URL maps for routing in GCP - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a URL map that directs traffic to a backend service.

GCP

gcloud compute url-maps create my-url-map --default-service [1]

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

💡 Hint

Common Mistakes

Using an instance group instead of a backend service.

Confusing firewall rules or networks as routing targets.

The --default-service flag requires the name of a backend service to route traffic to. Using an instance group, firewall rule, or network is incorrect here.

medium

Complete the code to add a path matcher to the URL map for routing based on URL paths.

GCP

gcloud compute url-maps add-path-matcher my-url-map --default-service my-backend-service --path-matcher-name [1] --path-rules "/images/*=image-backend,/videos/*=video-backend"

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

Cpath-matcher-1

Durl-map

💡 Hint

Common Mistakes

Using reserved or generic names that do not identify the path matcher.

Confusing the path matcher name with backend service names.

The --path-matcher-name flag requires a custom name for the path matcher. 'path-matcher-1' is a valid descriptive name.

3fill in blank

hard

Fix the error in the command to create a URL map with a host rule.

GCP

gcloud compute url-maps create my-url-map --default-service my-backend-service --host-rules [1]

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

A"hosts=example.com,pathMatcher=path-matcher-1"

Bhosts=example.com,pathMatcher=path-matcher-1

C"host=example.com,pathMatcher=path-matcher-1"

Dhost=example.com,pathMatcher=path-matcher-1

💡 Hint

Common Mistakes

Not quoting the host rule string.

Using 'host' instead of 'hosts' in the key.

The --host-rules flag requires the value to be quoted and use the plural 'hosts' key. The correct format is a quoted string with 'hosts=' and 'pathMatcher=' keys.

4fill in blank

hard

Fill both blanks to define a URL map with a host rule and a path matcher.

GCP

gcloud compute url-maps create my-url-map --default-service [1] --host-rules "hosts=[2],pathMatcher=path-matcher-1"

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

Cmy-backend-service

Dtest.com

💡 Hint

Common Mistakes

Using a domain name as the default service.

Using an incorrect or unrelated hostname in the host rule.

The default service should be a backend service name like 'my-backend-service'. The host rule should specify the hostname, here 'example.com'.

5fill in blank

hard

Fill all three blanks to add a path matcher with path rules to an existing URL map.

GCP

gcloud compute url-maps add-path-matcher my-url-map --path-matcher-name [1] --default-service [2] --path-rules "/api/*=[3]"

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

Aapi-matcher

Bapi-backend

Cbackend-api

Ddefault-backend

Attempts:

💡 Hint

Common Mistakes

Using inconsistent backend service names between default and path rules.

Choosing generic or unrelated names for the path matcher.

The path matcher name should be descriptive like 'api-matcher'. The default service and the backend for the path rule should be the backend service handling API traffic, here 'api-backend'.
