NEW QUESTION # 105
Refer to the exhibit.
An engineer analyzes a suspicious email. Which two actions should be taken? (Choose two.)
Answer: D,E
Explanation:
The STIX/CybOX indicator identifies two actionable observables: a sender address containing @site.org and a .doc file with the specified SHA-256 hash. Blocking incoming mail from the identified malicious domain contains the known delivery source, while adding the exact SHA-256 value to endpoint or antivirus controls blocks the documented malicious file. The block should later be reviewed because domain reputation and ownership can change. Option A incorrectly treats an XML schema attribute as email subject text. Option B names a nonexistent SHA128 algorithm and does not match the indicator. Blocking every document attachment is excessively broad and would disrupt legitimate business traffic. CBRFIR Incident Response Processes objective 5.5 requires analysis of threat intelligence in STIX and TAXII formats. OASIS defines STIX as a machine-readable language for exchanging indicators and other cyber-threat intelligence. OASIS STIX 2.1
NEW QUESTION # 106
A security team is discussing lessons learned and suggesting process changes after a security breach incident.
During the incident, members of the security team failed to report the abnormal system activity due to a high project workload. Additionally, when the incident was identified, the response took six hours due to management being unavailable to provide the approvals needed. Which two steps will prevent these issues from occurring in the future? (Choose two.)
Answer: A,C
Explanation:
According to theCyberOps Technologies (CBRFIR) 300-215 study guide, during thepost-incident activity phase, it is critical to analyze lessons learned and update processes to ensure quicker and more efficient response in the future. Specifically:
* Introducing a priority rating for incident response workloads(A) helps address the issue of team members being occupied with other tasks and unable to prioritize abnormal system activity. This ensures incidents are handled based on severity, not just workload.
* Creating an executive team delegation plan(D) addresses the issue of delays due to unavailability of management for approvals. It ensures alternative decision-makers are available for swift action.
These strategies are based on the NIST SP 800-61 Rev. 2 recommendations and are highlighted in the Cisco guide's post-incident activity phase (page 418), which emphasizeslessons learnedand how to reduce detection and response times for future incidents.
Reference:CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter: Dealing with Incident Response, Post-Incident Activity, page 418.
NEW QUESTION # 107
Refer to the exhibit.
What do these artifacts indicate?
Answer: B
Explanation:
From the exhibit, the first artifact (PE32 executable fromsyracusecoffee.com) and the second artifact (HTML fromqstride.com) suggest astaged malware deliverymethod. The executable and the HTML file are linked to different domains, often indicating redirection or multi-stage infection strategies, which is common in phishing or malvertising campaigns.
The Cisco guide explains this tactic as:"One file may appear benign but can initiate downloads or connections to external resources to fetch additional payloads or redirect users". This pattern of domain redirection strongly supportsOption B.
NEW QUESTION # 108
Refer to the exhibit.
What is occurring within the exhibit?
Answer: C
Explanation:
The Wireshark capture shows a series of HTTP requests and responses:
The client (10.1.21.101) sends a GET request for /Lk9tdZ.
The server (209.141.51.196) responds with HTTP/1.1 302 Found, which is a standard HTTP status code indicating a redirection.
The subsequent GET request from the client is for /files/1.bin, which indicates it followed the redirect.
This behavior confirms that the server is issuing an HTTP 302 redirect from the initial request path /Lk9tdZ to
/files/1.bin. This is often observed in malware command-and-control behavior or file download staging.
Option A is incorrect: 302 is a status code, not a data size.
Option C is incorrect: port 49723 is a source/destination ephemeral port, not a redirect target.
Option D is incorrect: communication is over HTTP, not HTTPS (which would indicate encryption).
Reference: CyberOps Technologies (CBRFIR) 300-215 study guide, Chapter on Network Traffic Analysis and HTTP Status Code Interpretation.
NEW QUESTION # 109
Refer to the exhibit.
import requests
def check_status(url):
response = requests.get(url)
return response.status_code
In which programming language is the code written, and what is it trying to accomplish?
Answer: D
Explanation:
The syntax identifies Python: it uses import, defines a function with def, terminates the function header with a colon, and relies on indentation rather than braces. The requests library sends an HTTP GET request to the supplied URL, and response.status_code returns the server's HTTP result code.
Repeated execution can test whether a website responds successfully, which makes "website-uptime monitor" the closest description among the choices. Strictly, this short function performs one availability check; a production monitor would add scheduling, timeouts, exception handling, expected- status logic, logging, and alerting. It neither parses a dataset nor implements a content-management system, and it does not write response content to a file. Option D is therefore correct. This is within CBRFIR objectives 2.4 and 2.5. The official Requests quick-start documentation demonstrates requests.
get() and status_code in this exact role.
