Weighted round-robin in Nginx - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set up a basic upstream block for load balancing.

Nginx

upstream backend {
    server 192.168.1.1[1];
}

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

A:80 weight=5

B;

Cweight=5

D:80

💡 Hint

Common Mistakes

Adding weight without a space or without the port number

Using only weight without specifying port or semicolon

The correct syntax to specify a server with default settings is just the IP and optional port, like 192.168.1.1:80. Adding :80 specifies the port.

2fill in blank

medium

Complete the code to assign a weight of 3 to the server in the upstream block.

Nginx

upstream backend {
    server 192.168.1.2:80 [1];
}

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

Aweight=3

Bweight:3

Cweight 3

Dweight=5

💡 Hint

Common Mistakes

Using space instead of equals sign

Using colon instead of equals sign

Wrong weight number

In nginx, weights are assigned using weight=number syntax with an equals sign and no spaces.

3fill in blank

hard

Fix the error in the upstream block to correctly assign weights to two servers.

Nginx

upstream backend {
    server 192.168.1.3:80 weight=2;
    server 192.168.1.4:80 [1];
}

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

Aweight 3

Bweight= 3

Cweight=3

Dweight:3

Attempts:

💡 Hint

Common Mistakes

Missing semicolon at end of server line

Using space or colon instead of equals sign

Each server line must end with a semicolon. Also, weight assignment uses weight=number with no spaces after equals.

4fill in blank

hard

Fill both blanks to create an upstream block with two servers having weights 4 and 6.

Nginx

upstream backend {
    server 192.168.1.5:80 [1];
    server 192.168.1.6:80 [2];
}

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

Aweight=4

Bweight=6

C;

Dweight=5

Attempts:

3 left

💡 Hint

Common Mistakes

Using wrong weight numbers

Missing semicolons

Using incorrect syntax for weight

Each server line must specify the weight with weight=number and end with a semicolon.

5fill in blank

hard

Fill all three blanks to configure an upstream with weighted round-robin load balancing.

Nginx

upstream backend {
    [1] 192.168.1.7:80 [2];
    [3] 192.168.1.8:80 weight=7;
}

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

Aserver

Bweight=5

Dweight=3

Attempts:

3 left

💡 Hint

Common Mistakes

Omitting the 'server' keyword

Incorrect weight syntax

Missing semicolons

Each server line starts with server. The first server has weight 5, the second weight 7. Weighted round-robin is the default when weights are specified.
