Kubernetes - Labels and Selectors

Given pods with labels:
pod1: app=frontend, env=prod
pod2: app=frontend, env=dev
What is the output of kubectl get pods -l app=frontend,env=prod?

ALists pod1 and pod2

BLists only pod1

CLists only pod2

DNo pods listed

Step-by-Step Solution

Solution:

Step 1: Analyze label selector
The command filters pods with both labels app=frontend and env=prod.
Step 2: Match pods to labels
Only pod1 has both labels; pod2 has env=dev, so it is excluded.
Final Answer:
Lists only pod1 -> Option B
Quick Check:
Label AND filter = pods matching all labels [OK]

Quick Trick: Label selectors with commas mean AND condition [OK]

Common Mistakes:

Assuming comma means OR
Listing pods missing one label
Confusing env=prod with env=dev
