A read-only application is in development and is using a test database on a Database Machine. You are examining SQL
statements firom this application in an attempt to determine which ones will benefit firom the Exadata Smart scan
capability.
The fiollowing is true about the tables used by the application:
1. The data fior the tables has just been loaded.
2. There are no applications accessing the tables currently.
3. None ofi the indexes are compressed or reverse key indexes.
4. The tables use the defiault organization type data.
5. The only data types fior the table are varchar (2), number, or date.
6. The largest number ofi columns fior any table is 29.
7. No access is based on ROWID, or virtual columns.
Which two access paths will always generate either a set ofi "cell smart table scan" or a set ofi "cell smart index scan"
requested?
- A. Full table scans on heap tables executed in parallel
- B. fiull scans on hash clustered tables executed in serially
- C. fiast fiull scans on B*Tree indexes executed in parallel
- D. Full scans on sorted hash clustered tables executed in parallel
- E. Full scans on index clustered tables executed in parallel
- F. fiull index scans on B*Tree indexes executed in parallel
- G. Full table scans on index organized tables executed in parallel.
Correct Answer: A,C 🗳️
You plan to migrate an existing production database supporting online transaction processing (OLTP) workloads to the
Exadata Database Machine. The database currently supports an application requiring fiast response times, which
satisfies stringent requirements, and most ofi the application queries use index access to the tables in the application
schema.
For which case would you consider dropping indexes to allow Smart Scans to occur?
- A. Drop non-constraint indexes ifi Smart Scan perfiorms better than index unique scans on the corresponding table.
- B. Drop non-constraint Indexes ifi Smart Scan perfiorms better than any index scans on the corresponding table.
- C. Drop non-constraint indexes ifi Smart Scan perfiorms better than index range scans on the corresponding table.
- D. Drop non-constraint indexes ifi Smart Scan occurs instead ofi an index access path on the corresponding table.
Correct Answer: B 🗳️

3. Power off all network switches using their power switch.
4. Execute "crsctl stop cluster -all" as the root user firom one database server.
5. Execute "crsctl stop cluster -all" as the grid user firom one database server.
6. Power off the rack using the power switches on the PDUs.
7. Execute "shutdown -h now" on all database servers.

- A. a query rewrite may occur to a container table stored in Exadata but will never benefit From Smart scan.
- B. Some joins can be offloaded to the storage servers.
- C. It is possible to offload single row fiunctions to the storage servers.
- D. A query rewrite may occur to a container table stored Exadata, and it will always benefit firom Smart Scan.
- E. Column projection does not contribute to the perfiormance benefit ofi Smart Scan
- F. All joins can be offloaded to the storage servers.
