CompTIA 220-1201 Online Questions & Answers

• Question 111:

  A support technician receives a call stating that a user has added a device to the network. The user used the same configurations from another workstation.

  When both workstations are turned on, neither can access the network reliably.

  Which of the following is the most likely cause of the issue?

  A. The new computer has a duplicate IP address.
  B. The DNS server is registering both hostnames.
  C. The network cable was improperly terminated.
  D. The security on the switchport needs to be reset.
  A. The new computer has a duplicate IP address.

  ---

  Explanation

  If two devices have the same static IP address, an IP conflict occurs. This results in both devices being intermittently disconnected or unable to communicate on the network. It's a common mistake when copying configurations manually.

  Option B:DNS conflicts wouldn't cause total disconnection -- and wouldn't occur just from copying IP settings.

  Option C:A cable issue would only affect one workstation.

  Option D:Switchport security issues wouldn't affect both machines simultaneously unless port security was configured very specifically.

  Explanation

  The degraded status on Server 2 indicates a RAID-5 issue, typically due to a failed or failing drive. In RAID-5 configurations, when one drive fails, the system can still operate but with reduced performance as parity data is used to rebuild missing data on-the-fly.

  Recommended Replacement Drive:

  To minimize performance degradation, the replacement drive should be:

  SAS HDD with the same specifications (64KB stripe size, no read-ahead, and write-back policy).

  Matching the configuration exactly ensures seamless integration and optimizes recovery speed in the RAID-5 array.

  In RAID-5, degraded performance is expected when one drive fails, as parity data needs to rebuild missing information during each read/write process. Replacing the failed drive restores the RAID array to optimal status, reducing the load on existing drives and returning the system to normal read/write performance. The write-back policy and disabled disk cache settings are designed to reduce latency and increase efficiency, essential for handling real-time applications.

  A user reports poor performance on the application server.

• Question 114:

  A user is trying to present a video in a conference room. The video appears when the user connects the computer to the TV display with an HDMI cable. However, there is no sound coming through. The computer and TV volumes are at 50%.

  Which of the following should the user perform next?

  A. Adjust the volume settings
  B. Swap the HDMI cable
  C. Reinsert the HDMI cable
  D. Verify the audio output assignment
  D. Verify the audio output assignment

  ---

  Explanation

  The correct answer is D. Verify the audio output assignment.

  According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Troubleshooting:

  HDMI carries both video and audio signals. If video displays correctly but audio is not heard, it is often because the computer is still outputting sound to its internal speakers rather than the HDMI-connected device.

  The user should check the audio output settings in the operating system and ensure the HDMI device (TV or projector) is selected as the audio output device.

  Why the other options are incorrect:

  A. Adjust the volume settings: Volumes are already at 50%, so adjusting them will not solve the problem if the audio output is assigned incorrectly.

  B. Swap the HDMI cable: The video is working fine, so the cable is likely functional.

  C.

  Reinsert the HDMI cable: Unlikely to resolve audio assignment issues if the connection is already working for video.

• Question 115:

  Which of the following best describes metered utilization for cloud computing?

  A. Cloud resources are billed to clients based on usage.
  B. Cloud resources are shared with other companies conducting similar business.
  C. Cloud resources are available at a fixed amount for a fixed price.
  D. Cloud resources are located in the on-site data center.
  A. Cloud resources are billed to clients based on usage.

  ---

  Explanation

  Metered utilization for cloud computing is a pricing model where cloud service providers charge clients based on the amount of resources they consume, such as network bandwidth, storage space, CPU cycles, or memory. This allows clients to pay only for what they use, rather than a fixed amount or a subscription fee. Metered utilization can also enable clients to scale their cloud resources up or down according to their needs and demand.

  ---

  Explanation

  A punchdown tool is essential for connecting telephone wires to patch panels, keystone modules, and punchdown blocks, making it a critical tool for installing plain old telephone service (POTS) lines. A toner probe, on the other hand, is used for tracing and identifying specific wires within a bundle, facilitating the correct attachment of telephone lines to their respective terminals. These tools are fundamental for ensuring proper and efficient installation of POTS lines in a client's environment.

• Question 117:

  A technician is troubleshooting a desktop PC that is plugged into a UPS. The PC loses the system date/time after every power outage.

  Which of the following should the technician do to resolve the issue? (Select two).

  A. Run a BIOS update.
  B. Swap out the RAM.
  C. Disable NTP in the OS.
  D. Repair the backup power source.
  E. Replace the CMOS battery
  F. Install a surge protector.
  D. Repair the backup power source.
  E. Replace the CMOS battery

  ---

  Explanation

  The system date/time is maintained by the CMOS battery when the PC is powered off. If this battery fails, time resets will occur. Additionally, since the system is connected to a UPS, ensuring the UPS is functioning correctly (i.e., the backup power source) is essential.

• Question 118:

  Which of the following wireless frequency ranges involves the use of channels 1, 6, and 11?

  A. 2.4GHz
  B. 5GHz
  C. 6GHz
  D. 60GHz
  A. 2.4GHz

  ---

  Explanation

  In Wi-Fi, the 2.4GHz band contains 14 total channels (depending on region), but only channels 1, 6, and 11 are considered non-overlapping in most countries. CompTIA A+ highlights the importance of selecting these channels to minimize interference, especially in environments with multiple wireless networks or access points.

  The 2.4GHz band is narrower than 5GHz, causing adjacent channels to overlap significantly. Using channels 1, 6, and 11 prevents overlap and reduces signal interference, improving performance and stability.

  5GHz (B) has many non-overlapping channels and does not use the 1/6/11 scheme. The 6GHz band (C) is part of Wi-Fi 6E and uses entirely different channel planning. The 60GHz band (D) supports short-range high-speed connections like WiGig, not traditional Wi-Fi channels.

  Therefore, the 2.4GHz band is the correct answer.

• Question 119:

  A customer brings a phone top a repair shop because it is experiencing extreme slowness and applications are crashing. A technician attempts to install a diagnostic application. but the installation fails.

  Which of the following should the technician do FIRST to troubleshoot the issue?

  A. Check the storage space.
  B. Inspect the screen for damage.
  C. Install the latest updates.
  D. Recalibrate the digitizer.
  A. Check the storage space.

  ---

  Explanation

  One of the possible causes of extreme slowness and application crashes on a phone is low or insufficient storage space. This can affect the performance and functionality of the phone, as well as prevent new applications from being installed or updated. The technician should check the storage space on the phone and see if there is enough free space available for the diagnostic application and other operations. The technician should also advise the customer to delete or move any unnecessary or unused files, apps, or data from the phone to free up some space.

• Question 120:

  A user prints a spreadsheet in duplex mode. The spreadsheet is difficult to read because some of the columns spill onto the second side of the page.

  Which of the following should the user do to prevent the issue but still print on both sides of the page?

  A. Turn off duplex printing.
  B. Try a smaller font size in the spreadsheet.
  C. Change the page orientation.
  D. Use a different print driver.
  C. Change the page orientation.

  ---

  Explanation

  Changing the page orientation(e.g., fromportrait to landscape) allows wider columns to fit on one side of the page. This maintains readability while continuing to use duplex printing.

  Option A:Disabling duplex defeats the goal of printing on both sides.

  Option B:May help, but could make the document harder to read if the font is too small.

  Option D:Unlikely to resolve formatting issues related to layout and dimensions.
