• Question 972:

  A technician is connecting a hands-free car system via Bluetooth.

  Which of the following is a security feature that should be used for this task?

  A. BitLocker
  B. Biometrics
  C. TPM
  D. PIN code
  D. PIN code

  ---

  Explanation

  When connecting a Bluetooth device like a hands-free car system, using a PIN code adds a layer of security. The PIN code must be entered or confirmed during the pairing process to ensure that the connection is authorized and secure.

  D.

  PIN code: Provides an additional security measure during Bluetooth pairing to prevent unauthorized access.

  Why the other options are incorrect:

  BitLocker: BitLocker is a drive encryption feature used to secure data on hard drives, not for securing Bluetooth connections.

  Biometrics: Biometrics refers to authentication using physical traits like fingerprints, which are not typically used for Bluetooth connections. TPM: Trusted Platform Module (TPM) is a hardware security feature used for encryption and secure boot processes, not for Bluetooth pairing.

  This falls under the Mobile Devices and Security domain in the CompTIA A+ Core 1 exam.

• Question 973:

  Auser is unable to perform contactless payments with a phone. Which of the following functions is MOST likely causing the issue?

  A. NFC
  B. Hotspot
  C. Bluetooth
  D. USB
  A. NFC

  ---

  Explanation

  Near field communication (NFC) is a function that enables contactless payments with a phone by allowing it to communicate with compatible devices within close proximity. If NFC is not working properly, the user will not be able to perform contactless payments with the phone. Hotspot is a feature that allows a device to share its internet connection with other devices via Wi-Fi, Bluetooth, or USB. Bluetooth is a wireless technology that allows devices to connect and exchange data over short distances. USB is a standard interface that connects devices such as keyboards, mice, flash drives, etc

• Question 974:

  Which of the following is designed to be used in commercial spaces?

  A. USB 3.1 Gen 2
  B. Straight tip fiber connector
  C. Plenum cabling
  D. Cat 8
  C. Plenum cabling

  ---

  Explanation

  Plenum cabling is designed for use in commercial spaces where cables run through air ducts or plenum spaces, as it has fire-resistant properties and emits less toxic smoke.

  Why Not A (USB 3.1 Gen 2): USB is for peripheral connections, not large-scale commercial installations.

  Why Not B (Straight tip fiber connector): Fiber connectors are for high-speed connections but are not specifically for commercial spaces.

  Why Not D (Cat 8): While Cat 8 is high-speed, it is not uniquely suited for commercial spaces like plenum cabling.

  Core 1 (220-1101), Section 3.1, cabling standards.

• Question 975:

  A technician needs to upgrade the power supply of a workstation that contains a high-end graphics card, 16 hyperthreaded cores, and multiple hard drives. Which of the following should the technician use to determine the appropriate power supply for the workstation?

  A. The manufacturer's specifications for the components
  B. The wattage of the current power supply
  C. The wattage of the motherboard
  D. The capacity of the hard drives
  E. The number of hyperthreaded cores
  A. The manufacturer's specifications for the components

  ---

  Explanation

  The manufacturer's specifications for the components are the best source of information to determine the appropriate power supply for the workstation. The manufacturer's specifications will list the power requirements and recommendations for each component, such as the graphics card, the CPU, the hard drives, and the motherboard. By adding up the power consumption of each component, the technician can estimate the total wattage needed for the workstation. The technician should also consider some extra headroom for future upgrades or peak loads. The technician can then choose a power supply that meets or exceeds the total wattage and has the right connectors and form factor for the workstation.

• Question 976:

  New memory modules were installed in several Windows desktops but some users are still reporting performance issues. Upon investigation, a systems administrator notices the desktop has not recognized the new memory modules. Which of the following should the systems administrator perform to help resolve this issue?

  A. Configure appropriate settings within the BIOS
  B. Replace the RAM
  C. Modify the boot. ini file.
  D. Install the required drivers through the Control Panel
  A. Configure appropriate settings within the BIOS

  ---

  Explanation

  To resolve the issue of new memory modules not being recognized, the systems administrator should configure appropriate settings within the BIOS. This can include enabling memory mapping or setting memory speed and timings.

  References:

  CompTIA A+ Certification Exam Objectives, 220-1001 Section 1.8 Configure appropriate settings within the BIOS. If new memory modules were installed in several Windows desktops but some users are still reporting performance issues and

  the desktop has not recognized the new memory modules, the systems administrator should configure appropriate settings within the BIOS to help resolve this issue.

• Question 977:

  Whish of the following is the BEST RAM type for the technician to retrieve?

  A. SoDIMM
  B. DDR4
  C. Single channel
  D. ECC
  B. DDR4

• Question 980:

  A user's desktop computer is connected via an Ethernet cable and often drops the connection. When the computer does connect, the network speeds are normal. No other network users on the same floor are reporting issues. The administrator verified that all authentication systems are working as intended and the Ethernet cable was replaced. Which of the following is the most likely cause of the issue?

  A. Slow network speeds
  B. Port flapping
  C. Limited connectivity
  D. 802.1X configuration
  B. Port flapping

  ---

  Explanation

  Port flapping, also known as link flapping, is a network issue that causes a switch port's state to fluctuate between up and down within short periods of time. This instability affects network connectivity and performance. Port flapping can be caused by various factors, such as faulty cables, hardware issues, configuration issues, or other network issues12. In this scenario, the user's desktop computer is connected via an Ethernet cable and often drops the connection, while no other network users on the same floor are reporting issues. The administrator verified that all authentication systems are working as intended and the Ethernet cable was replaced. Therefore, the most likely cause of the issue is port flapping on the switch port that connects to the user's computer. References
