You could build a lab, using vSANs you could make a moderately complex typology. Have a 3 sites, each being a datacenter in vCenter. Each could have it's own vSAN. 2 AD servers,a SQL server, file/print. Setup DFS replication, AD sites and services, Storage vMotion, vMotion, HA. Setup DR recovery option with replication. You could mix in a few Linux Web Servers that authenticate against AD and is load-balanced using virtual appliance.
Then there's the security setup using an IDS to sniff traffic off the vNetwork. On the client side you could setup SMS (or whatever Microsoft calls it now) and push out software. Also use RIS to push out client images to VM. Lockdown clients via GPO.
That covers virtualization, Windows, some Linux, some security, DR. Then document everything and write up DR procedures, it could be a useful reference typology if done well.
But that doesn't include any coding seems like something a infrastructure architect might do though.
