Kubernetes - Labels and Selectors

If you run kubectl get pods -l app=web,env=dev, which pods will be listed given:
pod1: app=web, env=prod
pod2: app=web, env=dev
pod3: app=db, env=dev

Apod1 and pod2

Bpod2 only

Cpod2 and pod3

Dpod1, pod2, and pod3

Step-by-Step Solution

Solution:

Step 1: Analyze label selector
The selector requires both 'app=web' and 'env=dev'.
Step 2: Check pods against selector
pod2 matches both labels; pod1 and pod3 do not.
Final Answer:
pod2 only -> Option B
Quick Check:
Multiple label selectors require all labels matched = A [OK]

Quick Trick: Multiple labels in selector mean AND condition [OK]

Common Mistakes:

Assuming OR condition between labels
Selecting pods missing one label
Ignoring label key-value pairs
