Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
An e-commerce platform uses Cloud Spanner in a multi-region configuration. They want to achieve the highest possible availability SLA. Which deployment configuration should they choose?
Correct answer & explanation
Cloud Spanner offers a 99.999% SLA for multi-region configurations. To achieve this, you must use a multi-region instance (e.g., nam3, eur3) that replicates data across at least three regions. A single-region configuration only offers 99.99% SLA.
