NEW QUESTION # 51
A utility failure causes a workstation to immediately shut down. Which of the following would help prevent this from reoccurring?
Answer: A
Explanation:
A "utility failure" implies a power interruption (brownout/blackout). The device that prevents an immediate shutdown during an outage is a UPS . Quentin Docter explains that a UPS stores energy in batteries and "if the power fails, the batteries can power the computer for a period of time so that the administrator can then safely power it down." He further notes UPS devices also protect against "power sags and even power outages" and may work with operating systems to shut down safely and automatically.
Mike Meyers' Lab Manual echoes the same: a UPS "continues to supply AC power to your computer during both brownouts and blackouts via a battery that is charged from the AC current." A surge suppressor is mainly for voltage spikes, not sustained backup power. A redundant PSU helps only if one PSU fails inside the system, and Docter explicitly states it "can't keep the system up and running if there is a power outage." Therefore, the best answer is B .

An incident report documents key details such as the cause of the outage, steps taken to resolve it, and measures to prevent recurrence. It is a post-mortem analysis often shared with stakeholders to improve future response.

"An incident report provides a summary of an event that disrupted normal operations and includes a timeline of what occurred, how the issue was diagnosed and fixed, and who was involved in the resolution".
This is reaffirmed in Travis Everett's All-in-One Guide:
"Documentation after an incident helps technical teams and management review the situation and learn from it. This is formalized in an incident report".
