Practice - 5 Tasks

Complete the code to enable gzip compression in nginx.

Nginx

gzip [1];

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

💡 Hint

Common Mistakes

Using 'off' disables compression.

Using 'disable' or 'enable' are invalid values.

Setting gzip on; enables gzip compression in nginx, which reduces file sizes sent to clients.

Complete the code to set the Content-Encoding header for gzip compressed responses.

Nginx

add_header Content-Encoding [1];

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

A"deflate"

B"identity"

C"compress"

D"gzip"

💡 Hint

Common Mistakes

Using 'deflate' or 'compress' when gzip is enabled.

Using 'identity' disables encoding.

The Content-Encoding header should be set to "gzip" to indicate gzip compression.

Fix the error in the gzip_types directive to compress CSS and JavaScript files.

Nginx

gzip_types [1];

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

Atext/css application/javascript

Btext/css; application/javascript

Ctext/css, application/javascript

Dtext/css application/javascript;

💡 Hint

Common Mistakes

Using commas or semicolons between MIME types.

Adding trailing semicolons inside the directive value.

The gzip_types directive expects space-separated MIME types without commas or semicolons.

4fill in blank

hard

Fill both blanks to set caching headers for static files to optimize delivery.

Nginx

location /static/ {
    expires [1];
    add_header Cache-Control "[2]";
}

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

A30d

Bmax-age=2592000

Cno-cache

Dno-store

💡 Hint

Common Mistakes

Using 'no-cache' or 'no-store' disables caching.

Mixing commas or wrong syntax in directives.

Setting expires 30d; and Cache-Control "max-age=2592000"; tells browsers to cache static files for 30 days, improving load speed.

5fill in blank

hard

Fill all three blanks to configure gzip compression with minimum file size and buffer settings.

Nginx

gzip on;
gzip_min_length [1];
gzip_buffers [2] [3];

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

A1000

B4

C8k

D1024

💡 Hint

Common Mistakes

Using buffer size without unit.

Setting gzip_min_length too low or too high.

gzip_min_length 1000; sets minimum file size to compress. gzip_buffers 4 8k; sets buffer count and size for compression.
