89. Frage
You are going to perform a hot remote clone of PDB1 from CDB1 as TESTPDB in CDB2. Which of the following is a necessary prerequisite for the hot remote clone?
- A. PDB1 must be taken offline before the cloning process begins.
- B. PDB1 must be in read-only mode.
- C. Both CDBs need to be in local undo mode.
- D. TESTPDB must be in read-only mode after the cloning process is complete.
Antwort: B
Begründung:
C .True. Hot cloning requires the source PDB (PDB1) to be read-only to ensure consistency during the clone. Others are not prerequisites.
90. Frage
Which three statements are true about the tools used to configure Oracle Net Services?
- A. Enterprise Manager Cloud Control can be used to centrally configure net service names for any database server target.
- B. Oracle Net Manager can be used to centrally configure listeners on any database server target.
- C. Enterprise Manager Cloud Control can be used to centrally configure listeners on any managed database server.
- D. Oracle Net Manager can be used to locally configure naming methods on a database server.
- E. The Oracle Net Configuration Assistant is only used when running the Oracle installer.
- F. The lsnrctl utility requires a listener.ora file to exist before it is started.
Antwort: A,C,D
Begründung:
A .False. Net Manager is local, not centralized.
B .False. NetCA can run standalone.
C .True. EMCC manages service names centrally.
D .True. EMCC configures listeners on managed targets.
E .False. lsnrctl starts a default listener if no listener.ora exists.
F .True. Net Manager configures local tnsnames.ora.
91. Frage
You have connected to the CDB root as a common user with the CREATE PLUGGABLE DATABASE system privilege and issued the following command: SQL> CREATE PLUGGABLE DATABASE pdb1 ADMIN USER admin1 IDENTIFIED BY p1 ROLES = (CONNECT) FILE_NAME_CONVERT = ('PDB$SEEDdir', 'PDB1dir'); Which three are results of the CREATE command?
- A. It creates tablespaces to store metadata.
- B. It creates a new local user ADMIN with restricted privileges.
- C. It creates new default schemas for the PDB.
- D. After the PDB is created, it is automatically opened Read/Write.
- E. The PDB must be opened Read Only to complete the integration of the PDB into the CDB.
- F. It creates a new local user ADMIN with SYSDBA privileges.
Antwort: A,B,C
Begründung:
A .True. PDBs inherit default schemas from the seed.
B .True. Metadata tablespaces (e.g., SYSTEM, SYSAUX) are created.
C .False. ADMIN1 (not ADMIN) isn't granted SYSDBA.
D .False. No read-only requirement post-creation.
E .False. PDBs start in MOUNTED state, not open.
F .True. ADMIN1 is a local user with CONNECT role only.
92. Frage
Which statement is true about database links?
- A. A public database link can be created only by SYS.
- B. A database link can be created only between two Oracle databases.
- C. Private database link creation requires the same user to exist in both the local and the remote databases.
- D. A public database link can be used by any user allowing remote database instance connection for selecting schema data.
- E. A database link created in a database allows a connection from that database's instance to the target database's instance for selecting schema data.
Antwort: E
Begründung:
A .False. Links can connect to non-Oracle DBs via gateways.
B .False. No such user requirement; authentication is separate.
C .False. Any user with CREATE PUBLIC DATABASE LINK can create one.
D .True. Links enable remote schema access (e.g., SELECT * FROM emp@remote).
E .False. Public links allow access, but privileges on remote objects are needed.
93. Frage
Examine these commands:
[oracle@host01 ~]$ sqlplus u1/oracle
SQL> SELECT * FROM emp;
ENO ENAME DN
-------------------------
1 Alan 2
2 Ben 2
SQL> exit
[oracle@host01 ~]$ cat emp.dat
1, Alan, 2
3, Curl, 4
4, Bob, 4
[oracle@host01 ~]$ sqlldr u1/oracle TABLE=emp
Which two statements are true?
- A. It generates a SQL script that it uses to load data from EMP.DAT to EMP.
- B. It appends data from EMP.DAT to EMP.
- C. It overwrites the data for Alan and adds data for Curl and Bob.
- D. It overwrites all data in EMP with data from EMP.DAT.
- E. It generates a log that contains control file entries, which can be used with normal SQL*Loader operations.
Antwort: B,E
Begründung:
SQL*Loader (sqlldr) loads data from external files into Oracle tables. The command sqlldr u1/oracle TABLE=emp uses defaults since no control file is specified. Let's evaluate:
A . It overwrites the data for Alan and adds data for Curl and Bob.
False. SQLLoader's default mode is APPEND, not REPLACE. It doesn't "overwrite" existing rows unless REPLACE or TRUNCATE is specified in a control file. Here, row 1, Alan, 2 exists, and SQLLoader will either skip it (if a primary key rejects duplicates) or raise an error, but it won't overwrite. 3, Curl, 4 and 4, Bob, 4 are appended.
Mechanics:Without a control file, SQL*Loader assumes APPEND and matches columns positionally (ENO, ENAME, DN).
B . It generates a log that contains control file entries, which can be used with normal SQL*Loader operations.
True. SQL*Loader always generates a log file (e.g., emp.log) when invoked. With no control file specified, it auto-generates one internally and logs it, including entries like LOAD DATA INFILE 'emp.dat' APPEND INTO TABLE emp FIELDS TERMINATED BY ',' (ENO, ENAME, DN). This can be reused.
Practical Use:The log's control section is editable for future runs (e.g., changing to REPLACE).
C . It appends data from EMP.DAT to EMP.
True. Default behavior without a control file is APPEND, adding new rows (3, Curl, 4 and 4, Bob, 4) to EMP. Existing rows (1, Alan, 2, 2, Ben, 2) remain unless constrained (e.g., unique key violations).
Mechanics:SQL*Loader processes each line of emp.dat, skipping duplicates if constrained, appending otherwise.
D . It generates a SQL script that it uses to load data from EMP.DAT to EMP.
False. SQL*Loader doesn't generate SQL scripts; it uses direct path or conventional path loading, not SQL scripts. The log contains control file syntax, not a script.
E . It overwrites all data in EMP with data from EMP.DAT.
False. REPLACE or TRUNCATE would overwrite, but these require a control file with those options. Default APPEND preserves existing data.
