Question 10
You have a latency-sensitive application that uses Bigtable. You want to follow Google Cloud recommended best practices. What would you do?
-
A
Use a service account for all read operations
- B Keep storage utilization per node below 60%
- C Use HDD storage instead of SSD storage
- D Use a global load balancer in front of Bigtable
Reveal correct answer
Correct answer: B
Explanation
For low latency applications, Google Cloud recommends keeping storage utilization below 60%. Using service accounts for read operations will not affect latency of write operations. HDD storage is less performant than SSD storage. A load balancer is not needed to distribute workload within a Bigtable cluster. Bigtable distributes operations based on row keys.
