  Which of the following tools is best to track where an Ethernet cable is patched?

  A. Crimper
  B. Punchdown tool
  C. Cable stripper
  D. Toner probe
  D. Toner probe

  ---

  Explanation

  A toner probe (also known as a tone generator and probe) is the best tool for tracing and identifying cables in a patch panel or wall jack. The tone generator sends a signal through the wire, and the probe helps locate the cable by detecting the tone.

  Option A (Crimper):Used to attach connectors (e.g., RJ-45), not for tracing cables.

  Option B (Punchdown tool):Used to terminate cables into patch panels or keystone jacks.

  Option C (Cable stripper):Used to remove insulation, not to trace cables.

• Question 175:

  When a user powers on a computer, the fans start, but the machine does not POST.

  Which of the following is the first step a technician should take to troubleshoot this issue?

  A. Test the power supply.
  B. Modify the BIOS settings.
  C. Replace the motherboard.
  D. Check the PCIe cards.
  A. Test the power supply.

  ---

  Explanation

  Testing the power supply first ensures that the correct voltage is reaching all components, which is a common cause of boot issues. Modifying BIOS settings is not possible without a POST. Checking PCIe cards or replacing the motherboard are secondary steps if the power supply is functional. CompTIA A+ Core 1 objectives cover power supply testing as an essential troubleshooting step in system startup issues.

• Question 176:

  Which of the following drive interfaces is typically used in server systems but not in home computers?

  A. NVMe
  B. SAS
  C. SATA
  D. PCIe
  B. SAS

  ---

  Explanation

  SAS (Serial Attached SCSI) is a high-performance drive interface commonly found in enterprise environments and servers due to its reliability and speed. While SATA is more common in consumer systems, SAS is specifically designed for mission-critical applications, offering features like full-duplex operation and compatibility with SATA drives.

• Question 178:

  When a customer tries to connect a projector to a laptop in a conference room, the customer is only able to see part of the laptop ' s screen projected onto the wall.

  Which of the following should a technician do first to troubleshoot this issue?

  A. Extend the desktop
  B. Change the resolution
  C. Mirror the desktop
  D. Switch the input source
  B. Change the resolution

  ---

  Explanation

  The correct answer is B. Change the resolution.

  According to the CompTIA A+ Core 1 220-1201 objectives, troubleshooting display issues involves checking the display settings, including resolution, scaling, and orientation. When a projector is only showing part of a laptop screen:

  The most common cause is that the laptop's output resolution does not match the projector ' s native resolution. If the laptop is set to a resolution larger than what the projector supports, only a portion of the screen is visible.

  The technician should first adjust the laptop ' s resolution to match the projector's native resolution before attempting other options like extending or mirroring the desktop.

  Why the other options are incorrect:

  A. Extend the desktop: This is only used if the user wants to have two separate screens (dual monitors), not to fix partial display issues.

  C. Mirror the desktop: Mirroring duplicates the laptop display but does not solve issues caused by resolution mismatch.

  D. Switch the input source: Necessary only if the projector is on the wrong input, but the problem here is a partial display, not no display.

• Question 179:

  A user is trying to play a DVD on a projector. The user can hear the audio; however, the projector is showing an error message that states:

  HDMI Blocked due to Copy Protection

  Which of the following is the MOST likely cause of the error?

  A. The HDMI cannot carry the signal from the DVD to the projector.
  B. The user needs to switch from HDMI to a cable standard such as DisplayPort.
  C. The projector does not support the necessary HDCP protocol.
  D. The user needs to enable cony-protected sources in the projector's settings.
  C. The projector does not support the necessary HDCP protocol.

  Explanation

  The Official CompTIA A+ Core 1 and Core 2 Student Guide (Exams 220- 1001 and 220-1002) | 193 Protected content. If you encounter an error that indicates unauthorized content or an HDCP error: DVI, HDMI, DisplayPort, and Thunderbolt all provide support for the Digital Rights Management (DRM) mechanism High- bandwidth Digital Content Protection (HDCP). HDCP allows a content source (such as a Blu-ray disc) to disable itself if the display adapter and monitor and/or speaker system do not support HDCP and fail to authenticate themselves with the playback source. There have been various iterations of HDCP (at time of writing the current version is 2.2) and backward-compatibility can be problematic as authentication may fail between devices that support different versions of the standard.

• Question 180:

  A customer reports that internet browsing on their smartphone is fast at the beginning of the month but significantly slows down toward the end of the month. A technician examines the smartphone and finds multiple free cloud backup services running with several gigabytes of personal data spread across each.

  Data availability is important to the customer.

  Which of the following is the best way to resolve the customer ' s issue?

  A. Disabling all cloud backup services except one
  B. Installing an additional SD card for photos and videos
  C. Expanding the cache storage to consolidate data
  D. Configuring data synchronization only over Wi-Fi connections
  D. Configuring data synchronization only over Wi-Fi connections

  ---

  Explanation

  The described behavior indicates that the customer is likely exceeding their mobile data allowance each month. Multiple cloud backup services continuously synchronizing gigabytes of data consume large amounts of cellular bandwidth, which can trigger data throttling by the mobile carrier near the end of the billing cycle. This results in noticeably slower browsing speeds. Since data availability is important, disabling backup services entirely is not the best option. Installing an SD card increases local storage but does not reduce cellular data usage. Expanding cache storage does not address network bandwidth consumption or carrier throttling. Configuring data synchronization to occur only over Wi-Fi ensures that backups continue uninterrupted when the device is connected to a wireless network, while preventing excessive cellular data usage. This preserves data availability and eliminates unnecessary mobile data consumption, restoring consistent browsing performance throughout the month.

  CompTIA Core 1 (220-1201) mobile device troubleshooting objectives emphasize managing background services, synchronization settings, and data usage to resolve performance and connectivity issues on smartphones.
