Cisco Conducting Forensic Analysis & Incident Response Using Cisco Technologies for CyberOps Sample Questions (Q16-Q21):

NEW QUESTION # 16
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?

A. Review the database.log file in the program files directory for database errors
B. Check the Memory.dmp file in the Windows directory for memory leak indications
C. Examine the system.cfg file in the Windows directory for improper system configurations
D. Analyze the PageFile.sys file in the System Drive and the Virtual Memory configuration

Answer: D

Explanation:
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.

NEW QUESTION # 17
Refer to the exhibit.

What should an engineer determine from this Wireshark capture of suspicious network traffic?

A. There are signs of SYN flood attack, and the engineer should increase the backlog and recycle the oldest half-open TCP connections.
B. There are signs of a DNS attack, and the engineer should hide the BIND version and restrict zone transfers as a countermeasure.
C. There are signs of a malformed packet attack, and the engineer should limit the packet size and set a threshold of bytes as a countermeasure.
D. There are signs of ARP spoofing, and the engineer should use Static ARP entries and IP address-to-MAC address mappings as a countermeasure.

Answer: A

NEW QUESTION # 18
A security team received reports of users receiving emails linked to external or unknown URLs that are non- returnable and non-deliverable. The ISP also reported a 500% increase in the amount of ingress and egress email traffic received. After detecting the problem, the security team moves to the recovery phase in their incident response plan. Which two actions should be taken in the recovery phase of this incident? (Choose two.)

A. scan hosts with updated signatures
B. verify the breadth of the attack
C. request packet capture
D. remove vulnerabilities
E. collect logs

Answer: A,D

Explanation:
In therecovery phase, the goal is to restore affected systems to normal operations and ensure the threat has been completely eradicated. According to the CyberOps Associate guide:
"This phase may include restoring data from clean backups, replacing compromised systems, and the re- installation of the Operating System (OS) and applications".
Also:
"During recovery, scanning hosts with updated antivirus and removing vulnerabilities ensures systems do not get reinfected".

NEW QUESTION # 19
A new zero-day vulnerability is discovered in the web application. Vulnerability does not require physical access and can be exploited remotely. Attackers are exploiting the new vulnerability by submitting a form with malicious content that grants them access to the server. After exploitation, attackers delete the log files to hide traces. Which two actions should the security engineer take next? (Choose two.)

A. Validate input upon submission.
B. Update web application to the latest version.
C. Block connections on port 443.
D. Enable file integrity monitoring.
E. Install antivirus.

Answer: A,D

Explanation:
* Input validation (A) is a critical countermeasure to defend against command injection and related vulnerabilities, as discussed in the Cisco guide. Proper validation ensures that malicious commands or payloads are not accepted or executed by the web application.
* File integrity monitoring (E) helps detect unauthorized changes such as log deletion or binary modification, making it a crucial tool in recognizing and investigating tampering attempts.Blocking port
443 (B) would disable HTTPS and is not a practical solution. Antivirus (C) does not prevent form- based application attacks, and merely updating the application (D) may not be sufficient without addressing the underlying input validation flaw.

NEW QUESTION # 20
A threat intelligence report identifies an outbreak of a new ransomware strain spreading via phishing emails that contain malicious URLs. A compromised cloud service provider, XYZCloud, is managing the SMTP servers that are sending the phishing emails. A security analyst reviews the potential phishing emails and identifies that the email is coming from XYZCloud. The user has not clicked the embedded malicious URL.
What is the next step that the security analyst should take to identify risk to the organization?

A. Delete email from user mailboxes and update the incident ticket with lessons learned.
B. Create a detailed incident report and share it with top management.
C. Find any other emails coming from the IP address ranges that are managed by XYZCloud.
D. Reset the reporting user's account and enable multifactor authentication.

Answer: C

Explanation:
Since the phishing email originates from a known compromised cloud provider (XYZCloud), the correct immediate action for the security analyst is to determine the broader scope of exposure. This involves checking whether other users in the organization received similar emails from the same potentially malicious source. Therefore, querying for emails from theIP address rangesorSMTP domainslinked to XYZCloud is essential for identifying other possible attack vectors.
This step aligns with the containment phase of the incident response lifecycle, as outlined in theCyberOps Technologies (CBRFIR) 300-215 study guide, where threat hunting and log analysis are used to determine the extent of compromise and prevent lateral movement or further exposure. Only after the scope is understood should remediation or reporting actions follow.
