Topic 1 Question 36
You have a storage bucket that contains the following objects: [1] [1] [1] [1] Cloud CDN is enabled on the storage bucket, and all four objects have been successfully cached. You want to remove the cached copies of all the objects with the prefix folder-a, using the minimum number of commands. What should you do?
Add an appropriate lifecycle rule on the storage bucket.
Issue a cache invalidation command with pattern /folder-a/*.
Make sure that all the objects with prefix folder-a are not shared publicly.
Disable Cloud CDN on the storage bucket. Wait 90 seconds. Re-enable Cloud CDN on the storage bucket.

Correct Answer is (B):
You might want to remove an object from the cache prior to its normal expiration time. You can force an object or set of objects to be ignored by the cache by requesting a cache invalidation. Path patterns Each invalidation request specifies a path pattern that identifies the object or set of objects that should be invalidated. The path pattern can be either a specific path, such as /cat.jpg, or an entire directory structure, such as /pictures/*. The following rules apply to path patterns:
The path pattern must start with /. It cannot include ? or #. It must not include an * except as the final character following a /. If it ends with /*, the preceding string is a prefix, and all objects whose paths begin with that prefix are invalidated.
