Question 789 of 2,152

NAT and PAT →mediumDrag & DropObjective-mapped

Quick Answer

The answer is to test connectivity with an extended ping from inside as the final step. This order is correct because NAT verification on Cisco IOS must follow a logical top-down methodology: you first check for the existence of translations with show ip nat translations, then verify interface assignments with show ip nat statistics, review detailed active translations and counters for drops or failures, and only after confirming the configuration is sound do you test end-to-end reachability with an extended ping sourced from an inside address. On the CCNP ENARSI 300-410 exam, this drag-and-drop task tests your understanding that troubleshooting begins with control-plane verification before moving to data-plane testing—a common trap is jumping straight to a ping, which can fail due to misconfigured ACLs or overload pools even when translations appear correct. Remember the mnemonic TIVP: Translations, Interfaces, Verification (statistics), then Ping.

300-410 NAT and PAT Practice Question

This 300-410 practice question tests your understanding of nat and pat. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

Drag and drop the steps to verify and validate NAT and PAT operational state into the correct order, from first to last.

Correct answer & explanation

Display show ip nat translations summary

Verification should start with a high-level overview of translations, then check for active translations with details, then verify interface configurations, then confirm statistics for drops or failures, and finally test end-to-end connectivity.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.

What to study next

Got this wrong? Here's your next step.

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 300-410 NAT questions on configuration and troubleshooting.
