CompTIA Updated FC0-U71 Exam Questions and Answers by francisco

The correct answer is C. UPS. A UPS, or uninterruptible power supply, provides temporary battery power during a power outage. This gives users or systems enough time to save work and shut down safely. Cloud storage, external drives, and file servers can store data, but they do not provide temporary power during an outage.

Exact Extract/Reference: The CompTIA Tech+ Study Guide defines a UPS as “a battery backup system” and states that during a power outage or brownout, it can supply power “for a limited amount of time and provide for a graceful shutdown.” The guide also states that if power fails, UPS batteries can power the computer long enough for the administrator to safely power it down.

Account logs provide details about authentication attempts and can confirm whether a user successfully logged in or was denied access.

“Authentication events are recorded in system and application logs, helping verify login success or failure.” — CompTIA ITF+ Security Concepts

Correct answer: A

The CompTIA Tech+ Study Guide defines:

“Devices that use radio frequency (RF) transmit a very limited range, typically only a few inches or so. This technology is fairly common in mobile payment applications. Because of the short distances involved, a related term you’ll see is near-field communication (NFC).”

NFC allows devices such as smartphones to securely transmit payment data over short distances—precisely the method used in vending machine purchases.

Verified Reference:

Chapter 2: Peripherals and Connectors — “Wireless Connections: NFC” (p. 99).

Task management utilities like Task Manager in Windows are used to monitor and manage running applications and processes, including ending unresponsive ones.

“Task Manager is used to view and end processes or applications that are not responding.” — CompTIA ITF+

Correct answer: B
