- A
The administrator did not preserve the log evidence for forensic analysis.
Why wrong: Preserving logs is important but does not stop ongoing access.
- B
The administrator neglected to perform a full system scan for malware.
Why wrong: Scanning is part of eradication, not immediate containment.
- C
The administrator did not isolate the server from the network.
Isolation prevents further access and contains the threat.
- D
The administrator failed to notify the data owner about the incident.
Why wrong: Notification is important but does not stop the attack.

Incident Response Containment: Isolate the Server
This SSCP practice question tests your understanding of sscp exam topics. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 security administrator notices that a critical server's event log shows repeated failed login attempts from an internal IP address that normally does not generate any traffic. The administrator immediately blocks the IP at the firewall and resets the account password. However, the incident response team later determines that the attacker had already gained access to the server. What is the MOST likely reason the administrator's actions were insufficient?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"most likely"Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Clue:
"immediately / without restart"Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
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 administrator did not isolate the server from the network.
Option C is correct. The administrator's actions—blocking the IP at the firewall and resetting the password—were insufficient because the attacker had already gained access to the server. Isolating the server (e.g., disconnecting it from the network) would have severed the attacker's active connection and prevented further compromise. Option A is wrong because preserving logs is important for investigation but does not stop an ongoing breach. Option B is wrong because a malware scan is a remediation step after containment. Option D is wrong because notifying the data owner addresses notification requirements but does not directly contain the threat.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
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 security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
