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

Repeated clicking combined with the drive not being detected at all is a well-known symptom of mechanical failure inside a hard drive. A loose cable would typically cause intermittent detection, and a corrupted file system or outdated driver would usually still let the drive be detected.

An acceptable use policy defines what software, systems, and behavior are permitted on company equipment, and installing pirated software directly violates that policy. An NDA and MNDA govern confidentiality, and an SLA defines service expectations, none of which govern acceptable software use.

Reviewing equipment placement, airflow clearance, and dust buildup directly addresses a gradual temperature increase tied to inadequate ventilation. A UPS addresses power continuity, and Wi-Fi channels or firewall rules are unrelated to physical temperature management.

Getting help or using proper lifting equipment for a heavy item directly prevents back and other physical injuries. Disconnecting power, wearing an ESD strap, or applying thermal paste don't address the physical risk of lifting a heavy object.

Checking recently installed apps helps identify the likely source of both the ads and the new battery drain, and reviewing per-app battery statistics confirms which app is responsible. Autorotate, ringtone, and contacts settings are unrelated to ad injection or battery drain.

A shutdown that only occurs under demanding sustained load, with no issues during light use, points strongly toward thermal shutdown protection triggering due to inadequate cooling. Account passwords, browser installation, and mouse batteries are unrelated to load-triggered thermal shutdowns.

A certificate warning isolated to just one specific site, while every other site works fine, points to a problem with that one site's certificate rather than a system-wide clock or DNS issue. If the system clock were wrong, it would typically cause warnings across many sites, not just one.

BitLocker encrypts an entire drive at the disk level, so removing it and connecting it elsewhere leaves the data unreadable without the recovery key, unlike EFS which encrypts individual files. A screensaver password and firewall don't provide disk-level encryption.

Each stage plays a distinct role in incident response: isolating the device stops further spread, preserving evidence supports any later investigation, removal eliminates the actual threat, and documentation captures the incident for future reference.

EDR specifically monitors endpoint behavior for suspicious activity and can automatically respond, including isolating a compromised device from the network. A basic signature-based antivirus alone typically can't isolate a device, and a firewall or VPN concentrator operate at the network level.

SPF publishes a list of servers authorized to send email for a domain, letting receiving servers check whether a message actually came from an approved source. MFA secures logins, an ACL controls resource access, and DLP prevents sensitive data from leaving an organization.

A VPN connection creates a secure, encrypted tunnel back to headquarters so a remote worker can reach internal resources from any external network. A metered connection, proxy exception, and network discovery settings don't provide secure remote access to internal resources.

Personalization settings control both the desktop background/lock screen and, within its taskbar section, whether the search box appears. Ease of Access, Network and Internet, and Privacy don't control desktop background or taskbar search visibility.

Running cd with no arguments in Windows Command Prompt displays the current directory's full path, a quick way to confirm where the prompt is currently pointed.

msinfo32 compiles hardware, driver, and startup program details into a single comprehensive report that can be saved and shared. Disk Cleanup frees storage space, Character Map inserts special characters, and Notepad is a plain text editor.

A docking station consolidates power, video, USB peripherals, and wired network into a single connection point. A stylus and trackpad are input devices, and a video-only port replicator wouldn't handle keyboard, mouse, and network needs.

Beep codes that change based on which RAM stick is installed are the motherboard's way of reporting a memory-related hardware failure before the OS even attempts to load. A failing hard drive, corrupted Windows installation, or failing NIC wouldn't produce POST beep codes tied to which memory stick is installed.

Vertical lines on every printed page typically point to a worn or damaged drum/cartridge, and a stuck queue with jobs piling up is commonly resolved by clearing the queue and restarting the print spooler service. Changing IP address, adjusting a display theme, or disabling Wi-Fi don't address either issue.

Intermittent connectivity affecting multiple users on the same switch, while a different switch is unaffected, points to a shared point of failure like the switch, a bad port, or shared cabling. BIOS settings, monitor cables, and UPS battery health don't explain a shared, switch-specific connectivity pattern.

Elasticity is the ability to scale resources up and down on demand, and IaaS provides the underlying compute infrastructure without owning physical servers. Multitenancy/SaaS describes shared software delivery, a private cloud implies dedicated resources, and a hybrid cloud with on-premises servers contradicts avoiding physical maintenance.

Running the legacy OS inside a virtual machine lets the old application keep running in its required environment while retiring the aging physical hardware. A Type 1 hypervisor replacing the desktop OS, desktop virtualization streaming, or a container with a different modern OS don't preserve the specific legacy OS environment needed.

Each term describes a distinct RAM characteristic: SODIMM is a compact form factor for laptops, ECC RAM adds error correction typically used in servers, dual-channel is a slot-pairing configuration for bandwidth, and DDR refers to the memory generation defining speed and voltage standards.

A laser printer maintenance kit bundles the parts and procedures, like replacing key rollers and cleaning components, needed for a routine deep maintenance service after extended use, distinct from simply swapping a toner cartridge alone.

Network scan-to-email services let the printer itself send scanned documents directly to a specified email address, requiring no client-side software. USB connectivity, printer sharing, and duplex printing are valid printer features but don't address scan-to-email delivery.

A power supply that worked fine before a GPU upgrade but now trips under load strongly suggests the new GPU's higher power draw is exceeding the PSU's wattage rating. RAM, CPU cooling, and monitor cables are unrelated to a power-triggered overload under GPU load.

A VPN creates a secure private connection between the two office locations over the public internet, and a LAN describes the internal network confined to a single floor or building. A SAN is dedicated storage networking, a MAN spans a larger metropolitan area, and a WISP is an internet service provider type.

A DHCP scope defines the overall range of addresses to hand out automatically, and exclusions can set aside a portion of that range for manually assigned devices. Static routing/NAT, VLAN tagging/trunking, and port forwarding/DMZ are unrelated to reserving addresses within a DHCP scope.

Each device serves a distinct role: a router moves traffic between networks, a managed switch allows configuration like VLANs and port-level monitoring, an access point bridges wireless clients to the wired network, and a patch panel organizes and terminates structured cabling.

A DHCP reservation ties a specific IP address to a device's MAC address within the DHCP server's configuration, so that device always receives the same address automatically. An exclusion removes addresses from the pool, a smaller scope limits the range, and shortening lease time only affects renewal frequency.

MDM under a BYOD policy can isolate corporate data in a managed container that can be selectively wiped, leaving personal content untouched. Bluetooth tethering, GPS, and a personal VPN app don't provide managed, separable corporate data control.
