a statement that consumes at least 1 second of CPU or I/O time.

a statement that consumes at least 5 second of CPU or I/O time.

any DDL statement

Question 9

Oracle databases come with a built-in health monitor to run diagnostic checks on components of the database. Which three capabilities can be used to automate reporting?

variety of real-time reports once the Business Intelligence option is installed

reports in response to critical errors

reports with findings and recommendations to resolve problems

reports examining memory and process usage

historical reports after the Database Diagnostic Repository (DDR) is configured

reports examining user and developer SQL programming errors

Question 10

Which three are SQL Performance Analyzer capabilities that enable forecasting impact of system changes on a SQL workload?

measuring performance before and after the change

generating a list of SQL Hints that the Optimizer will use to improve overall performance

identifying the SQL statements that regressed or improved

providing tuning recommendations for each SQL statement that is regressed

measuring performance and comparing to industry benchmarks (TPC-C, TPC-D)

measuring a change in user session logins

Question 12

An Oracle Database customer's VP of Development mentions that they've moved to AGILE development methodology and DevOps requires an ability to view, test, or validate performance in their own development environment. Which two do you implement?

Oracle Application Infrastructure Tester

Oracle Application Testing Suite

SQL Developer

Oracle Real Application Testing

APEX and SQL Developer

Oracle Testing Pack

Question 13

To isolate performance problem in an Oracle real Application Cluster, for which two abilities would you implement Oracle Diagnostics Pack for Oracle Databases?

Cluster-wide performance analysis and reports with ADDM on issues that affect an entire databaseas wellas its individual instances.

Database-wide analysis of global resources by ADDM for high-load SQL, global cache interconnect traffic,and skew in instance response times.

Question 14

What are two reasons for which the Diagnostics and Tuning packs are essential to ongoing maintenance of an Oracle Database?

With Diagnostics and Tuning Packs installed, an Oracle database recovers easily from a crash orcorruption.

Oracle Databases are constantly changing; more users, data added and deleted, varying SQL atapplication level.

Diagnostics and Tuning Packs are needed to keepOracle Database table and index statistics current.

Inefficient “Bad” application SQL can be detected by Diagnostics Pack and then optimized utilizing TuningPack SQL Profiles, even if it can\'t be changed at the application end.

Diagnostics and Tuning packs are a prerequisite for a customer to license Oracle Database EnterpriseEdition.
