B https://cloud.google.com/vpc/docs/flow-logs#log-sampling

B. Enable VPC Flow Logs on the production VPC network frontend and backend subnets only with a sample volume scale of 1.0. VPC flow logs are a feature that allows you to capture network traffic data in your VPC network. To ensure that all network traffic is captured for analysis, you should enable VPC flow logs on the production VPC network frontend and backend subnets with a sample volume scale of 1.0. This will capture all network traffic data, including the potentially malicious process, for further analysis. Option A. Enable VPC Flow Logs on the production VPC network frontend and backend subnets only with a sample volume scale of 0.5 is not adequate, as it captures only half of the network traffic, there is a chance that the logs of the malicious process are not captured. Option C and D, Enable VPC Flow Logs on the testing and production VPC network frontend and backend subnets with a volume scale of 0.5/1.0. Apply changes in testing before production, is not necessary, it's important to have the logs in production environment to detect and mitigate the problem.

Option B

B: enabling VPC Flow Logs on the production VPC network frontend and backend subnets only with a sample volume scale of 1.0. This means that all traffic will be logged, ensuring that all network traffic is captured for analysis.

App Engine grants the Error Reporting Writer role by default. The Error Reporting library for Python can be used without needing to explicitly provide credentials. Error Reporting is automatically enabled for App Engine flexible environment applications. No additional setup is required

in real project background, first we should keep the consistency of configuration between test env and prod env. second, we should apply changes in testing before production.

question saying test envs can be eliminated

Correct answer is B

Submitted B

B is better that A because you are filtering 1:20 instead of 1:10 and the malicious process generates very low traffic

Ans: B

The Answer for this is B

i think Answer: D
