Kubernetes - Resource Management

You want to ensure a pod gets guaranteed CPU and memory resources but also allow it to burst beyond the requested amount when available. Which resource configuration and QoS class combination achieves this?

ASet no requests or limits; QoS class BestEffort

BSet requests equal to limits; QoS class Guaranteed

CSet requests less than limits; QoS class Burstable

DSet limits less than requests; QoS class Burstable

Step-by-Step Solution

Solution:

Step 1: Understand resource guarantees and bursting
Guaranteed QoS requires requests equal to limits, which means no bursting beyond limits. Burstable allows requests less than limits, enabling bursting.
Step 2: Match configuration to desired behavior
Setting requests less than limits gives minimum guaranteed resources with ability to burst, which is Burstable QoS.
Final Answer:
Set requests less than limits; QoS class Burstable -> Option C
Quick Check:
Burstable = guaranteed minimum + burst capacity [OK]

Quick Trick: Burstable = requests less than limits for bursting [OK]

Common Mistakes:

Choosing Guaranteed which disallows bursting
Setting limits less than requests (invalid)
Assuming BestEffort provides guarantees
