CompTIA 220-1101 Online Questions & Answers

• Question 771:

  Which of the following cables are the most likely to be implemented using a punch down block? (Select two).

  A. Telephone
  B. Fiber
  C. HDMI
  D. Ethernet
  E. Coaxial
  F. USB
  A. Telephone
  D. Ethernet

  ---

  Explanation

  Punch-down blocks are commonly used to terminate and manage cabling for telephone systems and Ethernet networks (e.g., Cat 5, Cat 6). These blocks allow for efficient organization and connection of wires.

  Why Not B (Fiber): Fiber cables use specialized connectors (e.g., SC, LC) and are not terminated with punch-down blocks.

  Why Not C (HDMI): HDMI cables are pre-terminated and not designed for punch- down termination.

  Why Not E (Coaxial): Coaxial cables use screw-type or compression connectors, not punch-down blocks.

  Why Not F (USB): USB cables are also pre-terminated with proprietary connectors.

• Question 773:

  A technician goes to a classroom to troubleshoot a projector that occasionally powers off. The technician recreates the issue and notices the projector will not power back on until approximately 15 minutes have passed. After 15 minutes of being powered on. the projector shuts off again. Which of the following should the technician perform NEXT to resolve the issue?

  A. Clean the filter.
  B. Adjust the standby timeout.
  C. Check the power cable connection.
  D. Replace the bulb.
  A. Clean the filter.

  ---

  Explanation

  Based on the given information, it seems that the projector is experiencing issues with overheating or a faulty power supply. The fact that it shuts off and cannot be turned back on until it has cooled down for 15 minutes suggests that the projector is overheating or there is a problem with the power supply. Therefore, the next logical step would be to clean the filter to ensure proper ventilation and airflow, as a dirty filter can cause overheating.

  B. PCIe
  C. NVMe
  D. SATA
  D. SATA

• Question 776:

  A technician is troubleshooting a laptop that has a blank LCD panel. The technician shines a flashlight into the LCD and sees a faint image. Which of the following BEST describes the issue?

  A. Defective inverter
  B. Incomplete video driver
  C. Incorrect input source
  D. Burned-out bulb
  A. Defective inverter

  ---

  Explanation

  an inverter is a device that converts DC power from the laptop's battery or AC adapter to AC power for the backlight of the LCD panel. If the inverter is defective, the backlight will not work and the LCD panel will appear blank or very dim. The user can still see a faint image if they shine a flashlight into the LCD because the LCD itself is still working.

• Question 777:

  A user states that when docking a laptop, network drives are lost. However, when working wirelessly, network drives are present. While troubleshooting, a technician does not see any recent infrastructure changes and thinks the laptop has a bad network card. The technician orders a new laptop for the user and closes the ticket documenting the new laptop. After receiving the new laptop, the user still cannot access network drives when docked.

  Which of the following steps did the technician skip?

  A. Document findings, actions, and outcomes.
  B. Establish a theory of probably cause.
  C. Test the theory to determine cause.
  D. Establish a plan of action.
  B. Establish a theory of probably cause.

  ---

  Explanation

  The technician failed to properly diagnose the issue by not establishing a theory of probable cause. Instead of investigating why the network drives were accessible wirelessly but not when docked, the technician assumed a faulty network card and ordered a new laptop. Proper troubleshooting involves developing a theory of what might be causing the problem, based on the symptoms and available information, and then testing that theory. In this case, the issue could have been related to docking station settings, network configurations, or hardware issues specific to the docking connection.

  References: This answer is grounded in standard troubleshooting methodologies, which emphasize the importance of logically deducing the most likely cause of a problem before proceeding with more drastic measures such as replacing hardware.

• Question 778:

  A technician is upgrading a desktop's storage with the fastest option available. The desktop's motherboard is equipped with SATA Ill, NVMe, and IDE. Which of the following should the technician choose for the best performance?

  A. PCIe SSD connected via NVMe interface
  B. 3.5in (8.9cm) 10,000rpm HDD connected via IDE interface
  C. M.2 SSD connected via SATA interface
  D. 2.5in (6.35cm) SSD connected via SATA interface
  A. PCIe SSD connected via NVMe interface

  ---

  Explanation

  The best option that the technician should choose for the best performance is A. PCIe SSD connected via NVMe interface. This option means that the technician should install a solid state drive (SSD) that uses the PCIe (Peripheral Component Interconnect Express) bus and the NVMe (Non-Volatile Memory Express) protocol to communicate with the motherboard. This option can offer the following advantages: Faster speed: PCIe SSDs can transfer data faster than SATA or IDE SSDs, as they use more lanes and have higher bandwidth. PCIe SSDs can reach speeds of up to 7,000 MB/s, while SATA SSDs are limited to 600 MB/s and IDE SSDs are even slower12. NVMe is a protocol that is designed specifically for SSDs and can optimize their performance by reducing latency and increasing parallelism3. Smaller size: PCIe SSDs can be smaller than SATA or IDE SSDs, as they do not require additional cables or connectors. PCIe SSDs can come in different form factors, such as M.2 or U.2, which can fit in different slots on the motherboard12. Higher reliability: PCIe SSDs can be more reliable than SATA or IDE SSDs, as they have less moving parts and are less prone to mechanical failures or data corruption. PCIe SSDs can also support features such as error correction and wear leveling, which can enhance their durability and lifespan12.

• Question 779:

  Which of the following is a scenario in which an F-type connector would be used?

  A. A technician is making a serial connection to a hardware device.
  B. An internet service provider is installing service for a client.
  C. A user is purchasing a charging cable for a laptop.
  D. An electrician is upgrading the service on an electrical panel.
  B. An internet service provider is installing service for a client.

  ---

  Explanation

  An F-type connector is a coaxial RF connector that is commonly used for cable television, satellite television, and cable modems. An internet service provider (ISP) may use an F-type connector to connect the coaxial cable from the wall outlet to the cable modem or the set-top box. The F-type connector has a threaded interface that provides a secure and reliable connection. The F-type connector can also support high-frequency signals up to several GHz, which can deliver high-speed internet and high-definition television. Other scenarios, such as making a serial connection to a hardware device, purchasing a charging cable for a laptop, or upgrading the service on an electrical panel, are not likely to use an F-type connector. A serial connection to a hardware device may use a DB-9 or a DB-25 connector, which are D-shaped connectors with pins. A charging cable for a laptop may use a USB or a barrel connector, which are flat or cylindrical connectors with contacts. An electrical panel may use a twist-lock or a pin-and-sleeve connector, which are round connectors with locking mechanisms.

• Question 780:

  A user added a heater underneath a desk, row an external monitor not working. A technician wanted the monitor gets power. Which of the following should the technician do next?

  A. Have the user unplug me heater
  B. Replace the monitor.
  C. Open the display settings on me computer
  D. Ensure a VGA cable is connected property
  D. Ensure a VGA cable is connected property

  ---

  Explanation

  The technician should ensure that a VGA cable is connected properly between the monitor and the computer. A VGA cable is a type of video cable that carries analog signals. If the cable is loose, damaged, or not plugged in correctly, it can cause the monitor to not display any image or show distorted colors. According to the CompTIA Core1 objectives, one of the common display issues is no image on screen. A troubleshooting guide for monitors also recommends checking the VGA cable connection as a possible solution for no signal or blank screen problems.
