The most effective solution to resolve this issue and prevent it from happening again is to assign the printer a static IP address. According to CompTIA Core 1 (220-1201) networking and printer configuration objectives, network printers should use static IP addresses to ensure consistent accessibility by client devices.

In this scenario, the printer was initially reachable using its assigned network address, but after several days it became unavailable. This commonly occurs when the printer is configured to receive its IP address via DHCP. When the DHCP lease expires or the printer is rebooted, the router may assign a different IP address, causing all workstations configured with the old address to lose connectivity.

By configuring a static IP address (or DHCP reservation), the printer’s IP address remains constant, ensuring that all workstations can reliably send print jobs without interruption.

A network gateway is used to route traffic between networks and does not address printer addressing issues. A USB cable would eliminate network printing entirely and is not appropriate for a SOHO network environment. APIPA addresses indicate a DHCP failure and would worsen connectivity rather than fix it.

CompTIA strongly emphasizes using static IP addressing for shared network devices such as printers to ensure stability and prevent recurring access problems.

An uninterruptible power supply (UPS) protects systems against power outages by providing temporary backup power, giving users time to save data and safely shut down.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.3 – Power protection:

“A UPS supplies backup power to prevent data loss and hardware damage during outages or surges, ensuring system integrity.”

A hypervisor allows multiple operating systems to run simultaneously on a single physical host, making it the ideal solution for providing concurrent access to different test environments. Developers can use virtual machines (VMs) for testing and development.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.7 – Compare and contrast cloud computing concepts:

“A hypervisor is software that enables multiple operating systems to run on a single host as virtual machines. This is commonly used in development and testing environments for flexibility and isolation.”

The first consideration for a desktop CPU upgrade is the socket type, because the processor must be physically and electrically compatible with the motherboard. In CompTIA A+ Core 1 hardware terms, CPUs are designed for specific sockets (for example, Intel LGA or AMD AM-series), and a mismatch means the CPU simply cannot be installed. Even within the same brand, different generations may use different sockets, and the motherboard’s chipset and BIOS/UEFI must also support the selected CPU model. If the socket is wrong, factors like core count, frequency, and integrated graphics become irrelevant because the system will not POST or function.

After confirming socket compatibility, the technician would typically evaluate other constraints such as BIOS/UEFI update requirements, power and cooling (TDP and heatsink/fan capability), and RAM compatibility supported by the platform. Only then do performance-related preferences like core count (multitasking), bus/clock characteristics, or whether an integrated GPU is needed (if no discrete video card is present) become meaningful selection criteria. Therefore, the correct first consideration is the motherboard socket type.

Bluetooth audio issues are typically related to distance and signal strength, not internet connectivity or Wi-Fi access points. Bluetooth devices—especially headsets—generally have a limited effective range of around 10 meters (33 feet) for Class 2 Bluetooth, which is common in consumer laptops and headsets. When the user leaves the room and walks into adjacent offices, they are likely moving beyond the optimal Bluetooth range or passing through walls that weaken the signal.

CompTIA A+ highlights that Bluetooth uses low-power radio frequencies easily disrupted by physical obstructions, distance, and interference. Since the laptop remains stationary and the user moves, the headset becomes progressively further from the laptop, causing intermittent audio dropouts, stuttering, or loss of connection.

The number of APs (A) is irrelevant because the headset is not using Wi-Fi. Mesh mode (C) applies only to wireless AP-to-AP communication. The internet connection (D) is high-quality fiber and conference calls work fine when stationary, so the issue is not bandwidth or WAN throughput.

Thus, the most likely cause is that the user is moving in and out of Bluetooth range.

A modular power supply is the best choice when cable management is a priority. According to CompTIA Core 1 (220-1201) power supply objectives, modular PSUs allow technicians to connect only the cables that are needed for the system’s components, reducing clutter inside the case.

This improves airflow, simplifies troubleshooting, and creates a cleaner internal layout, which is especially beneficial in home-built desktop systems. Semi-modular and fully modular power supplies offer varying degrees of flexibility, but all modular designs reduce unused cables compared to standard power supplies.

A standard (non-modular) power supply has all cables permanently attached, often resulting in excess unused cables that obstruct airflow. A backup power supply refers to an uninterruptible power supply (UPS), which provides battery backup but does not improve internal cable management. A redundant power supply is typically found in enterprise servers and includes multiple PSUs for fault tolerance, not cable management.

CompTIA emphasizes modular power supplies as a best practice for clean builds and efficient system design, making this the correct answer.

When a device shows asnot connectedeven though it previously paired, the most effective action is tore-pair the devices. This resets the Bluetooth connection, clears any corruption in pairing profiles, and re-establishes communication.

Option A:Entering a PIN is only relevant during initial pairing and may not be prompted again.

Option B:Turning off Wi-Fi doesn’t typically affect Bluetooth; they operate on similar frequencies but don’t conflict this way in normal use.

Option D:If Bluetooth were disabled, the device wouldn’t appear at all, not just show as “not connected.”
