HOTSPOT
You have a SharePoint Server 2013 server farm.
You plan to create three web applications that must meet the requirements described in the
following table.
In the table below, identify which type of site collection must be used for each web application.
Make only one selection in each row.
Answer: 
Explanation:
Note:
* Host-named site collection
Host-named site collections are the preferred method to deploy sites in SharePoint 2013. Because
the Office 365 environment uses host-named site collections, new features are optimized for these
site collections and they are expected to be more reliable.
* Path-named site collection
Use path-named collections when you need to use alternate access mappings (AAMs).
Host-named site collections can only be created via PowerShell, so the first row must be path-based
Agreed – I think all of these are Path based as self service site creation wouldn’t be HNSC?
All path based site collection

Alternate Access mapping only supported with Path based, Host named uses PowerShell.
and the same with self service.
