Exam Associate Cloud Engineer topic 1 question 173 discussion

C, Cloud Spanner, keywords are globally, relational structure and lastly "clients from all over the world should get the exact identical state of the data" which implies strong consistency is needed.

The best option is: C. Use Cloud Spanner for data storage. Reason: Cloud Spanner is the only Google Cloud database that provides: Global consistency: Ensures all users worldwide see the exact same state of the data. Relational structure: Fully supports SQL queries and relational database schema. Low latency: Replicates data across multiple regions to minimize read/write latency for global users. Scalability: Designed to handle high-scale applications like financial trading. Other options don't meet the requirements: A. Cloud Bigtable: No relational structure; optimized for wide-column use cases, not relational data. B. Cloud SQL: Limited to regional deployments, not suitable for globally distributed applications. D. Firestore: Designed for document-based structures, not ideal for relational database use.

question demands, exact state of data and minimum latency to users , for this cloud spanner is the only option

financial trading application relational structure multiple regions

C, always you need to select BBDD check for data analysis bigquery, something very big or fast bigtable, something with HA cloud sql, and something globally available cloud spanner, the key here is globaly available

it's C 100% Guys come on, it's a pretty straight forward scenario. if you have the keywords "relational DB" and the word "Globally" in a sentence always go for Cloud Spanner.

C. is the answer

Why not A. Big table as per keywords relational, global and low latency

C is the answer. Cloud Spanner is a global relational database.

Should be the correct answer.

C, Cloud Spanner. Globally and trading (tend to receive 1000s Records per second) are key here.

Why not CLoud Sql with replicas in multiple region to serve "global" ?
