Cisco Conducting Forensic Analysis & Incident Response Using Cisco Technologies for CyberOps 認定 300-215 試験問題 (Q81-Q86):

質問 # 81
Refer to the exhibit.

Which element in this email is an indicator of attack?

正解：D

解説：
According to the Cisco Certified CyberOps Associate guide (Chapter 5 - Identifying Attack Methods), attachments in emails-especially with file extensions like.xlsm-are high-risk indicators when analyzing suspicious or phishing emails. Malicious actors often use macro-enabled Excel files (.xlsm) as a payload delivery mechanism for malware or other exploits. These attachments are typically disguised as legitimate content such as refunds or invoices to trick the recipient into opening them.
The presence of"Card_Refund_18_6913.xlsm"is a strongIndicator of Compromise (IoC), as.xlsmfiles can contain VBA macros capable of executing malicious code. This matches exactly with examples provided in the study material discussing how macro-based payloads are delivered and recognized.
Hence,option Cis the most direct indicator of attack in this email.


質問 # 82
Data has been exfiltrated and advertised for sale on the dark web. A web server shows:
* Database unresponsiveness
* PageFile.sys changes
* Disk usage spikes with CPU spikes
* High page faults
Which action should the IR team perform on the server?

正解：D

解説：
The combination of CPU spikes, disk usage peaks, and fluctuating PageFile.sys indicates excessive virtual memory paging, which may be a sign of malicious memory or file access behavior. PageFile.sys is part of the virtual memory system, and analyzing it can reveal which processes or payloads are consuming unusual amounts of memory, especially during exfiltration events.


質問 # 83
Refer to the exhibit.

What is occurring?

正解：D

解説：
Comprehensive and Detailed Explanation:
The log entry contains the following key elements:
The timestamp: (04/Jan/2022:20:18:06 +0000)
HTTP method and URI: " GET /%60%60%60%60%60%60/ HTTP/2.0 "
HTTP status code: 404
User-Agent: Mozilla/5.0 ... Firefox/95.0
The status code 404 indicates that the requested resource was not found on the server. This is a standard HTTP response that signifies the server could not locate the requested URI (in this case, likely due to a malformed or invalid path /\`````/, where %60 is the URL-encoded form of the backtick character " " ).
There is no clear evidence of SQL injection, WAF detection, or redirection in this log. The use of encoded backticks may suggest probing behavior, but the log does not show a definitive attack signature.
Therefore, the correct interpretation is:
The answer: D. The requested page was not found.


質問 # 84
Refer to the exhibit.

An HR department submitted a ticket to the IT helpdesk indicating slow performance on an internal share server. The helpdesk engineer checked the server with a real-time monitoring tool and did not notice anything suspicious. After checking the event logs, the engineer noticed an event that occurred 48 hour prior. Which two indicators of compromise should be determined from this information? (Choose two.)

正解：B、D


質問 # 85
Refer to the exhibit.

Which determination should be made by a security analyst?

正解：B

解説：
The XML structure shows that:
* The file namestarts with:"Final Report"
* The file extensionequals:"doc.exe"
Together, this forms"Final Report.doc.exe"- a knowndouble-extensiontechnique used todisguise executablesas benign documents. This is a red flag in email forensics, commonly linked tomalware distribution, and explicitly covered in the Cisco CyberOps study material as a typicalevasion methodfor malicious attachments.
