Which two characteristics are associated with 802.

C (Faster convergence): 802.1s (Multiple Spanning Tree Protocol – MSTP) improves convergence times over legacy 802.1D (STP) and PVST+ by leveraging the rapid convergence benefits of 802.1w (RSTP).

E (Maps multiple VLANs): MST allows multiple VLANs to share the same spanning-tree instance, reducing the overall number of instances required and improving scalability.

Other options explained:

A: The standard supports 64 MST instances, not 1024.

B: 802.1w (RSTP) is the basis for 802.1s; Cisco’s proprietary enhancement was originally PVST+.

D: MST actually reduces CPU/memory compared to running multiple instances of PVST+.
