Best way of connecting multiple sites together?

What would be the best way of connecting multiple sites together? I know this has many contributing factors.. But generally

So far I'm with leased line using T3/4/5.. But what other methods can I use?

L2L VPN (Hub and Spoke, no spoke to spoke traffic)
MPLS
DMVPN
IWAN

I'd look to go with IWAN since it's more developed now : )

You're a CCNA Security, you should already have ideas, i'd at least expect you to have posted some.

I had some other ideas but I wasn't certain since my score for CCNA Sec was borderline pass and uni wanted me to dive away from Cisco related topics since it's all I've done for the entirety of the network-related modules

Depends on the platforms available for you to use and business requirements.
For example, you could use OTV with Nexus if you need layer 2 connectivity.

What services and functions do you need to do?

Voip, video, data, storage, speciality? This along with ipsec reqs will drive network design. Is there a core site?

Exactly as philz192 said. What are the requirements? That's how you find the best way to do it.

Too many times I see people trying to fit requirements into a network design they got out of a book rather than designing a network around the requirements in the first place.

This is a real shot in the dark and way above my knowledge level, but would a Layer 2 MPLS/VLAN designed network not be a solution for connecting the sites and supporting services like the above between them?

Like I said, its a real uneducated guess build on what I know from hearing Net Engineers building L2 MPLS circuits.

It depends then what his core architecture is and if he has a central site. Plus the MPLS Circuits have nothing to do with the business outcomes. Not being critical, just none of us have enough until the OP clarifies.

He really needs to lay out the functions of his network. No one can give him a design until he tells us what he intends to do. This could be something as simple as a few ISR's head-ending back to a Cisco Router. Of, course what if he is an HP shop, or avaya, or Brocade. Just way to many unknowns....
