A workstation suddenly begins making SMB connections to many internal servers within a few minutes. What is the best immediate response?
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.
Distractor review
Allow the traffic because SMB is a normal file-sharing protocol.
SMB can be legitimate, but rapid connections to many hosts are not normal and may indicate lateral movement or compromise.
Best answer
Isolate the workstation from the network for containment.
Network isolation limits possible lateral movement and helps stop a compromised host from touching additional systems while the event is investigated.
Distractor review
Delete the local event logs to reduce alert noise.
Deleting logs removes evidence and interferes with investigation. It does not stop the suspicious activity or protect other systems.
Distractor review
Disable all SMB services on every server immediately.
Turning off SMB everywhere is disruptive and too broad for initial containment. The suspicious endpoint should be contained first.
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 SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Isolate the workstation from the network for containment. — A workstation that rapidly contacts many internal systems over SMB is a common sign of lateral movement or worm-like behavior. The best immediate response is to isolate the workstation so it cannot continue scanning or accessing other hosts. Containment should focus on the suspected source first, then the team can determine whether the activity was malicious, misconfigured, or part of an authorized task. Why others are wrong: SMB being common does not make this pattern safe; the volume and spread are suspicious. Deleting logs destroys evidence and is never an appropriate first move. Disabling SMB globally is overly disruptive and does not address the likely infected source in a targeted way.
