• Question 481:

  Which of the following types of RAM would most likely be used in a server?

  A. SODIMM
  B. ECC
  C. Unbuffered
  D. DDR3
  B. ECC

• Question 482:

  Which of the following display characteristics would be most important to ensure screen images appear the same as printed output?

  A. Color gamut
  B. Pixel density
  C. Refresh rate
  D. Resolution
  A. Color gamut

  ---

  Explanation

  Color gamut refers to the range of colors a display can accurately reproduce. For tasks like graphic design or photo editing, ensuring the screen's colors match the printed output is critical. Monitors with wide and accurate color gamuts (e.g., Adobe RGB) are preferred for these applications.

  Option B (Pixel density): Incorrect. Pixel density affects image sharpness, not color accuracy.

  Option C (Refresh rate): Incorrect. Refresh rate impacts motion smoothness but is unrelated to color matching.

  Option D (Resolution): Incorrect. Resolution determines clarity and detail but does not influence color accuracy.

• Question 483:

  Which of the following is used to verify if a NIC port can send and receive data?

  A. Loopback plug
  B. Toner probe
  C. Cable tester
  D. Network tap
  A. Loopback plug

  ---

  Explanation

  A loopback plug is used to test the functionality of network interface card (NIC) ports to ensure they can send and receive data. It is a diagnostic tool that loops back the signal to the device, allowing verification of the network port's operation.

  This aligns with CompTIA Core 1 objectives related to troubleshooting wired and wireless networks and verifying network connectivity.

• Question 484:

  A user is having issues when charging a device with a Lightning cable. The cable is not recognized when it is plugged into the device. This issue is usually resolved by flipping the cable over. This issue does not occur with other devices of the same type.

  Which of the following would most likely cause the issue?

  A. The device needs to be restarted.
  B. The battery may be swelling and needs inspection.
  C. The cable is failing and needs to be replaced
  D. The charging port is dirty or damaged
  D. The charging port is dirty or damaged

  ---

  Explanation

  When a Lightning cable works only when flipped a certain way or doesn't function consistently, it is typically due to debris or damage in the charging port. Cleaning the port or inspecting it for wear resolves the issue.

• Question 485:

  Which of the following best describes a Type 2 hypervisor?

  A. It works as a firewall to control network traffic.
  B. It interacts directly with the underlying hardware.
  C. It runs on a host operating system.
  D. It brings higher CPU capabilities to virtual machines.
  C. It runs on a host operating system.

  ---

  Explanation

  CompTIA A+ divides hypervisors into two main categories: Type 1 (bare-metal) and Type 2 (hosted). A Type 2 hypervisor runs on top of an existing host operating system such as Windows, macOS, or Linux. It relies on the host OS for device drivers, hardware interaction, and resource management. Examples include VMware Workstation, Oracle VirtualBox, and Parallels Desktop.

  Type 2 hypervisors are ideal for lab environments, testing, learning, and small-scale virtualization because they do not require dedicated hardware or direct hardware control. The host OS loads first, and the hypervisor runs as an application, allowing users to create and manage virtual machines from within the OS environment.

  Option B describes a Type 1 hypervisor , which installs directly on hardware without a host OS.

  Option A is unrelated, as firewalls are separate from virtualization technology.

  Option D is incorrect because hypervisors do not inherently increase CPU capabilities; they merely allocate existing hardware resources to virtual machines.

  Thus, the correct and CompTIA-aligned description of a Type 2 hypervisor is that it runs on a host operating system.

• Question 486:

  A customer has contacted you about building two new desktops. The first desktop will be a gaming workstation. The customer requirements include: Playing the newest games at a high frame rate Fast game load times Enough storage to have several games installed at once High-end audio No concern about cost Running the current Windows OS The second workstation will be a family workstation. The requirements include: Capability for word processing, videoconferencing, and basic web surfing Minimal cost, as long as it meets the requirements Running the current Windows OS

• Question 487:

  A technician is troubleshooting a connectivity issue on a network computer. The technician runs ipconfig in a command prompt and receives the following IP address:169.254.0.6.

