質問 # 44
While investigating an alert, an analyst notices that a URL indicator has a related alert from a previous incident. The related alert has the same URL but it resolved to a different IP address.
Which combination of two actions should the analyst take to resolve this issue? (Choose two.)
- A. Expire the URL indicator
- B. Enrich the URL indicator
- C. Remove the relationship between the URL and the older IP address
- D. Enrich the IP address indicator associated with the previous alert
正解：B、C
解説：
The correct answers areB (Remove the relationship between the URL and the older IP address)andD (Enrich the URL indicator).
* B:If the same URL now resolves to a new IP, but old relationships are still present, the analyst should remove the outdated relationshipbetween the URL indicator and the previous IP address to avoid confusion in future investigations.
* D:Enriching the URL indicatorwill update its context, relationships, and threat intelligence attributes, ensuring the indicator reflects the most accurate and current data.
"Analysts should remove obsolete relationships between indicators and enrich indicators to update contextual data as network conditions change (e.g., when a URL points to a new IP address)." Document Reference:XSIAM Analyst ILT Lab Guide.pdf Page:Page 36-37 (Threat Intel Management section)

質問 # 58
SCENARIO:
A security analyst has been assigned a ticket from the help desk stating that users are experiencing errors when attempting to open files on a specific network share. These errors state that the file format cannot be opened. IT has verified that the file server is online and functioning, but that all files have unusual extensions attached to them.
The security analyst reviews alerts within Cortex XSIAM and identifies malicious activity related to a possible ransomware attack on the file server. This incident is then escalated to the incident response team for further investigation.
Upon reviewing the incident, the responders confirm that ransomware was successfully executed on the file server. Other details of the attack are noted below:
* An unpatched vulnerability on an externally facing web server was exploited for initial access
* The attackers successfully used Mimikatz to dump sensitive credentials that were used for privilege escalation
* PowerShell was used on a Windows server for additional discovery, as well as lateral movement to other systems
* The attackers executed SystemBC RAT on multiple systems to maintain remote access
* Ransomware payload was downloaded on the file server via an external site "file io" QUESTION STATEMENT:
The incident responders are attempting to determine why Mimikatz was able to successfully run during the attack.
Which exploit protection profile in Cortex XSIAM should be reviewed to ensure it is configured with an Action Mode of Block?
- A. Logical Exploits Protection
- B. Browser Exploits Protection
- C. Known Vulnerable Process Protection
- D. Operating System Exploit Protection
正解：C
解説：
The correct answer isC - Known Vulnerable Process Protection.
Known Vulnerable Process Protectionin Cortex XSIAM is specifically designed to block or restrict execution of well-known attack tools and processes such asMimikatz. This profile allows you to enforce an Action Mode of "Block" to prevent such tools from running, even if they are executed as part of a privilege escalation or credential dumping attack.
"The Known Vulnerable Process Protection profile can be configured to block processes like Mimikatz, preventing credential dumping tools from running on protected endpoints." Document Reference:EDU-270c-10-lab-guide_02.docx (1).pdf Page:Page 16 (Malware and Exploit Profile Management section)
質問 # 59

- D. Use the xdm.process table
正解：B、D

正解：C、D
質問 # 62
A Cortex XSIAM analyst in a SOC is reviewing an incident involving a workstation showing signs of a potential breach. The incident includes an alert from Cortex XDR Analytics Alert source "Remote service command execution from an uncommon source." As part of the incident handling process, the analyst must apply response actions to contain the threat effectively.
Which initial Cortex XDR agent response action should be taken to reduce attacker mobility on the network?
- A. Block IP Address: Prevent future connections to the IP from the workstation
- B. Remove Malicious File: Delete the malicious file detected
- C. Isolate Endpoint: Prevent the endpoint from communicating with the network
- D. Terminate Process: Stop the suspicious processes identified
正解：C
解説：
The correct answer isA - Isolate Endpoint.
The most effective initial response to contain a breach and reduce attacker mobility is toisolate the endpoint.
This action ensures that the compromised machine can no longer communicate with the network or external systems, effectively cutting off lateral movement and exfiltration by attackers, while still allowing controlled response operations.
"Isolate Endpoint is the primary response action used to immediately contain a threat by severing all network communication, thus limiting attacker movement during active incidents." Document Reference:EDU-270c-10-lab-guide_02.docx (1).pdf Page:Page 40 (Incident Handling/SOC section)
質問 # 63
What triggers the automatic creation of an incident in Cortex XSIAM?
Response:
- A. Completion of a playbook
- B. Detection of a defined IOC, BIOC, or correlation rule match
- C. Manual alert starring
- D. A correlation rule threshold breach
正解：B
質問 # 64

- B. Use syslog to flush logs
- C. Create a block rule
- D. Enrich incidents with the indicator
正解：C、D
