312-38 Exam Dumps : Certified Network Defender (CND)

A CCTV camera that can be accessed on a smartphone from a remote location typically uses the Device-to-Cloud communication model. This model involves devices that connect directly to the cloud where data is stored and processed. Users can access this data through an application on their smartphones, allowing for remote monitoring and control. This setup is common for IP cameras that transmit data over the internet, enabling users to view live footage or recordings from anywhere with an internet connection123.

References: The Device-to-Cloud communication model is widely recognized in the context of remote access to surveillance systems, as it provides the necessary infrastructure for transmitting and storing data from CCTV cameras to a cloud platform, which users can then access via smartphones or other devices123.

 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.

A hot backup, also known as an online backup or dynamic backup, is the process of backing up data while the system continues to be in operation. This means that there is no need for system downtime or interruption in services while the backup is taking place. It is mostly used in systems where operations are critical and cannot afford any downtime, such as databases and servers that must be available 24/7. The hot backup method allows for data to be backed up at regular intervals with minimal impact on the system’s performance, ensuring that the organization can maintain continuous service levels.

References: The concept of hot backup is aligned with the ECCouncil’s Network Defender (CND) objectives and is supported by industry best practices as detailed in sources like MiniTool1 and NinjaOne2, which discuss the advantages of hot backups in maintaining uninterrupted service and business continuity.
