   A branch office has two routers (R1 and R2) providing default gateway redundancy for a /24 subnet. R1 is the preferred gateway because it has a higher-bandwidth uplink. You need to ensure that R1 is always the active forwarder when it is healthy, and that R2 takes over only if R1 fails. Which configuration approach meets this requirement?

   • AConfigure GLBP with load balancing across both routers.
   • BConfigure VRRP with priority 100 on both routers and enable preemption on R2 only.
   • CConfigure HSRP with priority 150 on R1, priority 100 on R2, and enable preemption on both.
   • DConfigure HSRP with equal priorities and rely on the default active router election.
