CompTIA 220-1201 Online Questions & Answers

• Question 211:

  A company wants to enable access to corporate email on smartphones. Employees must install software that separates corporate and personal data.

  Which should the company implement?

  A. Encryption
  B. Network access control
  C. Mobile device management
  D. Endpoint protection
  C. Mobile device management

  ---

  Explanation

  The requirement to separate corporate and personal data on employee smartphones is a core function of Mobile Device Management (MDM). CompTIA A+ describes MDM as an enterprise toolset used to enforce security policies, manage applications, configure email profiles, and separate work-related data from personal user data. This separation is typically achieved through features such as containerization , where corporate data is stored in a protected, encrypted workspace that is isolated from the personal side of the device.

  This ensures security, prevents data leakage, and enables IT administrators to remotely wipe corporate data without affecting the user's personal information. MDM solutions are widely used in BYOD (Bring Your Own Device) environments and corporate-issued devices.

  Encryption (A) protects data but does not create separation. Network access control (B) restricts network access but does not manage mobile apps or data separation. Endpoint protection (D) refers to antivirus / antimalware, not data partitioning.

  Thus, Mobile Device Management (MDM) is the correct solution.

• Question 212:

  A technician needs to build a computer that can tolerate high CPU utilization and graphics usage.

  Which of the following components provides the best benefit for the computer?

  A. Liquid cooling
  B. Advanced RISC
  C. x86 processor
  D. Hardware security module
  A. Liquid cooling

  ---

  Explanation

  The correct answer is A. Liquid cooling.

  High CPU utilization and intensive graphics workloads generate significant heat. According to CompTIA A+ Core 1 220-1201 hardware objectives, ensuring proper thermal management is crucial for system stability and performance.

  Liquid cooling provides more efficient heat dissipation than standard air cooling, allowing CPUs and GPUs to maintain optimal performance under heavy load and preventing thermal throttling. This is especially beneficial in gaming, video editing, rendering, or scientific computation workloads.

  Why the other options are incorrect:

  B. Advanced RISC: Refers to a type of processor architecture optimized for efficiency and specific instruction sets but does not directly address heat or cooling in high-utilization systems.

  C. x86 processor: This is a general processor architecture; while important, it does not mitigate heat or improve cooling under heavy CPU/ GPU usage.

  D. Hardware security module: Focused on cryptographic operations and secure key storage, unrelated to CPU or GPU thermal management.

  A. 21
  B. 53
  C. 68
  D. 389
  A. 21

  ---

  Explanation

  Port 21 is used by FTP (File Transfer Protocol) for file transfers. Port 53 is for DNS, port 68 is for DHCP, and port 389 is for LDAP. Understanding standard network ports is essential in CompTIA A+ Core 1 objectives, especially in networking and troubleshooting scenarios.

• Question 215:

  An end user wants to share their cellular internet connection with their laptop.

  Which of the following technologies should they use?

  A. Hotspot
  B. Bluetooth
  C. NFC
  D. Ethernet
  A. Hotspot

  ---

  Explanation

  To share a phone's cellular data connection with a laptop, the user should use a hotspot, also known as mobile hotspot or Wi-Fi tethering. In CompTIA A+ Core 1 terms, this feature allows a smartphone to act like a small wireless router: it takes the phone's mobile data (4G/5G) connection and rebroadcasts it over Wi-Fi so another device (the laptop) can join the wireless network using an SSID and password. This is the most common and straightforward method because laptops universally support Wi-Fi and the connection typically provides better throughput than other tethering methods. Hotspot/tethering settings also commonly allow configuration of security (WPA2/WPA3) and can limit connected devices to reduce unauthorized access and manage data usage.

  Bluetooth (option B) can support tethering on some devices, but it is slower, more limited, and not the primary expected answer when the goal is simply sharing cellular internet with a laptop. NFC (option C) is mainly used for close-range pairing or payments and does not provide an internet sharing link by itself. Ethernet (option D) would require wired adapters and is not the standard method for cellular sharing.

