You need to decide on the best router redundancy protocol to use in the Company network.
 Which  two statements are true about HSRP, VRRP, and GLBP?()

A. GLBP and VRRP allow for MD5 authentication, whereas HSRP does not.
B. HSRP allows for multiple upstream active links being simultaneously used, whereas GLBP  does not.
C. GLBP allows for router load balancing of traffic from a network segment without the different  host IP configurations required to achieve the same results with HSRP.
D. Unlike HSRP and VRRP, GLBP allows automatic selection and simultaneous use of multiple  available gateways.
E. GLBP allows for router load balancing of traffic from a network segment by utilizing the creation  of multiple standby groups.

 Which two statements are true about the Hot Standby Router Protocol (HSRP)? ()


A. Load sharing with HSRP is achieved by creating multiple subinterfaces on the HSRP routers.  
B. Routers configured for HSRP can belong to multiple groups and multiple VLANs.
C. Load sharing with HSRP is achieved by creating HSRP groups on the HSRP routers.
D. All routers configured for HSRP load balancing must be configured with the same priority.  
E. Routers configured for HSRP must belong to only one group per HSRP interface.
