Question 420
At the Quayford energy utility, a shared Central template update unexpectedly modifies unrelated switches in other sites. Which ongoing control best prevents this issue from recurring?
Explanation
Correct Answer
After implementation, the team should review scope membership and template diffs before deployment as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Quayford energy utility.
Incorrect Answers
a backup from different hardware or release cannot be assumed directly reusable, the required evidence must show that a test restore identifies unsupported features and re-establishes intended forwarding. The offered alternative applies that mechanism: Keep platform migration mappings in backup runbooks. The reported facts point to a different controlling condition: a global or group template change may affect more devices than the operator expects, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required recurrence control.
Track resource baselines and software version regressions. Its technical scope is explained by: it requires the team to track resource baselines and software version regressions. In this question, the decisive issue is: a global or group template change may affect more devices than the operator expects, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct recurrence control.
Monitor client authentication time and service dependencies. This option is based on the following distinct technical behavior: user experience can degrade in identity services even with healthy switching and routing. The present question instead depends on this mechanism: a global or group template change may affect more devices than the operator expects, rather than merely a monitoring or presentation issue. That difference matters for the requested recurrence control.
