C imo. Spanner is the only option here that gives you both strong consistency and global distribution with HA and no downtime. A and B can't guarantee all these, D is more for analytics. Anyone disagree?
C imo. is the one you want. Spanner covers global scale with strong consistency and zero downtime, which matches the scenario best. Official exam guide and labs show Spanner as the go-to for strict HA like this. Correct me if I'm missing something.
Probably C for this. Spanner is engineered for global scale plus strong consistency and real HA, fits all requirements. A and B can’t do true zero downtime globally, D’s more eventual consistency focused (good for analytics but not strict transactional apps). I’ve seen similar logic on practice questions, pretty sure C’s the intended answer here.
Its C, Spanner is designed for global distribution, strong consistency, and HA. No downtime. Let me know if you disagree.
