NEW QUESTION # 105
Which of the following describes the purpose of a firewall in network infrastructure?
- A. To regulate the flow of data between different network segments
- B. To provide high-speed connectivity between different networks
- C. To identify and prevent unauthorized access to the network
- D. To monitor network traffic for potential security threats
Answer: A
Explanation:
A firewall is a network security device that is designed to monitor and control the incoming and outgoing network traffic. It acts as a barrier between different network segments, regulating the flow of data according to predefined security policies. Firewalls help to prevent unauthorized access to the network by allowing only authorized traffic and blocking any potentially harmful traffic.

NEW QUESTION # 109
What is privilege escalation in the context of cybersecurity?
- A. The act of elevating one's user account privileges to gain higher levels of access
- B. The process of gaining unauthorized access to a system
- C. The method of stealing sensitive information from a compromised system
- D. The technique used to bypass firewall protections
Answer: A
Explanation:
Privilege escalation refers to the process of gaining higher levels of access or permissions than originally authorized. This can be achieved by exploiting vulnerabilities or weaknesses in a system, such as a software flaw or misconfiguration. By escalating privileges, an attacker can gain more control and access to sensitive data or critical system resources. It is a serious security concern and is commonly used by attackers to broaden their scope of unauthorized activities within a compromised system or network. Implementing strong access controls and regular security updates can help mitigate the risk of privilege escalation.
NEW QUESTION # 110
Which of the following is an example of a secure remote access technology?
- A. SSH
- B. SNMP
- C. FTP
- D. Telnet
Answer: A
Explanation:
SSH (Secure Shell) is a secure remote access protocol that provides encrypted communication between remote devices. Unlike Telnet, which transmits data in plaintext, SSH encrypts the data, making it more secure for remote access to devices or systems. FTP (File Transfer Protocol) and SNMP (Simple Network Management Protocol) are not specifically designed for remote access and do not provide the same level of security as SSH.
NEW QUESTION # 111
What is the primary purpose of packet captures in identifying suspicious events in a cybersecurity context?
- A. To encrypt network traffic and secure sensitive information.
- B. To analyze network traffic and identify potential indicators of compromise.
- C. To backup network configurations and restore them in case of failure.
- D. To monitor network devices and perform vulnerability assessments.
Answer: B
Explanation:
Packet captures are used to capture and record network traffic, allowing cybersecurity professionals to inspect the packets and analyze the network traffic for potential indicators of compromise (IOCs). By examining the packets, analysts can check for suspicious patterns or anomalies, identify malicious payloads, or detect unauthorized access attempts. Packet captures are a valuable tool in incident response, as they help identify and investigate suspicious events in a network.
NEW QUESTION # 112
Why are data backups important in a cybersecurity strategy?
- A. To recover from physical hardware failures
- B. To track changes made to critical system files
- C. To analyze historical data for identifying security incidents
- D. To prevent unauthorized access to sensitive information
Answer: A
Explanation:
Data backups are essential in a cybersecurity strategy primarily to ensure the ability to recover from physical hardware failures, such as server crashes, disk failures, or natural disasters. Regularly backing up critical data helps organizations restore their systems and resume normal operations in case of hardware failures or any other catastrophic events that may result in data loss.
NEW QUESTION # 113
Which of the following best describes asset management in the context of cybersecurity?
- A. Managing network infrastructure
- B. Tracking software licenses
- C. Identifying and protecting valuable resources
- D. Monitoring user activity

Explanation:
Asset management in a cybersecurity context involves identifying and protecting valuable resources within an organization. This includes identifying critical systems, data, and information that need to be protected from unauthorized access, modification, or destruction.
NEW QUESTION # 114
What is the purpose of using an application firewall in a cybersecurity setup?
- A. To perform vulnerability scanning of applications
- B. To block malicious incoming requests and attacks aimed at the application
- C. To encrypt network traffic between applications
- D. To increase the speed and performance of applications
Answer: B
Explanation:
An application firewall, also known as a web application firewall (WAF) or application-level firewall, is designed to protect web applications from various attacks, such as cross-site scripting (XSS), SQL injection, and distributed denial-of-service (DDoS) attacks. It analyzes the incoming traffic and blocks malicious requests, protecting the application and its underlying infrastructure. Encryption, speed enhancement, and vulnerability scanning are not primary functions of an application firewall.
NEW QUESTION # 115
What is the main motivation for attackers to conduct cyber attacks?
- A. Financial gain
- B. Revenge
- C. Curiosity
- D. Knowledge
Answer: A
Explanation:
The primary motivation for many cyber attackers is financial gain. By conducting cyber attacks, attackers may aim to steal sensitive information, such as credit card details or personal data, which they can then use or sell for financial profit.
NEW QUESTION # 116
During a cybersecurity investigation, a log entry states, "Unauthorized access attempt blocked from IP address 123.45.67.89." What can be inferred from this log entry?
- A. The system successfully prevented an unauthorized access attempt from a specific IP address.
- B. The system was compromised due to an unauthorized access attempt from IP address 123.45.67.89.

Option 2: Incorrect. While a firewall can scan and filter network traffic for potential threats, this is not its primary purpose.
Option 3: Incorrect. While encryption may be a feature of some firewalls, it is not the primary purpose of a firewall in a network security system.
Option 4: Incorrect. While a secure remote access solution may include a firewall, this is not the primary purpose of a firewall in a network security system.
NEW QUESTION # 118
Which of the following is a secure method for sharing sensitive documentation with external parties?
- A. Uploading the documents to a public file-sharing service
- B. Printing the documents and sending them through traditional mail
- C. Sending the documents via email attachments
- D. Using an encrypted communication channel
Answer: D
Explanation:
Sending sensitive documentation via email or public file-sharing services presents security risks. It is recommended to use an encrypted communication channel, such as secure file transfer protocol (SFTP) or a secure cloud-based collaboration platform, to protect the confidentiality and integrity of the information being shared.
NEW QUESTION # 119
Which of the following best defines the concept of preserving digital evidence?
- A. Gathering all digital evidence in a physical location.
- B. Destroying digital evidence after analysis to save storage space.
- C. Encrypting the digital evidence to prevent unauthorized access.
- D. Making an exact copy of the digital evidence for analysis.
Answer: D
Explanation:
Preserving digital evidence involves creating an exact copy of the original evidence to be used for analysis. This ensures that the original evidence remains intact and uncontaminated, while allowing investigators to work with a replicated version. It is crucial to prevent any modifications to the original evidence, as any changes can compromise the accuracy and integrity of the investigation.
