As a GM in a game I would not have the players even deal with the guards if it is a forgone conclusion.
Players in my experience are only concerned with encounters that are a challenge and give them XP.
If you have them roll against these guards that are so far below them that the challenge level gives no xp they are going to start wondering why you are even bothering.
While the guards are still there, in a sense they have cease to be an issues, so in most games no roll is needed, hence they vanishes altogether.
In a typical fighter-wizard-rogue-cleric party, it gets hard to tell what will be a foregone conclusion since everybody’s great at their own stuff but sucks at everyone else’s stuff. The DM knows what’s going to need a roll and what he can skip rolling out when the players have decided what they will do, not before.
And similar effects occur even with high-level NPCs, since they can’t all be renaissance men and women who are good at everything. If the PCs find a way of dealing with them using their own strengths versus the NPC’s weakness, they’ll have it easy - because mechanically, they’ll have a high bonus compared to the NPC’s. At low levels everyone has a low bonus, even if some are lower than others.
If the “strong” PC has a +5 bonus for the relevant skill and the “weak” one has a +2, that d20 roll is going to be very swingy if the idea is that they both should be able to do something with that skill. If one has a +17 and the other a +5 on the other hand, the die roll probably isn’t going to matter for one of them.
