  F. Try an alternate AC adapter.
  A. Turn it off and disconnect all power sources.
  C. Check for foreign objects, liquid spills, and internal damage.

  ---

  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 -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 295:

  A user joins a conference call with a Bluetooth headset.

  Which of the following has the user created?

  A. MAN
  B. PAN
  C. SAN
  D. WAN
  B. PAN

  ---

  Explanation

  A PAN is a network established between devices in close proximity, such as between a smartphone and a Bluetooth headset.

  Bluetooth technology is specifically designed for short-range communication, making it a type of PAN.

  Incorrect Options:

  Option A:

  MAN (Metropolitan Area Network): A MAN covers a city or metropolitan area and is not relevant to Bluetooth connections.

  Option C:

  SAN (Storage Area Network): A SAN is used for large-scale data storage, unrelated to Bluetooth connections.

  Option D:

  WAN (Wide Area Network): A WAN spans large geographical areas (e.g., the internet) and is not relevant to this scenario.

  Key Takeaway: Bluetooth connections, such as those between a headset and a device, create a Personal Area Network (PAN).

• Question 296:

  Which of the following storage options would a technician most likely recommend to have large amounts of affordable capacity without concern for read times on a desktop computer?

  A. 750GB NVMe M.2 SSD
  B. 2x 1TB PCIe SSD in RAID 1
  C. 2TB SATA 3.5" 5,400rpm HDD
  D. 4TB SAS 2.5" 15,000rpm HDD
  C. 2TB SATA 3.5" 5,400rpm HDD

  ---

  Explanation

  If performance is not a primary concern and the user requires large, cost-effective storage, a 2TB 5400rpm SATA HDD is ideal. It offers high capacity at a lower price point than SSDs and faster HDDs.

  Option A:NVMe drives offer exceptional speed but are significantly more expensive per GB and not necessary when read/write speed is not a concern.

  Option B:RAID 1 improves redundancy but cuts usable capacity in half and uses expensive SSDs.

  Option D:SAS drives are fast and reliable but are enterprise-grade and expensive -- overkill for desktop use.

• Question 297:

  Which of the following supports the most devices due to its status as a legacy technology?

  A. 2.4GHz
  B. 5GHz
  C. 6GHz
  D. NFC
  A. 2.4GHz

  ---

  Explanation

  The correct answer is A. 2.4GHz.

  In the CompTIA A+ Core 1 220-1201 networking objectives, wireless networking technologies include frequency bands such as 2.4GHz, 5GHz, and 6GHz, along with related concepts like channels, regulations, channel selection, Bluetooth, 802.11 standards, NFC, and RFID.

  The 2.4GHz band supports the most devices because it is the oldest and most widely adopted Wi-Fi frequency listed. Many legacy devices, including older laptops, printers, IoT devices, smart home devices, and wireless peripherals, still rely on 2.4GHz. It also has better range and wall penetration than higher-frequency bands, although it is usually more crowded and slower.

  Why the other options are incorrect:

  B. 5GHz 5GHz is newer than 2.4GHz and generally provides faster speeds with less interference, but it does not support as many older legacy devices.

  C. 6GHz 6GHz is the newest Wi-Fi frequency option used with newer Wi-Fi standards, so it has the least legacy device support among the Wi-Fi frequency choices.

  D. NFC NFC is a short-range communication technology, not a Wi-Fi frequency band. It is used for close-proximity functions such as tap-to-pay, pairing, and access cards, so it is not the best answer. Final Answer:

  A. 2.4GHz

• Question 298:

  Which of the following can carry data and electricity to network devices? (Select two).

  A. Router
  B. Injector
  C. Cable modem
  D. Access point
  E. PoE
  F. Unmanaged switch
  B. Injector
  E. PoE

  ---

  Explanation

  PoE (Power over Ethernet) allows both data and electrical power to be delivered over the same Ethernet cable. A PoE injector adds power to Ethernet cables for devices that need it.

  From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 -Networking hardware:

  "Power over Ethernet (PoE) technology and PoE injectors enable both power and data transmission to compatible network devices like access points and IP cameras."
