💡 Hint

Common Mistakes

Omitting the dollar signs before variables.

Missing quotes or brackets around parts of the log format.

The correct log format uses variables with $ and includes quotes and brackets exactly as shown in option C.

💡 Hint

Common Mistakes

Swapping the order of file path and format name.

Using the default log file instead of the custom one.

The access_log directive takes the log file path first, then the log format name.

5fill in blank

hard

Fill all three blanks to create a conditional access log that logs only requests with status code 404.

Nginx

map $status $log_404 {
    default 0;
    [1] 1;
}

access_log [2] [3] if=$log_404;

Drag options to blanks, or click blank then click option'

A404

B/var/log/nginx/404.log

Cmain

D200

💡 Hint

Common Mistakes

Using the wrong status code in the map block.

Not using the if condition in access_log.

Mixing up the log file path and format name.

The map block sets $log_404 to 1 only when status is 404. The access_log directive uses this variable in the if condition to log only those requests.
