Intermittent connectivity issues with network printers are commonly caused by changing IP addresses when using DHCP. Assigning a static IP address ensures that the printer is always reachable at the same IP address by client machines.

When printing on preprinted forms, precise alignment is critical. If print output shifts downward on the page, the first step is to ensure that the correct paper type and form stock are loaded properly. CompTIA A+ emphasizes verifying media type and tray configuration when dealing with alignment issues, especially in environments using specialized or preformatted paper.

Preprinted forms often require thicker media, specialty settings, or exact tray loading orientation to ensure feeding accuracy. If the wrong paper type is selected on the printer or print driver, the printer may adjust feed rate, roller pressure, or margin expectations incorrectly, causing vertical misalignment. Thus, confirming the correct paper type is loaded—and that the printer is configured for that type—is the most fundamental starting point.

Orientation settings (C) could affect sideways alignment but not vertical shifting. Pickup rollers (D) can cause skewing or paper jams, but they generally do not cause consistent downward shifts. PostScript drivers (B) relate to graphic rendering but do not affect form alignment unless dealing with complex images, which is not indicated here.

Therefore, confirming correct paper type and loading aligns with CompTIA’s troubleshooting methodology: always check the simplest, most likely physical cause first—especially with form printing.

Firewalls are specifically designed to monitor, filter, and control network traffic using Access Control Lists (ACLs). ACLs define which traffic is allowed or denied based on parameters like IP address, protocol, or port.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 – Networking hardware and security:

“Firewalls use access control lists (ACLs) to allow or deny traffic based on rules. Unmanaged switches and PoE injectors do not support ACLs.”

From the configuration, the Sales and Customer Service ports are hard-set to full duplex, 1000 Mbps, while the Marketing interface (GigabitEthernet0/3) is set to duplex auto and speed auto. CompTIA A+ explains that mismatched or lower-negotiated speeds and duplex settings can cause noticeable network slowdowns, collisions, and retransmissions—especially at busy times of the day when utilization is high.

Because all cabling is Cat 5e, it fully supports Gigabit Ethernet, so the cabling is not the limiting factor. The IP addresses are all in the same subnet (192.168.1.0/24) and formatted correctly, so there is no subnet or addressing problem. That rules out options A and C.

With speed auto, the Marketing port may be negotiating only 10/100 Mbps, or even a duplex mismatch (e.g., half duplex vs full). This would severely limit throughput compared to the gigabit links used by the other departments. In peak periods, that slower link would become congested first, which matches the users’ reports of performance degradation only in Marketing.

Therefore, the most likely cause is that the Marketing interface is operating at 10/100 instead of 1000 Mbps, making option D correct.

Mobile devices can share their LTE or cellular data connection using a feature called tethering, more commonly known as hotspot mode. According to CompTIA A+ objectives on mobile networking technologies, a hotspot allows a smartphone or tablet to become a mini wireless router, broadcasting a Wi-Fi signal that nearby devices can connect to. The LTE (or 5G) connection is then shared over Wi-Fi, enabling laptops, tablets, or other phones to access the internet through the mobile device.

Bluetooth is capable of tethering but provides much lower bandwidth and slower speeds—not ideal for sharing LTE widely. NFC is used for close-range data exchange or payment transactions and cannot share internet service. "Cellular" refers to the phone’s own mobile network connection, not the mechanism for sharing it with others.

Hotspot functionality is specifically built into modern mobile OSs and supports WPA2/3 encryption, password protection, and device whitelisting. This makes it the most common and efficient method to share LTE connectivity with multiple nearby devices.

Thus, Hotspot (D) is the correct answer.

Containers provide lightweight virtualization, ideal for deploying microservices because they are isolated, portable, and require fewer resources than traditional VMs.

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

“Containers package applications and their dependencies, making them ideal for running microservices efficiently and independently.”

High resource usage along with frequentpop-upsare strong signs of amalware infection. The next logical step is toupdate anti-malware definitionsandrun a full scanto detect and remove threats.

Option A:Network performance is likely not the root cause local system behavior points to malware.

Option B:Drivers affect hardware functionality; they don’t resolve malware-related slowness.

Option D:DHCP issues usually cause IP conflicts or no network access, not CPU spikes or pop-ups.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 4.2: Given a scenario, detect, remove, and prevent malware using appropriate tools and methods.

A DHCP reservation binds a specific MAC address to an IP address so the device always receives the same IP from the DHCP server. This ensures network devices like printers maintain consistent connectivity and availability even when the IP pool is low.
