• Question 222:

  Which of the following is an email authentication method designed to detect email spoofing by attaching a digital signature to outgoing email?

  A. SPF
  B. DKIM
  C. DNS pointer
  D. MX records
  B. DKIM

  ---

  Explanation

  DKIM (DomainKeys Identified Mail) is an email authentication method that attaches a digital signature to outgoing emails to verify the email's authenticity and detect email spoofing.

  SPF (Sender Policy Framework): Specifies which mail servers are authorized to send emails for a domain but does not involve digital signatures.

  DNS Pointer (PTR): Used for reverse DNS lookups, not email authentication.

  MX Records: Specify mail servers for email delivery but do not authenticate emails.

• Question 223:

  Which of the following is used to verify the functionality of an Ethernet NIC?

  A. Toner probe
  B. Loopback plug
  C. Wi-Fi analyzer
  D. Punchdown tool
  B. Loopback plug

  ---

  Explanation

  A loopback plug is specifically designed to test whether a network interface card (NIC) can successfully transmit and receive signals at the physical/data-link level. For an Ethernet NIC, the loopback plug connects the transmit (TX) pins back to the receive (RX) pins on the NIC's port (or through an adapter), creating a closed circuit. When the NIC sends data, it should immediately "see" that data returned, confirming the NIC's port electronics and basic send/receive functionality are working. This is a direct, controlled test that helps isolate the problem: if the NIC fails the loopback test, the issue is likely the NIC/port/driver configuration rather than the cabling or network infrastructure.

  The other tools don't validate NIC function in this way: a toner probe traces and identifies cables, a Wi-Fi analyzer evaluates wireless networks (not wired Ethernet NICs), and a punchdown tool terminates wires into patch panels or keystone jacks. Therefore, the best CompTIA A+ answer for verifying an Ethernet NIC's functionality is a loopback plug.

• Question 224:

  A user is trying to print diagrams on 11in x 17in (28cm x 43cm) paper. The correct paper is in the printer, but the printer prompts the user to insert paper. A technician assisting the user successfully prints the diagram to a different printer that is the same model.

  Which of the following is the most likely cause of this issue on the user ' s printer?

  A. Tray settings
  B. Incorrect driver
  C. Connectivity issues
  D. Insufficient permissions
  A. Tray settings

  ---

  Explanation

  The most likely cause of this issue is incorrect tray settings on the user's printer. According to CompTIA Core 1 (220-1201) printer configuration and troubleshooting concepts, printers rely on tray configuration settings to determine the paper size and paper type loaded in each tray. If the tray is not configured for 11 x 17 (Tabloid /Ledger) paper, the printer will assume the required paper is unavailable-even if the paper is physically present.

  When a print job specifies a paper size that does not match the tray's configured settings, the printer commonly displays a message prompting the user to insert the correct paper. The fact that the same document prints successfully on another printer of the same model confirms that the driver, permissions, and connectivity are functioning correctly, further isolating the issue to the local printer's tray configuration.

  An incorrect driver would cause consistent problems across printers, not just one. Connectivity issues would prevent communication with the printer entirely, and insufficient permissions would generate access or authorization errors rather than a paper prompt.

  CompTIA emphasizes verifying tray assignments and paper size configuration as a primary troubleshooting step when printers incorrectly request paper that is already loaded.

• Question 226:

  A classroom projector, which is turned on, displays a flashing LED code but does not have any video output.

  Which of the following should a technician do to resolve the issue?

  A. Replace the bulb.
  B. Adjust the input resolution_
  C. Clean the air filter.
  D. Change the input source.
  A. Replace the bulb.

  ---

  Explanation

  If the lamp light is flashing orange or red, this usually means the lamp light is going to burn out soon or needs to be replaced

• Question 227:

  A technician is setting up a new SOHO wireless router.

  According to security best practices, which of the following should the technician do first?

  A. Enable encryption.
  B. Assign a static IP.
  C. Change the default password.
  D. Reset the router.
  C. Change the default password.

  ---

  Explanation

  The first security step after deploying a new router is to change the default administrative password. Default credentials are well known and pose a security risk if left unchanged.

  From CompTIA A+ 220-1101 Official Study Guide, Objective 2.3 -Secure a wireless network:

  "Always change default administrative credentials before further configuration to prevent unauthorized access."

• Question 228:

  A technician needs to select PC components with a minimal number of visible internal cables.

  Which of the following should the technician use?

  A. SATA drive connections
  B. Liquid cooling
  C. Modular power supply
  D. Wireless NIC
  C. Modular power supply

  ---

  Explanation

  A modular power supply allows a technician to connect only the power cables that are needed, reducing clutter and improving airflow. This is ideal when aiming for a clean build with minimal visible internal cables.

  Option A (SATA drive connections):Still require both power and data cables, adding to cable count.

  Option B (Liquid cooling):May reduce some bulk from large air coolers, but adds tubing and still needs cabling.

  Option D (Wireless NIC):Adds wireless capability but has no relation to internal cabling cleanliness.

• Question 229:

  A company updates its office with a new multifunction printer. Users report issues when they try to use scan-to-email functionality. The technician must ensure this feature is properly enabled.

  Which of the following should the technician do to resolve this issue?

  A. Adjust the SMTP server configurations for email.
  B. Check the printer ' s IP address configuration.
  C. Install the printer ' s driver software on all computers.
  D. Configure user authentication settings for email access.
  A. Adjust the SMTP server configurations for email.

  ---

  Explanation

  The correct answer is A. Adjust the SMTP server configurations for email.

  Scan-to-email functionality on a multifunction printer relies on proper configuration of an SMTP (Simple Mail Transfer Protocol) server. The printer must know how to send outgoing email, which requires settings such as:

  SMTP server address

  Port number (commonly 25, 465, or 587)

  Authentication credentials (username/password)

  Encryption method (SSL/TLS if required) If scan-to-email is not working, the most common cause is incorrect or missing SMTP configuration. Without this setup, the printer cannot send scanned documents via email.

  Why the other options are incorrect:

  B. Check the printer ' s IP address configuration This ensures network connectivity, but since the printer is already in use and the issue is specific to email functionality, IP configuration is unlikely the root cause.

  C. Install the printer ' s driver software on all computers Drivers are needed for printing from computers, but scan-to-email is handled directly by the printer and does not depend on client-side drivers.

  D. Configure user authentication settings for email access While authentication may be required in some setups, it is part of the broader SMTP configuration. The primary and most direct fix is ensuring SMTP settings are correct. Exam Tip (Core 1 220-1201): Scan-to-email issues # Check SMTP settings first Multifunction printers rely on network services (email protocols), not just drivers Final Answer:

  A. Adjust the SMTP server configurations for email
