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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ingress can route traffic based on the requested hostname
Ingress can route based on host and path, and can terminate TLS. Ingress does not support TCP/UDP directly; it's for HTTP/HTTPS. IngressClass is used to select the Ingress controller. Multiple Ingress resources can coexist.
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
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
An Ingress resource without an IngressClass will not work
Why it's wrong here
It will work if there is a default IngressClass.
✗
Only one Ingress resource can exist per namespace
Why it's wrong here
Multiple Ingress resources are allowed.
✗
Ingress can handle non-HTTP protocols like TCP
Why it's wrong here
Ingress is for HTTP/HTTPS; TCP is handled by Services.
✓
Ingress can route traffic based on the requested hostname
Why this is correct
Host-based routing is a common feature.
Related concept
Static NAT maps one inside address to one outside address.
✓
TLS termination can be configured in the Ingress spec
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
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
How to think about this question
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.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
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
How this comes up in practice
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.
