Topic 1 Question 112
You operate a logistics company, and you want to improve event delivery reliability for vehicle-based sensors. You operate small data centers around the world to capture these events, but leased lines that provide connectivity from your event collection infrastructure to your event processing infrastructure are unreliable, with unpredictable latency. You want to address this issue in the most cost-effective way. What should you do?
Deploy small Kafka clusters in your data centers to buffer events.
Have the data acquisition devices publish data to Cloud Pub/Sub.
Establish a Cloud Interconnect between all remote data centers and Google.
Write a Cloud Dataflow pipeline that aggregates all data in session windows.

Should be B
👍 31[Removed]2020/03/22C. This is a tricky one. The issue here is the unreliable connection between data collection and data processing infrastructure, and to resolve it in a cost-effective manner. However, it also mentions that the company is using leased lines. I think replacing the leased lines with Cloud InterConnect would solve the problem, and hopefully not be an added expense. https://cloud.google.com/interconnect/docs/concepts/overview

B. Have the data acquisition devices publish data to Cloud Pub/Sub. This would provide a reliable messaging service for your event data, allowing you to ingest and process your data in a timely manner, regardless of the reliability of the leased lines. Cloud Pub/Sub also offers automatic retries and fault-tolerance, which would further improve the reliability of your event delivery. Additionally, using Cloud Pub/Sub would allow you to easily scale up or down your event processing infrastructure as needed, which would help to minimize costs.
