This CKAD practice question tests your understanding of services and networking. 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.
An Ingress has two rules: - host: app.example.com, path: /api -> service-a:80 - host: api.example.com, path: / -> service-b:80 A request to `app.example.com/api/v1` reaches which service?
Both services
Why wrong: Only one path matches.
Neither service
Why wrong: The path matches service-a.
service-a
The path /api matches /api/v1.
service-b
Why wrong: Host is app.example.com, not api.example.com.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
service-a
The path prefix `/api` matches the start of `/api/v1`, so the request goes to service-a.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Both services
Why it's wrong here
Only one path matches.
Neither service
Why it's wrong here
The path matches service-a.
service-a
Why this is correct
The path /api matches /api/v1.
Related concept
Static NAT maps one inside address to one outside address.
service-b
Why it's wrong here
Host is app.example.com, not api.example.com.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CKAD NAT questions on configuration and troubleshooting.
