You want to configure autohealing for network load balancing for a group of Compute Engine instances that run in multiple zones, using the fewest possible steps. You need to configure re- creation of VMs if they are unresponsive after 3 attempts of 10 seconds each. What should you do?

• A.Create an HTTP load balancer with a backend configuration that references an existing instance group.
  Set the health check to healthy (HTTP)
• B.Create an HTTP load balancer with a backend configuration that references an existing instance group.
  Define a balancing mode and set the maximum RPS to 10.
• C.Create a managed instance group. Set the Autohealing health check to healthy (HTTP)
• D.Create a managed instance group. Verify that the autoscaling setting is on.

You have developed a containerized web application that will serve internal colleagues during business hours. You want to ensure that no costs are incurred outside of the hours the application is used. You have just created a new Google Cloud project and want to deploy the application. What should you do?

• A.Deploy the container on Cloud Run for Anthos, and set the minimum number of instances to zero.
• B.Deploy the container on Cloud Run (fully managed), and set the minimum number of instances to zero.
• C.Deploy the container on App Engine flexible environment with autoscaling, and set the value min_instancesto zero in the app.yaml.
• D.Deploy the container on App Engine flexible environment with manual scaling, and set the value instancesto zero in the app.yaml.

You create a Deployment with 2 replicas in a Google Kubernetes Engine cluster that has a single preemptible node pool. After a few minutes, you use kubectl to examine the status of your Pod and observe that one of them is still in Pending status:

What is the most likely cause?

• A.The pending Pod's resource requests are too large to fit on a single node of the cluster.
• B.Too many Pods are already running in the cluster, and there are not enough resources left to schedule the pending Pod.
• C.The node pool is configured with a service account that does not have permission to pull the container image used by the pending Pod.
• D.The pending Pod was originally scheduled on a node that has been preempted between the creation of the Deployment and your verification of the Pods' status. It is currently being rescheduled on a new node.

You built an application on your development laptop that uses Google Cloud services. Your application uses Application Default Credentials for authentication and works fine on your development laptop. You want to migrate this application to a Compute Engine virtual machine (VM) and set up authentication using Google- recommended practices and minimal changes. What should you do?

• A.Assign appropriate access for Google services to the service account used by the Compute Engine VM.
• B.Create a service account with appropriate access for Google services, and configure the application to use this account.
• C.Store credentials for service accounts with appropriate access for Google services in a config file, and deploy this config file with your application.
• D.Store credentials for your user account with appropriate access for Google services in a config file, and deploy this config file with your application.

You are using Google Kubernetes Engine with autoscaling enabled to host a new application. You want to expose this new application to the public, using HTTPS on a public IP address. What should you do?

• A.Create a Kubernetes Service of type NodePort to expose the application on port 443 of each node of the Kubernetes cluster. Configure the public DNS name of your application with the IP of every node of the cluster to achieve load-balancing.
• B.Create a Kubernetes Service of type ClusterIP for your application. Configure the public DNS name of your application using the IP of this Service.
• C.Create a HAProxy pod in the cluster to load-balance the traffic to all the pods of the application.
  Forward the public traffic to HAProxy with an iptable rule. Configure the DNS name of your application using the public IP of the node HAProxy is running on.
• D.Create a Kubernetes Service of type NodePort for your application, and a Kubernetes Ingress to expose this Service via a Cloud Load Balancer.
