Final answer:
In a DNS tree, only the top-level domain nodes have primary names.
Step-by-step explanation:
In a DNS tree, each node represents a level in the hierarchy of domain names. However, not every node has a primary name. Only the top-level domain (TLD) nodes have primary names. These TLD nodes are the highest level in the DNS hierarchy and are responsible for managing domain names under their control. For example, the TLD node '.com' has the primary name 'com'.
Below the TLD nodes, there are second-level domain (SLD) nodes that are responsible for managing domain names under their respective TLD. These SLD nodes do not have primary names. For example, the SLD node 'example' under the TLD '.com' does not have a primary name.
Therefore, the statement (T/F)Each node in a DNS tree has a primary name is False.
