The customer wants to consolidate multiple physical servers running different operating systems, including Windows, Linux, and Unix, while maintaining strong isolation between systems. CompTIA A+ identifies Infrastructure as a Service (IaaS) as the best model for hosting fully isolated virtual machines in a cloud environment, allowing each OS to run independently on its own virtual hardware.

IaaS provides virtualized computing resources—CPU, RAM, networking, and storage—while allowing the customer full control over the OS and application layer. This means Windows, Linux, and Unix VMs can coexist without compatibility concerns because each VM runs its native OS without modification.

Containers (B) are unsuitable because they share the host OS kernel, meaning they cannot run different OS families. A Type 2 hypervisor (C) is workstation-based and not designed for enterprise server consolidation. VDI (D) provides user desktops, not server workload consolidation.

Thus, IaaS is the correct solution for compatibility, isolation, and consolidation across multiple OS types.

Mobile Application Management (MAM) enforces policies restricting access to apps and services based on location, ensuring security at external sites.

Why Not A (MOW): "Mobile Only Workplace" (MOW) is not a recognized term in this context.

Why Not B (MAN): Metropolitan Area Network (MAN) is unrelated to mobile device policies.

Why Not C (MFA): Multi-Factor Authentication secures user accounts but does not enforce app restrictions.

Physical damage from dropping a tablet may often affect ports or connectors. Before taking deeper diagnostic or replacement steps, it's important to visually inspect the USB-C charging port for damage or debris. If the port is damaged, charging issues can occur regardless of battery health.

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.

Assigning a static IP to network printers ensures the printer's address does not change after outages or DHCP lease expirations, preventing connectivity issues.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.4 – Printer network configuration:

“Printers should use static IPs to ensure they remain reachable and do not change addresses after network events.”

Gaming laptops prioritize speed, low latency, fast read/write times, and quick loading. CompTIA A+ explains that NVMe M.2 SSDs provide the fastest consumer storage available due to their use of the PCIe bus, which delivers significantly higher performance compared to SATA-based drives.

HDDs (Options A and C) are mechanical and have slow seek times, making them unsuitable for high-performance gaming. SAS SSDs (Option D) are enterprise-grade, rarely used in laptops, and require SAS controllers not found in consumer systems.

Thus, a 512GB NVMe M.2 SSD offers the best performance, fastest boot times, rapid texture loading, and optimal gaming responsiveness fully aligning with A+ hardware performance recommendations.

When a laser printer intermittently fails to feed paper, the most common hardware cause is worn or dirty pickup rollers. These rollers grab the paper from the tray and move it into the printer. Over time, dust, paper debris, or worn rubber reduces their effectiveness, causing feeding issues.

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

“If the printer is not picking up paper correctly or is experiencing paper jams, check and clean or replace the pickup rollers and separation pads as these are responsible for feeding paper into the print path.”

Other options like updating drivers, selecting paper size, or replacing toner will not resolve a mechanical paper feed problem.

C. Installing redundant PSUs (Power Supply Units):

Redundant PSUs provide fault tolerance by ensuring that if one power supply fails, another will take over seamlessly.

This is a cost-effective way to increase uptime while waiting for the UPSs to arrive.

Incorrect Options:

A. Purchasing backup generators: Generators are costly and are typically used for long-term outages, not as an immediate or cost-effective solution.

B. Increasing input voltage: This is not a practical solution to hardware failures or power issues.

D. Activating a hot site: A hot site is an expensive, fully operational backup facility that would not be a cost-effective solution for this scenario.

Key Takeaway: Installing redundant PSUs is a cost-effective way to balance uptime requirements in case of power or hardware failure.
