200-901 Application Deployment and Security Practice Question
This 200-901 practice question tests your understanding of application deployment and security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A developer uses Kubernetes and wants to expose a deployment named 'web-app' externally via a cloud load balancer. Which Service type should be used?
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
✓
LoadBalancer
The LoadBalancer Service type provisions an external cloud load balancer (e.g., AWS ELB, GCP TCP/UDP Load Balancer) that routes external traffic to the 'web-app' deployment's pods. This is the only Service type that directly integrates with a cloud provider's load balancing infrastructure to expose the service externally.
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 misconception that NodePort alone provides external cloud load balancing, but NodePort only exposes the service on node IPs without cloud integration, requiring additional infrastructure for true load balancing.
Detailed technical explanation
How to think about this question
When a LoadBalancer Service is created, Kubernetes automatically provisions a cloud load balancer (e.g., AWS ELB) via the cloud controller manager, which listens on a public IP and forwards traffic to the NodePort or ClusterIP of the Service. The cloud load balancer typically uses TCP/UDP as the transport layer (Layer 4) and can be configured with health checks to target the pods' readiness probes. In real-world scenarios, this is essential for production deployments where external traffic must be balanced across multiple pods with automatic failover.
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.
