CompTIA A+ Core 1 Certification Exam 220-1201 Practice Test 3

A high 80 Plus efficiency rating reduces wasted heat and power draw, and a modular design allows only needed cables to be connected, improving airflow in a tight case. The lowest wattage regardless of need, no fan, or rail design alone don't address efficiency or cable management.

Paper is hygroscopic and can absorb ambient moisture in humid conditions, causing it to curl, feed inconsistently, or jam more often, a common environmental cause unrelated to the printer's internal components.

Garbled output limited to specific applications, while another application prints correctly on the same computer and printer, points to a driver mismatch, such as using a PCL driver when the application expects PostScript output or vice versa. A fuser, roller, or toner issue would affect all print jobs regardless of application.

Since each subnet functions correctly internally but cannot reach the other, the issue is isolated to inter-subnet routing, most likely a missing or misconfigured route between the two subnets. DHCP failure or IP conflicts would affect address assignment within a subnet, not block traffic between two otherwise healthy subnets.

A charging port full of debris or physically damaged can prevent a reliable connection regardless of cable or outlet used, and a severely degraded battery may no longer accept a charge at all, both being the most likely hardware-level causes.

A faintly visible image without proper illumination on only the built-in display, combined with a normal image on an external monitor, points to a backlight or inverter failure specific to the laptop's own screen rather than a GPU or driver issue, since those would typically affect all outputs.

Since the issue is shared by both drives on the same controller/port multiplier while an unrelated drive on a different controller is unaffected, the common point of failure, the controller, multiplier, or its cable, is more likely than two coincidental drive failures.

Since moving the same RAM module to a different slot resolves the issue entirely, the original slot itself, rather than the RAM module, is the more likely fault. If the module itself were defective, moving it to a different slot would not have fixed the problem.

Data sovereignty concerns dictate where data is legally allowed to be stored and processed, critical for regulated data like patient records and directly affecting which cloud regions or providers are acceptable. Elasticity, multitenancy, and metered utilization are unrelated to legal data location requirements.

Allocation should be based on what physical resources the host actually has available beyond what's already committed, and on the expected demand of the workload the new VM will run. Console color scheme, MAC address, and the technician's own browser usage have no bearing on proper resource allocation.

A snapshot records changes relative to the VM's existing disk and typically resides on the same storage as the VM, so if the underlying host storage fails completely, the snapshot is lost along with the VM. Snapshots are not a substitute for genuinely separate backups and don't automatically replicate elsewhere.

Maintenance kit alerts are tied to a page count threshold for wear components like rollers and the fuser, which degrade with heavy use and should be replaced as routine preventive maintenance, separate from toner replacement.

Pushing printer drivers and connection settings through Group Policy or an endpoint management tool allows centralized, automated deployment across many workstations at once. Manual or per-user installs don't scale efficiently.

Since only the touchpad, the component nearest the spill, stopped functioning while the keyboard remains fine, the failure is most likely hardware-level damage in the touchpad assembly or its connector, requiring inspection and likely replacement. A driver reinstall, keyboard replacement, or Windows Update wouldn't fix physical liquid damage.

ECC (Error-Correcting Code) RAM detects and corrects single-bit memory errors in real time, important for servers where undetected corruption could affect data integrity.

Cat6a supports 10 Gigabit Ethernet over the full 100-meter distance, while standard Cat6 only supports 10GbE over shorter distances before signal degradation becomes an issue. Cat5e and Cat3 support much lower speeds.

The digitizer senses touch input, the backlight illuminates the LCD panel from behind, the LCD panel renders the image using liquid crystal cells, and an inverter board, on older CCFL-backlit displays, converts DC power to the AC needed to drive the backlight.

A Wi-Fi analyzer surveys the wireless spectrum, showing channel usage and signal strength from neighboring networks, confirming whether congestion is causing a dead zone. A cable tester, loopback plug, and punchdown tool are all designed for wired connections.

Fiber internet typically offers symmetrical upload and download speeds along with high reliability, well suited to video conferencing and large uploads. DSL is often asymmetrical and distance-limited, satellite has high latency, and dial-up is far too slow.

WPS's PIN-based pairing method is known to be vulnerable to brute-force attacks and should be disabled, and keeping firmware updated patches known vulnerabilities. Enabling WPS, downgrading firmware, or leaving default credentials unchanged would all weaken security.

/24 in CIDR notation means the first 24 bits identify the network portion of the address, equivalent to a subnet mask of 255.255.255.0, leaving the remaining 8 bits for host addresses.

An authoritative DNS server holds and answers queries for a domain's official records, and must be properly configured and reachable for the domain to resolve correctly from anywhere. DHCP, proxy, and NTP servers don't handle public domain resolution.

Port 993 is used for IMAP over SSL/TLS, handling encrypted retrieval of email by client applications. Ports 25 and 587 are used for sending mail, and port 143 is unencrypted IMAP.

Containerization, enforced through MDM or MAM policy, creates a separate secured space for corporate data on a personal device, allowing the company to wipe only that container without touching personal data. Encryption, camera restrictions, and PIN length don't separate corporate from personal data.

Miracast and similar wireless display standards let a laptop cast its screen to a compatible TV over Wi-Fi Direct without any cables. NFC is for close-proximity pairing, and HDMI/VGA both require a physical cable.
