For performance and scalability, it's important to optimize the cache hit ratio. By default, Cloud CDN uses the complete request URL to build the cache key. To help optimize your cache hit ratio, you can use custom cache keys so that Cloud CDN doesn't unnecessarily shard the cache. https://cloud.google.com/cdn/docs/best-practices#cache-hit-ratio Answer is A
