NEW QUESTION # 270
A technician is working on a RAID 1 array that is apparently degraded. The technician verifies the RAM and power are both operating as expected. Which of the following can the technician do to further isolate the issue?

A. Perform individual drive diagnostics.
B. Reconfigure the array as RAID 0.
C. Rebuild the RAID array.
D. Run the chkdsk /i command.

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
A degraded RAID 1 array usually means one of the drives has failed or is failing. The correct next step is to run diagnostics on each drive to identify the faulty one. RAID 1 uses mirroring, so one good drive should still contain all the data.
* Option B: chkdsk checks file system integrity, not hardware drive health.
* Option C: Rebuilding should only occur after identifying and replacing a faulty drive.
* Option D: RAID 0 offers no redundancy and would destroy data in this context.
CompTIA A+ Core 1 Exam Objective Reference:
* Objective 3.5: Given a scenario, troubleshoot problems related to storage devices.

NEW QUESTION # 271
Which of the following internet connection types is most likely to be used in remote locations?

A. Fiber
B. Cable
C. DSL
D. Cellular
E. Satellite

Answer: E

Explanation:
Satellite internet is most commonly used in remote areas where wired infrastructure (e.g., fiber or cable) is unavailable. It relies on satellite communication, making it suitable for isolated locations.
* Why Not A (Fiber): Fiber requires physical infrastructure, which is rarely available in remote areas.
* Why Not B (Cable): Cable internet relies on coaxial infrastructure, which is often unavailable in remote locations.
* Why Not D (DSL): DSL depends on existing telephone lines, which may not reach remote areas.
* Why Not E (Cellular): Cellular can work in remote areas, but satellite is often the only option for extremely isolated locations.
CompTIA A+ Exam Reference: Core 1 (220-1101), Section 2.7, internet connection types.

NEW QUESTION # 272
Which of the following wireless technologies would a company most likely implement for inventory management?

A. RFID
B. Bluetooth
C. 5G
D. NFC

Answer: A

Explanation:
Explanation
RFD stands for Radio Frequency Identification, which is a technology that uses radio waves to identify and track objects that have RFID tags attached to them. RFID tags are small devices that store information and can be read by RFID readers without direct contact or line of sight. RFID can be used for inventory management, as it can provide real-time visibility and accuracy of the location, quantity, and status of the items in a warehouse, store, or supply chain .

NEW QUESTION # 273
A customer's Windows tablet PC was dropped and is no longer responding to touch input on the left half of the screen. The screen protector has several scratches. but the glass is not broken. Which of the following should a technician do to diagnose the issue?

A. Perform a factory reset.
B. Replace the damaged screen protector
C. Update the device drivers.
D. Test the digitizer

Answer: D

Explanation:
The digitizer is the component that converts the touch input into electrical signals that are processed by the tablet. If the digitizer is damaged or malfunctioning, it may not register the touch input correctly or at all. The technician can test the digitizer using a diagnostic tool or by replacing it with a known good one. Updating the device drivers, replacing the damaged screen protector, or performing a factory reset are unlikely to fix the issue, as they do not address the hardware problem.
