EX280 Storage And Persistent Volumes Practice Question
Which THREE factors influence whether a pod requesting a storage volume can be successfully scheduled to a specific worker node when using topology-aware storage?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Volume accessibility constraints reported by the CSI driver
Topology-aware scheduling considers node topology labels, volume accessibility constraints, and availability zones matching the provisioned PV.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The cluster OAuth token expiration time
Why it's wrong here
Token expiration does not impact storage node scheduling.
- ✓
Volume accessibility constraints reported by the CSI driver
Why this is correct
CSI drivers report which nodes can access specific volume topologies.
- ✗
The number of container image layers in the pod spec
Why it's wrong here
Image layers do not affect storage topology scheduling.
- ✓
The volumeBindingMode set to WaitForFirstConsumer on the StorageClass
Why this is correct
WaitForFirstConsumer allows the scheduler to weigh node topology before provisioning.
- ✓
Node topology labels (such as failure-domain.beta.kubernetes.io/zone)
Why this is correct
Topology labels define zone and region constraints.
