Which three statements accurately describe update of software on Exadata Database Machine?

Which three statements accurately describe update of software on Exadata Database Machine?

A.
The Oracle Database patchset software (for example, 11.2.0.3) requires the Exadata-specific
version.

B.
Rolling patching is faster than non-rolling patching, but database down time is longer.

C.
The Oracle Database software on Exadata is updated using standard OPatch and the Oracle
Universal Installer.

D.
Running Exadata with different storage server software versions is supported, but should be
minimized to rolling patching scenarios.

E.
The database server operating system software (other than kernel and OFED) may be installed
or updated from non-Exadata sources

F.
Storage server updates require access to an Unbreakable Linux Network (ULN) based
repository.

Explanation:
C:
* Oracle offers two utilities for software deployment:
Oracle Universal Installer to install Oracle products
OPatch to apply interim patches
F: When storage cells are patched, there is almost always a set of storage server patches that
need to be applied to the Exadata Compute Nodes as well. Historically, these were called “minimal
packs,” but recent improvements to the compute node patching process deliver these updates
using yum channels on Oracle’s Unbreakable Linux Network (ULN).
Incorrect:
Not B: Rolling patching has no downtime.
