- A
show ip nat translations
This command lists all current NAT/PAT translations, including inside local, inside global, outside local, and outside global addresses.
- B
show ip nat statistics
This command displays NAT statistics such as total translations, hits, misses, and expiration timers.
- C
show ip nat verbose
Why wrong: This is not a valid Cisco IOS command; the correct verbose option is show ip nat translations verbose.
- D
show running-config | include nat
Why wrong: This shows NAT configuration, not active translations or statistics.
- E
debug ip nat
Why wrong: This is a debug command used for real-time translation events, not for verifying existing translations or statistics.
Question 1,136 of 2,152
Essential NAT Verification Commands for Cisco IOS
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.
Which TWO commands would a network engineer use to verify NAT translations and their statistics on a Cisco IOS router? (Choose TWO.)
Quick Answer
The answer is show ip nat translations and show ip nat statistics. These two commands are correct because they serve distinct but complementary verification roles: show ip nat translations displays the actual active NAT or PAT translation entries in the table, showing which inside local addresses are mapped to which global addresses, while show ip nat statistics provides a summary of translation counters, hits, misses, and configuration details such as the number of expired translations. On the Cisco CCNP ENARSI 300-410 exam, this question tests your ability to differentiate between operational verification and statistical monitoring of NAT, a common topic in the NAT/PAT configuration and troubleshooting section. A frequent trap is confusing show ip nat statistics with the nonexistent show ip nat stats or show ip nat count, so remember that translations shows the table, statistics shows the counters. A helpful memory tip is “Translations for the table, Statistics for the tally.”

Correct answer & explanation
✓
show ip nat translations
The 'show ip nat translations' command displays the current active NAT/PAT translation entries in the translation table, including inside local, inside global, outside local, and outside global addresses. The 'show ip nat statistics' command provides aggregate counters such as total translations, hits, misses, expired translations, and the number of dynamic mappings. Together, these two commands give a complete view of both the active translations and their performance statistics, which is essential for verifying NAT operations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Related concept
Read the scenario before looking for a memorised answer.
- ✗
show ip nat verbose
Why it's wrong here
This is not a valid Cisco IOS command; the correct verbose option is show ip nat translations verbose.
- ✗
show running-config | include nat
Why it's wrong here
This shows NAT configuration, not active translations or statistics.
- ✗
debug ip nat
Why it's wrong here
This is a debug command used for real-time translation events, not for verifying existing translations or statistics.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between verification commands (show) and troubleshooting commands (debug), and candidates mistakenly select 'debug ip nat' because they think it provides statistics, when in fact it is a real-time debugging tool that can impact router performance.
Trap categories for this question
Command / output trap
This is not a valid Cisco IOS command; the correct verbose option is show ip nat translations verbose.
Detailed technical explanation
How to think about this question
NAT translations are stored in a hash table keyed by protocol, inside global IP:port, and outside global IP:port; the 'show ip nat translations' command iterates this table. The statistics counters, such as hits and misses, are incremented in the data plane when a packet matches or fails to match an existing translation entry. In real-world scenarios, a sudden increase in 'misses' in 'show ip nat statistics' can indicate a misconfigured ACL or insufficient dynamic NAT pool addresses, leading to dropped traffic.
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 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.
