Full question →mediummultiple choiceObjective-mapped
Users in a branch office report intermittent connectivity to the corporate data center. A technician runs a continuous ping from a workstation to the data center server and observes packet loss after the third hop. Which command should the technician run next to identify the specific router causing the issue?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
ping -n 1000 server_ip
Ping only tests end-to-end connectivity and cannot identify which hop is causing packet loss.
B
Best answer
tracert server_ip
Tracert lists each hop along the path and displays packet loss per hop, allowing the technician to isolate the faulty router.
C
Distractor review
nslookup server_ip
Nslookup is used for DNS resolution, not for path analysis.
D
Distractor review
ipconfig /all
Ipconfig shows local IP configuration, not the network path to a remote host.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this N10-009 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: tracert server_ip — Tracert (or traceroute) shows the path packets take to a destination and identifies each hop's response time and packet loss. This will pinpoint which router along the path is dropping packets. Ping only tests end-to-end, and nslookup and ipconfig are not used for path tracing.
