To verify the source of printer misuse, the administrator needs detailed records showing who performed specific actions and when. According to CompTIA Core 1 (220-1201) printer management and security objectives, audit logs provide a historical record of printer activity, including user IDs, timestamps, document names, and print volumes. These logs allow administrators to trace printer usage back to a specific user or device, making them the most effective tool for investigating misuse.

Secure printing requires users to authenticate at the printer before jobs are released, which helps prevent unauthorized access but does not provide historical evidence of past misuse. A print counter tracks the total number of pages printed but does not identify individual users or specific print jobs. User authentication ensures that only authorized users can access the printer, but by itself it does not provide detailed usage tracking unless combined with logging.

CompTIA emphasizes audit logging as a critical component of accountability and security across systems, including printers. When investigating policy violations or misuse, audit logs are the primary source of verifiable evidence.

DNS contains different record types that serve specific purposes. To determine where incoming email should be delivered for a particular domain, DNS uses an MX (Mail Exchange) record. CompTIA A+ identifies MX records as essential for routing mail from external senders to the appropriate mail server assigned to a domain.

The MX record specifies:

The mail server hostname responsible for receiving messages

Priority values, which determine which server to try first

The server destination for SMTP traffic

When someone sends an email, the sending mail server queries DNS to find the MX record for the recipient’s domain. The SMTP server then relays the email to the server listed in that record.

CNAME is used for aliasing hostnames, TXT is used for verification/security (SPF, DKIM), and AAAA maps a hostname to an IPv6 address. None of these direct email delivery. Only MX records are designed to instruct mail servers where to deliver incoming email.

Thus, the correct answer is MX.

A DHCP reservation ensures a specific device always receives the same IP address from the DHCP server whenever it requests an address. The reservation is typically created by associating the device’s MAC address with a chosen IP address inside the DHCP scope. When that device connects and performs the DHCP process, the server recognizes the MAC address and offers the reserved IP instead of assigning the next available dynamic address. This is commonly used for devices that benefit from consistent addressing (for example, printers, servers, or network appliances) while still centrally managing addressing through DHCP rather than configuring a manual static IP on the endpoint.

An exclusion is the opposite idea: it defines a range of IP addresses within a scope that the DHCP server will not hand out (often because those addresses are used for statically assigned devices). A lease is the time period that a dynamically assigned IP address is valid before it must be renewed; it does not guarantee the same IP every time. A scope is the overall pool/range of IP addresses and DHCP options (gateway, DNS, etc.) available for a given subnet. Therefore, the component that guarantees the same IP is a reservation.

NTP (Network Time Protocol) is specifically designed to synchronize the clocks of networked computers and devices automatically.

From CompTIA A+ 220-1101 Official Study Guide, Objective 2.6 – Network services and protocols:

“NTP is used to automatically synchronize system clocks on network devices, ensuring all systems have accurate time.”
