Given the following scenario: You deploy a Kubernetes cluster with 3 nodes and create a Deployment with 5 replicas. What will happen if one node fails?

medium📝 Predict Output Q4 of 15

Docker - Swarm

AThe cluster will shut down due to node failure

BKubernetes will reschedule the lost pods to other nodes to maintain 5 replicas

CThe Deployment will reduce replicas to 2 automatically

DPods on the failed node will remain in pending state indefinitely

Step-by-Step Solution

Solution:

Step 1: Understand Kubernetes self-healing
Kubernetes automatically reschedules pods from failed nodes to healthy nodes to maintain desired replicas.
Step 2: Analyze other options
Deployment does not reduce replicas automatically; cluster does not shut down; pods do not stay pending indefinitely.
Final Answer:
Kubernetes will reschedule the lost pods to other nodes to maintain 5 replicas -> Option B
Quick Check:
Self-healing = C [OK]

Quick Trick: Kubernetes auto-reschedules pods on node failure [OK]

Common Mistakes:

Thinking replicas reduce automatically
Assuming cluster stops on node failure
Believing pods stay pending forever
