Levels of Knowledge
Each exam topic contains objectives and each objective is categorized by learner or practitioner level of knowledge.
Learner items test foundational grasp and
require product comprehension (not
recognition or memorization).
Example:
“When setting up price list modifiers in Advanced Pricing, which
three steps must be completed in order to successfully activate
surcharge and price break features?”
Practitioner items present on-the-job
scenarios and require the ability to: integrate
and apply knowledge in new contexts, analyze
and troubleshoot complex issues, and solve
problems.
Example:
1) “You are creating price list modifiers in Advanced Pricing.
Your customer has three requirements: X, Y, Z. Identify the two
steps that must be completed in order to meet those requirements.
2) “You are running a two-instance database with six redo logs
defined. You decide to add a third thread to support a third
database instance, on the third node of the cluster.
Using command line administration, which two commands will
you execute to achieve this?

The CTO of your company recently heard about a feature, GNS, which can be used in an
Oracle RAC environment. He has asked you to start converting the current environment
to use this feature. Which three items need to be conveyed to the network administrator
to implement GNS?
Because each cluster should have its own GNS, it must be allocated a unique
domain on which it can run.
The GNS daemon listens on the GNS VIP using port 53 for DNS requests.
GNS virtual IP address is a static IP address configured in the DNS.
If the server on which GNS is running fails, Oracle Clusterware fails GNS
over, along with the GNS VIP, to another node in the cluster.
Both GNS daemon and the GNS VIP run on seperate node in the server cluster.

Sample Questions
You have a 3-node RAC with Flex ASM. You suspect an issue with the Flex ASM
instance on node 2. The cardinality of the Flex ASM setup is 3. You want to stop the
Flex ASM on node 2, and only that one. Which two items will accomplish this?
Run the command: [grid@server1 ~]$ srvctl modify asm -count 2
Connect to the Flex ASM instance on node 2 and do a shutdown immediate.
Look up the PMON process for the Flex ASM on node 2 and kill it.
Run the command: [grid@server1 ~]$ srvctl modify asm -count -1
Wait until all connections to the Flex ASM instance are gone and then it will stop
automatically.

Which statement about Flex Clusters and node failures is incorrect?
Nodes that are evicted from the cluster do not require a restart, only a cluster
software restart.
If a Hub node fails, the node is evicted from the cluster and services are relocated
to other Hub nodes if possible.
Leaf nodes that are associated with failed Hub nodes are not evicted from
the cluster.
If a Leaf node fails, the node is evicted from the cluster and its services are
relocated to another Leaf node where possible.
The effect of a Leaf node failure is usually contained within the group of Leaf
nodes connected to the same Hub node.
