In Windows IIS Web Server logs, how often is a new log file created?

• A. A New Log File Is Created Every Day
• B. A New Log File Is Created Each Week
• C. The Same Log Is Used At All Times
• D. A New Log Is Created Each Time The Web Server Is Started

Answer: (A)

IIS creates log files on a rollover schedule, and the typical default is daily. This means each calendar day gets its own log file, making it easy to archive and analyze a single day’s activity. You’ll often see the log file name include the date, so you can quickly tell which day the entries belong to. You can change this rollover setting in the IIS Manager under the site’s Logging feature; the available options generally include Daily, Hourly, Weekly, or Monthly. Daily is the standard default because it offers a good balance between file size and manageability. A weekly or monthly rollover would group more data into fewer files, making per-day analysis harder, while a rollover only on server start would miss activity between restarts.
