SSH (Secure Shell) encrypts data communications for secure remote login and management of network devices, ensuring all console connections are encrypted.

Why Not B (LDAP): LDAP is used for directory services and does not encrypt by default.

Why Not C (FTPS): FTPS encrypts file transfers, not console communications.

Why Not D (SMTP): SMTP is used for email transmission, not for securing login sessions.

Laptop display assemblies typically include not only the LCD panel but also the webcam, microphone, display cable, and critically, the Wi-Fi antennas. In most laptops, Wi-Fi antennas are built into the display bezel, because the elevated position allows for stronger wireless signal reception. When replacing the entire display assembly, the antennas must be carefully disconnected and reconnected during reinstallation.

CompTIA A+ emphasizes proper cable routing and antenna reattachment as essential steps in laptop hardware disassembly and reassembly. Failing to reconnect these antennas results in weak or nonfunctional wireless connectivity, even though the display replacement itself may be successful.

Heat sinks and CPU fans are located on the motherboard and are unrelated to display assembly replacement. Resetting BIOS settings is unnecessary unless troubleshooting firmware-related issues, not replacing hardware components like a display. Therefore, the only action that aligns with standard laptop design and CompTIA A+ procedures is ensuring that the wireless antennas are reconnected.

Thus, the correct answer is B.

CompTIA A+ teaches that S.M.A.R.T. warnings indicate imminent drive failure. Even if the RAID controller reports the array as “healthy,” a S.M.A.R.T. alert means the drive should be replaced immediately.

RAID 5 provides redundancy for one drive failure, but technicians should replace the degrading drive before it fails fully, ensuring the rebuild happens proactively.

Running chkdsk affects file systems, not drive health. Disabling write caching is unrelated. Rebuilding the array should only occur after replacing the faulty drive.

Replacing the drive prevents a catastrophic dual-drive failure scenario, which RAID 5 cannot survive.

This approach aligns with CompTIA troubleshooting guidelines for RAID maintenance and S.M.A.R.T. diagnostics.

A spam gateway filters unsolicited emails at the server level, significantly reducing spam before it reaches user inboxes.

Why Not A (Load balancer): Load balancers distribute traffic but don’t filter spam.

Why Not C (Mail forwarding): Forwarding doesn’t filter spam.

Why Not D (Proxy servers): Proxies control web traffic, not email filtering.

Badging is a form of authentication that requires employees to use a badge or ID card to release print jobs. This solution reduces unnecessary printing by ensuring only authorized users print.

Why Not A (Access control list): While ACLs manage permissions, they are not used for physical authentication at printers.

Why Not B (Audit logging): Audit logs track actions but do not restrict printer access.

Why Not D (Print server): A print server manages print jobs but doesn’t enforce authentication.

Portable devices such as laptops, small-form-factor computers, and mini-PCs use SODIMM (Small Outline DIMM) memory modules. CompTIA A+ explains that SODIMMs are physically smaller and consume less power than standard DIMMs, making them ideal for mobile systems where space and energy efficiency are critical. Unlike ECC memory, which is primarily used in servers, or RAID which is a storage redundancy methodology rather than a memory type SODIMM is specifically designed for compact computing devices. SATA is a storage interface, not a memory form factor.

The A+ study guide clearly lists SODIMM as the standard laptop memory type because of its compact footprint and compatibility with mobile motherboard layouts. This makes SODIMM the most widely implemented memory technology in portable devices.

In a corporate office environment where multiple employees must share a single printer, the most efficient and manageable solution is a print server. A print server centralizes print management, queues print jobs, handles driver distribution, and provides access control. CompTIA A+ highlights print servers as the enterprise-standard method for managing shared printing resources because they ensure reliability, scalability, and better network performance.

Bluetooth printing and Wi-Fi Direct are short-range, peer-to-peer technologies meant for one-to-one or small-scale printing. They lack user authentication management, enterprise security controls, and cannot efficiently support dozens or hundreds of print requests simultaneously. Cloud printing requires internet reliance and external service routing, which introduces latency, potential downtime, and privacy concerns—often unsuitable for corporate networks, especially those with sensitive internal documents.

A print server allows users to connect to the printer through a standard network infrastructure (wired or wireless), and technicians can configure permissions, monitor print loads, and troubleshoot from a central location. It integrates seamlessly with enterprise directory services such as Active Directory, enabling controlled access and auditing. Because of these capabilities, the print server is the best professional-grade solution for corporate-wide printing needs.

CompTIA A+ teaches that vertical lines on scanned or copied documents but not printed documents indicate a dirty or smudged scanner glass or ADF glass strip. Dust, ink smears, or debris create a line because the scanning sensor repeatedly passes over the same contaminated area.

If printing works normally, internal printer components such as the transfer roller or pickup rollers are not at fault. Maintenance kits apply to internal wear components like rollers, belts, or fusers not scanning artifacts.

Cleaning the scanner glass or ADF strip directly addresses this common problem. The A+ exam frequently includes troubleshooting questions about print vs. scan artifacts, and this scenario is a classic example.

Therefore, the correct solution is to clean the glass bed (or ADF strip).

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.
