[All 1Z0-1109-23 Questions]

You host a microservices based application on the Oracle Cloud Infrastructure Con-tainer Engine for Kubernetes (OKE). Due to increased popularity of your application, you need to provision more resources to meet the growing demand. Which three statements are true for the given scenario?

Show Suggested Answer Hide Answer
Suggested Answer: A, B, E

The statements that are true for scaling an OKE cluster to meet growing demand are:

Enable autoscaling by autoscaling Pods by deploying Kubernetes Autoscaler to collect resource metrics from each worker node in the cluster. Pod autoscaling is a feature that allows you to adjust the number of pods in a deployment or replica set based on the CPU or memory utilization of the pods. You can use Kubernetes Autoscaler, which is an add-on component that you can install on your OKE cluster, to collect resource metrics from each worker node and scale the pods up or down accordingly.

Enable cluster autoscaling by autoscaling node pools by deploying the Kubernetes Autoscaler to automatically resize a cluster's node pools based on application workload demands. Cluster autoscaling is a feature that allows you to adjust the number of nodes in a node pool based on the pod requests and limits of the pods running on the nodes. You can use Kubernetes Autoscaler, which is an add-on component that you can install on your OKE cluster, to monitor the pod requests and limits and scale the node pools up or down accordingly.

Scale a node pool up and down to change the number of worker nodes in the node pool, and the availability domains and subnets in which to place them. A node pool is a group of worker nodes within an OKE cluster that share the same configuration, such as shape, image, subnet, etc. You can use OCI Console, CLI, or API to scale a node pool up and down by adding or removing worker nodes from it. You can also change the availability domains and subnets for your node pool to distribute your nodes across different fault domains. Scaling a node pool allows you to adjust your cluster capacity according to your application workload demands.

Haha, I love how they try to confuse us with all these options. But B and E are the obvious choices here. Simple and effective!

Hmm, I'm not sure about D. Vertical Pod Autoscaler? That sounds a bit complicated for this scenario. I'd stick with B and E.

What a weird question, I mean, who doesn't know that C is the answer? Clearly, the correct answer is to just add more node pools, duh!

I believe option D is also true because using Kubernetes Metrics Server can help adjust resource requests.
