You support an application deployed on Compute Engine.
The application connects to a Cloud SQL instance to store and retrieve data.
After an update to the application, users report errors showing database timeout messages.
The number of concurrent active users remained stable.
You need to find the most probable cause of the database timeout.
What should you do?

A. B. C. D.C.
Option C is the most probable cause of the database timeout.
Database timeouts can occur due to a variety of reasons, such as increased traffic, insufficient resources, or network issues. However, since the number of concurrent active users remained stable, the issue is likely not related to increased traffic.
Option A is not relevant in this case as serial port logs are not related to the database connection or timeout issues.
Option B can be useful in identifying any resource constraints or bottlenecks in the application, but it may not directly identify the cause of the database timeout.
Option D is also not relevant in this case as a DDoS attack is unlikely to cause database timeouts, especially if the number of concurrent users remained stable.
Therefore, Option C is the most appropriate course of action. The first step would be to check whether there has been an increase in the number of connections to the Cloud SQL instance, as this can cause database timeouts if the instance is not able to handle the additional load. This can be done by checking the Cloud SQL instance logs or monitoring the instance's resource utilization. If the number of connections has increased, it may be necessary to scale up the Cloud SQL instance or optimize the application's database queries to improve performance.
