NO.2 Which three statements are true about bulk data loading capabilities in an X5 Database
Machine environment?
A. ACFS may be used if Exadata-based shared storage is required to stage data before bulk loading
into a database.
B. DBFS must use the DBFS_DG diskgroup for any DBFS store.
C. ACFS may use the DBFS_DG diskgroup to contain the ADVM volume file.
D. DBFS may be used if Exadata-based shared storage is required to stage data before bulk loading
into a database.
E. DBFS must be used to have a POSIX-compliant shared storage solution that is accessible from the
database servers on a Database Machine.
F. ACFS must be used to have a POSIX -compliant shared storage solution that is accessible from the
database servers on a Database Machine.
G. DBFS must be used to bulk load data into a production database on the Database Machine.
Answer: D,E,G

Explanation:
External tables on DBFS file-systems provide the probably the most high-performance way to bulk
load data into your database.
Bulk Data Loading
Describe the various options for staging data to be bulk loading into Database Machine
Configure the Database File System (DBFS) feature for staging input data files
Use external tables based on input data files stored in DBFS to perform high-performance data loads.
NO.3 You must apply patches and patch bundles in a rolling fashion, if possible, on the components
of your Exadata X6 Database Machine.
You use RAC for your databases and also use Data Guard, having standby databases on another
Database Machine.
You want to have scripts that contain the appropriate commands to patch your environment.
Your patch bundle is one the first database server and is located at/uo1/stage.
You have downloaded the oplan utility to the first database server and run:
$ORACLE_HOME/oplan/oplan generateApplySteps /u01/stage
Which two statements are true concerning the type of instructions oplan will generate?
A. Instructions for patching the Grid Infrastructure home on the primary location
B. Instructions for patching all components on the Database Machine
C. Instructions for patching the RAC Oracle Home on the primary location
D. Instructions for patching the Data Guard environment on the standby location
E. Instructions for patching only storage servers
Answer: A,C

NO.4 Which two statements are true about the use of Intelligent Platform Management Interface
(IPMI) on an X5 or X6 Database Machine?
A. IPMI can be used for server configuration and management on each database server.
B. IPMI can be used for server configuration and management on each storage server.
C. The Baseboard Management Controller (BMC), which supports IPMI, runs as a multithreaded
process on the storage server O/S.
D. The Baseboard Management Controller (BMC), which supports IPMI, runs as a single- threaded
process on the storage server O/S.
Answer: A,D
1z1-070 一番 1z1-070 科目
Explanation:
A: IPMI - short for Intelligent Platform Management Interface - is an interface standard that allow
s remote management of a server from another using standardized interface.
The servers in the Exadata Database Machine follow that. It's not an Exadata command but rather a
general Linux one.
To power on a cell or database server, issue this from another server:
# ipmitool -H prolcel01-ilom -U root chassis power on
To stop a server, use the shutdown command. To stop immediately and keep it down, i.e.
not reboot, execute:# shutdown -h -y now
C: Like the KCS interface, the SSIF Interface is only specified as a 'Single Threaded
Interface' for standard IPMI commands. That is, the BMC implementation is not expected to process
more than one IPMI request at a time. While an implementation is allowed to have a degree of
'command queuing', for standard IPMI messages the SSIF lacks a 'Seq' field that software can use to
match up particular instances of requests with responses.
