You must design an Oracle Data Guard configuration for a DSS database that meets these permanent requirements:
1. Creating and maintaining bitmap indexes should not impact the performance of the primary database.
2. Creating and maintaining materialized views should not impact the performance of the primary database.
Additionally, there are these requirements, only one of which is ever done at any one time:
1. It should be possible to apply designated patches with a minimum amount of downtime.
2. Upgrading to a new database release should be performed with the least possible amount of downtime.
3. New application software releases should be tested against an exact and up-to-date replica of the primary database.
Which configuration meets these requirements with the fewest of databases?
1. Creating and maintaining bitmap indexes should not impact the performance of the primary database.
2. Creating and maintaining materialized views should not impact the performance of the primary database.

Your Data Guard environment consists of these components and settings:
1. A primary database
2. A remote physical standby database
3. Real-time query is enabled.
4. The redo transport mode is set to SYNC.
5. The protection mode is set to Maximum Availability.
You notice that queries executed on the physical standby database receive errors: ORA-03172:
STANDBY_MAX_DATA_DELAY of 15 seconds exceeded. Which two would you recommend to avoid this error?

You created two remote physical standby databases using SQL and RMAN.
The primary database is a four-instance RAC database and each physical standby database has two instances.
Roles-based services are used for client connectivity and have been defined in the Grid Infrastructure.
Consider these operational requirements:
* The ability to manage multiple standby databases with a single tool
* The simplification of switchovers, failovers, reinstatements, and conversions to and from snapshot standby databases
* The automation of failovers to a specified target standby database
Which TWO tools can be used to fulfill these requirements7

A customer has these requirements for their proposed Data Guard implementation:
1. Zero data loss must still be guaranteed through the loss of any one configuration component.
2. The primary database must be protected against a regional disaster.
3. Performance overheads on the primary should be minimized as much as possible given these requirements.
4. Downtime on the primary database for any reason must be kept to a minimum.
Components referred to in the broker commands are:
1. Zero data loss must still be guaranteed through the loss of any one configuration component.
2. The primary database must be protected against a regional disaster.
3. Performance overheads on the primary should be minimized as much as possible given these requirements.
4. Downtime on the primary database for any reason must be kept to a minimum.
