Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A security analyst detects unusual outbound traffic from a workstation that appears to be communicating with a known malicious IP address. The analyst immediately isolates the workstation from the network. Which of the following is the NEXT step in the incident response process according to NIST SP 800-61?
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
Best answer
Eradication
Eradication is the correct next step. After containment, the incident response team must remove the threat's root cause (e.g., malware, backdoors) to prevent recurrence. This logically follows isolation of the affected system.
B
Distractor review
Recovery
Recovery is not the next step. Recovery restores systems to normal operation after eradication has been completed. Attempting recovery before eradication could leave the system vulnerable to reinfection.
C
Distractor review
Containment
Containment has already been performed by isolating the workstation. Repeating containment would be redundant and delay progression to the next phase.
D
Distractor review
Lessons Learned
Lessons Learned is the final phase of incident response, conducted after recovery. It involves post-incident review to improve future responses, not immediate next steps.
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: Eradication — According to the NIST SP 800-61 incident response process, after containing an incident (e.g., isolating a workstation), the next phase is eradication. Eradication involves eliminating the root cause of the incident, such as removing malware, patching vulnerabilities, or disabling compromised accounts. Recovery follows eradication, and lessons learned occurs after recovery.
