   You have deployed an HTTP(s) Load Balancer with the gcloud commands shown below.

   

   Health checks to port 80 on the Compute Engine virtual machine instance are failing and no traffic is sent to your instances. You want to resolve the problem. Which commands should you run?

   • Agcloud compute instances add-access-config ${NAME}-backend-instance-1
   • Bgcloud compute instances add-tags ${NAME}-backend-instance-1 --tags http-server
   • Cgcloud compute firewall-rules create allow-lb --network load-balancer --allow tcp --source-ranges 130.211.0.0/22,35.191.0.0/16 --direction INGRESS
   • Dgcloud compute firewall-rules create allow-lb --network load-balancer --allow tcp --destination-ranges 130.211.0.0/22,35.191.0.0/16 --direction EGRESS

   Show answer

   Answer: C

   Explanation

   C the source IP ranges for health checks (including legacy health checks if used for HTTP(S) Load Balancing) are: 35.191.0.0/16 130.211.0.0/22 Furthermore it should be direction INGRESS since the health-check (ping) is coming into the load balancer/instance. source: https://cloud.google.com/load-balancing/docs/health-checks

2. Question 272 · 357 in bank

   You are planning to deploy your application in a Google Kubernetes Engine (GKE) cluster. Your application can scale horizontally, and each instance of your application needs to have a stable network identity and its own persistent disk. Which GKE object should you use?

   • ADeployment
   • BStatefulSet
   • CReplicaSet
   • DReplicaController

   Show answer

   Answer: B

   Explanation

   Once created, the StatefulSet ensures that the desired number of Pods are running and available at all times. The StatefulSet automatically replaces Pods that fail or are evicted from their nodes, and automatically associates new Pods with the storage resources, resource requests and limits, and other configurations defined in the StatefulSet's Pod specification

3. Question 273 · 357 in bank

   You are using Cloud Build to build a Docker image. You need to modify the build to execute unit and run integration tests. When there is a failure, you want the build history to clearly display the stage at which the build failed. What should you do?

   • AAdd RUN commands in the Dockerfile to execute unit and integration tests.
   • BCreate a Cloud Build build config file with a single build step to compile unit and integration tests.
   • CCreate a Cloud Build build config file that will spawn a separate cloud build pipeline for unit and integration tests.
   • DCreate a Cloud Build build config file with separate cloud builder steps to compile and execute unit and integration tests.

   Show answer

   Answer: D

   Explanation

   https://cloud.google.com/build/docs/build-config-file-schema: "A build step specifies an action that you want Cloud Build to perform. For each build step, Cloud Build executes a docker container as an instance of docker run. Build steps are analogous to commands in a script and provide you with the flexibility of executing arbitrary instructions in your build." D makes the most sense here

   • DUse Google Kubernetes Engine for automated deployments.
   • EUse a large Google Compute Engine cluster for deployments.

   Show answer

   Answer: CD

   Explanation

   App Engine cannot be a solution here as it limits the application to be in a single region. We need to note that the case study has explicitly mentioned that the application needs to be global, which means multi-regional. So, I will go with C & D.

    • CMove the state storage to Cloud Spanner.
    • DReplace the MySQL instance with Cloud SQL.

    Show answer

    Answer: C

    Explanation

    For me the answer is C. A is not valid because local SSD is volatile memory. B and D is bad solution because it don't reduce latency in world wide but they are a regional location.
