How does DNS caching handle fixed order records

If my BigIP LTM DNS Cache receieves a response from the DNS pool with three A records, and caches it, would all subsequent queries recieve the same response ie in the same order

 

DNS response recieved and cached:

 

www.example.com 10.10.10.10 10.10.10.20 10.10.10.30

 

Will later consecutive responses answered from the cache be:

 

www.example.com 10.10.10.10 10.10.10.20 10.10.10.30

 

www.example.com 10.10.10.10 10.10.10.20 10.10.10.30

 

www.example.com 10.10.10.10 10.10.10.20 10.10.10.30

 

Or will the cache do some kind of random/round-robin technique, eg

 

www.example.com 10.10.10.10 10.10.10.20 10.10.10.30

 

www.example.com 10.10.10.20 10.10.10.30 10.10.10.10

 

www.example.com 10.10.10.30 10.10.10.20 10.10.10.10

 

Thanks for your help

 

Bob
