of the six anomalies?
Only the four HIGH rows carrying a condition signal; the two caught by statistics drop out.Only CNC-03, whose z-score exceeds 4.1.All six, because the threshold changes severity but not membership.
Question 3 Once technician, location, and shift are connected, how should the four HIGH machines be assigned?
Queue all four in one line, because they all fall in the day shift.Sequence only CNC-03 and CNC-09, whose technician overlaps; run CNC-05 and CNC-07 in parallel.Give LOC-A1 and LOC-A2 equal priority, since both hold two anomalies.
Question 4 What is this workshop's conclusion when all four machines have a health score of 90?
Inspect only CNC-03 and return the other three to normal operation.Inspect all four machines, starting with CNC-03 under the published tie-break rule.Keep all four machines running until another data point breaks the tie.
