You have a data pipeline that writes data to Cloud Bigtable using well-designed row keys. You want to monitor your pipeline to determine when to increase the size of you Cloud Bigtable cluster…

Question

Options

• AReview Key Visualizer metrics. Increase the size of the Cloud Bigtable cluster when the Read pressure index is above 100.
• BReview Key Visualizer metrics. Increase the size of the Cloud Bigtable cluster when the Write pressure index is above 100.
• CMonitor the latency of write operations. Increase the size of the Cloud Bigtable cluster when there is a sustained increase in write latency.
• DMonitor storage utilization. Increase the size of the Cloud Bigtable cluster when utilization increases above 70% of max capacity.
• EMonitor latency of read operations. Increase the size of the Cloud Bigtable cluster of read operations take longer than 100 ms.

• A
  11% (4)
• B
  5% (2)
• C
  81% (30)
• E