  Therefore, Hotspot is the best answer.

• Question 216:

  A field technician has been dispatched to a site with an internet outage. Upon arriving, the technician discovers that the POTS lines are not working as well.

  Which of the following technologies is the site MOST likely using?

  A. Fiber
  B. Cable
  C. DSL
  D. Satellite
  C. DSL

  ---

  Explanation

  DSL (Digital Subscriber Line) uses POTS (Plain Old Telephone Service) lines to provide high-speed internet access. If the POTS lines are not working, it could cause an internet outage for DSL customers. Fiber and cable internet typically use different types of infrastructure, while satellite internet is not reliant on POTS lines.

• Question 218:

  Which of the following is a characteristic to consider when selecting a satellite internet connection?

  A. Necessary proximity to urban infrastructure
  B. eSIM requirement
  C. Line of sight to nearby tower
  D. Increased latency
  D. Increased latency

  ---

  Explanation

  In the CompTIA A+ Core 1 (220-1201) networking concepts, satellite internet is commonly associated with higher (increased) latency compared with terrestrial options like cable, fiber, or DSL. Latency is the delay between sending data and receiving a response. With satellite, signals must travel from the user's dish up to a satellite and then back down to a ground station (and return again for responses). That long travel distance adds noticeable delay, which can affect real-time activities such as VoIP, video conferencing, and online gaming. Even though newer low-earth-orbit (LEO) systems can reduce latency compared with older geostationary systems, satellite service is still generally discussed in A+ as having higher latency characteristics to consider.

  The other options do not best fit satellite internet. Proximity to urban infrastructure (A) is more relevant to cable/fiber availability. An eSIM requirement (B) relates to cellular/mobile service, not satellite broadband. Line of sight to a nearby tower (C) describes cellular or fixed wireless services that depend on tower connectivity; satellite instead needs a clear view of the sky toward the satellite (not a nearby tower). Therefore, increased latency is the best characteristic to consider.

• Question 219:

  A technician is upgrading a faulty motherboard that was ordered by an end user for an old, high-end desktop computer. However, the technician is unable to install the CPU into the socket. Upon closer inspection, the technician notices the pins on the CPU do not line up with the socket.

  Which of the following would be the best course of action for the technician to take NEXT?

  A. Try to set as many pins as possible.
  B. Install an adaptor to create a universal socket.
  C. Verify the socket type and manufacturer.
  D. Find a compatible motherboard for the CPU.
  C. Verify the socket type and manufacturer.

  ---

  Explanation

  In this situation, the best course of action for the technician to take NEXT would be C. Verify the socket type and manufacturer. If the pins on the CPU do not line up with the socket on the motherboard, it is likely that there is a compatibility issue between the two components. The technician should verify that the socket type and manufacturer of the motherboard match those of the CPU to ensure that they are compatible.

• Question 220:

  A user attempts to print diagrams on 11x17 inch (28x43 cm) paper. The correct paper is loaded, but the printer keeps prompting for paper. Another identical printer prints successfully.

  What is the MOST likely cause?

  A. Tray settings
  B. Incorrect driver
  C. Connectivity issues
  D. Insufficient permissions
  A. Tray settings

  ---

  Explanation

  When a printer refuses to use paper that is physically present in the tray, CompTIA A+ identifies tray configuration settings as the most likely cause. Printers require a match between tray settings (paper size, paper type, orientation) and the incoming print job's specifications. If the tray is incorrectly configured--such as being set to Letter (8.5?1 in) or A4--then the printer will keep prompting for the correct paper even though 11?7 paper is loaded.

  The fact that the technician successfully prints the same diagram on another identical printer proves that the driver, print job format, and user permissions are correct. This isolates the issue to the local printer's configuration. Incorrect drivers (B) would affect printing on both printers. Connectivity issues (C) would prevent printing entirely, not cause paper prompts. Permissions (D) do not affect paper-size recognition.

  Therefore, the most likely cause is improper tray settings on the user's printer.
