Refer to exhibits 1 and 2. In exhibit 1， all users on the LAN segment use router A as the active HSRP router. Router B is the standby router for the HSRP. In exhibit 2， the network management team reported that there is no utilization on the WAN link B. To solve this problem， you decide to change the logical topology of your LAN， but you are not sure about what changes must be made. You must manage HSRP or change it to another protocol in order to provide the most scalable design， automatic redundancy， and load balancing. Which one of these actions would be the best choice？ （）
- A Use MHSRP， with three users using router A as the default gateway and three users using router B as the default gateway.
- B Keep HSRP and activate PBR to redirect half of the traffic to the other WAN link.
- C Use the backup interface on the WAN link B to provide load balancing for all users.
- D Use GLBP instead， because it provides you with up to three MAC addresses for the same default gateway virtual IP address.
- E Use GLBP instead， because it provides you with up to four MAC addresses for the same default gateway virtual IP address.
