Utilization of resources in a Pod

Which QoS class?

Report a typo

Consider the following Pod definition file:

spec:
  containers:
  - name: container1
    image: app1:latest
    resources:
      limits:
        memory: "64Mi"
        cpu: "250m"

What Quality of Service class does this pod belong to? Also, select the statements that explain why the pod belongs to the specified class and the consequences.

Select one or more options from the list

Since there is no resource request, Kubernetes will not reserve any specific amount of resources for the container. So other pods may compete for node resources.

Since request is not specified, the container in the pod can consume as much CPU and memory as it needs, up to the specified resource limit.

Pod will be categorized into Burstable QoS class

Pod will be categorized into Guaranteed QoS class.

When only resource limit is specified, Kubernetes by default will set the value of resource request equal to the value of resource limit.
