💡 Hint

Common Mistakes

Using 'off' or 'disable' instead of 0 disables logging incorrectly.

Setting 404 to 1 will enable logging instead of disabling it.

Setting the value to 0 disables logging for status 404.

Complete the code to use the variable $loggable to control access log.

Nginx

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

A$loggable

B$request_method

C$status

D$remote_addr

💡 Hint

Common Mistakes

Using $status directly in the 'if' condition does not work as expected.

Using unrelated variables like $request_method or $remote_addr.

The 'if' parameter uses the $loggable variable to conditionally enable logging.

hard

Fix the error in the map block to correctly disable logging for 500 errors.

Nginx

map $status $loggable {
    500 [1];
    default 1;
}

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

Bfalse

Cdisable

D0

💡 Hint

Common Mistakes

Using 'off' or 'disable' causes configuration errors.

Using 'false' is not recognized by nginx in map.

Only 0 disables logging correctly in the map block; 'off', 'disable', or 'false' are invalid.

4fill in blank

hard

Fill both blanks to log only POST requests with status 200.

Nginx

map "$request_method:$status" $loggable {
    "[1]:[2]" 1;
    default 0;
}

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

BGET

C200

D404

3 left

💡 Hint

Common Mistakes

Using 'GET' instead of 'POST' will log wrong requests.

Using '404' instead of '200' will log wrong status.

The map matches 'POST:200' to enable logging only for POST requests with status 200.

5fill in blank

hard

Fill all three blanks to log requests from 192.168.1.1 with status 403 or 404.

Nginx

map "$remote_addr:$status" $loggable {
    "[1]:[2]" 1;
    "[1]:[3]" 1;
    default 0;
}

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

A192.168.1.1

B403

C404

D200

Attempts:

3 left

💡 Hint

Common Mistakes

Using different IPs for the two entries.

Using status 200 instead of 403 or 404.

The map enables logging for IP 192.168.1.1 with status 403 or 404 only.
