Question 1 of 30

Following a severe outage of the primary customer portal, which directly impacted sales transactions, the incident management team has identified a recent software patch as a likely contributor. However, the precise mechanism by which this patch caused the failure remains unconfirmed, and the business is experiencing significant financial losses due to the prolonged downtime. What is the most prudent immediate action to take, adhering to the principles of ISO/IEC 20000 service management?

Implement a documented workaround to restore portal functionality, and simultaneously trigger a formal problem investigation to identify and rectify the root cause of the issue.
Immediately uninstall the recent software patch across all affected systems to revert to the previous stable state, without further diagnostic steps.
Escalate the incident to the highest organizational leadership tier, requesting immediate external expert consultation for root cause analysis before any service restoration attempts.
Halt all further diagnostic efforts and focus exclusively on definitively pinpointing the exact root cause before attempting any service restoration or workaround implementation.
