QUESTION NO: 1
You are administering a database that supports an OLTP workload. The CURSOR_SHARING parameter is set to EXACT for the instance. The performance of queries issued by one of the modules has degraded. The queries executed by the module are almost identical in syntax. To investigate, you analyze the latest AWR report and find a large number of latch:shared pool wait events and also a high percentage of the hard parse elapsed time.
Which two can be reasons for this? (Choose two.)
A. The I/O performance is slow.
B. Excessive time is spent on finding cached cursors in the library cache.
C. The CURSOR_SHARING parameter is set to EXACT, which does not allow similar queries to share a cursor.
D. Bind variables are not used for similar queries, causing hard parses.
E. Repeated access to a small number of blocks.
Answer: D,E
QUESTION NO: 2
Which two statements are true about ADDM? (Choose two.)

B. It first identifies the performance symptoms, and then refines them to reach the root cause with the singular aim of reducing the DB CPU metric.
C. It analyzes the performance of a database instance based on the time period covered by the most recent AWR snapshot, and generates recommendations based on hard-coded criteria.
D. It can analyze performance issues that occurred in past events provided they fall within the AWR retention period.

PL/SQL procedure successfully completed.
SQL> CREATE INDEX COUNTRY_IDX ON CUSTOMERS (COUNTRY_ID);
Index created.
