Question #23
A technician is troubleshooting a PoE phone that will not turn on. When a laptop is plugged directly into the switchport for the phone the technician sees a data link LED and activity.
Which of the following tools should the technician use to verify PoE availability to the phone?
- A . Network tap
- B . Cable tester
- C . Loopback plug
- D . Toner probe
Correct Answer: B
B
Explanation:
Reasoning: A cable tester capable of testing Power over Ethernet (PoE) functionality can verify whether the switchport is providing the required power to the phone. This tool measures both the presence of data and the voltage or wattage being provided through the Ethernet cable. This is the most effective way to confirm that PoE is available on the port.
Why the Other Options Are Incorrect:

Question #24
Which of the following describes the function of an injector?
- A . To provide only data connectivity
- B . To supply power across a cable
- C . To improve wireless performance
- D . To extend a network connection
Correct Answer: B
B
Explanation:
A PoE injector is used to add power to an Ethernet cable, enabling the cable to deliver both power and data. This is crucial when connecting to PoE-enabled devices like IP cameras or wireless access points that are far from power outlets.

Question #25
A user experiences a random BSOD while using a computer, but the operating system recovers as expected.
Which of the following symptoms would indicate the issue is related to RAM?
- A . Wrong BIOS configurations
- B . Continuous reboots
- C . Distended capacitors
- D . POST code beeps
Correct Answer: D
D
Explanation:
D. POST Code Beeps:
During the Power-On Self-Test (POST), the BIOS performs checks on system hardware, including
RAM. If the RAM is faulty, POST may produce a series of beep codes indicating memory issues.
These beep codes are often the first sign of RAM-related problems, especially if the BSOD occurs
randomly.

Question #26
A company is testing the latest model of a laptop. After turning on the laptop, there is a noticeable burning smell.
Which of the following steps should a technician take to troubleshoot the laptop issue? (Select two).
- A . Turn it off and disconnect all power sources.
- B . Submit an emergency request to the local facilities manager.
- C . Check for foreign objects, liquid spills, and internal damage.
- D . Contact the vendor and submit a return request.
- E . Remove the device from the MDM.
- F . Try an alternate AC adapter.
Correct Answer: A,C
A,C
Explanation:
When a technician encounters a burning smell, it is a critical safety issue. The first response must be to immediately power down and disconnect the device from all power sources to prevent electric shock, fire, or further hardware damage.
✅ From the CompTIA A+ 220-1101 Official Study Guide, Objective 4.1 C Troubleshoot common hardware problems:
"Signs of electrical issues such as burning smells, smoke, or sparks require an immediate shutdown of the system and disconnection from any power source."
After ensuring safety, the technician should inspect the hardware for visible signs of damage:
✅ From the same Objective (4.1):
"Inspect for foreign objects, liquid damage, or burnt components. These can cause short circuits or thermal events that may damage the motherboard or other internal components."
These steps are standard practice in the industry to ensure safe and accurate diagnosis of faulty devices. Trying a different adapter (Option F) may make the problem worse, and contacting vendors (Option D) comes after initial safety and inspection.

Question #27
Which of the following best represents the purpose of NFC?
- A . Wired connections between several devices
- B . Short-distance wireless connections between two devices
- C . Wireless connections between multiple devices at once
- D . Direct connection of two computers for file sharing
Correct Answer: B
B
Explanation:
NFC (Near-Field Communication) is a subset of RFID technology designed for very short-range wireless communication, typically within a few centimeters. It is primarily used for contactless transactions, like mobile payments, and can also support peer-to-peer data exchanges. NFC operates at 13.56 MHz and enables devices to communicate when placed near each other.
