Oh shoot, it could either be a battery backup or line conditioner. They both protect against brownouts.
This is from Jason Dion: OBJ-4.3: A blackout is a total loss of power in a particular area. A brownout is a reduction in or restriction on the availability of electrical power in a particular area. The irregular power supply during the brownout can ruin your computer and other electronic devices. Electronics are created to operate at specific voltages, so any fluctuations in power (both up and down) can damage them. To protect against a brownout, you can use either a battery backup or a line conditioner. To protect against a blackout, a battery backup should be used.
So, I'll stick with battery backup as it protects against blackouts too and cross my fingers they don't give me this question, or give me the option to choose two answers.
A line conditioner is device mainly used for power factor compensation. This device could operate as active electrical harmonic filters which measure the Total Harmonic Distortion (THD) of the electric spectrum and compensate for this disturbances. However i have never seen them used for servers or computers but mostly at power generations stage instead of passive capacitive banks. On the other hand UPSs are found in every office, at land and sea ;)
While a Battery Backup (UPS) can help during a brownout, a Line Conditioner is more specialized for this purpose. But you’re correct that both can be part of a comprehensive approach to protecting sensitive electronic equipment. However... Ive seen this question before and the answer was A. Prob comptia expectation.
I would go with - line conditioner
This is from COMPTIA CertMaster
Line Conditioners
Larger industrial power filter units called line conditioners or Power Distribution Units (PDUs) can be used to protect entire power circuits from the effects of surges or brownouts, but they are unable to remove or reduce the effects of blackouts.
Lets vote this one up. A line conditioner (D) helps keep the power steady during brownouts and surges. a battery backup is for blackouts. - according to CompTIA official texts.
CompTIA makes a distinction between Line Conditioners and UPS/battery backups. Even though a UPS protects against brownouts, its purpose is to protect against blackouts, while a line conditioner is for brownouts and surges.
Answer Is D
Surge protectors also help prevent EMI/RFI line noise from interfering with equipment performance.
Line conditioners are your best defense against brownouts, which are low-voltage power sags that can cause your equipment's internal power supply and circuitry to work harder.
Line conditioners are your best defense against brownouts, which are low-voltage power sags that can cause your equipment’s internal power supply and circuitry to work harder. Frequent exposure to brownouts can overheat these sensitive components, leading to equipment failure. Line conditioners automatically adjust low and high voltages to provide safe computer-grade power. In addition to voltage regulation, line conditioners offer surge protection and line noise filtering.

The answer is a line conditioner, the question asks for protection from a brownout which is a power sag. A blackout would require a battery backup because that's when they actually begin to work.
Exactly!!
Line Conditioners
Voltage Regulation, Surge Protection and Line Noise Filtering
Line conditioners are your best defense against brownouts, which are low-voltage power sags that can cause your equipment’s internal power supply and circuitry to work harder. Frequent exposure to brownouts can overheat these sensitive components, leading to equipment failure. Line conditioners automatically adjust low and high voltages to provide safe computer-grade power. In addition to voltage regulation, line conditioners offer surge protection and line noise filtering.
UPS Systems
Voltage Regulation (Line-Interactive and On-Line Models), Battery Backup, Surge Protection and Line Noise Filtering
UPS systems are your best defense against downtime, damage and data loss. All UPS systems provide battery backup to keep equipment up and running through short blackouts and brownouts, providing you with enough time to save data and shut down properly during longer outages. A UPS system can also keep equipment powered during transfer to generator power.
Something I found in the 1001 exam is that, if a question listed here has 2 competing potentially correct answers, the actual exam has likely had one of those options removed to correct it by now. If you remember both options from here then you can pick the remaining option in the exam with certainty.
It's A, but they should have called it a UPS instead. Line conditioners only clean up "dirty" power. They do not provide additional voltage in the event of a low voltage situation, aka brownout, like a BBU/UPS can.
guys this is D. A brownout is not a blackout. it is a fluctuating power, usually lower in voltage. this quote is directly from comptia. -A line conditioner monitors AC electricity. If the voltage is too low, the line conditioner boosts voltage to the proper range. If the voltage level is too high, the line conditioner clamps down the voltage and sends the proper amount to the computer. this is basically the definition of a brownout btw.
