Oracle Database Administration II 認定 1Z0-083 試験問題 (Q218-Q223):

質問 # 218
Which two are true about the Automatic Database Diasnostic Monitor (ADDM)? (Choose two.)

正解：A、B

解説：
An ADDM analysis task is performed and its findings and recommendations stored in the database every time an AWR snapshot is taken provided the STATISTICS_LEVEL parameter is set to TYPICAL or ALL.
The time period analyzed by ADDM is defined by the last two snapshots (the last hour by default).


質問 # 219
Which three are true about Automatic Workload Repository (AWR), Automatic Database Diagnostic Monitor (ADDM), and the Manageability Monitor (MMON) background process?
(Choose three.)

正解：A、B、E

解説：
AWR Snapshot's default interval is 1 hour and retention is 8 days. It means All AWR statistics are collected every 1 hour and they are kept 8 days by default.


質問 # 220
A container database called CDB1is OMF-enabled.
PDB_FILE_NAME_CONVERTis not configured in CDB1.
PDB1was unplugged from CDB1earlier in the week.
Examine this command, which will be executed in CDB1:
CREATE PLUGGABLE DATABASE pdb1
USING '/u01/app/oracle/oradata/pdb1.xml'
SOURCE_FILE_NAME_CONVERT =
('/u01/app/oracle/oradata/', '/u02/app/oracle/oradata/');
Which two are true? (Choose two.)

正解：B、C

解説：
The question gives the impression that the source files were held at /u01/app/oracle/oradata, but are now physically located at /u01/app/oracle/oradata. The xml description file is still at
/u01/app/oracle/oradata/pdb1.xml
A: FALSE - SOURCE_FILE_NAME_CONVERT is only needed if the XML file does not accurately describe the current location of the pdb's files.
B: FALSE - If pdb1 ran correctly before, it will run correctly now - assuming that no major upgrade of CDB1 has happened.
C: FALSE - PDB_FILE_NAME_CONVERT is needed only when OMF is not used. The question tells us that OMF is enabled.
D: TRUE - The use of the SOURCE_FILE_NAME_CONVERT parameter indicates that the DB files have been moved, so the xml file does not hold the correct locations E: TRUE - Unplugging a database will result in the PDB remaining in a MOUNT state. It is still part of the CDB and will still be backed up etc... After unplugging, a PDB needs to be dropped before a new PDB can be created with the same name.


質問 # 221
Which two are true about Oracle Grid Infrastructure for a Standalone Server? (Choose two.)

正解：A、C


質問 # 222
Which three are true about the Oracle Optimizer? (Choose three.)

質問 # 223
