NEW QUESTION # 82
You want to migrate an existing on-premises application to Google Cloud. Your application supports semi-structured data ingested from 100,000 sensors, and each sensor sends 10 readings per second from manufacturing plants. You need to make this data available for real-time monitoring and analysis. What should you do?
- A. Deploy the database using Cloud SQL.
- B. Use BigQuery, and load data in batches.
- C. Deploy the database using Cloud Spanner.
- D. C.Deploy the database using Bigtable.
Answer: D
Explanation:
Bigtable is a scalable, fully managed, and high-performance NoSQL database service that can handle semi-structured data and support real-time monitoring and analysis. Cloud SQL is a relational database service that does not support semi-structured dat a. BigQuery is a data warehouse service that is optimized for batch processing and analytics, not real-time monitoring. Cloud Spanner is a relational database service that supports semi-structured data with JSON data type, but it is more expensive and complex than Bigtable for this use case.
NEW QUESTION # 83
Your retail organization is preparing for the holiday season. Use of catalog services is increasing, and your DevOps team is supporting the Cloud SQL databases that power a microservices-based application. The DevOps team has added instrumentation through Sqlcommenter. You need to identify the root cause of why certain microservice calls are failing. What should you do?
- A. Watch the Cloud SQL instance monitor for CPU utilization metrics.
- B. Watch the Cloud SQL recommenders for overprovisioned instances.
- C. Watch Query Insights for long running queries.
- D. Watch Cloud Trace for application requests that are failing.
Answer: C
Explanation:
Cloud Trace doesn't support Cloud SQL. Eliminate D. Cloud SQL recommenders for overprovisioned instances would tell you about Cloud SQL instances which are too largefor their workload. Eliminate C.
Monitoring CPU utilization wouldn't tell you why microservice calls are failing. Eliminate B. SQLcommenter integrates with Query Insights. So A is the best answer. https://cloud.google.com/blog/topics/developers- practitioners/introducing-sqlcommenter-open-source-orm-auto-instrumentation-library
