Which two tasks must be performed before launching the Oracle universal installer to install Oracle Database Software for RAC? (Choose two.)
A.
SSH user equivalence for the Oracle software owner must be configured on all cluster nodes.
B.
Grid Infrastructure must be installed on all cluster nodes where the Database software will be installed.
C.
SSH user equivalence for the Oracle software owner must be configured on all cluster nodes where the Database Software will be installed.
D.
Grid infrastructure must be installed on all cluster nodes.
E.
The Clusterware stack must be up on all cluster nodes where the Database software will be installed.
F.
The Clusterware stack must be up on all cluster nodes.
Not A: Because the SCAN addresses resolve to the cluster, rather than to a node address in the cluster, nodes can be added to or removed from the cluster without affecting the SCAN address configuration.
Not B: EZConnect does not use tnsnames.ora
Yes C: If SCAN is used, connections are balanced across the three IP addresses defined for SCAN,…
Yes D: The SCAN listener redirects the connection request to the local listener of the instance that is least loaded…
Not E: the SCAN addresses resolve to the cluster…
C,D
Sorry, wrong question/answer. Please disregard.
ok, this is a tricky question, I am sure about C, the SSH connection but the other, I will base on the following
Install Oracle Grid Infrastructure for a cluster, which includes Oracle Clusterware and Oracle ASM (system and storage administration):
During installation, Fixup scripts perform additional configuration of operating system parameters, secure shell (SSH) for installation and user environment variables.
To configure Oracle RAC on an Oracle Flex Cluster, Oracle Grid Infrastructure for a cluster must be installed and configured in Oracle Flex Clusters mode.
Note:
You must have Oracle Grid Infrastructure installed successfully before you attempt to install Oracle RAC.

https://docs.oracle.com/database/121/RILIN/chklist.htm#RILIN969
so for me the correct answers are: B and C
BE
Agree, B and E
Digging and digging…
https://docs.oracle.com/database/121/RACAD/GUID-19E75965-E3B7-4ADE-9B31-FFEF50E5BE9C.htm#RACAD7278
If you choose the administrator-managed database deployment model, using a per-node installation of software, then it is sufficient to deploy the Oracle Database software (the database home) on only those nodes on which you plan to run Oracle Database.
If you choose the policy-managed deployment model, using a per-node installation of software, then you must deploy the software on all nodes in the cluster, because the dynamic allocation of servers to server pools, in principle, does not predict on which server a database instance can potentially run.
Oracle Universal Installer will only allow you to deploy an Oracle Database home across nodes in the cluster if you previously installed and configured Oracle Grid Infrastructure for the cluster.
so… what you HAVE to do at least? B and E but then you have to choose ADMINISTRATOR-MANAGED model of the cluster.
… however there on question 130 the only correct answers are
D.
Grid infrastructure must be installed on all cluster nodes.
E.
The Clusterware stack must be up on all cluster nodes.
so in this case we have to understand, that before installation started we do not decided what model of administration will be picked up hence correct answer here is
D F (GI installed and started on ALL nodes)
According to Documentation there is required:
6.1.2 Creating the Oracle Inventory Group -> B
6.1.3 Creating the Oracle Grid Infrastructure User -> C, however there has to be mistake in the text – not Oracle Database but Oracle GRID
hi Pawel, did you do the exam?
