💡 Hint

Common Mistakes

Using 'false' instead of 'true' disables CDN.

Using 'enable' or 'on' are invalid values.

To enable Cloud CDN on a backend service, the flag --enable-cdn must be set to true.

💡 Hint

Common Mistakes

Using instance group name instead of backend service.

Confusing load balancer name with backend service.

The URL map should point to the backend service name where Cloud CDN is enabled.

Fix the error in the command to invalidate cached content on Cloud CDN.

GCP

gcloud compute url-maps invalidate-caches my-url-map --path [1]

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

💡 Hint

Common Mistakes

Omitting the leading slash causes the command to fail.

Not using wildcards invalidates only a single file.

The path must start with a slash to correctly specify the cache invalidation path.

4fill in blank

hard

Fill both blanks to configure cache key policies for Cloud CDN.

GCP

gcloud compute backend-services update my-backend-service --cache-key-include-[1]=[2]

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

Btrue

Cfalse

Dheader

💡 Hint

Common Mistakes

Setting include flag to false disables query string caching.

Using 'header' instead of 'query-string' changes cache key behavior.

To include query strings in the cache key, use query-string=true.

5fill in blank

hard

Fill all three blanks to define a backend bucket with Cloud CDN enabled and a custom TTL.

GCP

gcloud compute backend-buckets create my-backend-bucket --gcs-bucket-name=[1] --enable-cdn=[2] --default-ttl=[3]

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

💡 Hint

Common Mistakes

Using false disables CDN.

Setting TTL to zero disables caching.

The backend bucket uses the GCS bucket name, enables CDN with true, and sets TTL in seconds.
