Free Google Professional Cloud Database Engineer Actual Exam Questions - Question 3 Discussion
in one country and eventually expand to millions of users in a global audience. You need to ensure
that the application can run 24/7 with minimal downtime for maintenance. What should you do?
I think B is the better pick here. Multi-region Cloud Spanner is designed for global scale and continuous availability, which fits the 24/7 minimal downtime requirement way better than regional setups or Cloud SQL options. Starting with A might save cost initially, but you'd have to switch later, adding complexity. C and D just don’t handle the global scale and uptime as smoothly. So, B makes the most sense from the start to avoid downtime and support millions of users worldwide.
C/D? Cloud SQL can scale but might struggle with global 24/7 uptime.
Maybe B is the best since multi-region Cloud Spanner handles global scale and uptime well. A regional setup like A might struggle when expanding beyond one country.
B sounds best since multi-region config supports global scale and high availability with minimal downtime. A is regional, which might limit scale later.
