In which situations would you typically implement GLBP?

For static routing configurations
To prevent potential routing loops
For gateway redundancy and load balancing
When using OSPF exclusively

The correct answer is: For gateway redundancy and load balancing

Implementing Gateway Load Balancing Protocol (GLBP) is particularly advantageous in scenarios where there is a need for both gateway redundancy and load balancing among multiple routers. GLBP allows multiple routers to act as a single virtual gateway, distributing the traffic load between them while ensuring that if one of the routers fails, the others will continue to handle the traffic seamlessly. This capability enhances network reliability and performance, making it a preferred choice in environments where high availability and optimal resource utilization are critical. Other options do not accurately represent situations where GLBP would be implemented. Static routing configurations do not benefit from gateway redundancy as they typically involve a fixed routing path. While preventing routing loops is essential in networking, GLBP is not directly employed for this purpose; techniques like split horizon or route poisoning are more relevant for loop prevention. Lastly, using OSPF exclusively pertains to a different dynamic routing protocol, which does not necessitate the use of GLBP for redundancy or load balancing.
