220-1102 Question 228
Single answerContinuityA small medical billing office is located in an area that frequently loses power during summer storms. During a recent outage, employees could not access the shared drive for patient billing files, and several desktops shut down abruptly. Management wants to reduce downtime and prevent data corruption during short power interruptions while allowing staff to save work and shut systems down cleanly during longer outages. Which solution best supports business continuity for this scenario?
- A
Install an uninterruptible power supply (UPS) for the file server and critical networking equipment, and configure graceful shutdown settings
- B
Replace all desktop power supplies with higher-wattage models so the systems can handle unstable voltage
- C
Deploy a screen lock policy with shorter timeout values so systems are protected during outages
- D
Move user documents to local desktop folders so employees can keep working if the network goes down
Show answer and explanation
Correct answer: A
Explanation
The best answer is to use a UPS for critical systems and configure graceful shutdown behavior. In A+ Core 2, continuity focuses on keeping business operations available during disruptions and minimizing downtime. For short power interruptions, a UPS is one of the most practical and common solutions because it supports availability and helps prevent data corruption from sudden loss of power. In a small office, protecting the file server and key network devices such as switches and routers is often more important than placing every endpoint on battery backup. This aligns with common business continuity and disaster recovery best practices: identify critical systems, maintain temporary power for those systems, and ensure controlled shutdown if the outage exceeds battery capacity. Vendor documentation for UPS platforms commonly includes power event management and automated shutdown features, which directly support continuity objectives.
- A. Correct.
Correct. A UPS is a standard continuity control for short-term power events. It provides temporary battery power, can condition power depending on the model, and allows critical systems such as servers and switches to remain available long enough for users to save work or for systems to shut down gracefully. Configuring the UPS management software to trigger an orderly shutdown helps prevent file system corruption and supports business continuity.
- B. Incorrect.
Incorrect. Higher-wattage power supplies do not provide backup power during an outage and do not address continuity planning. They may supply more power capacity to components, but they cannot keep a computer running when utility power fails. This distractor reflects the misconception that a stronger PSU can compensate for external power loss.
- C. Incorrect.
Incorrect. A screen lock policy is a useful security control, but it does not maintain operations or protect against abrupt shutdowns caused by power outages. This option confuses security best practices with availability and continuity objectives.
- D. Incorrect.
Incorrect. Storing files only on local desktops reduces central availability, complicates backup, and increases the risk of data loss if a desktop fails during a power event. While offline access can be part of some continuity strategies, simply moving business files to unmanaged local folders is not an appropriate or reliable continuity solution.
