220-1202 Exam Preparation Material | CompTIA A+ Certification Exam: Core 2

Explanation:
The correct syntax for mapping a network drive in Windows is:
net use Z: \\WinNAS\shared
This command connects the specified network share and maps it as drive Z:.
From Travis Everett C CompTIA A+ All-in-One Exam Guide:
“Use net use followed by the desired drive letter and the UNC path to map network shares.”

Explanation:
Adding ten high-end graphics/animation desktops can dramatically increase the electrical load on the room’s existing circuits. High-performance CPUs and GPUs draw substantially more wattage than typical office PCs, and that wattage translates into higher current (amperage) on the circuit. Mike Meyers’ Lab Manual explains the relationship V × A = W and warns that wiring and circuits have amperage ratings; pushing too much current can overheat wiring and trigger safety devices. It also explains that circuit breakers are rated for a specified amperage and will open (trip) when overloaded to prevent overheating and damage. Therefore, before deployment, the technician should calculate expected power draw per system and ensure the desktops are distributed across sufficient circuits (or that electrical upgrades are made) to avoid repeated breaker trips, overheating risks, and downtime. While temperature and humidity matter for environmental control, the question is specifically about introducing multiple power-hungry workstations, making circuit power consumption the most critical planning factor for safe, stable operation. This aligns with A+ operational/environmental concepts around proper power handling and avoiding overload conditions.

Explanation:
This scenario is phishing delivered through a QR code (scan an image to reach a portal), which is best described as quishing. Quentin Docter defines phishing as a social engineering method where the attacker makes a message look legitimate and convinces the user to click a link to “correct” an account problem; after the click, the victim is taken to a site controlled by the attacker and asked for credentials. A QR code in a message is simply an alternate way to deliver that same malicious “link” without showing the URL clearly.
The Mike Meyers Lab Manual distinguishes related social engineering types: vishing is done by phone calls, and whaling targets high-level executives. Smishing is phishing delivered via SMS text messages, but the prompt specifically centers on scanning an image (QR-style workflow), not a text-message attack vector.
Docter also notes QR codes are commonly used in authentication workflows (for example, adding accounts to authenticator apps), which is why attackers mimic this behavior to make the scam seem normal. Therefore, QR-based phishing is best labeled quishing.

Explanation:
The symptoms suggest a browser hijacker. The first steps should be to remove any malicious extensions and reset the startup page to restore normal behavior.
From All-in-One Exam Guide:
“Browser hijackers often install as extensions and change homepage settings. Removing these extensions and resetting the startup configuration typically resolves the issue.”
