A typical scenario is when there are threats from outside the school, like Death Eaters. Draco, having insider knowledge of their plans, decides to protect Harry. He might lie to the Death Eaters about Harry's whereabouts or physically stand in their way to buy Harry time to escape.
One common scenario is in a dangerous magical situation. For example, in a battle at Hogwarts, Draco might step in to protect Harry from a dark wizard's spell. Another could be in the face of social threats within the school. Maybe some students are trying to bully Harry, and Draco, having a change of heart, defends him. It could also be that Draco protects Harry from a plot within the Slytherin house that aims to harm Harry due to his fame as 'The Boy Who Lived'.
Often, in the 'Draco protects Harry' fanfictions, a scenario could be during a dangerous potion - making experiment gone wrong. Draco, using his knowledge of potions, saves Harry from the harmful effects. Also, there might be a situation where they are exploring a hidden part of the castle together, and Draco shields Harry from a hidden magical trap.
