CompTIA A+ Core 1 & 2 (V15) Exam Practice Test 1

A cracked screen requires physical inspection and likely replacement, and new unexplained heat after a drop warrants checking for a damaged battery or a ventilation path obstructed in the fall. Reinstalling the OS, resetting Wi-Fi, or clearing browser cache don't address either the physical damage or the new heat issue.

gpresult displays the Group Policy settings that have actually been applied to a computer or user, letting a technician confirm whether a new policy took effect, unlike gpupdate, which refreshes policy but doesn't report on what's applied.

A rollback plan documents how to undo the change if something goes wrong, and a sandbox or test plan documents how the change will be verified before going live, both standard, necessary elements of a change request. The remaining options are unrelated to the technical and risk management content a change request needs.

An SOP documents the exact steps for a routine, repeatable process like requesting new equipment, giving every employee the same current reference. Incident reports document specific past events, topology diagrams show network layout, and compliance documents address regulatory requirements.

No drive activity at all combined with an unchanged percentage for hours indicates the update process has genuinely stalled rather than just being slow, which is when a forced restart becomes appropriate. A monitor cable or keyboard issue wouldn't explain an update stuck mid-process.

App stores often need extra temporary space beyond an app's final size to stage an update, and accumulated cache or leftover temporary files can trigger a storage error even when the general free-space total looks sufficient. Wi-Fi credentials, SIM cards, and Bluetooth are unrelated.

A freeze isolated to one graphically intensive application strongly points to a GPU driver issue specific to that workload. Update history, account permissions, and network settings wouldn't explain a freeze tied to one specific 3D application.

Each technique targets a different vector: vishing is phone-based, whaling is a targeted attack on a high-value individual, tailgating exploits physical entry points, and shoulder surfing exploits visual observation of credentials.

EFS ties file encryption to a specific user's credentials, so the file stays unreadable on a different machine without those credentials, while decrypting transparently for that user on the original system. The firewall, Group Policy, and UAC don't provide file-level encryption.

A mantrap, or access control vestibule, is specifically designed to prevent tailgating by only allowing one verified person through at a time. Phishing, denial-of-service, and brute-force attacks are unrelated to physical entry control.

Windows 11 Home is the most cost-appropriate choice for a small home-office workgroup with no domain join or enterprise management requirements, since Pro and above add cost and features that aren't needed here.

Installing from an internal recovery partition uses locally stored image data on that single machine, requiring no network connection, unlike PXE, zero-touch, or remote network installs which all depend on network infrastructure.

GPT (GUID Partition Table) supports more than 4 primary partitions and drives beyond the 2TB limit MBR imposes. MBR is limited to 4 primary partitions and 2TB drives, and FAT32/exFAT are filesystem formats, not partition table types.

A swelling battery is a fire and chemical hazard and should be removed and disposed of properly right away rather than continuing to use or charge it. Continuing use, taping it, or attempting to fully charge it all increase the risk of fire or injury.

Gradually dimming brightness and color shift over time, without distortion or connection symptoms, are classic signs of an aging display panel or backlight. A loose cable or incorrect input would typically cause total loss of image rather than a slow color/brightness shift, and a failing GPU would more likely show artifacts or crashes.

RAID 5's parity data allows the array to keep functioning with one failed drive, which is what degraded mode means, and the amber LED on just one drive confirms that drive is the failure. If the controller had failed, the array typically would not be accessible at all, and reformatting would destroy recoverable data.

A brief flicker of power followed by immediate shutdown, repeating in a cycle, is a classic sign of a power supply that can't sustain the load or isn't properly seated. A GPU driver, boot loader, or account password wouldn't prevent the system from completing POST or holding power at all.

A Type 2 hypervisor runs on top of an existing host OS and lets multiple full virtual machines, each running its own isolated guest OS, run side by side. A single container doesn't provide full OS isolation, a Type 1 hypervisor is typically used on dedicated server hardware, and application virtualization alone doesn't provide full OS-level isolation.

Each connector type serves a distinct role: PCIe hosts expansion cards, SATA connects traditional drives, M.2 connects compact SSDs directly to the board, and the 20+4 pin connector delivers primary power from the power supply to the motherboard.

NVMe, when run over a PCIe-wired M.2 slot, offers significantly higher throughput than SATA-based interfaces like SATA or mSATA, making it the fastest choice. SAS is typically used in server/enterprise storage rather than consumer M.2 slots.

Dual-channel mode requires RAM sticks to be installed in the specific paired slots the motherboard manual designates, usually color-coded, to actually gain the bandwidth benefit. Installing without regard to pairing, using ECC RAM, or matching form factor to case size don't enable dual-channel operation.

A syslog server is specifically designed to collect and centralize log messages from many network devices for later review and troubleshooting. DNS resolves names to addresses, a print server manages print jobs, and a web server hosts web content, none of which centralize logs.

Microwave ovens commonly interfere with the 2.4GHz band because they operate in a similar frequency range, an issue much less common on 5GHz or 6GHz. This is a well-known source of interference for dual-band Wi-Fi devices operating in the 2.4GHz range.

Port 443 is the standard port for HTTPS, encrypting web traffic between a browser and server, as opposed to port 80 which is used for unencrypted HTTP.

A Bluetooth headset provides hands-free audio, and a stylus allows direct sketching or note-taking on a touchscreen, directly matching both needs. A docking station and port replicator expand physical peripheral connectivity, and a trackpad is an alternate pointing device, none of which address audio or sketching.
