Keepalive connections in Nginx - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to enable keepalive connections in the upstream block.

Nginx

upstream backend {
    server backend1.example.com;
    [1] 32;
}

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

💡 Hint

Common Mistakes

Using 'proxy_pass' inside the upstream block instead of 'keepalive'.

Confusing 'listen' directive with keepalive settings.

The keepalive directive inside the upstream block sets the number of idle keepalive connections to upstream servers.

Complete the code to enable keepalive connections in the proxy settings.

Nginx

location / {
    proxy_pass http://backend;
    proxy_http_version 1.1;
    [1] 100;
}

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

💡 Hint

Common Mistakes

Using 'proxy_keepalive' which is not a valid directive.

Confusing 'keepalive_timeout' with enabling keepalive requests.

The keepalive_requests directive enables keepalive connections by specifying how many requests can be sent over a single keepalive connection.

Fix the error in the keepalive timeout configuration.

Nginx

keepalive_timeout [1] 20s;

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

💡 Hint

Common Mistakes

Using 'on' which is invalid for keepalive_timeout.

Using 'keepalive' or 'proxy' which are not valid values here.

The keepalive_timeout directive accepts a time value or 'off' to disable it. Using 'off' disables keepalive timeout.

4fill in blank

hard

Fill both blanks to configure upstream keepalive connections and proxy settings correctly.

Nginx

upstream backend {
    server backend1.example.com;
    [1] 64;
}

location / {
    proxy_pass http://backend;
    proxy_http_version 1.1;
    [2] 100;
}

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

Akeepalive

Bkeepalive_requests

Cproxy_set_header

Dkeepalive_timeout

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing 'keepalive_timeout' with 'keepalive_requests'.

Using 'proxy_set_header' instead of keepalive directives.

The keepalive directive in the upstream block sets the number of idle keepalive connections. The keepalive_requests directive sets how many requests can be sent over one keepalive connection.

5fill in blank

hard

Fill all three blanks to configure keepalive connections with timeout and request limits.

Nginx

upstream backend {
    server backend1.example.com;
    [1] 32;
}

location / {
    proxy_pass http://backend;
    proxy_http_version 1.1;
    [2] 100;
    [3] 75s;
}

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

Akeepalive

Bkeepalive_requests

Ckeepalive_timeout

Dproxy_set_header

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'proxy_set_header' instead of keepalive directives.

Confusing 'keepalive_timeout' with 'keepalive_requests'.

The keepalive directive sets idle connections in upstream. keepalive_requests limits requests per keepalive connection. keepalive_timeout sets the timeout for keepalive connections.
