Your project has all its Compute Engine resources in the europe-west1 region. You want to set europe-west1 as the default region for gcloud commands. What should you do?

• A.Use Cloud Shell instead of the command line interface of your device. Launch Cloud Shell after you navigate to a resource in the europe-west1 region. The europe-west1 region will automatically become the default region.
• B.Use "gcloud config set compute/region europe-west1" to set the default region for future gcloud commands.
• C.Use "gcloud config set compute/zone europe-west1" to set the default region for future gcloud commands.
• D.Create a VPN from on-premises to a subnet in europe-west1, and use that connection when executing gcloud commands.

You are building a product on top of Google Kubernetes Engine (GKE). You have a single GKE cluster. For each of your customers, a Pod is running in that cluster, and your customers can run arbitrary code inside their Pod. You want to maximize the isolation between your customers' Pods. What should you do?

• A.Use Binary Authorization and whitelist only the container images used by your customers' Pods.
• B.Use the Container Analysis API to detect vulnerabilities in the containers used by your customers' Pods.
• C.Create a GKE node pool with a sandbox type configured to gvisor. Add the parameter runtimeClassName: gvisor to the specification of your customers' Pods.
• D.Use the cos_containerd image for your GKE nodes. Add a nodeSelector with the value cloud.google.com/gke-os-distribution: cos_containerd to the specification of your customers' Pods.

Users of your application are complaining of slowness when loading the application. You realize the slowness is because the App Engine deployment serving the application is deployed in us-central whereas all users of this application are closest to europe-west3. You want to change the region of the App Engine application to europe-west3 to minimize latency. What's the best way to change the App Engine region?

• A.Create a new project and create an App Engine instance in europe-west3
• B.Use the gcloud app region set command and supply the name of the new region.
• C.From the console, under the App Engine page, click edit, and change the region drop-down.
• D.Contact Google Cloud Support and request the change.
