Google Associate Cloud Engineer exam dumps: questions 201 to 300 of 374

Correct answer: B

• A. Incorrect.

  A. Node taints and tolerations are used to repel workloads from specific nodes, rather than ensuring they run on nodes with specific configurations.

• B. Correct.

  B. Creating separate node pools with specific machine types and using node selectors in your pod specifications allows you to target workloads to nodes with specific configurations.

• C. Incorrect.

  C. Cloud Functions cannot be used to move workloads between node pools automatically.

• D. Incorrect.

  D. Configuring a regional cluster does not affect how workloads are scheduled across node pools; it is for high availability and disaster recovery.

Correct answers: A, B, C

• A. Correct.

  A. Correct. Using the gcloud command-line tool with the --enable-autoscaling flag is one way to enable autoscaling for a node pool in GKE.

• B. Correct.

  B. Correct. Setting the --min-nodes and --max-nodes flags determines the range within which the autoscaler can adjust the number of nodes.

• C. Correct.

  C. Correct. Autoscaling can also be enabled and configured through the GKE console by editing the node pool settings.

• D. Incorrect.

  D. Incorrect. Autoscaling policies are set at the node pool level, not within individual Kubernetes Deployments.

• E. Incorrect.

  E. Incorrect. Manually resizing the node pool does not configure autoscaling; it requires automatic scaling configurations.

Correct answers: B, C

• A. Incorrect.

  This option upgrades the entire cluster, which might not be necessary if you only want to upgrade a specific node pool.

• B. Correct.

  Draining nodes ensures that workloads are safely evicted and rescheduled, minimizing downtime during the upgrade process.

• C. Correct.

  This command upgrades the specified node pool and is the recommended approach for upgrading node pools without affecting other parts of the cluster.

• D. Incorrect.

  Deleting and recreating a node pool can cause downtime and data loss if not done carefully, and is not the recommended way to upgrade a node pool.

• E. Incorrect.

  While the cluster autoscaler can help manage node resources, it is not directly involved in the node pool upgrade process.

Correct answers: A, C, D

• A. Correct.

  A. Correct. When creating a new node pool, specifying the machine type is crucial as it determines the resource characteristics of the nodes within that pool.

• B. Incorrect.

  B. Incorrect. Existing workloads do not automatically migrate to new node pools. You need to update the workload configurations to target the new node pool.

• C. Correct.

  C. Correct. Using node selectors in your Pod specifications allows you to direct workloads to specific node pools by matching node labels.

• D. Correct.

  D. Correct. Taints and tolerations are used to manage which workloads can be scheduled onto particular nodes, allowing you to control workload placement in the new node pool.

• E. Incorrect.

  E. Incorrect. While enabling auto-repair and auto-upgrade is a best practice, it is not specifically necessary to utilize multiple node pools. These are management features independent of node pool usage.

Correct answers: A, B, D

• A. Correct.

  A Deployment object is used to manage stateless applications and ensures that the specified number of pod replicas are running.

• B. Correct.

  A Horizontal Pod Autoscaler automatically adjusts the number of pods in a Deployment based on observed CPU utilization or other select metrics.

• C. Incorrect.

  A StatefulSet is used for stateful applications requiring stable, unique pod identifiers and persistent storage, not typically used for stateless applications.

• D. Correct.

  A LoadBalancer service type exposes the application to the internet and distributes traffic across the pods, which is often necessary for web applications.

• E. Incorrect.

  Cluster Autoscaler adjusts the number of nodes in the cluster but is not directly involved in scaling the number of application pods based on CPU utilization.
