Which log type is described as a comma-delimited text file containing entries with fields such as ID, Date, Time, Description, IP Address, Host Name, and MAC Address?

• A. DNS Logs
• B. System Event Logs
• C. Application Logs
• D. DHCP Server Logs

Answer: (D)

This question tests your ability to recognize log types by the information they record. DHCP server logs are meant to track IP address assignments and the devices that received them, so they’re commonly stored as plain-text, comma-delimited files where each entry includes an identifier, date, time, a description of the event, the assigned IP address, the device’s host name, and the device’s MAC address. That combination—time-stamped lease events with both IP and MAC addresses along with a host name—is characteristic of DHCP activity, since DHCP manages who gets which IP on the network and records the client’s hardware address for reference. Other log types don’t fit this particular data set as neatly. DNS logs center on domain name lookups and responses, not on DHCP lease details like MAC addresses. System and application logs capture a broader range of events from the operating system or software, typically focusing on event IDs, sources, and messages rather than a consistent set of network lease fields like MAC address alongside IP and host name.
