You have two very large databases supporting OLTP workloads which run on multiple small-blade style servers in a
cluster and which require optimal latency fior I/O.
You plan to migrate them to a Database Machine once a capacity planning exercise is finished.
The database backup strategy requires that backups are written directly to media.
High availability requirements state that you must be able to survive node fiailures at any time.
Which three Database Machine components or fieatures would you recommend to support these requirements?

• A. Use ofi write back flash cache
• B. High perfiormance disks in the Database Machine
• C. High capacity disks in the Database Machine
• D. A high capacity expansion fiull rack
• E. A high perfiormance expansion fiull rack
• F. Use ofi smart flash logs

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. fiull scans on hash clustered tables executed in serially
• B. Full scans on sorted hash clustered tables executed in parallel
• C. Full scans on index clustered tables executed in parallel
• D. Full table scans on heap tables executed in parallel
• E. fiull index scans on B*Tree indexes executed in parallel
• F. fiast fiull scans on B*Tree indexes executed in parallel
• G. Full table scans on index organized tables executed in parallel.

You are examining the existing IORM configuration on the cells ofi Database Machine, to see ifi they require my
modifications based on recent changes to various workloads.
All seven cells in your X3-2 halfi-rack shown the fiollowing:

Which two are true about I/O to the cells using this plan?

• A. No I/Os in any category or firom any database may use flashing or flashcache because the objective is off.
• B. I/O requests firom the sales database may use flashing regardless ofi the I/O category.
• C. I/O requests in the batch category may use flashcache ifi the I/O is firom the sales finance database, and these I/O
  requests are guaranteed to get 80% ofi the I/O ifi the interactive category I/Os use no more than 20%.
• D. I/O requested in the interactive category may use flashdns ifi the I/O is firom the sales or finance databases, and
  these I/O requests are guaranteed to get 90% ofi the I/O ifi the enough I/Os are issued in this category.
• E. I/O requests made by sessions in the marketing database may use flashing and flashcache ifi no other categories or
  database or database are using flashing and flashcache at the same time.

You must drop all celldisks on all the cells in a quarter rack as part ofi a reconfiguration project, to support normal
redundancy interleaving.
Select two actions that describe the operating system (O/S) account on the cells to which you should log in, and the
tool that may be used to drop the celldisks.

• A. To CELLADMIN account calling CELLCLI on all cells using DCLI
• B. To the CELLADMIN account using CELLCLI interactively on each cell
• C. To either the CELLMONITOR or CELLADMIN account calling interactively on each cell
• D. To the CELLMONITOR account using CELLCLI interactively on each cell.
• E. To either the CELIMONITOR or the CELLADMIN account calling CELLCLI on all cells using DCLI
• F. To the CELLMONITOR account calling CELLCLI on all cells using DCLI

Which type ofi network traffic is transported over the internal InfiniBand network in a Database Machine?

• A. Both Clustered ASM and RAC database instance traffic
• B. IDB protocol traffic, Clustered ASM traffic, and RAC database instance traffic
• C. Clustered ASM Instance traffic only
• D. RAC database instance traffic only
• E. IDB protocol traffic only
