A network administrator has designed a network with two multilayer switches on the distribution layer, which act as default gateways for the end hosts. Which two technologies allow every end host in a VLAN to use both gateways? (Choose two)
Correct Answer: A,C
GLBP (Gateway Load Balancing Protocol) and MHSRP (Multigroup Hot Standby Router Protocol) are the two technologies that enable all end hosts in a VLAN to utilize both gateways. GLBP allows for automatic load balancing on a single IP address, distributing client requests among all available routers. It achieves this by assigning multiple virtual MAC addresses to a single virtual IP address, which the end hosts use as their default gateway. MHSRP, on the other hand, is a variation of HSRP that allows for the creation of multiple HSRP groups on a single interface, providing load balancing by assigning different groups to different end hosts.
