This CKAD practice question tests your understanding of application deployment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE of the following are valid ways to expose a set of pods as a network service?
LoadBalancer Service
Exposes externally via cloud load balancer.
Ingress
Why wrong: Ingress is an API object that manages external access, not a Service type.
ClusterIP Service
Default type, exposes internally.
NodePort Service
Exposes on each node's IP at a static port.
ExternalName Service
Why wrong: Maps to an external DNS name, not pod exposure.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
LoadBalancer Service
A LoadBalancer Service is a valid way to expose a set of pods as a network service because it provisions an external load balancer (e.g., from a cloud provider) that distributes traffic to the pods via a NodePort and ClusterIP underneath. This allows external clients to access the service using a single IP address or hostname, making it suitable for production-grade external exposure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

ExternalName Service
Why it's wrong here

Common exam traps
The trap here is that candidates often confuse Ingress as a Service type or think ExternalName can expose pods, when in fact Ingress is a separate resource and ExternalName only maps to an external DNS name without any pod connectivity.
Detailed technical explanation
Under the hood, a LoadBalancer Service creates a NodePort and ClusterIP automatically, and the cloud controller manager provisions an external load balancer (e.g., AWS ELB, GCP TCP/UDP Load Balancer) that forwards traffic to the NodePort on each node. A subtle behavior is that if the cloud provider does not support LoadBalancer, the Service remains in 'pending' state, and the external IP is never assigned—this is a common issue in on-premises or minikube environments.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the CKAD exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
