Câu 39: HP0-Y50: Architecting HP FlexNetwork Solutions

Refer to the exhibits. Exhibit 1 - Exhibit 2 - A customer has a existing solution, which is shown in Exhibit 1. (The solution actually includes more access layer switches than shown) in the existing solution, each access layer switch routes traffic. A network architect is proposing the HP FlexCampus solution shown in exhibit 2 in this proposed solution, the core intelligent Resilient Framework (IRF) virtual switch routes traffic, but the access layer switches do not. The customer likes that in the existing solution STP does not block either access layer uplink. The customer also likes that the existing solution does not requireVirtual Router Redundancy Protocol (VRRP). What should the architect tell the customer about the benefits of the proposed solution?

1. A. Although the IRF core must implement VRRP, STP does not block either access layer uplink, letting failover occur more quickly
2. B. STP does not block either access layer uplink, and routing redundancy is provided without VRRP
3. C. Although the IRF core must implement VRRP, VRRP is easier to set up than a dynamic routing protocol on all the switches
4. D. STP will block one uplink on each access layer switch, but IRF enables failover to occur much more quickly — đáp án hiện tại
