Explanation

GLBP (Gateway Load Balancing Protocol) is a Cisco proprietary protocol with these key characteristics: (B) It supports both clear text and MD5 password authentication between GLBP group members for security. (D) GLBP supports up to 1024 virtual router groups (0–1023), giving it broad scalability. (E) GLBP load shares traffic across a maximum of four routers simultaneously, which is its key differentiator from HSRP and VRRP. Choice A is wrong because GLBP supports up to 4 virtual forwarders per group, not 8. Choice C is wrong because GLBP is Cisco proprietary, not an open standard. Choice F is wrong because GLBP elects only one AVG (Active Virtual Gateway) and one standby AVG, not two of each.
