At ValidExamDumps, we consistently monitor updates to the Oracle 1Z0-062 exam questions by Oracle. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the Oracle Database 12c: Installation and Administration exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by Oracle in their Oracle 1Z0-062 exam. These outdated questions lead to customers failing their Oracle Database 12c: Installation and Administration exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the Oracle 1Z0-062 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.

A warehouse fact table in your Oracle 12c Database is range-partitioned by month and accessed frequently with queries that span multiple partitions
The table has a local prefixed, range partitioned index.
Some of these queries access very few rows in some partitions and all the rows in other partitions, but these queries still perform a full scan for all accessed partitions.
This commonly occurs when the range of dates begins at the end of a month or ends close to the start of a month.
You want an execution plan to be generated that uses indexed access when only a few rows are accessed from a segment, while still allowing full scans for segments where many rows are returned.
Which three methods could transparently help to achieve this result? (Choose three.)
Note:
* Oracle 12c now provides the ability to index a subset of partitions and to exclude the others.
Local and global indexes can now be created on a subset of the partitions of a table. Partial Global indexes provide more flexibility in index creation for partitioned tables. For example, index segments can be omitted for the most recent partitions to ensure maximum data ingest rates without impacting the overall data model and access for the partitioned object.
Partial Global Indexes save space and improve performance during loads and queries. This feature supports global indexes that include or index a certain subset of table partitions or subpartitions, and exclude the others. This operation is supported using a default table indexing property. When a table is created or altered, a default indexing property can be specified for the table or its partitions.
You set the following parameters in the parameter file and restart the database instance:
Which two statements are true? (Choose two.)
You install Oracle Grid Infrastructure for a standalone server.
Which two components are automatically included in the Oracle Restart configuration? (Choose two.)
