Scenario: A Citrix Administrator executed the command below in an active-active, global server load balancing (GSLB) setup. set gslb parameter -ldnsprobeOrder DNS PING TCP
The order to calculate the _____ for dynamic proximity will be the DNS UDP query followed by the ping and then TCP. (Choose the correct option to complete the sentence.)
The correct answer is Round-trip time (RTT). The order of DNS UDP query, followed by ping, and then TCP in the given command is used to calculate the round-trip time, which is a measure of the total time it takes for a data packet to travel from the source to the destination and back. This helps in determining the proximity of different sites for global server load balancing.
