Mohamed, I wanted to clarify the DNS Express question. DNS Express is not a feature of LTM...it either comes in BIG-IP GTM (or DNS SKUs) or it comes in the DNS Services add-on module to LTM. So it’s available on LTM either as GTM add-on, DNS Services add-on module, or it comes in a standalone GTM/DNS. I hope this clarifies for you. (and, thanks to Jonathan George for the awesome info on this answer!)
