Inserting a single key value into a B-tree can result in more than one node splitting operation.

Question

Quizplus · Accepted Answer

When inserting a key value in a B-tree, if the node into which the key is to be inserted is already full, then a splitting operation is required. This may result in the splitting of multiple nodes, as the newly added key may cause nodes higher up the tree to also become full and require splitting. Therefore, inserting a single key value into a B-tree can result in more than one node splitting operation.
