CompTIA A+ Core 1 Certification Exam 220-1201 Practice Test 5

The motherboard's chipset governs many available I/O features, such as additional USB and SATA ports and certain PCIe lane allocations, independent of the CPU itself, which is why two boards supporting the same CPU can offer different I/O capabilities.

Replacing a router often resets DHCP assignments, so a printer's IP address may change even though it remains powered on and connected to Wi-Fi, breaking existing print connections configured with the old address.

Connecting two ports on the same switch together, without a loop prevention protocol like Spanning Tree Protocol (STP) active, creates a switching loop where broadcast traffic circulates endlessly, rapidly degrading the entire network.

Freeing storage directly addresses the near-full capacity causing crashes and sluggish performance, and restarting the device afterward clears temporary memory and lets the system recognize the newly available space.

Since the hardware works fine in other apps, the issue is isolated to this specific app's access, and OS updates sometimes reset or require re-granting of camera and microphone permissions for individual apps.

When two monitors use different resolutions and DPI scaling settings, moving windows between them can cause the operating system to render text and icons incorrectly on one display, a scaling configuration issue rather than a hardware fault.

SSD flash memory cells have a finite number of write cycles, and as they wear out over years of use, the drive's controller may reduce available capacity or write performance to maintain reliability, a normal aging characteristic of SSDs.

Many modern power supplies use semi-fanless or zero-RPM modes that keep the fan off at low system loads, so a stationary PSU fan isn't automatically a failure; the technician should check the PSU's specification to confirm expected behavior.

Cloud computing's on-demand, pay-as-you-go consumption model lets companies pay only for what they use on an ongoing basis, avoiding the large upfront capital expenditure required to buy and maintain physical servers.

A hybrid cloud model combines privately controlled infrastructure for sensitive workloads with public cloud resources for less sensitive, publicly facing needs, letting the two work together as one overall solution.

A VM template or clone captures a pre-configured base VM's state, allowing it to be rapidly duplicated to deploy multiple identical virtual machines without manually repeating the OS installation process each time.

Changing the default administrator password prevents easy unauthorized access to printer settings, and restricting the management interface to internal access only prevents exposure to the public internet.

A fully modular power supply allows every cable, including the main motherboard cable, to be completely detached when not needed, offering the most cable management flexibility.

Since wired charging works fine, the battery and charging circuitry are functional, isolating the fault to the wireless charging coil itself, which handles inductive charging separately from the wired charging port.

An external USB optical drive lets a laptop without a built-in drive read from a physical DVD, allowing the software to be installed or its files copied over.

For workloads dominated by many simultaneous applications and browser tabs, having enough RAM capacity to hold everything in memory typically matters more than marginal differences in RAM speed.

Resistive touchscreens register physical pressure rather than relying on the skin's electrical properties, making them more reliable with gloved hands or a stylus, unlike standard capacitive touchscreens. Panel type (OLED vs LCD) is unrelated to touch-sensing technology.

A protocol analyzer captures and inspects packet contents for application-layer troubleshooting, a Wi-Fi analyzer surveys wireless spectrum conditions, a cable tester verifies wiring and continuity, and a toner probe traces unlabeled cable runs with an audible tone.

Cable internet has substantially lower latency than satellite, since satellite signals must travel to and from an orbiting satellite, adding significant round-trip delay that negatively affects real-time applications like competitive gaming.

Isolating IoT devices onto a separate network segment limits what a compromised device can reach, and keeping firmware updated patches known vulnerabilities, both directly reducing risk. Combining everything on one network, disabling the firewall, or reusing passwords would all increase risk instead.

A media converter converts electrical Ethernet signals into optical signals suitable for fiber transmission and back again at the far end, allowing a copper-based network to extend well beyond the 100-meter copper distance limit.

A DHCP reservation provides a consistent IP address tied to the printer's MAC address while keeping the address centrally managed on the DHCP server, making future changes easier than a static IP configured directly on the device.

A mesh Wi-Fi system uses multiple nodes that share a single SSID and coordinate to hand devices off seamlessly as they move through the home, unlike a single router, a single extender, or multiple separately named networks.

A VPN profile encrypts traffic between the device and the company's VPN gateway, allowing secure access to internal resources as if the device were on the office network.

Metal components in a case can interfere with the inductive coupling and alignment magnets used in wireless charging, causing inconsistent or failed charging even though the phone and pad both function normally otherwise.
