CompTIA A+ Core 1 & 2 (V15) Exam Practice Test 4

exFAT is natively supported by both Windows and macOS without extra software and supports files larger than 4GB. NTFS requires extra software for full write support on macOS, and APFS/ext4 are native to macOS and Linux respectively.

Change board approval, or approval from the change advisory board, is the formal review and sign-off step within change management that confirms appropriate stakeholders reviewed and approved a proposed change before implementation.

Each documentation type serves a different purpose: an incident ticket records a specific issue and its resolution, a CMDB centralizes asset and configuration records, an SOP documents a repeatable routine process, and a knowledge base article provides a searchable reference for previously solved problems.

The concern about proprietary code being used to improve a public model is a private vs. public data handling issue, and confidently suggested but incorrect code is a hallucination issue. Bias, integration complexity, and licensing cost are separate AI governance topics not described here.

Intermittent display loss that worsens under heavy GPU load points toward a GPU cooling or driver stability issue. Keyboard layout, wallpaper settings, and printer connectivity have no relationship to GPU-load-triggered display loss.

Browser tabs opening on their own to advertising sites is characteristic of a browser hijacker or adware, and files renamed with an unfamiliar extension strongly suggests a ransomware infection. A monitor cable, printer driver, or Bluetooth pairing issue would not explain either symptom.

An unrecognized app with broad permissions running unexplained background activity overnight is a strong indicator of an unauthorized or malicious application. Autorotate, call log, and wallpaper settings are unrelated to unauthorized background app activity.

An app crashing specifically right after an OS update, while other apps remain unaffected, points to an app compatibility issue that a pending app update is likely to resolve. Wi-Fi, SIM, and battery issues are unrelated.

RADIUS combined with 802.1X authentication allows each user to authenticate with their own individual credentials on the wireless network. A pre-shared key is exactly the shared-password model being replaced, WEP is outdated and insecure, and disabling SSID broadcast only hides the network name.

Each Windows security feature addresses a distinct risk: BitLocker protects data if a drive is physically removed, UAC prevents silent privilege escalation, the firewall controls network traffic, and EFS restricts access to specific files even for other users of the same machine.

DLP with removable media restrictions specifically monitors and can block unauthorized copying of sensitive data to USB drives. A Wi-Fi password, access control vestibule, and BIOS password address different risks rather than USB-based data exfiltration.

A password manager that strictly validates the exact domain before autofilling won't release saved credentials on a look-alike domain. A pop-up blocker, private browsing, and clearing history don't verify domain authenticity.

Marking a saved Wi-Fi network to connect automatically in its properties makes Windows join that network without prompting whenever it's in range. Airplane mode disables wireless entirely, and network location or metered connection settings control sharing/data behavior, not automatic reconnection.

The sc command (Service Control) can query a specific Windows service's configuration and status directly from the command line, offering a faster alternative to the full Services graphical console.

Image deployment pushes a single prepared reference image, including installed applications and settings, to many machines at once. A repair install fixes an existing installation, an in-place upgrade updates an existing OS, and each laptop's own recovery partition wouldn't provide the same custom configuration across all machines.

An isolated failure of just the front camera after a physical drop points to that specific camera module being damaged, making targeted replacement appropriate. A motherboard, battery, or OS reinstall wouldn't be the first response to one physically damaged camera module.

Dead pixels are permanently stuck, non-responsive points on the panel, and flickering that worsens with heat often points to backlight or panel component degradation. An incorrect input source or loose cable would typically show no signal rather than these specific symptoms.

A S.M.A.R.T. warning for reallocated sectors is an early indicator of a drive nearing failure, so proactively replacing it helps avoid a more serious failure later. Ignoring the warning, reformatting the whole array, or disconnecting the NAS entirely are all disproportionate or risky responses.

A complete absence of any power indication points to a power delivery problem, either the PSU itself, its connection, or the wall outlet, since the system isn't even reaching POST. A GPU driver, hard drive, or Windows installation issue would require the system to at least power on first.

A single stuck job blocking the entire queue, with no hardware error indicated, is typically resolved by clearing that job and restarting the print spooler service. Replacing toner, updating firmware, or rebooting the whole network don't address a queue-level software issue.

Multitenancy describes multiple customers sharing the same underlying infrastructure while keeping their data logically separated. Elasticity refers to scaling resources, a private cloud implies dedicated infrastructure, and a community cloud is shared among organizations with common concerns.

A sandbox virtual machine provides an isolated, disposable environment specifically designed for testing potentially risky files. A production hypervisor cluster, desktop virtualization for end users, and a container sharing the production OS all carry more risk for this use case.

An M.2 form factor provides the compact size needed for a thin laptop, and NVMe provides the fastest available interface for that form factor. A 3.5-inch form factor is too large for a thin laptop, SAS is typically server-focused, and optical drive bay compatibility is unrelated.

Adding RAM correctly requires following the motherboard's documented channel configuration so the new sticks pair properly with the existing ones. Using different speeds, mismatched form factors, or mixing ECC with non-ECC RAM can cause instability.

Running the built-in print head cleaning cycle is the standard first response to streaky color caused by clogged nozzles. Replacing the whole printer, the paper tray, or updating firmware don't address a clogged print head directly.

Secured or badge-release printing holds a job until the requesting user authenticates at the printer itself, directly preventing sensitive documents from sitting unattended. Duplex printing, tray settings, and firmware updates are unrelated to authentication-based print release.

Each device or concept plays a distinct role: a firewall filters traffic by rule, a load balancer spreads traffic across multiple servers, a proxy server relays and can filter requests on a client's behalf, and a cable modem provides internet access over coaxial cable infrastructure.

A VLAN segments the guest traffic logically from the corporate network, and VLAN tagging on the trunk port ensures that segmented traffic is correctly identified as it passes between switches. NAT, a DMZ, and port forwarding are unrelated to VLAN segmentation or trunk tagging.

A DNS server translates human-readable domain names into the numeric IP addresses computers use to communicate. DHCP assigns IP addresses, a print server manages print jobs, and a syslog server centralizes log messages.

USB-C supporting DisplayPort Alt Mode and Power Delivery can carry both high-bandwidth video and charging power over a single cable. VGA is an older analog standard with no power delivery, and DB9/RJ11 are serial and telephone connectors unrelated to video or charging.
