Which dynamic load balancing mode affects loadbalancing decisions based on path metrics?

Packet Rate is a dynamic mode that bases decisions on the number of packets per second handled by a virtual server, which reflects server load rather than path metrics.

Completion Rate measures the ratio of successful DNS query completions to total queries sent toward each virtual server, effectively reflecting path quality and reliability metrics. Because it evaluates actual packet delivery success over the network path, it is classified as a path-metric-based dynamic load balancing mode. GTM uses this ratio to prefer virtual servers reachable over higher-quality paths.

Least Connections is a load balancing mode that directs traffic to the virtual server with the fewest active connections, focusing on server-side load rather than network path quality.

Virtual Server Capacity is a dynamic mode that evaluates the available resource capacity on the virtual server itself, not the quality or performance of the network path.
