Which two network design features require Spanning Tree Protocol (STP) to ensure correct network operation? (Choose two.)
- static default routes
- implementing VLANs to contain broadcasts
- redundant links between Layer 2 switches
- link-state dynamic routing that provides redundant routes
- removing single points of failure with multiple Layer 2 switches
Answers Explanation & Hints: Spanning Tree Protocol (STP) is required to ensure correct network operation when designing a network with multiple interconnected Layer 2 switches or using redundant links to eliminate single points of failure between Layer 2 switches. Routing is a Layer 3 function and does not relate to STP. VLANs do reduce the number of broadcast domains but relate to Layer 3 subnets, not STP.
