Answer:
Explanation:
Explanation:
A firewall is a set of related programs configured to protect private networks connected to the Internet from intrusion. It is used to regulate the network traffic between different computer networks. It permits or denies the transmission of a network packet to its destination based on a set of rules. A firewall is often installed on a separate computer so that an incoming packet does not get into the network directly.
NEW QUESTION # 167
Larry is responsible for the company's network consisting of 300 workstations and 25 servers. After using a hosted email service for a year, the company wants to control the email internally. Larry likes this idea because it will give him more control over the email. Larry wants to purchase a server for email but does not want the server to be on the internal network due to the potential to cause security risks. He decides to place the server outside of the company's internal firewall. There is another firewall connected directly to the Internet that will protect traffic from accessing the email server. The server will be placed between the two firewalls. What logical area is Larry putting the new email server into?
- A. He is going to place the server in a Demilitarized Zone (DMZ)
- B. For security reasons, Larry is going to place the email server in the company's Logical Buffer Zone (LBZ).
- C. Larry is going to put the email server in a hot-server zone.
- D. He will put the email server in an IPsec zone.
Answer: A
Explanation:
Larry is placing the new email server in a Demilitarized Zone (DMZ). A DMZ is a physical or logical subnetwork that contains and exposes an organization's external-facing services to an untrusted network, usually the internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external attacker only has access to equipment in the DMZ, rather than any other part of the network. The email server placed in the DMZ can be accessed from the internet, but it does not have direct access to the internal network, which reduces the risk of an internal security breach if the email server is compromised.
References: The concept of a DMZ is covered in the EC-Council's Certified Network Defender (C|ND) program, which teaches network administrators how to secure their networks against threats. The C|ND program includes strategies for protecting network infrastructure and creating secure architectures, which involves the use of DMZs123.
NEW QUESTION # 168
Emmanuel works as a Windows system administrator at an MNC. He uses PowerShell to enforce the script execution policy. He wants to allow the execution of the scripts that are signed by a trusted publisher. Which of the following script execution policy setting this?
- A. RemoteSigned
- B. AllSigned
- C. Restricted
- D. Unrestricted
Answer: B
Explanation:
The AllSigned execution policy in PowerShell requires that all scripts and configuration files be signed by a trusted publisher, including scripts that you write on the local computer. This setting is used when you want to ensure that only scripts that have been examined and signed by a trusted authority are run on your systems, which helps protect against the execution of unauthorized or malicious scripts. When using the AllSigned execution policy, PowerShell will prompt the user to confirm that they trust the signer before running any script.
References: This information aligns with the PowerShell documentation and best practices for script execution policies, which recommend the AllSigned policy for environments that require a high level of security12.
NEW QUESTION # 169

NEW QUESTION # 171
Brendan wants to implement a hardware based RAID system in his network. He is thinking of choosing a suitable RAM type for the architectural setup in the system. The type he is interested in provides access times of up to 20 ns. Which type of RAM will he select for his RAID system?
- A. NVRAM
- B. NAND flash memory
- C. SRAM
- D. SDRAM
Answer: C
Explanation:
SRAM, or Static Random-Access Memory, is known for its low access time, typically around 20 ns, which makes it suitable for applications requiring high speed, such as cache memory in computers or, in this case, a RAID system. SRAM is faster than DRAM because it does not need to be refreshed as often, which is why it's used where speed is critical. Although SRAM is more expensive and has less density compared to other types of RAM, its speed advantage makes it the preferred choice for Brendan's RAID system requirements.
References: The characteristics of SRAM are well-documented in computer architecture and hardware literature, aligning with the Certified Network Defender (CND) course's focus on understanding different types of memory for network security purposes. The ECCouncil's CND materials and study guides provide information on various hardware components and their relevance to network security, which includes the selection of appropriate RAM types for different systems123.

NEW QUESTION # 174
A network is setup using an IP address range of 0.0.0.0 to 127.255.255.255. The network has a default subnet mask of 255.0.0.0. What IP address class is the network range a part of?
- A. Class C
- B. Class B
- C. Class D
- D. Class A
Answer: D
Explanation:
The IP address range from 0.0.0.0 to 127.255.255.255 falls under Class A. In the Class A type of network, the first octet (the first 8 bits of the IP address) is used for the network part, and the remaining 24 bits are used for host addresses. The default subnet mask for Class A is 255.0.0.0, which aligns with the given network's default subnet mask. Class A networks are designed to support a very large number of hosts. The first bit of a Class A address is always set to 0, which means the first octet can range from 1 to 127, thus including the given IP address range.
References: This explanation is based on standard networking principles regarding IP address classes as outlined in resources like the Meridian Outpost article on IPv4 address classes1, and is consistent with the objectives and documents of the EC-Council's Certified Network Defender (CND) program.

