200-201 Cisco Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) Free Practice Exam Questions (2026 Updated)

 To investigate the callouts made post infection, it’s essential to know where the callouts were made to (domain names) and from which host IP addresses they originated. This information can help trace back the source and destination, aiding in understanding the nature of the callouts. References: https://www.cisco.com/c/en/us/td/docs/security/firepower/60/configuration/guide/fpmc-config-guide-v60/Working_with_Indicators_of_Compromise.html

 In the context of Linux systems, each active program is tracked using a process identification number (PID). The PID is a unique number that the system uses to refer to a specific process, which is an instance of an executed program. This allows the system and the SOC analyst to monitor and manage different processes, including those initiated by users, the system itself, or by applications.

In this scenario, the threat actor refers to the individuals or entities responsible for the attack that resulted in a breach of assets and sensitive information. The receptionist received a threatening call but did not take action, leading to an actual breach within 48 hours. References: The explanation is inferred from general cybersecurity knowledge as specific details are not provided in the Cisco Cybersecurity documents linked.

The scenario described involves an attacker conducting an aggressive ARP scan followed by multiple SSH Server Banner and Key Exchange Initiations. The lack of visibility into the encrypted data transmitted over the SSH channel suggests that the attacker may have gained access by brute-forcing the SSH service. This method involves attempting numerous combinations of usernames and passwords until the correct credentials are found, allowing unauthorized access to the server.

 Input sanitization involves cleaning up user input before processing it, ensuring that it does not contain malicious code intended for buffer overflow attacks or other types of security breaches. References := New Cybersecurity Skills

Social engineering techniques often involve manipulating individuals into divulging confidential information or performing actions that compromise security. Phishing involves sending fraudulent messages (often emails) that appear to be from reputable sources with the goal of stealing sensitive data or installing malware. Pharming redirects the traffic of a legitimate website to another fraudulent website without the user’s knowledge, aiming to collect the user’s credentials. References := Cisco Cybersecurity Source Documents

Upgrading to TLS v1.3 is recommended because it eliminates outdated cryptographic functions and reduces the risk of downgrade attacks, which can occur when attackers force connections to use weaker encryption. TLS v1.3 only supports secure cipher suites and algorithms, enhancing the security of communications.

The weaponization step in the Cyber Kill Chain model involves creating or repurposing malware based on the information gathered during reconnaissance to exploit vulnerabilities in the target’s system. This step culminates in the preparation of the malware to be delivered to the victim2.

Cyber Kill Chain

A threat actor is a person or entity that is responsible for an incident that impacts or has the potential to impact an organization’s security. A threat actor can have various motivations, such as financial gain, espionage, sabotage, or activism. A threat actor can use various methods, such as malware, phishing, denial-of-service, or social engineering, to perform an attack. A threat actor is not the same as a malware author, a bug bounty hunter, or a direct competitor, although they may be related or associated. A malware author is someone who creates malicious software that can be used by threat actors. A bug bounty hunter is someone who finds and reports vulnerabilities in software or systems for a reward. A direct competitor is someone who offers similar products or services as the organization and may seek to gain an advantage over it. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 87; CNSSI 4009-2015, page 77

Defense-in-depth is a security strategy where multiple layers of defense are placed throughout an information technology (IT) system. It addresses physical, technical, and administrative controls to provide redundancy and ensure that if one layer fails, others will be in place to thwart an attack. References: Cisco Tech Roles - CyberOps Engineer

User interaction is any event that requires the user to perform an action that enables or facilitates a cyberattack. Opening a malicious file is an example of user interaction, as it can trigger the execution of malicious code or malware that can compromise the system or network. Gaining root access, executing remote code, and reading and writing file permissions are not user interactions, but rather actions that can be performed by an attacker after exploiting a vulnerability or bypassing security controls. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, More than 99% of cyberattacks rely on human interaction

 Event Code 4625 in Windows logs indicates a failed logon attempt. This could be a sign of someone trying to guess the credentials of a valid user account by repeatedly trying different passwords or usernames. This is known as a brute force attack and can be used to gain unauthorized access to a system or network. References: https://www.cisco.com/c/en/us/td/docs/security/ise/2-4/admin_guide/b_ise_admin_guide_24/b_ise_admin_guide_24_new_chapter_01110.html

 SYN flood and teardrop are two types of denial-of-service (DoS) attacks, which aim to disrupt the availability of a service or a system by overwhelming it with malicious traffic or requests. A SYN flood attack exploits the TCP three-way handshake process by sending a large number of SYN packets to the target’s port, without completing the connection. This causes the target to allocate resources for half-open connections, eventually exhausting its memory or bandwidth. A teardrop attack exploits the IP fragmentation process by sending malformed or overlapping IP fragments to the target, causing it to crash or reboot when trying to reassemble them. References := Cisco Cybersecurity Operations Fundamentals, Module 1: Security Concepts, Lesson 1.3: Common Network Application Operations and Attacks, Topic 1.3.4: Denial-of-Service Attacks

 The average time taken by a Security Operations Center (SOC) to detect and resolve incidents is a critical metric for evaluating its effectiveness and scope. This metric reflects the SOC’s efficiency in identifying security threats and its ability to respond and mitigate those threats promptly. It encompasses the entire incident lifecycle, from initial detection to final resolution, providing a comprehensive measure of the SOC’s performance1.

 In the context of phishing emails, the threat actor is the entity that is responsible for initiating the threat, which in this case is the sender of the phishing emails. The sender is impersonating the HR department to deceive the receiver into believing that the emails are legitimate

 HTTPS traffic is difficult to screen because it is encrypted using the SSL/TLS protocol, which secures the data in transit between the client and the server. This encryption ensures that any intercepted traffic cannot be easily read or tampered with by third parties. Screening or inspecting this encrypted traffic would require decrypting it, which poses significant challenges and potential security risks12.

The concept of HTTPS and its implications on traffic screening are discussed in various cybersecurity resources, including Cisco’s cybersecurity training materials3.

Cloudflare provides an explanation of HTTPS inspection and the challenges associated with it

Delivery is the fourth phase of the cyber kill chain, which is a model to describe the stages of a cyberattack. Delivery refers to the transmission of the weaponized payload to the target system, such as via email attachments, web links, USB drives, or network connections. Delivery does not necessarily imply successful installation or execution of the payload, which are subsequent phases of the kill chain. References := Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 31.

 In the context of incident response, the detection step involves identifying potential security incidents. The Security Operation Center (SOC) Analyst, which in this case is Employee 4, is typically responsible for monitoring and analyzing security alerts to detect suspicious activities such as brute-force attempts. Therefore, Employee 4 would be the stakeholder responsible for the incident response detection step. References: The role of a SOC Analyst in incident response is outlined in cybersecurity frameworks and bestpractices, which describe the responsibilities of various stakeholders in detecting and responding to security incidents.
