How to create a headless service?

Answer options

• A. By specifying .spec.ClusterIP: headless
• B. By specifying .spec.clusterIP: None
• C. By specifying .spec.ClusterIP: 0.0.0.0
• D. By specifying .spec.ClusterIP: localhost

Correct answer: B

Explanation

The correct method to create a headless service is by setting .spec.clusterIP to None, which indicates that no cluster IP should be assigned. The other options either do not conform to the required specification or do not correctly indicate the absence of a cluster IP.
