質問 # 174
A threat actor has successfully attacked an organization and gained access to confidential files on a laptop.
What plan should the organization initiate to contain the attack and prevent it from spreading to other network devices?
正解：B
解説：
Once an incident has occurred, the appropriate course of action is to engage the organization's Incident Response (IR) plan. This is a structured approach to contain, analyze, and eradicate threats before they spread across the network.
The Cisco CyberOps Associate study guide emphasizes:
* "Incident response and handling are essential within an organization... The main objective of implementing an incident handling process is to reduce the impact of a cyber-attack, ensure the damages caused are assessed, and implement recovery procedures".
* In particular, the containment phase of IR is focused on isolating the threat and preventing lateral movement or further compromise.
Options such as "root cause" or "attack surface" are relevant at later stages of analysis and mitigation, not immediate containment. Therefore, the correct answer is C.
質問 # 175
Refer to the exhibit.
Which two actions should be taken as a result of this information? (Choose two.)
正解：B、E
解説：
The XML (STIX/CybOX format) details an email-based threat indicator. Specifically:
* The email address contains "@state.gov" (not exact match, so blocking all @state.gov would be overbroad).
* The attachment is a PDF file with a specified MD5 hash: cf2b3ad32a8a4cfb05e9dfc45875bd70.
* The attachment size is 87022 bytes.
From a threat mitigation perspective:
* A is correct: Updating AV to block or flag files matching the malicious hash is a standard response.
* D is correct: The email address context and hash together provide a precise rule for blocking-this prevents false positives.
Incorrect options:
* B overreaches by blocking an entire domain without confirming threat context.
* C would stop all PDFs, which is impractical.
* E is incorrect; there is no indication that the hash appears in the subject line.
質問 # 176

The antivirus software on the endpoint flagged a suspicious file during a routine scan On initial evaluation the file did not match any known signatures in the antivirus database, but exhibited unusual network behavior during dynamic analysis Which step should the analyst take next?
正解：D
