CompTIA 220-1201 Online Questions & Answers

• Question 421:

  A technician needs to select PC components with a minimal number of visible internal cables.

  Which of the following should the technician use?

  A. SATA drive connections
  B. Liquid cooling Modular
  C. power supply Wireless
  D. NIC
  C. power supply Wireless

  ---

  Explanation

  Amodular power supplyallows a technician toconnect only the power cables that are needed, reducing clutter and improving airflow. This is ideal when aiming for a clean build withminimal visible internal cables.

  Option A (SATA drive connections):Still require both power and data cables, adding to cable count.

  Option B (Liquid cooling):May reduce some bulk from large air coolers, but adds tubing and still needs cabling.

  Option D (Wireless NIC):Adds wireless capability but has no relation to internal cabling cleanliness.

• Question 422:

  A company provides cell phones to employees who travel internationally. An employee brings their phone to the help desk so the necessary equipment can be installed. However, the technician cannot install any new hardware on the phone.

  Which of the following will the technician require so the phone can connect to a different provider?

  A. USB-C
  B. SD card
  C. eSIM
  D. MDM
  C. eSIM

  ---

  Explanation

  An eSIM (embedded SIM) allows users to change carriers and provision new cellular service without installing any physical hardware. It is managed via software and is ideal for international travelers who need to switch providers quickly.

  From the CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 -Install and configure mobile device network connectivity:

  "eSIMs provide carrier flexibility by enabling remote provisioning and profile switching, making it possible to connect to different networks without a physical SIM card."

• Question 423:

  A company wants to use cloud services with the requirement that data will reside on physical hardware that will not be shared with other companies.

  Which of the following meets this requirement?

  A. Dedicated resources
  B. Elasticity
  C. Hybrid cloud
  D. SaaS
  A. Dedicated resources

• Question 424:

  A customer ' s laptop is no longer charging when plugged in to the docking station. A technician observes that none of the devices plugged in to the dock appear to be functioning. The technician verifies that the dock has power, the laptop ports are not damaged, and the BIOS updates are current, but the issue persists.

  Which of the following should the technician do next?

  A. Switch the power supply.
  B. Replace the dock with a new one.
  C. Reinstall the OS on the laptop.
  D. Roll back the BIOS updates.
  B. Replace the dock with a new one.

  ---

  Explanation

  When both charging and dock-connected peripherals fail at the same time, the problem is most likely with the dock itself or its internal controller circuitry rather than the laptop's operating system or a single peripheral device. The technician has already verified key prerequisites: the dock has power, the laptop ports show no physical damage, and system firmware (BIOS/UEFI) is current. Those checks reduce the likelihood of a simple firmware incompatibility or a damaged laptop connector.

  In CompTIA A+ troubleshooting methodology, the next step is to substitute with a known-good component to isolate the fault quickly. Replacing (or testing with) another dock confirms whether the original docking station has failed. If the replacement dock restores charging and peripherals immediately, the root cause is confirmed without unnecessary invasive actions.

  Switching the power supply could be a valid step if power was questionable, but the prompt states the dock already has power and still provides no function-pointing to dock failure. Reinstalling the OS is excessive and unlikely because charging through a dock is not primarily OS-dependent. Rolling back BIOS updates is also not indicated because the issue persists despite current firmware and there is no evidence the BIOS update caused it.

• Question 425:

  Which of the following services allows a networked host to automatically assign IP addresses to devices on a network?

  A. DNS
  B. DHCP
  C. SMTP
  D. SNMP
  B. DHCP

  ---

  Explanation

  DHCP Dynamic Host Configuration Protocol is the service that automatically assigns IP addresses and other essential network settings to devices when they join a network. Instead of manually configuring each device with an IP address, subnet mask, default gateway, and DNS servers, a DHCP server provides these settings dynamically from a defined address pool. This reduces configuration errors, prevents IP conflicts, and makes network administration easier-especially in environments with many devices or frequent changes. In the DHCP process, a client broadcasts a request, the DHCP server offers an address, the client requests that offered address, and the server acknowledges it, granting the device a lease for a specific period. The lease can be renewed, and administrators can also configure reservations to always give the same IP to a particular device based on its MAC address.

  DNS is used for resolving hostnames to IP addresses, not assigning them. SMTP is for sending email between mail servers and clients. SNMP is used for monitoring and managing network devices. Therefore, DHCP is the correct service for automatically assigning IP addresses.

• Question 426:

  Which of the following is an advantage of using the 2.4 GHz wireless frequency?

  A. Communication between devices without external power
  B. Security for connections in close proximity
  C. Minimized structural interference
  D. Increased channel options
  C. Minimized structural interference

  ---

  Explanation

  Comprehensive and Detailed Explanation From Exact Extract (Aligned With CompTIA A+ 220-1201 Study Guide)

  The CompTIA A+ wireless networking section describes key differences between 2.4 GHz and 5 GHz Wi-Fi frequencies.

  2.4 GHz provides:

  Better range

  Better wall penetration

  Better performance through structures and obstacles

  This means less interference from physical structures , which is the primary advantage of 2.4 GHz over 5 GHz.

  This maps directly to:

  # C. Minimized structural interference

  Why the other options are incorrect

  A. Communication without external power Not related to Wi-Fi frequencies.

  B. Security for close-proximity connections No Wi-Fi frequency provides inherent security advantages.

  D. Increased channel options 5 GHz has more channels, not 2.4 GHz.

• Question 427:

  A company needs to print several copies of a multipage document with the least consumption of resources possible.

  Which of the following settings will best accomplish this task?

  A. Duplex
  B. Orientation
  C. Tray settings
  D. Quality
  A. Duplex

  ---

  Explanation

  Using the duplex setting allows the printer to print on both sides of the paper, effectively reducing paper usage by half for multipage documents. This option is ideal for conserving resources in a high-volume environment. According to the CompTIA A+ Core 1 objectives, duplexing is a standard function in multifunction devices, helping reduce paper usage and optimize printing efficiency. This method not only lowers costs but is also environmentally beneficial. Other options like "Orientation" only affect page layout, "Tray settings" adjust paper source without conserving resources, and "Quality" affects print resolution but not resource consumption.

• Question 428:

  An office manager wants to block all outbound internet traffic but continue to enable all inbound traffic.

  Which of the following should a technician configure to achieve this goal?

  A. MAC filtering
  B. Network interface card
  C. Firewall
  D. Switch
  C. Firewall

  ---

  Explanation

  Comprehensive and Detailed Explanation From Exact Extract:

  A firewall allows for detailed traffic control, including blocking outbound connections while allowing inbound ones. This is contrary to typical security setups, but it can be configured via advanced firewall rules.
