Recreating a Node Status Dependent Round Robbin DNS effect with F5

I was told by a consultant that, out setup being in an active-passive pair (we have a pair of synchronized F5 boxes), implementing GTM to do DNS load balancing like the one we would like to implement here is not a good idea. Is it true? For what reason? In the case it would be true, are there workarounds? What are the pros? The cons?

 

Thanks

Typically GTMs are deployed in an active-active scenario. I've never attempted or heard of a scenario where someone deployed GTMs in active-standby. I suspect it could be problematic just based on the way DNS delegation would work from a parent zone, though I can't say definitively. I'll have to defer to someone else who has attempted a GTM active-standby config.
