• Question 931:

  A customer wants to archive a large number of photos and does not plan to retrieve them often. The customer wants a storage option that is the least expensive per gigabyte. Which of the following should the technician suggest?

  A. NVMe SSD
  B. SCSI RAID
  C. 15,000rpm SAS
  D. 5,400rpm HOD
  D. 5,400rpm HOD

  ---

  Explanation

  The correct answer is

  D. 5,400rpm HDD. A 5,400rpm HDD (Hard Disk Drive) is a type of storage device that uses spinning magnetic disks to store data. A 5,400rpm HDD is the least expensive per gigabyte among the options given, as it has a lower rotational speed and performance than other types of HDDs or SSDs (Solid State Drives). A 5,400rpm HDD is suitable for archiving a large number of photos that are not accessed frequently, as it can offer high capacity and reliability at a low cost. the average cost per gigabyte of a 5,400rpm HDD is around $0.02 to $0.0312, while the average cost per gigabyte of the other options are: NVMe SSD: $0.10 to $0.1534 SCSI RAID: $0.20 to $0.305 15,000rpm SAS: $0.30 to $0.40 Therefore, a 5,400rpm HDD is the cheapest option among the four.

• Question 932:

  Which of the following wireless technologies is used by mobile devices to process payments at kiosks?

  A. Wi-Fi 6
  B. Bluetooth
  C. NFC
  D. RFID
  C. NFC

  ---

  Explanation

  NFC stands for near-field communication, which is a wireless technology that allows two devices to exchange data when they are in close proximity (usually within a few centimeters). NFC is commonly used by mobile devices to process payments at kiosks, such as Apple Pay or Google Pay. Wi-Fi 6 is a wireless standard that provides faster speed and lower latency than previous versions of Wi-Fi. Bluetooth is a wireless technology that allows devices to communicate over short distances (usually within 10 meters). RFID stands for radio-frequency identification, which is a wireless technology that uses radio waves to identify and track objects that have RFID tags attached to them

• Question 933:

  A user reports that a computer has a virus on it. Which of the following is the FIRST step the technician should take?

  A. Determine a plan of action to resolve the problem.
  B. Run antivirus software to remove the virus from the computer.
  C. Ask the user about the symptoms the computer is experiencing.
  D. Make a backup of the user's data on an external drive.
  C. Ask the user about the symptoms the computer is experiencing.

  ---

  Explanation

  Asking the user about the symptoms the computer is experiencing is the first step the technician should take when a user reports that a computer has a virus on it. This step helps the technician to gather information and identify the problem before determining a plan of action to resolve it. Running antivirus software, making a backup of the user's data, or determining a plan of action are not the first steps, but possible actions that can be taken after identifying the problem.

• Question 934:

  Which of the following components houses the MX record?

  A. DNS
  B. VLAN
  C. DHCP
  D. SMTP
  A. DNS

  ---

  Explanation

  The domain name system (DNS) is the component that houses the MX record. The MX record is a type of DNS record that specifies which mail server is responsible for receiving email messages for a domain name. VLAN is an acronym for virtual local area network, which is a logical subdivision of a network that allows devices to communicate as if they were on the same physical segment. DHCP is an acronym for dynamic host configuration protocol, which is a network protocol that assigns IP addresses and other configuration parameters to devices on a network automatically. SMTP is an acronym for simple mail transfer protocol, which is a network protocol that allows sending and receiving email messages over TCP/IP networks

• Question 935:

  A user is unable to access secure applications on their tablet when working from home a couple days per week, but the applications work when in the office. Which of the following services most likely needs to be reconfigured to allow for remote work?

  A. Global Positioning System
  B. Mobile device management
  C. Wi-Fi Protected Access
  D. Near-field communication
  B. Mobile device management

  ---

  Explanation

• Question 936:

  A customer is reporting that some of the keys at the bottom edge on a laptop are hard to press and the track pad buttons require significant force to click. The technician inspects the laptop and does not notice any cracks or other damage to the chassis or screen. Which of the following is the most likely cause of the issue?

  A. The customer dropped the laptop.
  B. The digitizer has failed.
  C. The battery is swollen.
  D. An open bottle of rubbing alcohol fell onto the keyboard.
  C. The battery is swollen.

  ---

  Explanation

  A swollen battery is the most likely cause of the issue that the customer is reporting. A swollen battery is a battery that has expanded in size due to a chemical reaction, gas buildup, or overheating. A swollen battery can cause pressure on the laptop's chassis, keyboard, track pad, and other components, making them hard to press or click. A swollen battery can also pose a fire hazard and damage the laptop's performance and lifespan. The other options are not as likely or relevant to the issue. Dropping the laptop may cause cracks or other visible damage to the chassis or screen, but the technician did not notice any. The digitizer is the part of the laptop that converts touch input into digital signals, and it has nothing to do with the keyboard or the track pad buttons. An open bottle of rubbing alcohol falling onto the keyboard may cause liquid damage, corrosion, or short circuits, but it would not affect the track pad buttons or the bottom edge of the keyboard. To troubleshoot and resolve the issue, the technician should remove the battery from the laptop and inspect it for signs of swelling, such as bulging, deformation, or leakage. The technician should also check the laptop's chassis, keyboard, and track pad for any signs of damage or warping caused by the battery. The technician should then replace the swollen battery with a new one that is compatible with the laptop's model and specifications. The technician should also dispose of the swollen battery properly and safely, following the local regulations and guidelines.

• Question 937:

  Which of the following network services is used to assign an IP address to a network host?

  A. DHCP
  B. DNS
  C. LDAP
  D. SMTP
  A. DHCP

  ---

  Explanation

  DHCP (Dynamic Host Configuration Protocol) is the service used to automatically assign IP addresses to network hosts. It dynamically manages the distribution of IP addresses and configuration details (like subnet mask, gateway, and DNS servers), ensuring no two devices are assigned the same address on the network.

  Option B (DNS): Incorrect. DNS translates domain names into IP addresses but does not assign them.

  Option C (LDAP): Incorrect. LDAP is a protocol used for accessing and maintaining directory services, such as user information and permissions.

  Option D (SMTP): Incorrect. SMTP is used for sending and receiving email, not for IP address assignment.

• Question 938:

  Which of the following types of connectors does an IDE hard drive use for power?

  A. F type
  B. SC
  C. Molex
  D. Lightning
  C. Molex

  ---

  Explanation

  An IDE hard drive uses a Molex connector for power. This 4-pin connector is a standard for older drives.

  Why Not A (F type): F type connectors are used for coaxial cables in video and internet applications.

  Why Not B (SC): SC connectors are for fiber optic cables.

  Why Not D (Lightning): Lightning connectors are for Apple devices.

• Question 939:

  A technician is working on a RAID 1 array that is apparently degraded. The technician verifies the RAM and power are both operating as expected. Which of the following can the technician do to further isolate the issue?

  A. Perform individual drive diagnostics.
  B. Run the chkdsk /i command.
  C. Rebuild the RAID array.
  D. Reconfigure the array as RAID 0.
  A. Perform individual drive diagnostics.

• Question 940:

  A technician is setting up a workstation to use FTP.

  Which of the following ports does the technician need to enable?

  A. 20
  B. 23
  C. 53
  D. 68
  A. 20

  ---

  Explanation

  Port 20 is used for FTP data transfer (along with port 21 for control), so enabling this port is required. Ports 23, 53, and 68 are unrelated to FTP functionality, as they correspond to Telnet, DNS, and DHCP respectively. CompTIA A+ Core 1 objectives outline the importance of knowing standard port numbers for network services.
