Answer: Configure cluster notifications to be sent to a Pub/Sub topic.
The correct answer is A because configuring cluster notifications to a Pub/Sub topic is the recommended method to receive real-time alerts about GKE cluster events such as upgrades and security bulletins. GKE natively supports sending notifications to Pub/Sub, which can then be routed to other services (e.g., email, Slack) via subscribers. Options B, C, and D are less direct or require manual intervention: querying BigQuery (B) or the GKE API (C) involves polling rather than event-driven alerts, and an RSS feed (D) may not provide timely or cluster-specific details.
