FC0-U71 Practice Question: A technician is recommending a device to protect…
A technician is recommending a device to protect a server from data loss during a power outage. Which device should the technician recommend?
⚠ Common exam trap
Many candidates confuse a surge protector's ability to protect against spikes with the UPS's ability to provide continuous power during an outage, or they may think a generator is suitable despite its startup delay and lack of instantaneous failover.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Uninterruptible Power Supply (UPS)
An Uninterruptible Power Supply (UPS) provides battery backup power to the server during a power outage, allowing for a safe shutdown or continued operation until power is restored. This directly prevents data loss by ensuring the server does not abruptly lose power while writing data to disk. Unlike other devices, a UPS combines surge protection with battery backup, making it the correct choice for this scenario.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Uninterruptible Power Supply (UPS)
Why this is correct
A UPS supplies battery-backed power during an outage, letting the server shut down cleanly or ride through brief interruptions. This directly prevents data loss from abrupt power removal, satisfying the stem's requirement to protect the server during a power outage.
- ✗
Generator
Why it's wrong here
A generator supplies power only after starting, typically taking seconds to minutes, so the server still drops during the gap and loses data. It is tempting because generators do sustain long outages, making them the right choice when the requirement is extended runtime rather than bridging the immediate interruption.
- ✗
Power strip
Why it's wrong here
A power strip merely distributes mains power to multiple sockets and contains no battery or inverter, so it cannot supply the server when mains fails. It is tempting because it does provide additional outlets and often basic surge clamping, which is the right choice when the need is simply connecting more equipment.
- ✗
Surge protector
Why it's wrong here
A surge protector only clamps transient voltage spikes on the mains supply; it provides no stored energy, so the server still loses power instantly during an outage. It is tempting because surge protectors genuinely defend against lightning and switching transients, which is the right choice when the threat is voltage spikes rather than an outage.
