Spanning Tree Protocol IEEE 802.1s defines the ability to deploy which of these?
The correct answer is C. one STP instance per set of VLANs. The IEEE 802.1s standard is the Multiple Spanning Tree (MST). With MST, you can group VLANs and run one instance of Spanning Tree for a group of VLANs. Other STP types: Common Spanning Tree (CST), which is defined with IEEE 802.1Q, defines one spanning tree instance for all…

Explanation
The IEEE 802.1s standard is the Multiple Spanning Tree (MST). With MST, you can group VLANs and run one instance of Spanning Tree for a group of VLANs. Other STP types: Common Spanning Tree (CST), which is defined with IEEE 802.1Q, defines one spanning tree instance for all VLANs. Rapid Spanning Tree (RSTP), which is defined with 802.1w, is used to speed up STP convergence. Switch ports exchange an explicit handshake when they transition to forwarding.
