What is a recommended best practice to avoid frequent cache invalidations?

Set a very short cache TTL for all content.

Invalidate the entire cache daily.

Use versioned URLs for content that changes.

Disable caching for dynamic content.

A company runs a web application on a managed instance group (MIG) behind a global external Application Load Balancer with Cloud CDN enabled. The application serves both static assets (immutable) and dynamic content (changes frequently). They currently use a single backend service with a TTL of 3600 seconds. Users report that dynamic content is stale for up to an hour. The team wants to fix this without impacting the cache hit ratio for static assets. What is the most effective solution?

Set the `Cache-Control` header on dynamic responses to `no-store`.

Create two backend services: one for static assets with a long TTL and one for dynamic content with a short TTL, and route them via the URL map.

Invalidate the cache for the entire site every time dynamic content changes.

Reduce the TTL on the single backend service to 60 seconds.

What does Cloud CDN cache invalidation do?

Prevents users from accessing cached content.

Permanently deletes content from the origin.

Increases the cache TTL for specific URLs.

Removes cached content for specified URLs or URL prefixes.