  Which of the following is most likely the type of IP address being assigned?

  A. DHCP reservation assignment
  B. Dynamic assignment
  C. Self-assignment
  D. Static assignment
  C. Self-assignment

  ---

  Explanation

  An IP address starting with169.254.x.xis aself-assigned address(also calledAPIPA-Automatic Private IP Addressing). It's used when a client device cannot contact a DHCP server. This address allows limited communication on the local network segment butno internet access.

  Option A:DHCP reservations assign specific IPs from the DHCP server -- they don't result in APIPA.

  Option B:Dynamic assignment from DHCP assigns valid IPs in the proper subnet, not 169.254.x.x.

  Option D:Static IPs are manually set and would not fall in the 169.254.x.x range unless set incorrectly.

• Question 488:

  A user goes to their office and forgets their laptop charger. After borrowing a charger, the user notices that the battery is charging slowly.

  Which of the following steps should a technician take first to charge the battery normally?

  A. Adjust laptop battery performance.
  B. Try a different charging port.
  C. Use a different power supply.
  D. Replace the laptop battery.
  C. Use a different power supply.

  ---

  Explanation

  The most likely cause of slow charging after borrowing a charger is that the borrowed adapter is not the correct wattage or is not fully compatible with the laptop. Many laptops will still charge with an underpowered or non-matching adapter, but they often charge very slowly, may display a warning like "plugged in, not charging fast," or may reduce performance to stay within the available power budget. In CompTIA A+ Core 1 troubleshooting, the first step is to check the simplest and most probable cause, especially when the symptom began immediately after a change. Using the proper manufacturer-recommended charger (correct voltage/amperage and connector type, or correct USB-C PD wattage profile if applicable) restores normal charging behavior in most cases. Adjusting battery performance settings might reduce power draw but does not address the root cause of insufficient charger output. Trying a different charging port can help if a port is damaged, but the timing strongly points to the borrowed charger. Replacing the battery is the most invasive and least likely first step because the battery was presumably functioning before the charger change. Therefore, the technician should first use a different, known-good power supply with the correct specifications.

• Question 489:

  Which of the following is used to confirm that a physical port is working?

  A. Network tap
  B. Crimper
  C. Patch panel
  D. Loopback plug
  D. Loopback plug

  ---

  Explanation

  A loopback plug is a diagnostic tool used to test whether a physical port such as an Ethernet NIC port or serial port is capable of sending and receiving its own signal. When inserted, it "loops" outgoing signals back into the device, confirming the port's transmit/receive functionality.

  CompTIA A+ emphasizes loopback plugs as essential tools during hardware and network troubleshooting, especially when isolating physical port or NIC failures.

  Network taps passively monitor traffic, crimpers attach RJ45 connectors to cables, and patch panels organize cabling none of these verify port-level functionality. Therefore, only a loopback plug can confirm that a port is working correctly by testing signal integrity and hardware responsiveness.

• Question 490:

  An administrator is helping a new employee configure email on a smartphone. The employee also needs access to a shared mailbox.

  Which is the best email client for this situation?

  A. Open-source
  B. Built-in
  C. Corporate
  D. Employee preferred
  C. Corporate

  ---

  Explanation

  A corporate-provided email client is designed to integrate with enterprise services such as shared mailboxes, MDM policies, and enterprise authentication. CompTIA A+ states that corporate clients support additional management features, secure authentication protocols (such as OAuth or Kerberos), and policy-enforced access control essential for accessing shared or departmental mailboxes. Open-source clients (Option A) may lack compatibility with enterprise environments.

  Built-in smartphone clients (Option B) often don't support complex mailbox structures such as shared mailboxes. Employee-preferred apps (Option D) are discouraged because they may not meet security requirements.

  Corporate clients ensure full compatibility with organizational mail servers, shared folders, calendars, and enterprise security features, making corporate email clients the correct choice according to CompTIA's mobile device email configuration standards.
