Google Professional Cloud Network Engineer Exam - Topic 6 Question 60 Discussion

You have several microservices running in a private subnet in an existing Virtual Private Cloud (VPC). You need to create additional serverless services that use Cloud Run and Cloud Functions to access the microservices. The network traffic volume between your serverless services and private microservices is low. However, each serverless service must be able to communicate with any of your microservices. You want to implement a solution that minimizes cost. What should you do?
D) Create a serverless VPC access connector. Configure the serverless service to use the connector for communication to the microservices.
A) Deploy your serverless services to the serverless VPC. Peer the serverless service VPC to the existing VPC. Configure firewall rules to allow traffic between the serverless services and your existing microservices.
B) Create a serverless VPC access connector for each serverless service. Configure the connectors to allow traffic between the serverless services and your existing microservices.
C) Deploy your serverless services to the existing VPC. Configure firewall rules to allow traffic between the serverless services and your existing microservices.

Wait, can you really use a single VPC access connector for multiple services?

I recall that peering VPCs can be costly and complex. I wonder if option A is really necessary when we have simpler options like B or D.

I practiced a similar question where we had to set up communication between services. I think option D sounds familiar, but I’m not confident if it’s the most cost-effective solution.

I’m not entirely sure, but I feel like deploying serverless services directly to the existing VPC could complicate things. Maybe option C is not the best?

I remember something about VPC access connectors being essential for serverless services to communicate with private resources. I think option B might be the right choice.

This question seems pretty straightforward. I'll start by reading through the options carefully and trying to identify the three key functionalities of VAAI.

Hmm, I'm a bit unsure about this one. I'll need to double-check my HTML knowledge to make sure I choose the right option.

Hmm, this looks like a tricky one. I'll need to carefully consider the options and think through the possible causes of the "not secure" warning.

This is a good one to focus on. The key is to think about what factors the organization considers most important when assessing risk and impact.
