medium📝 Command Output Q5 of 15
Kubernetes - Services
What will happen if you try to create a NodePort service with nodePort set to 29999?
AService will be created successfully
BService creation will fail due to invalid nodePort range
CService will default to a random nodePort in valid range
DService will be created but nodePort will be ignored
Step-by-Step Solution
Solution:

  1. Step 1: Recall valid nodePort range

    NodePort must be within 30000-32767 by default; 29999 is outside this range.

  2. Step 2: Understand Kubernetes validation

    Kubernetes rejects services with nodePort outside the valid range, causing creation failure.

  3. Final Answer:

    Service creation will fail due to invalid nodePort range -> Option B

  4. Quick Check:

    nodePort outside 30000-32767 causes creation failure [OK]
Quick Trick: NodePort must be within 30000-32767 or creation fails [OK]
Common Mistakes:
  • Assuming Kubernetes auto-corrects invalid nodePort
  • Thinking nodePort outside range is allowed
  • Confusing nodePort with port or targetPort
