- A
NodePort
Exposes service on each Node's IP at a static port.
- B
Deployment
Why wrong: Deployment is a workload resource, not a Service type.
- C
ClusterIP
Default type, exposes service on a cluster-internal IP.
- D
LoadBalancer
Exposes service externally using a cloud provider's load balancer.
- E
Ingress
Why wrong: Ingress is an API object that manages external access, not a Service type.

200-901 Application Deployment and Security Practice Question
This 200-901 practice question tests your understanding of application deployment and security. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 are valid Kubernetes Service types? (Select three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
NodePort
A is correct because NodePort is a standard Kubernetes Service type that exposes a service on a static port (30000-32767) on each node's IP address, allowing external traffic to reach the service by targeting <NodeIP>:<NodePort>. It builds on top of ClusterIP and is commonly used for development or direct access scenarios.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between Kubernetes resource types (e.g., Deployment, Ingress) and actual Service types, so candidates mistakenly select Ingress or Deployment because they associate them with external access, but only NodePort, ClusterIP, and LoadBalancer are valid Service types.
Detailed technical explanation
How to think about this question
Kubernetes Service types define how traffic is routed to pods: ClusterIP (default) exposes the service on a cluster-internal IP, NodePort extends ClusterIP by opening a port on every node, and LoadBalancer provisions an external load balancer (e.g., from a cloud provider) that forwards traffic to the NodePort. Under the hood, kube-proxy implements these via iptables, IPVS, or userspace mode, managing DNAT rules to direct packets to healthy pods. In real-world scenarios, NodePort is often used for on-premises setups where no cloud LB is available, but it requires manual node firewall configuration.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-901 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.
