A.Install Oracle Rest Data Services on each Database server and install the MS APEX application.

B.The MS Process on the storage servers is natively endowed with REST services, but are not enabled by default.

C.Install Oracle Rest Data Services on each Storage server and install the MS APEX application.

D.The MS Process on the storage servers is natively endowed with REST services and are enabled by default, however, appropriate roles and users should be created to ensure security.

Question 7

Which of the following is NOT a requirement when validating, receiving, unpacking, and planning access route and space requirements for Exadata Database Machine?

A.All four leveling and stabilizing feet should be raised and out of the way prior to moving the rack.

B.A conditioned space is required to remove the packaging material to reduce particles before entering the data center.

C.914mm of space required above the rack height is required for maintenance access.

D.The entire access route to the installation site should be free of raised-pattern flooring that can cause vibration.

E.The incline of any access route ramp must be less than or equal to 6 degrees.

F.Oracle Exadata Rack may only be installed on raised floor environments.

Question 8

An Exadata X9M-2 Elastic Rack with 4 Database Servers and 8 HC Storage Servers and 3-phase 24kVA PDUs is being installed in a Data Center. However, the Data Center is only providing enough power for a single cable from each PDU. Which statement is correct?

A.A splitter cable can be used to provide power to all PDU cables.

B.The power cables from the servers to the PDUs can be rearranged inside the rack following OECA guidance to utilize a single PDU power cable.

C.The installation cannot proceed until two power feeds are available per PDU.

D.The installation can go ahead, no change is required.

Question 9

You are concerned about the operating temperature of the database servers in your Exadata Full Rack and want to be alerted if the server exceeds 30C.
What command should use use to generate alerts for such an event?

A.dbmcli -e "set alert ds_temp> 30" on each database server

B.dbmcli -e "set threshold ds_temp comparison=' >', critical=30" on each database server

C.dbmcli -e "alert metriccurrent ds_temp where metricValue > 30" on each database server

D.dbmcli -e "create threshold ds_temp comparison='>', critical=30" on each database server

Question 10

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 must be invoked with the -rolling argument. Each component type must be upgraded independently of the other.

C.patchmgr will apply patches in component groups consisting of 1 database server and 2 storage servers to minimize disruption.

D.patchmgr cannot apply updates in a rolling manner, you must manually apply patches with the dbnodeudpate and cellupdate tools if high availability is required.
