- A
The 'ip domain-lookup' command is disabled by default on Cisco IOS routers.
Why wrong: Incorrect. The 'ip domain-lookup' command is enabled by default. It must be explicitly disabled with 'no ip domain-lookup' if DNS resolution is not desired.
- B
The 'ip name-server' command can specify up to six DNS servers.
Correct. The 'ip name-server' command allows configuring up to six DNS server addresses. The router will query them in order.
- C
The 'ip domain-list' command adds a domain suffix to the search list for DNS queries.
Correct. The 'ip domain-list' command appends a domain suffix to unqualified hostnames (those without a dot) during DNS resolution. Multiple domain lists can be configured.
- D
The 'ip host' command creates a dynamic DNS entry that can be overwritten by a DNS server.
Why wrong: Incorrect. The 'ip host' command creates a static host entry in the local host table. Static entries are not overwritten by DNS responses; they take precedence over dynamic resolution.
- E
The 'show hosts' command displays only statically configured host entries.
Why wrong: Incorrect. The 'show hosts' command displays both static and dynamically learned (via DNS) host entries, including their addresses and flags indicating how they were learned.
Quick Answer
The correct answer is that the 'ip domain-list' command adds a domain suffix to the search list for DNS queries. This is true because when a user pings an unqualified hostname—one without a dot—the router appends each suffix from the domain-list in order until a resolution succeeds, effectively expanding the search domain. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding of how DNS resolution behaves on IOS devices, often appearing in a multiple-choice question that pairs 'ip domain-list' with 'ip domain-lookup' or 'ip name-server'. A common trap is confusing 'ip domain-list' with 'ip domain-name', which sets only a single default suffix rather than a search list. Remember that 'ip domain-lookup' must be enabled for any dynamic DNS queries to work, and 'ip name-server' points to the actual resolver. Memory tip: think of "list" as a grocery list of suffixes to try, while "name" is just one item on that list.
300-410 Device Management Practice Question
This 300-410 practice question tests your understanding of device management. 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 statements about the 'ip domain-lookup' and DNS configuration on a Cisco IOS router are true? (Choose TWO.)
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
The 'ip name-server' command can specify up to six DNS servers.
The 'ip domain-lookup' command enables DNS resolution; it is enabled by default. The 'ip name-server' command specifies DNS servers. The 'ip domain-list' command adds a domain suffix to be appended to unqualified names. The 'ip host' command creates a static host entry. The 'show hosts' command displays both static and dynamically learned DNS entries. The 'ip domain-lookup' must be enabled for dynamic DNS resolution to work.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 practitioner preparing for the 300-410 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
