Well, MTA IT infrastructure is just the category - there are 4 certs under it. Network, security, server, and Windows OS.
I suppose that preparing for IC3 and Strata would help with the MTA, but you'll definitely need to know more. The MTAs are pretty basic, but something like the IC3 is just plain old computer literacy, like knowing the difference between RAM and ROM. The MTAs are going to be a cut above that.
If you're starting off at almost zero knowledge then IC3/Strata -> MTA -> A+/Net+ -> MCSA/vendor-specific-cert would be a good path. I personally think that any certs below A+ are worthless (A+ isn't all that, either), but you do want to have the knowledge and skills that those exams are supposed gauge.
