Page 928 "When IIS records the logs in the W3C Extended Log Format, the IIS stores all the logged events in the GMT format, instead of the format of the local time zone for the system. This point must be considered during the examination of the logs because IIS creates a new log file for the next day at midnight in GMT. "

In a Windows IIS web server, a new log file is created on a daily basis. Therefore, the correct answer is B. Explanation: When IIS logging is enabled, the web server writes log files that contain information about the requests processed by the server. These log files are typically used for troubleshooting, performance monitoring, and security auditing. In a default IIS installation, the web server generates a new log file each day, with the file name format of "u_exYYMMDD.log", where YYMMDD represents the year, month, and day of the log file. For example, the log file for March 25, 2023, would be named "u_ex230325.log". The log files are stored in the W3SVC folder under the Windows system root directory (e.g., C:\Windows\System32\LogFiles\W3SVC). Therefore, the correct answer is B, a new log file is created every day.
