Kubernetes - Advanced Deployment Patterns

Given this Kubernetes deployment snippet for progressive delivery:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp-v2
  labels:
    version: v2
spec:
  replicas: 2
  selector:
    matchLabels:
      version: v2
  template:
    metadata:
      labels:
        version: v2
    spec:
      containers:
      - name: myapp
        image: myapp:2.0

What does this configuration do?

ADeploys two pods running version 2.0 of myapp labeled as v2

BDeletes all pods labeled v2 and replaces with version 1.0

CCreates a service exposing version 1.0 of myapp

DScales the existing deployment to zero replicas

Step-by-Step Solution

Solution:

Step 1: Analyze deployment metadata and labels
The deployment is named myapp-v2 and uses label version: v2 for pods.
Step 2: Check replicas and container image
It creates 2 replicas running image myapp:2.0, matching label v2.
Final Answer:
Deploys two pods running version 2.0 of myapp labeled as v2 -> Option A
Quick Check:
Deployment with replicas=2 and image v2 = Deploys two pods running version 2.0 of myapp labeled as v2 [OK]

Quick Trick: Look for replicas and image tags to identify deployment version [OK]

Common Mistakes:

Confusing deployment labels with service exposure
Assuming deletion instead of creation
Mixing version labels with scaling actions
