When examining the log files from a Windows IIS Web Server, how often is a new log file created?

Question

Options

• Athe same log is used at all times
• Ba new log file is created everyday
• Ca new log file is created each week
• Da new log is created each time the Web Server is started

• A
  9% (4)
• B
  87% (40)
• C
  2% (1)
• D
  2% (1)

Explanation

By default, IIS (Internet Information Services) creates a new log file each day, named using the date format (e.g., u_ex260511.log), making it easy to locate activity from a specific date. Option A is wrong because using a single log file indefinitely would make it unmanageable and difficult to parse. Option C is incorrect because weekly rotation is not the IIS default, though it can be configured. Option D is wrong because IIS log rotation is time-based, not event-based - restarting the web server does not trigger a new log file.

Memory tip: Think of IIS logs like a daily diary - one new entry (file) per day, stored in C:\inetpub\logs\LogFiles\ by default. The "W3C" log filename embeds the date, so the daily cadence is baked right into the filename format.
