In the spfile of a single instance database, LOCAL_LISTENER is set to LISTENER_1.
The TNSNAMES.ORA file in $ORACLE_HOME/network/admin in the database home contains:
Which statement is true?
Dynamic service registration cannot be used for this database instance The LREG process registers services dynamically with the LISTENER_1 listener LISTENER_1 must also be defined in the LISTENER.ORA file to enable dynamic service registration There are two listeners named LISTENER and LISTENER_1 running simultaneously using port 1521 on the same host as the database instances The definition for LISTENER_1 requires a CONNECT_DATA section to enable dynamic service registration.

Which three functions are performed by dispatchers in a shared server configuration? (Choose three.) writing inbound request to the common request queue from all shared server connections checking for outbound shared server responses on the common outbound response queue receiving inbound requests from processes using shared server connections sending each connection input request to the appropriate shared server input queue broadcasting shared server session responses back to requesters on all connections sending shared server session responses back to requesters on the appropriate connection.
Which two statements are true about the SET VERIFY ON command? (Choose two.) It can be used only in SQL*Plus It displays values for variables used only in the WHERE clause of a query It can be used in SQL Developer and SQL*Plus It displays values for variables created by the DEFINE command It displays values for variables prefixed with &&.

You want to write a query that prompts for two column names and the WHERE condition each time it is executed in a session but only prompts for the table name the first time it is executed. The variables used in your query are never undefined in your session.
Which query can be used? SELECT &&col1, &&col2 FROM &table WHERE &&condition = &&cond; SELECT &col1, &col2 FROM &&table WHERE &condition; SELECT &col1, &col2 FROM ג€&tableג€ WHERE &condition; SELECT '&&col1', '&&col2' FROM &table WHERE '&&condition' = '&cond'; SELECT &&col1, &&col2 FROM &table WHERE &&condition;.

Examine this command:
Which two statements are true? (Choose two.) DML may be performed on tables with one or more extents in this data file during the execution of this command. The tablespace containing SALES1.DBF must be altered READ ONLY before executing the command. The tablespace containing SALES1.DBF must be altered OFFLINE before executing the command. If Oracle Managed Files (OMF) is used, then the file is renamed but moved to DB_CREATE_FILE_DEST. The file is renamed and stored in the same location.
Which three statements are true about dropping and unused columns in an Oracle database? (Choose three.) A primary key column referenced by another column as a foreign key can be dropped if using the CASCADE option. An UNUSED column's space is reclaimed automatically when the block containing that column is next queried. An UNUSED column's space is reclaimed automatically when the row containing that column is next queried. Partition key columns cannot be dropped. A DROP COLUMN command can be rolled back A column that is set to UNUSED still counts towards the limit of 1000 columns per table.
Which two statements are true regarding Oracle database space management within blocks managed by Automatic Segment Space Management (ASSM)? (Choose two.) PCTFREE defaults to 10% for all blocks in all segments for all compression methods ASSM assigns blocks to one of four fullness categories based on what percentage of the block is allocated for rows Update operations always attempt to find blocks with free space appropriate to the length of the row being updated Insert operations always attempt to find blocks with free space appropriate to the length of the row being inserted .A block will always be eligible for inserts if the row is short enough to fit into the block.
Evaluate these commands which execute successfully:
Which two statements are true about the ORD_ITEMS table and the ORD_SEQ sequence? (Choose two.) If sequence ORD_SEQ is dropped then the default value for column ORD_NO will be NULL for rows inserted into ORD_ITEMS Any user inserting rows into table ORD_ITEMS must have been granted access to sequence ORD_SEQ Column ORD_NO gets the next number from sequence ORD_SEQ whenever a row is inserted into ORD_ITEMS and no explicit value is given for ORD_NO Sequence ORD_SEQ cycles back to 1 after every 5000 numbers and can cycle 20 times Sequence ORD_SEQ is guaranteed not to generate duplicate numbers.

(Choose three.) two or more instances on separate servers all associated with one database one instance on one server associated with one database one instance on one server associated with two or more databases on the same server one instance on one server not associated with any database one instance on one server associated with two or more databases on separate servers.
Which two statements are true about the ORDER BY clause when used with a SQL statement containing a SET operator such as UNION? (Choose two.) Column positions must be used in the ORDER BY clause Only column names from the first SELECT statement in the compound query are recognized The first column in the first SELECT of the compound query with the UNION operator is used by default to sort output in the absence of an ORDER BY clause Each SELECT statement in the compound query must have its own ORDER BY clause Each SELECT statement in the compound query can have its own ORDER BY clause.
