Question 454 of 2,152
NAT and PATeasyMultiple ChoiceObjective-mapped

Quick Answer

The answer is dynamic NAT without overload, using a pool of addresses. This is correct because the output of **show ip nat translations** displays two distinct inside global addresses (203.0.113.1 and 203.0.113.2) mapped one-to-one to their respective inside local addresses, with no port numbers listed under the "Pro" column, which confirms that Port Address Translation (overload) is not in use. On the Cisco CCNP ENARSI 300-410 exam, this scenario tests your ability to **interpret show ip nat translations** output and differentiate between dynamic NAT with a pool and PAT; a common trap is assuming that multiple translations always mean overload, but the absence of protocol and port entries signals a true pool-based translation. Remember the memory tip: "No port, no overload—each host gets its own global address from the pool."

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 to verify NAT after a fix:

R1# show ip nat translations

Pro Inside global Inside local Outside local Outside global --- 203.0.113.1 10.1.1.1 192.168.1.1 192.168.1.1 --- 203.0.113.2 10.1.1.2 192.168.1.2 192.168.1.2

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Dynamic NAT without overload, using a pool of addresses.

The output shows two dynamic translations with different inside global addresses, indicating a pool of addresses is used without PAT (overload).

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.

  • Dynamic NAT without overload, using a pool of addresses.

    Why this is correct

    Each inside host gets a unique global address from a pool.

    Clue confirmation

    The clue word "most likely" in the question point toward this answer.

    Related concept

    Static NAT maps one inside address to one outside address.

  • Static NAT for each host.

    Why it's wrong here

    Static NAT would show the same mapping always.

  • PAT with a single address.

    Why it's wrong here

    PAT would show the same global address with different ports.

  • NAT is not configured.

    Why it's wrong here

    Translations exist.

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

    Static NAT would show the same mapping always.

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.
