Round-robin (default) in Nginx - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to define an upstream block using the default round-robin method.

Nginx

upstream backend {
    server [1];
}

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

💡 Hint

Common Mistakes

Trying to specify 'round_robin' explicitly inside the upstream block.

The server directive inside the upstream block defines backend servers. The default load balancing method is round-robin, so just listing servers is enough.

Complete the code to proxy requests to the upstream group named 'backend'.

Nginx

    proxy_pass http://[1];
}

💡 Hint

Common Mistakes

Using an IP address instead of the upstream group name.

The proxy_pass directive should point to the upstream group name to use round-robin load balancing.

3fill in blank

hard

Fix the error in the upstream block by completing the missing server address.

Nginx

upstream backend {
    server [1];
    server 192.168.1.11:80;
}

💡 Hint

Common Mistakes

Putting parameters like 'weight=3' instead of an IP address.

Each server directive must have a valid IP address and port. Here, the first server address was missing.

4fill in blank

hard

Fill both blanks to create an upstream block with two servers using default round-robin.

Nginx

upstream backend {
    server [1];
    server [2];
}

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

💡 Hint

Common Mistakes

Using parameters instead of server addresses in server directives.

Both blanks must be valid server addresses. Parameters like 'weight=5' or 'ip_hash' are not server addresses.

5fill in blank

hard

Fill all three blanks to create a proxy_pass directive inside location that uses the 'backend' upstream group.

Nginx

location /app/ {
    proxy_pass http://[1]/[2];
    proxy_set_header Host [3];
}

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

C$host

Dlocalhost

💡 Hint

Common Mistakes

Using 'localhost' instead of the upstream group name.

Not forwarding the original host header.

The proxy_pass should point to the upstream group 'backend' and the correct URI path. The proxy_set_header Host should pass the original host header using $host.
