Topic 1 Question 33
Your software uses a simple JSON format for all messages. These messages are published to Google Cloud Pub/Sub, then processed with Google Cloud Dataflow to create a real-time dashboard for the CFO. During testing, you notice that some messages are missing in the dashboard. You check the logs, and all messages are being published to Cloud Pub/Sub successfully. What should you do next?
Check the dashboard application to see if it is not displaying correctly.
Run a fixed dataset through the Cloud Dataflow pipeline and analyze the output.
Use Google Stackdriver Monitoring on Cloud Pub/Sub to find the missing messages.
Switch Cloud Dataflow to pull messages from Cloud Pub/Sub instead of Cloud Pub/Sub pushing messages to Cloud Dataflow.

The most efficient solution would be to run a fixed dataset through the Cloud Dataflow pipeline and analyze the output (Option B). This will allow you to determine if the issue is with the pipeline or with the dashboard application. By analyzing the output, you can see if the messages are being processed correctly and determine if there are any discrepancies or missing messages. If the issue is with the pipeline, you can then debug and make any necessary updates to ensure that all messages are processed correctly. If the issue is with the dashboard application, you can then focus on resolving that issue. This approach allows you to isolate and identify the root cause of the missing messages in a controlled and efficient manner.
