Consider a scenario consisting of a tree network. The root Node N is connected to two man nodes N1 and N2. N1 is connected to N11 and N12. N2 is connected to N21 and N22. What will happen if any one of the main
nodes fail?
A.
Failure of the main node affects all other child nodes at the same level irrespective of the main node.
B.
Does not cause any disturbance to the child nodes or its tranmission
C.
Failure of the main node will affect all related child nodes connected to the main node
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.
