Ultimate access to all questions.
You need to grant external auditors access to sensitive files for a limited time period of 4 hours only, ensuring the files are inaccessible thereafter. According to Google best practices, what is the most efficient method to share these files?
Explanation:
The correct answer is A because using Cloud Storage signed URLs is the most efficient and secure way to share files for a limited time. Signed URLs provide time-limited access to anyone in possession of the URL, without requiring a Google account. This method is quick and adheres to Google's best practices for secure file sharing. Options B and D involve unnecessary manual effort and are not quick solutions. Option C is incorrect as granting allUsers
access is not secure and would make the file public.
