unmanaged switch connect to 2 cisco 2960's that are trunked together

Hopefully everyone understands this. say I have 2- 2960's that are connected to each other with a trunk, for DR purposes. Now someone wants to connect a unmanaged smaller switch and plug it into both 2960's to provide network access to both 2960's in case one of them fails. wouldn't that create a loop no matter what is done or would STP handle the situation?

That's correct, you will

That's correct, you will create a loop.  


Ideally, STP would've handled the situation but there are known cases when un-managed switches do not play "fair" or they just don't follow the rules.  And this happens.  


Nowadays, if you know what you are going to do, this is why stacked switches  are ideal for scenarios like this.
