What are three ways that auto deploy can access the answer file?

An administrator is using vSphere auto deploy to Deploy 25 ESXi hosts. The information used for deployment will be stored using an answer file.
What are three ways that auto deploy can access the answer file? (Choose Three) (PLEASE REVIEW)

A.
ISO

B.
CIFS

C.
SFTP

D.
HTTP

E.
NFS

Explanation:
Prior it was 3 choices – then one – then none because of the following answers…
I think this question is incomplete and personally think it was talking about answer files alone. Just note all the autodeploy doc’s don’t say.

The only protocol they mention is HTTP. Also, since the AD server is Linux based that would only mean SFTP and NFS would work or could work if it is 3 options. HTTP would be correct if it was one answer… Corrrect answer should be none… I don’t think this is correct because of the following excerpt:
The answer file is not stored in a location or format that administrators can access. Use the Host Profiles UI in the vSphere Client to manage answer files. The correct answer is D. HTTP. See the VMware AutoDeploy Administrator’s guide, page 9

The administrator does not need to access the files, the question is about auto deploy process downloading the configuration file. The document doesn’t mention other ways but HTTP. The question might be wrong on VCP test, this way nobody could score 500. But if I have to choose 3 answers, I would go with C. SFTP, D. HTTP and E. NFS. Vsphereking, thank you very much for the hard work, I’m taking VCP test next week. THIS ONE is kind of interesting… from what I have been reading… Answer files are stored differently when using Auto Deploy… From what I gather below and from the admin guide itself AutoDeploy Completely stores and gives management of the answer files to vCenter. It is not accessible to admins…..

Pay close attention as well… Previously Kickstart installs and upgrade/Install scripts could be stored on these types of storage-access protocols but Auto Deploy is Completely Different! All these answers to this question are wrong IMO as the correct answer should be a new one – vsphere-esxi-vcenter-server-50-auto-deploy-guide
The installation or upgrade script can reside in one of the following locations (normal upgrade):

o FTP

o The following locations are supported for the installation or upgrade script:
o CD/DVD.
o USB Flash drive
o A location accessible with the following protocols: NFS, HTTP, HTTPS, FTP When using AutoDeploy:
The answer file is not stored in a location or format that administrators can access. Use the Host Profiles UI in the vSphere Client to manage answer files.
