I am using Vegas Pro 14 build 211. At the moment I am rendering mpeg-2 video and AC3 audio separately. Can I render them together. Sending to DVD Architect is the only way I can play these files together.

Why? - And yes, this is when you want to produce a DVD. And yes, we sure can "Rendering Video and audio together" So, what is it you want to end up with?
If you just want to produce a file that plays on a large number of devices use the Mainconcept AVC/AAC Internet template that closely matches your source pixel dimensions and frame rate.
If you're producing separate elementary streams so you can produce DVDs or Blu-ray discs, all is not lost. You can use a program like tsMuxer to wrap the separate video and audio files into a .ts or .m2ts wrapper.
Typically, the audio file type for DVD and BluRay is AC-3 or PCM (.wav). For the web and other streaming scenarios.. AAC. If that's rendered separately from the video it usually has the <.mp4> or <.m4a> extension. FWIW, I use MeGUI to mux in AAC audio to a AVC video