NEW QUESTION # 176
Blake is working on the company's updated disaster and business continuity plan. The last section of the plan covers computer and data incidence response. Blake is outlining the level of severity for each type of incident in the plan. Unsuccessful scans and probes are at what severity level?
- A. High severity level
- B. Extreme severity level
- C. Mid severity level
- D. Low severity level
Answer: D
Explanation:
In the context of incident response, unsuccessful scans and probes are typically considered a low severity level. This is because they often indicate an attempted reconnaissance or mapping of systems rather than a successful compromise or disruption of services. While they should be monitored and analyzed to improve defenses and detect patterns of malicious activity, they do not usually signify an immediate threat to the integrity, availability, or confidentiality of systems.
References: The classification of unsuccessful scans and probes as low severity is consistent with standard practices in incident response and is supported by various cybersecurity frameworks and guidelines, including those from the EC-Council's Certified Network Defender (CND) program.
NEW QUESTION # 177
Which among the following options represents professional hackers with an aim of attacking systems for profit?
- A. Cyber terrorists
- B. Script kiddies
- C. Hacktivists
- D. Organized hackers
Answer: D
Explanation:
Organized hackers are professional cybercriminals who often work in groups and are motivated by financial gain. They are known for their skills and the ability to carry out sophisticated attacks on systems for profit. Unlike script kiddies, who lack advanced skills and typically use readily available tools, organized hackers use custom-developed tools and methods. Hacktivists are motivated by political or social causes, and cyber terrorists aim to use cyber attacks to create fear or political change, not necessarily for profit.
NEW QUESTION # 178
CORRECT TEXT
Fill in the blank with the appropriate term. ______________is a method for monitoring the e-mail delivery to the intended recipient.
Answer:
Explanation:
Email tracking
Explanation:
Email tracking is a method for monitoring the e-mail delivery to the intended recipient. Most tracking technologies utilize some form of digitally time-stamped record to reveal the exact time and date at which e-mail was received or opened, as well the IP address of the recipient. When a user uses such tools to send an e-mail, forward an e-mail, reply to an e-mail, or modify an e-mail, the resulting actions and tracks of the original e-mail are logged. The sender is notified of all actions performed on the tracked e-mail by an automatically generated e-mail. eMailTracker Pro and MailTracking.com are the tools that can be used to perform email tracking.
NEW QUESTION # 179
Which of the following is a protocol that describes an approach to providing "streamlined" support of OSI application services on top of TCP/IP-based networks for some constrained environments?
- A. Dynamic Host Configuration Protocol
- B. Internet Relay Chat Protocol
- C. Network News Transfer Protocol
- D. Lightweight Presentation Protocol
Answer: D
Explanation:
Lightweight Presentation Protocol (LPP) is a protocol that describes an approach to providing "streamlined" support of OSI application services on top of TCP/IP-based networks for some constrained environments. This protocol was initially derived from a requirement to run the ISO Common Management Information Protocol (CMIP) in TCP/IP-based networks. This protocol is designed for a particular class of OSI applications, namely those entities whose application context includes only an Association Control Service Element (ACSE) and a Remote Operations Service Element (ROSE). Answer option D is incorrect. The Dynamic Host Configuration Protocol (DHCP) is a computer networking protocol used by hosts (DHCP clients) to retrieve IP address assignments and other configuration information. DHCP uses a client-server architecture. The client sends a broadcast request for configuration information. The DHCP server receives the request and responds with configuration information from its configuration database. In the absence of DHCP, all hosts on a network must be manually configured individually - a time-consuming and often error-prone undertaking. DHCP is popular with ISP's because it allows a host to obtain a temporary IP address. Answer option A is incorrect. Answer option C is incorrect. Internet Relay Chat (IRC) is a chat service, which is a client-server protocol that supports real-time text chat between two or more users over a TCPIP network.
NEW QUESTION # 180
Hacktivists are threat actors, who can be described as -------------------
- A. Disgruntled/terminated employees
- B. People motivated by religious beliefs
- C. People motivated by monetary gams
- D. People having political or social agenda
Answer: D
Explanation:
Hacktivists are individuals or groups that use computer networks and hacking techniques to promote a political or social agenda. Unlike other threat actors who may be motivated by financial gain or personal beliefs, hacktivists typically aim to draw attention to social, environmental, or political issues. They often engage in activities such as website defacement, denial-of-service attacks, or the release of confidential information to make a statement or force change related to their cause.
References: The EC-Council's Certified Network Defender (CND) program discusses various types of threat actors, including hacktivists, as part of its curriculum on network security and defense strategies1. The program emphasizes the importance of understanding the motivations behind different threat actors to effectively protect, detect, respond, and predict network security incidents1.
