easy

💡 Hint

Common Mistakes

Omitting the trailing slash in proxy_pass causes incorrect URL forwarding.

Using the wrong version path in proxy_pass.

The proxy_pass directive must include the trailing slash to correctly forward the URI after /api/v1/.

Complete the code to route requests to version 2 of the API.

Nginx

    proxy_pass http://backend[1];
}

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

A/v1/

B/v3/

C/v2/

💡 Hint

Common Mistakes

Using the wrong version number in proxy_pass.

Missing the trailing slash in proxy_pass.

Requests to /api/v2/ should be proxied to the backend's /v2/ path with a trailing slash.

Fix the error in the location block to correctly route to version 1 API.

Nginx

location /api/v1 {
    proxy_pass http://backend[1];
}

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

A/v2/

B/v1

C/

D/v1/

💡 Hint

Common Mistakes

Missing trailing slash in location causes partial matching issues.

proxy_pass without trailing slash changes the forwarded URI.

The location block must end with a slash to match the path correctly, and proxy_pass must include the trailing slash.

4fill in blank

hard

Fill both blanks to route requests to version 3 API and set a custom header.

Nginx

location /api/v3/ {
    proxy_pass http://backend[1];
    proxy_set_header X-API-Version [2];
}

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

A/v3/

B"v3"

C"v2"

D/v2/

💡 Hint

Common Mistakes

Using wrong version path in proxy_pass.

Setting header without quotes causing syntax errors.

The proxy_pass must point to /v3/ to route correctly, and the header should reflect the API version "v3".

5fill in blank

hard

Fill all three blanks to create a map for API version routing and use it in proxy_pass.

Nginx

map $uri $backend_path {
    ~^/api/v1/ /v1/;
    ~^/api/v2/ /v2/;
    default [1];
}

location /api/ {
    proxy_pass http://backend[2];
    proxy_set_header X-API-Version [3];
}

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

A/v3/

B$backend_path

C"dynamic"

D/default/

Attempts:

3 left

💡 Hint

Common Mistakes

Not using the map variable in proxy_pass.

Incorrect default path causing routing errors.

Missing quotes around header value.

The default path in the map is /v3/ for other versions, proxy_pass uses the mapped variable $backend_path, and the header is set to "dynamic" to indicate dynamic routing.
