• Question 361:

  A sales team user is attending a conference and wants a mobile device that allows the user to quickly collect contact information from as many potential leads as possible. Which of the following connection methods should a technician configure for the user?

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

  ---

  Explanation

  Near Field Communication (NFC) is the most appropriate connection method for the user's need to quickly collect contact information. NFC enables short-range communication between compatible devices by bringing them close together or tapping them. This feature is ideal for exchanging contact information or transferring small amounts of data rapidly and conveniently, making it perfect for a sales environment at a conference.

• Question 364:

  A technician installed a high-end graphics card in a desktop, and now, the desktop randomly shuts down during operations. Which of the following should the technician do next?

  A. Confirm the power supply is grounded.
  B. Check the power supply wattage rating.
  C. Check whether the power supply is redundant.
  D. Confirm the power cables are well connected.
  B. Check the power supply wattage rating.

  ---

  Explanation

  The correct answer is

  B. Check the power supply wattage rating. A possible cause of the desktop randomly shutting down during operations is that the power supply is not able to provide enough power for the high-end graphics card. The power consumption of today's graphics cards has increased a lot, and the top models demand between 110 and 270 watts from the power supply1. Therefore, the technician should check the power supply wattage rating and make sure it is sufficient for the graphics card and the rest of the components. Confirming the power supply is grounded, checking whether the power supply is redundant, or confirming the power cables are well connected are not likely to solve this problem.

• Question 365:

  Which of the following commonly uses NFC?

  A. Contactless payments
  B. loT devices
  C. Inventory tracking
  D. Tethering
  A. Contactless payments

  ---

  Explanation

  Contactless payments commonly use NFC (Near Field Communication) technology. NFC allows two devices to communicate wirelessly when they are brought close together, typically within a few centimeters. Contactless payment systems, such as Apple Pay, Google Wallet, and Samsung Pay, use NFC to securely transmit payment information between a smartphone or smartwatch and a payment terminal. While IoT devices, inventory tracking, and tethering may also use NFC, contactless payments are the most common use case.

• Question 366:

  A technician needs to install a printer on the network. Which of the following must the technician configure? (Choose three.)

  A. PCL
  B. Dots per inch
  C. Gateway
  D. Subnet mask
  E. MAC address
  F. IMEI
  G. IP address
  H. Drivers
  C. Gateway
  D. Subnet mask
  G. IP address

  ---

  Explanation

  When installing a printer on a network, the technician needs to configure the network settings, which include the IP address, subnet mask, and gateway. These settings are used to ensure that the printer can communicate with other devices on the network. When installing a printer on a network, the technician must configure the network settings of the printer to ensure that it can communicate with other devices on the network. This includes configuring the gateway, subnet mask and IP address of the printer. The gateway is the device that connects the local network to other networks or the Internet. The subnet mask is used to determine which part of an IP address represents the network and which part represents individual hosts on that network. The IP address is a unique identifier for each device on a network.

• Question 367:

  A user reported performance issues on a computer after a recent OS update. A technician is confident that rolling back the system will resolve the issue. Which of the following steps should the technician take next?

  A. Document the findings.
  B. Perform a system backup.
  C. Initiate the system restore.
  D. Verify full system functionality.
  B. Perform a system backup.

  Which of the following DNS record types is used to direct email to a mail server?

  A. CNAME
  B. SRV
  C. MX
  D. SOA

  ---

  Explanation

  An MX (Mail Exchange) record specifies the mail server responsible for receiving email for a domain.

  Why Not A (CNAME): CNAME is used for domain aliasing, not for email delivery.

  Why Not B (SRV): SRV records are used to locate specific services, not mail servers.

  Why Not D (SOA): SOA records provide domain information but do not handle email.
