Question 1100
At Lakeside Classroom, a topology change moves the root toward a low-bandwidth edge switch. What should the engineer implement first to correct the stated condition?
Explanation
Correct Answer
For Lakeside Classroom, the decisive mechanism is RSTP root placement. RSTP uses a root bridge and port roles to build a loop-free Layer 2 topology. Set the appropriate spanning-tree priority to retain an intentional distribution root establishes the needed configuration in the case rather than merely measuring a symptom.
Incorrect Answers
This is relevant to VSX keepalive separation, where the VSX keepalive helps distinguish peer failure from ISL failure In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology
This is relevant to VSX inter-switch link, where vSX peers synchronize selected state over an ISL while retaining independent control planes In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology
This is relevant to VSX active gateway, where vSX active gateway allows distributed L3 gateway forwarding when configured consistently In the Lakeside Classroom case, Changing that neighboring feature does not implement the missing function. The specific mechanism is rSTP uses a root bridge and port roles to build a loop-free Layer 2 topology
