Question No. 1

You need to redesign the architecture of an application that currently uses Cloud SQL for PostgreSQL. The users of the application complain about slow query response times. You want to enhance your application architecture to offer sub-millisecond query latency. What should you do?

AConfigure Firestore, and modify your application to offload queries.

BConfigure Bigtable, and modify your application to offload queries.

CConfigure Cloud SQL for PostgreSQL read replicas to offload queries.

DConfigure Memorystore, and modify your application to offload queries.

Show Answer

Correct Answer: D

'sub-millisecond latency' always involves Memorystore. Furthermore, as we are talking about a relational DB (Cloud SQL), BigTable is not a solution to be considered.

Question No. 2

Your organization stores marketing data such as customer preferences and purchase history on Bigtable. The consumers of this database are predominantly data analysts and operations users. You receive a service ticket from the database operations department citing poor database performance between 9 AM-10 AM every day. The application team has confirmed no latency from their logs. A new cohort of pilot users that is testing a dataset loaded from a third-party data provider is experiencing poor database performance. Other users are not affected. You need to troubleshoot the issue. What should you do?

AIsolate the data analysts and operations user groups to use different Bigtable instances.

BCheck the Cloud Monitoring table/bytes_used metric from Bigtable.

CUse Key Visualizer for Bigtable.

DAdd more nodes to the Bigtable cluster.

The database in region R1 fails over successfully to region R2, and the database becomes available for the application to process dat

a. During testing, certain scenarios of the application work as expected in region R2, but a few scenarios fail with database errors. The application-related database queries, when executed in isolation from Cloud SQL for PostgreSQL in region R2, work as expected. The application performs completely as expected when the database fails back to region R1. You need to identify the cause of the database errors in region R2. What should you do?

ADetermine whether the versions of Cloud SQL for PostgreSQL in regions R1 and R2 are different.

BDetermine whether the database patches of Cloud SQI for PostgreSQL in regions R1 and R2 are different.

CDetermine whether the failover of Cloud SQL for PostgreSQL from region R1 to region R2 is in progress or has completed successfully.

DDetermine whether Cloud SQL for PostgreSQL in region R2 is a near-real-time copy of region R1 but not an exact copy.

Show Answer

Correct Answer: D

Verify that the replica has processed all the transactions it has received from the primary. This ensures that when promoted, the replica reflects all transactions that were received before the primary became unavailable. https://cloud.google.com/sql/docs/postgres/replication/cross-region-replicas#verify_failover_criteria
