The correct statement is that static NAT is configured for host 10.0.0.10 to 192.0.2.10. This is confirmed by the show ip nat translations output, which displays a single static mapping with an Inside local address of 10.0.0.10 and an Inside global address of 192.0.2.10, while the Outside local and Outside global fields are empty—a hallmark of static NAT. The show ip nat statistics output reinforces this by reporting exactly one static translation and zero dynamic translations, with five hits indicating successful packet translation. On the Cisco CCNP ENARSI 300-410 exam, this scenario tests your ability to interpret NAT translation tables and distinguish static from dynamic entries; a common trap is confusing the empty Outside columns with a missing configuration, but static NAT only maps inside addresses, leaving those fields blank. Remember the memory tip: “Static is local-to-global, no outside involved”—if the Outside columns are dashes, it’s a static one-to-one mapping, not dynamic or PAT.
300-410 NAT and PAT Practice Question
This 300-410 practice question tests your understanding of nat and pat. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 network engineer runs the following command on Router R1:
R1# show ip nat translations
Pro Inside global Inside local Outside local Outside global
--- 192.0.2.10 10.0.0.10 --- ---
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Static NAT is configured for host 10.0.0.10 to 192.0.2.10.
The output shows a single static NAT translation. The statistics confirm 1 static translation and 0 dynamic. This is a simple static NAT mapping.
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.
✓
Static NAT is configured for host 10.0.0.10 to 192.0.2.10.
Why this is correct
The translation shows a static mapping (no protocol, and statistics confirm static).
Related concept
Static NAT maps one inside address to one outside address.
PAT is translating multiple hosts to the same global address.
Why it's wrong here
Only one translation exists, and it is static.
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.
Trap categories for this question
Command / output trap
The statistics show 0 dynamic translations.
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.
