Kubernetes - Resource Management

A pod has two containers with these resource specs:

Container A: requests=cpu 200m, memory 256Mi; limits=cpu 200m, memory 256Mi
Container B: requests=cpu 100m, memory 128Mi; limits=cpu 200m, memory 256Mi

What QoS class will Kubernetes assign to this pod?

AGuaranteed

BBurstable

CBestEffort

DNone

Step-by-Step Solution

Solution:

Step 1: Review container resource specs
Container A has equal requests and limits, Container B has requests less than limits.
Step 2: Understand pod QoS classification
Pod is Guaranteed only if all containers have equal requests and limits for all resources.
Step 3: Determine QoS class
Since Container B's requests are less than limits, pod is classified as Burstable.
Final Answer:
Burstable -> Option B
Quick Check:
Any container with requests < limits makes pod Burstable [OK]

Quick Trick: All containers must have equal requests and limits for Guaranteed [OK]

Common Mistakes:

Assuming one container's Guaranteed spec makes pod Guaranteed
Confusing Burstable with BestEffort
Ignoring per-container resource differences
