What does the following command do?
root@rul6 -]# for j in {01..23} ; do ipmitool sunoem cli "set /SP/network/test ping=192.168.1.1$j'' ; done

• A.Sets the test address for the RoCE network for all storage and database servers in a full rack Exadata X9M-2, run from the first database server.
• B.Sets the address for each storage and database server's /SP during installation to enable ping testing from the management network, run from the first database server.
• C.Verifies that the ILOM management network is working after OEDA configuration has completed for all storage and database servers in a full rack Exadata X9M-2, run from the first database server.
• D.Verifies that the ILOM management network is working before installation of all storage and database servers in a full rack Exadata X9M-2, run from the first database server.

You are updating your Exadata X9M-2 Elastic Database Machine with 6 database servers and 12 High Capacity Storage Servers. You will be using patchmgr to apply updates across the entire machine while still maintaining database availability.
Assuming you are driving patchmgr from an external server, which statement is true about the execution phase?

• A.patchmgr must be invoked with the -rolling argument with all database and storage servers listed in a single input file.
• B.patchmgr will apply patches in component groups consisting of 1 database server and 2 storage servers to minimize disruption.
• C.patchmgr cannot apply updates in a rolling manner, you must manually apply patches with the dbnodeudpate and cellupdate tools if high availability is required.
• D.patchmgr must be invoked with the -rolling argument. Each component type must be upgraded independently of the other.

You are working on a remote Exadata Database Machine with current software and firmware. You now need to start a storage server after hardware maintenance.
Which ILOM command starts the storage server?

• A.-> start /SYS/power
• B.-> start /SYSTEM/power
• C.You must be physically present in the data center to start an Exadata Storage Server.
• D.-> start /SP/console
• E.-> start /System
• F.-> set /SYS power_state=ON

Which four actions should you take before proceeding with applying updates to your Exadata Database Machine?

• A.For database servers, perform a server backup using patchmgr -dbnodes db_list_file -backup -rolling.
• B.Consult My Oracle Support note 888828.1 to determine the current recommended Exadata software release.
• C.Run the appropriate patchmgr preqequisite check step for each component being updated.
• D.Run exachk and resolve only WARNINGS that you have not seen before.
• E.Run patchmgr --all_comp -autofix -autobackup -upgrade -rolling.
• F.Check the Exadata Critical Issues My Oracle Support note 1270094.1 for any issues not added to the latest version of exachk.

How is Exadata Secure RDMA Fabric isolation used in X9M-2 with virtualization enabled?

• A.With Secure Fabric isolation, each Storage Server runs multiple KVM guests each dedicated to a Database VM cluster using a dedicated network partition and VLAN ID. This provides security and isolation between multiple tenants or VM clusters.
• B.With Secure Fabric isolation, each Database VM Guest uses a dedicated network partition and VLAN ID for client networking between application servers. This improves security by preventing man in the middle attacks.
• C.With Secure Fabric isolation, each Database VM Cluster uses a dedicated network partition and VLAN ID for Data Guard networking between the primary and disaster recovery Exadata racks. This improves security by isolating data guard traffic onto an encrypted network between data centers.
• D.With Secure Fabric isolation, each Database VM cluster uses a dedicated network partition and VLAN ID for cluster networking between the database servers in the VM Cluster. This provides security and isolation between multiple tenants or VM clusters.
