HDPCA exam objectives: "Add a new node to an existing cluster"

[#1]

I am preparing for HDPCA exam and going through the list of exam objectives and have a few questions:

1) When I click on "Add a new node to an existing cluster" it refers to http://docs.hortonworks.com/HDPDocuments/Ambari-2.0.0.0/Ambari_Doc_Suite/ADS_v200.html#ref-d745870f-.... Is this reference correct? I believe It should refer somewhere here: http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_Sys_Admin_Guides/content/ref-4303e343-9ae...

2) It is not clear if "Manually Adding Slave Nodes to an HDP Cluster" is part of HDPCA exam or it will be enough just to be acquainted with adding nodes with Ambari.

Thank you,

Yes, reference link is correct one...

http://docs.hortonworks.com/HDPDocuments/Ambari-2.0.0.0/Ambari_Doc_Suite/ADS_v200.html#ref-d745870f-...

either way (ambari url/Manual) you can add new node to exiting cluster...best option/easy way use Ambari url...

Refer using Ambari url :
