CompTIA 220-1101 Online Questions & Answers

• Question 31:

  A technician is configuring the router for a small business network. Which of the following settings should the technician configure first?

  A. DHCP
  B. UPnP
  C. MAC filtering
  D. VPN
  A. DHCP

  ---

  Explanation

  When configuring a router for a small business, the first setting a technician should configure is DHCP (Dynamic Host Configuration Protocol). DHCP is responsible for automatically assigning IP addresses to devices on the network, which is essential for enabling communication within the network. Without DHCP, devices would not receive the necessary IP configurations to communicate effectively.

  DHCP: Configuring DHCP first ensures that all devices on the network receive their IP addresses automatically.

  Why the other options are incorrect:

  UPnP: UPnP (Universal Plug and Play) is used for simplifying device connectivity, but it is not a critical setting to configure first. MAC filtering: MAC filtering is a security feature that limits which devices can connect to the network based on their MAC addresses, but it should be set up after basic network configuration. VPN: VPN (Virtual Private Network) settings are for secure remote access, and should be configured after the essential network settings like DHCP are in place.

  This topic falls under the Networking domain of the CompTIA A+ Core 1 exam.

• Question 32:

  A user that works is sales is reporting that the output on each page printed from a laser has duplicate images. Which of the following should be performed FIRST to eliminate the ghost images?

  A. Change the paper weight setting.
  B. Replace the printer's fuser.
  C. Upgrade the printer firmware.
  D. Clean the toner drums and rollers
  D. Clean the toner drums and rollers

  ---

  Explanation

  If a laser printer is producing output with duplicate images (also known as ghost images), it could be due to an issue with the toner drums and rollers. The first step to eliminate the ghost images would be to clean the toner drums and rollers to remove any excess toner that may be causing the issue. Ghost images are a common issue in laser printers where an image or text from a previous page appears faintly on subsequent pages. The cause of this issue is usually due to toner residue on the drum or rollers, which can be removed by cleaning the toner drums and rollers.

• Question 33:

  Which of the following describes the main difference between T568Aand T568B cabling standards?

  A. The T568B data transfer rate is higher than T568A.
  B. The green and the orange cables are interchanged.
  C. T568A is used in blue cables, and T568B is used in green cables.
  D. The standards use different cable connectors.
  B. The green and the orange cables are interchanged.

  ---

  Explanation

  he main difference between T568A and T568B cabling standards is that the green and orange cables are interchanged12. T568A is designed for backward compatibility with older telephone wires, while T568B is designed for better signal isolation and noise protection for newer networking systems and products3. T568A is used in blue cables, and T568B is used in green cables1. The standards use the same cable connectors3.

• Question 34:

  A user is unable to use a drawing stylus on a smartphone. The smartphone did not originally come with a stylus. Which of the following is the most likely cause of this issue?

  A. The phone needs to be updated to the latest OS.
  B. The drawing stylus only works with a special digitizer.
  C. The stylus must be re-paired to this new device.
  D. The phone's screen only supports resistive styluses.
  B. The drawing stylus only works with a special digitizer.

  ---

  Explanation

  A digitizer is a device that converts analog signals, such as touch or pressure, into digital signals that can be processed by a computer. A digitizer is usually embedded in the screen of a smartphone or tablet, and it works with a compatible stylus to enable drawing and writing on the screen1. There are different types of digitizers and styluses, such as capacitive, resistive, active, and passive. Capacitive digitizers and styluses work by detecting changes in the electric field on the screen when the stylus touches it. Resistive digitizers and styluses work by detecting changes in the resistance on the screen when the stylus presses it. Active digitizers and styluses work by using an electromagnetic field to communicate between the stylus and the screen. Passive digitizers and styluses work by using a special material on the tip of the stylus that mimics the human finger2. Not all digitizers and styluses are compatible with each other. For example, an active stylus will not work with a capacitive or resistive digitizer, and vice versa. A passive stylus will work with any digitizer, but it will not have any advanced features, such as pressure sensitivity or tilt control2.

  F. Bluetooth

  ---

  Explanation

  The appropriate connection types for connecting an external keyboard to an Android tablet are USB-C and Bluetooth.

• Question 36:

  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.

• Question 37:

  A technician recently set up a VM on a client PC to create and test software. The technician has since discovered the virtual environment has no external connectivity. The technician verifies the host has an Internet connection. Which of the following should the technician do NEXT to resolve the issue?

  A. Configure a static IP for the VM and enable bridged networking.
  B. Create a host record with the IP address and hostname of the VM and store it on the host.
  C. Configure a dynamic IP for the host and the VM.
  D. Configure a dynamic IP for the host and disable any host intrusion detection software.
  A. Configure a static IP for the VM and enable bridged networking.

• Question 39:

  A company in a large building uses a wireless network for its workstations. After a new company moves into the building on the floor below, the old company's wireless network begins experiencing connectivity Issues. Which of the following is the most likely cause?

  A. External interference
  B. Port flapping
  C. High latency
  D. Limited connectivity
  A. External interference

  ---

  Explanation

  The most likely cause of the wireless network connectivity issues is A. External interference. External interference is any signal or noise that disrupts or degrades the quality of a wireless network. External interference can come from various sources, such as other wireless networks, cordless phones, microwaves, Bluetooth devices, or electrical appliances. External interference can affect the wireless network performance, reliability, and security, by causing issues such as signal loss, packet drops, latency, or interference. In this scenario, a company in a large building uses a wireless network for its workstations. After a new company moves into the building on the floor below, the old company's wireless network begins experiencing connectivity issues. This could indicate that the new company's wireless network is using the same or overlapping frequency channel as the old company's wireless network, and creating external interference. Wireless networks use radio frequency channels to transmit and receive data, and each channel has a certain bandwidth and range. If two or more wireless networks use the same or overlapping channel, they may interfere with each other and cause congestion or collision. To resolve this issue, the old company's network technician should change the wireless network channel to a different one that is less crowded or more compatible with the wireless network standard. The technician should also check the wireless network settings and features, such as SSID (Service Set Identifier), encryption, authentication, or power level, and adjust them if necessary. The technician should also scan the wireless environment and identify the sources and levels of external interference, and try to avoid or minimize them if possible. For more information about external interference and how to prevent or reduce it, you can refer to the following web search results: [What Is Wireless Interference?], [How to Find the Best WiFi Channel for Your Router], [How to Reduce Wireless Interference].
