Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the protocol used by the HTTP(S) Load Balancer.

GCP

load_balancer = compute.loadBalancers().insert(project=project_id, body={"protocol": "[1]"})

Common Mistakes

Choosing TCP or UDP which are Layer 4 protocols.

The HTTP(S) Load Balancer uses the HTTP protocol at Layer 7 to route requests.

Complete the code to define the backend service for the HTTP(S) Load Balancer.

GCP

backend_service = compute.backendServices().insert(project=project_id, body={"name": "my-backend", "protocol": "[1]"})

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

💡 Hint

Common Mistakes

Using TCP or UDP which are Layer 4 protocols.

The backend service for an HTTP(S) Load Balancer must use the HTTP protocol to handle Layer 7 traffic.

3fill in blank

hard

Fix the error in the URL map configuration for routing HTTP requests.

GCP

url_map = compute.urlMaps().insert(project=project_id, body={"defaultService": "[1]"})

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

💡 Hint

Common Mistakes

Using underscores or hyphens instead of camelCase.

The correct key for specifying the backend service in a URL map is 'backendService' in camelCase.

4fill in blank

hard

Fill both blanks to create a health check configuration for the HTTP(S) Load Balancer.

GCP

health_check = compute.healthChecks().insert(project=project_id, body={"type": "HTTP", "port": [1], "requestPath": "[2]"})

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

💡 Hint

Common Mistakes

Using HTTPS port 443 for HTTP health checks.

Using incorrect request paths.

HTTP health checks typically use port 80 and a path like '/healthz' to verify backend health.

5fill in blank

hard

Fill all three blanks to define a URL map with path matcher and host rule for the HTTP(S) Load Balancer.

GCP

url_map = compute.urlMaps().insert(project=project_id, body={"hostRules": [{"hosts": ["[1]"], "pathMatcher": "[2]"}], "pathMatchers": [{"name": "[3]", "defaultService": backend_service_url}]})

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

CpathMatcher1

💡 Hint

Common Mistakes

Mismatching path matcher names.

Using invalid host names.

The host rule uses the domain 'example.com', and the path matcher name must match between hostRules and pathMatchers, here 'path-matcher-1'.
