Google Professional Cloud Architect Exam - Topic 4 Question 53 Discussion

Actual exam question for Google's Professional Cloud Architect exam

Question #: 53
Topic #: 4

[All Professional Cloud Architect Questions]

You are developing an application using different microservices that should remain internal to the cluster. You want to be able to configure each microservice with a specific number of replicas. You also want to be able to address a specific microservice from any other microservice in a uniform way, regardless of the number of replicas the microservice scales to. You need to implement this solution on Google Kubernetes Engine. What should you do?

ADeploy each microservice as a Deployment. Expose the Deployment in the cluster using a Service, and use the Service DNS name to address it from other microservices within the cluster.

BDeploy each microservice as a Deployment. Expose the Deployment in the cluster using an Ingress, and use the Ingress IP address to address the Deployment from other microservices within the cluster.

CDeploy each microservice as a Pod. Expose the Pod in the cluster using a Service, and use the Service DNS name to address the microservice from other microservices within the cluster.

DDeploy each microservice as a Pod. Expose the Pod in the cluster using an Ingress, and use the Ingress IP address name to address the Pod from other microservices within the cluster.

I thought Ingress was only for external traffic. Is that right?

Deploying as Pods? No thanks, stick with Deployments!

Wait, why would you use Ingress for internal communication? Seems off.

I agree, using Service DNS is the best practice here.

A is definitely the way to go! Services are perfect for this.

I vaguely recall that Ingress is more for external traffic, so maybe we should stick with Services for internal communication?

I feel like using Pods directly might not be the best choice since they don't handle scaling as well as Deployments do.

I remember practicing a similar question where we used Service DNS names to address microservices. That seems like the right approach here too.

I think we should definitely use Deployments for each microservice, but I'm not sure if it's better to use a Service or Ingress for internal communication.

I'm a little confused by this question. I know encryption and digital signatures are security mechanisms, but I'm not sure if the others fit that category. I'll have to review my notes and think this through before answering.

I'm pretty confident that the correct answer is B. Configuring one Node Manager per machine with any number of WebLogic instances makes the most sense.
