What can be automatically implemented after the SQL Tuning Advisor is run as part of the
Automated Maintenance Task?
A.
statistics recommendations
B.
SQL profile recommendations
C.
SQL statement restructure recommendations
D.
creation of materialized views to improve query performance
Explanation:
Well, as per the below url from oracle, it says only SQL Profiles can be automatically updated,
https://docs.oracle.com/cd/B28359_01/server.111/b28274/sql_tune.htm#CHDJDFGE
2.Tune each SQL statement individually by calling the SQL Tuning Advisor.
During the tuning process, all recommendation types are considered and reported, but only SQL profiles can be implemented automatically.
Is this answer correct ?

Can you check this.. it looks like SQL statement restructure recommendations is correct
https://docs.oracle.com/cd/B28359_01/server.111/b28274/sql_tune.htm#CHDIBFGA
17.2 SQL Tuning Advisor
The SQL Tuning Advisor takes one or more SQL statements as an input and invokes the Automatic Tuning Optimizer to perform SQL tuning on the statements. The output of the SQL Tuning Advisor is in the form of an advice or recommendations, along with a rationale for each recommendation and its expected benefit. The recommendation relates to collection of statistics on objects, creation of new indexes, restructuring of the SQL statement, or creation of a SQL profile. You can choose to accept the recommendation to complete the tuning of the SQL statements. (There are only recommendation, not automated by left as optional)
Further it says what can be automated , in the continuation below
Oracle Database can automatically tune SQL statements by identifying problematic SQL statements and implementing tuning recommendations using the SQL Tuning Advisor during system maintenance windows. You can also run the SQL Tuning Advisor selectively on a single or a set of SQL statements that have been identified as problematic.
B
During the tuning process, all recommendation types are considered and reported, but only SQL profiles can be implemented automatically.
