A customer requests a design that includes GLBP as the FHRP. The network architect discovers that the members of the GLBP group have different throughput capabilities. Which GLBP load balancing method

Question

Options

• Ahost dependent
• Bleast connection
• Cround robin
• Dweighted

• A
  17% (7)
• B
  2% (1)
• C
  7% (3)
• D
  74% (31)

Explanation

Weighted load balancing is the correct GLBP method because it allows each Active Virtual Forwarder (AVF) to be assigned a weight value (1–254) proportional to its throughput capability, meaning more powerful routers receive a greater share of traffic. Host dependent (Option A) is incorrect because it ensures a specific host always uses the same gateway MAC address for consistency, not to account for differing device capabilities. Round robin (Option C) is incorrect because it distributes traffic equally across all AVFs regardless of their individual capacity, which would overburden less capable devices. Least connection (Option B) is a load balancing method used in server load balancers and application delivery controllers - it is not a valid GLBP load balancing option at all.

Memory Tip: Think of "weighted" like a weightlifting team - stronger members (higher-capacity routers) carry more weight (more traffic). If devices have unequal strength, you need a weighted approach to fairly distribute the load.
