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

When a Trojan is suspected to have infected a computer, the first course of action should be to contain the damage to prevent the malware from spreading or causing further harm. This involves disconnecting the infected device from the network to isolate it and prevent the Trojan from communicating with potential command and control servers or infecting other systems123.

While informing the Incident Response Team (IRT) and other members of the organization is also important, these actions come after the immediate threat has been contained. Therefore, the correct answer is to contain the damage (A), which aligns with the Certified Network Defender (CND) objectives that prioritize immediate containment to minimize the impact of security incidents45678.

References: The response is based on best practices for dealing with Trojans as outlined in network security and incident response guidelines, including those from the EC-Council’s Certified Network Defender (CND) program. The CND framework emphasizes the importance of quick containment to protect network integrity and prevent further damage45678.

In a tree network, each node is connected in a hierarchical manner, with the root node at the top. If a main node (such as N1 or N2) fails, all the child nodes connected to it (N11, N12 for N1 and N21, N22 for N2) will be affected because the tree structure relies on the connectivity of the parent node to its children. The failure of a main node will disrupt the transmission path from the root to the child nodes, leading to a loss of connectivity for those child nodes. This is consistent with the principles of network resilience and fault tolerance as outlined in the EC-Council’s Certified Network Defender (CND) program, which emphasizes the importance of each node in maintaining the network’s overall integrity.

References: The explanation is based on the standard network topologies and fault tolerance principles covered in the EC-Council’s Certified Network Defender (CND) curriculum.

Purging is a data destruction technique designed to protect the sensitivity of information against laboratory attacks. In such attacks, unauthorized individuals may use advanced signal processing recovery tools to recover previously stored information. Purging involves removing the stored data in a way that it cannot be reconstructed by any means, including laboratory techniques. This process often includes degaussing, which demagnetizes the magnetic field of storage media, thereby making data recovery virtually impossible.
