Prioritizing incidents in a network environment, especially within a critical infrastructure like a bank, should be based on the potential technical effect of the incident. This approach ensures that the most severe and impactful issues are addressed first to maintain business continuity and minimize potential damage. The incident involving the main server would likely take precedence because it could affect a larger number of systems and operations within the bank, compared to an individual’s login issue. The ITIL framework supports this prioritization method by emphasizing the importance of impact and urgency when managing network incidents12. References: The prioritization strategy aligns with best practices outlined in the ITILframework for IT service management, which suggests managing incidents based on their severity, urgency, and impact on business operations12.QUESTION NO: 47

Nancy is working as a network administrator for a small company. Management wants to implement a RAID storage for their organization. They want to use the appropriate RAID level for their backup plan that will satisfy

the following requirements: 1. It has a parity check to store all the information about the data in multiple drives 2. Help reconstruct the data during downtime. 3. Process the data at a good speed. 4. Should not be

expensive. The management team asks Nancy to research and suggest the appropriate RAID level that best suits their requirements. What RAID level will she suggest?

A. RAID 0

B. RAID 10

C. RAID 3

D. RAID 1

Answer: C

RAID 3 is a level of RAID that uses striping with a dedicated parity disk. This means that data is spread across multiple disks, and parity information is stored on one dedicated disk. RAID 3 allows for good read and write speeds and can reconstruct data if one drive fails, thanks to the parity information. It is also a cost-effective solution because it requires only one additional disk for parity, regardless of the size of the array. This makes it suitable for environments where data throughput and fault tolerance are important but budget constraints are a consideration.

References: The explanation aligns with the RAID level characteristics and the requirements specified by the management team. RAID 3’s ability to provide parity checks, data reconstruction during downtime, and process data at a good speed while being cost-effective makes it an appropriate choice123.

 In Debian-based Linux distributions, such as Ubuntu, the update-rc.d command is used to add and remove services from the startup sequence. To disable a service, the -f option (which stands for ‘force’) is used along with the remove parameter to remove the service from the startup sequence. This prevents the service from starting automatically during the system boot.

References: The use of update-rc.d for disabling services is documented in various Linux guides and resources. For example, Tecmint’s guide on “How to Stop and Disable Unwanted Services from Linux System” provides a practical example of using update-rc.d -f apache2 remove to disable the Apache service at system startup1. Additionally, the Linux Consultant website also mentions the use of systemctl followed by the disable argument for fully disabling services2.

 Adware is a type of software designed to throw advertisements up on your screen, most often within a web browser. This typically happens when a user installs a free application or software that includes adware in its installation package. In Riya’s case, the sudden influx of advertisements for clothes and watches similar to her recent purchases suggests that adware might have been installed on her device. This adware is likely tracking her browsing habits and displaying targeted ads based on her online shopping activity.

References: The explanation aligns with the objectives and documents of the Certified Network Defender (CND) course, which covers various types of malware, including adware, and their characteristics. For more detailed information, refer to the CND study guide and materials provided by the EC-Council on malware and its impact on network security.

 Network Interface Cards (NICs) operate at the Physical layer of the OSI model. This layer is responsible for the actual physical connection between devices. It transmits individual bits from one node to the next and is involved in the electrical, mechanical, procedural, and functional aspects of activating, maintaining, and deactivating physical connections. It’s also where hardware like cables, switches, and NICs come into play.

References: The information provided aligns with the OSI model’s definition and the role of the Physical layer as described in networking literature and resources such as GeeksforGeeks and freeCodeCamp articles on the OSI model12.
