CompTIA A+ Certification Exam: Core 1 220-1201 Prüfungsfragen mit Lösungen (Q188-Q193):

188. Frage
A financial institution needs a secure way to protect encryption keys used for unlocking chips on its credit cards. Which of the following should the institution use?

Antwort: B

Begründung:
A Hardware Security Module (HSM) securely manages cryptographic keys, including those used to protect credit card chips.


189. Frage
Which of the following display technologies is known for offering the highest contrast ratios?

Antwort: A

Begründung:
CompTIA A+ Core 1 (220-1201) display technology objectives emphasize that contrast ratio is strongly influenced by how well a screen can produce true black. OLED (Organic Light-Emitting Diode) panels are known for the highest contrast ratios because each pixel is self-emissive-meaning it generates its own light.
When an image requires black, OLED can turn individual pixels completely off, producing near-perfect black levels and extremely high (often "infinite") contrast in practical terms.
By comparison, LCD panels require a backlight, so black areas still allow some light leakage through the liquid crystal layer, reducing contrast. LED in this context is typically an LED-backlit LCD, not a fundamentally different pixel technology; it improves brightness and efficiency but still relies on backlighting, so contrast is limited by backlight bleed and panel design. QLED is also a type of LCD technology that uses a quantum dot layer to enhance color and brightness, but it still uses a backlight, so it cannot match OLED's per- pixel shutoff for black levels. Therefore, OLED is the best choice for the highest contrast ratios.


190. Frage
An IT specialist compares Bluetooth and NFC technologies for mobile device connectivity. Which of the following statements accurately describes a key difference between the two?

Antwort: C

Begründung:
NFC (Near-Field Communication)operates atvery short ranges - usually less than 4cm, and is ideal for quick, secure transactions like contactless payments.Bluetoothsupportslonger ranges (up to 10 meters or 32 feet)and is suited for ongoing connections like wireless headsets or file transfers.
Option A:Bluetooth is faster for large file transfers.
Option B:NFC usesless power, not more.
Option C:NFC doesnotrequire pairing - Bluetooth does.
CompTIA A+ Core 1 Exam Objective Reference:
Objective 1.5: Given a scenario, connect and configure accessories and ports of mobile devices.


191. Frage
An administrator has to enable automatic private IP reservations and assignments to a number of computers. Which of the following should the administrator use?

Antwort: A

Begründung:
DHCP automatically assigns IP configuration to client computers and supports reservations that consistently provide a specific IP address to a device based on its network adapter's MAC address.


192. Frage
A customer's laptop is no longer charging when plugged in to the docking station. A technician observes that none of the devices plugged in to the dock appear to be functioning. The technician verifies that the dock has power, the laptop ports are not damaged, and the BIOS updates are current, but the issue persists. Which of the following should the technician do next?

Antwort: A

Begründung:
Since the dock has power but none of its connected devices function, and other potential causes have been ruled out, the docking station itself is likely faulty. Replacing the dock resolves the hardware failure.
