If print quality remains poor after replacing the ink cartridge, the next step is to clean the printheads. Printheads can become clogged with dried ink, especially in inkjet printers, causing streaks or faded output.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 4.3 – Troubleshoot printing problems:

“Poor print quality after replacing cartridges is commonly caused by clogged or dirty printheads. Use the printer ' s cleaning cycle or manually clean the printheads as needed.”

Elasticity in cloud computing refers to the ability of a system to automatically allocate and release resources (such as CPU, RAM, or virtual machines) as workload demands change. This feature is key to ensuring that resources are used efficiently without manual intervention.

A port replicator expands the number and types of ports available to a laptop, including additional USB ports, video outputs, Ethernet, and more. CompTIA A+ identifies port replicators as solutions for users needing greater connectivity, especially when docking stations are unnecessary or unavailable.

Port replicators connect through a single USB or proprietary connector and provide multiple expansion ports instantly. This resolves the issue of limited USB availability without requiring hardware replacement.

NFC (A) is used for short-range communication, not peripheral connectivity. Bluetooth (B) only supports wireless peripherals such as mice and headphones, not wired USB devices. A USB receiver (C) adds wireless capability for one specific device, not general expansion.

Thus, the correct solution is a port replicator.

When a technician encounters a burning smell, it is a critical safety issue. The first response must be to immediately power down and disconnect the device from all power sources to prevent electric shock, fire, or further hardware damage.

From the CompTIA A+ 220-1101 Official Study Guide, Objective 4.1 – Troubleshoot common hardware problems:

" Signs of electrical issues such as burning smells, smoke, or sparks require an immediate shutdown of the system and disconnection from any power source. "

After ensuring safety, the technician should inspect the hardware for visible signs of damage:

From the same Objective (4.1):

" Inspect for foreign objects, liquid damage, or burnt components. These can cause short circuits or thermal events that may damage the motherboard or other internal components. "

These steps are standard practice in the industry to ensure safe and accurate diagnosis of faulty devices. Trying a different adapter (Option F) may make the problem worse, and contacting vendors (Option D) comes after initial safety and inspection.
