You are delivering a replacement collapsed core network proposal to the customer where the core switches will have the switched virtual interfaces (SVI) configured. The customer is not sure that a VSX pair of switches will be able to act as the spanning tree root in their environment. Which options are true about spanning tree and VSX that will help assure the customer that a VSX pair of switches are appropriate for a collapsed core? (Choose two.)

1. A. The ISL between VSX switches is never part of STP domain and doesn't send or receive BPDUs on this link and this ensures the "operational primary" and "operational secondary" switches are deterministic to other dual-attached switches. — đáp án hiện tại
2. B. Both VSX switches are configured with the system MAC and then create unique STP bridge-IDs to identify "operational primary" and "operational secondary" for proper STP functioning.
3. C. HPE Aruba Networking VSX switches support either multiple spanning tree (MSTP) or rapid per VLAN spanning tree (RPVST). — đáp án hiện tại
4. D. When LAG interfaces are configured on a VSX pair of switches, both switches are "operational primary" and ensure active-active LAG operation equally.
5. E. The primary VSX switch is the spanning tree root and the default behavior is the links on the secondary VSX switch are blocked with sub-millisecond failover assured by VSX active-gateway.
