You are checking the status ofi the ports on the one ofi the InfiniBand switches in your Database Machine.
You have run the getportstatus as shown:

You have 36 ports to check.
Which two methods would you use to check the status ofi all 36 ports?

• A.Use Enterprise Manager.
• B.Use Database Control.
• C.Use the ibqueryerros.pl script logged into the InfiniBand switch as root.
• D.Create user-defined metrics fior the InfiniBand switch.

You are in the planning stage ofi the network configuration fior your Database Machine. The requirements are:
1. A fiault-tolerant network, providing higher availability fior connections to database instances
2. Fault tolerance providing higher availability fior connections to perfiorm management fiunctions on the database and
storage servers.
3. Full monitoring ofi all Database Machine components using Enterprise Manager
Which three components require external Ethernet network cables to connect your existing network infirastructure to
your database machine to satisfiy this requirement?

• A.Database servers
• B.Exadata storage servers
• C.InfiniBand storage servers.
• D.Power distribution units (PDUs)
• E.Cisco Ethernet switch

Yesterday, an Exadata storage server flashdisk entered the poor perfiormance state.
This flashdisk os used by flashcache and has a griddisk which is a member ofi a normal redundancy diskgroup.
Identifiy the six steps you must perfiorm to replace flashdisk.

• A.Identifiy the griddisk located on the poorly perfiorming flashdisk and drop it firom the associated ASm diskgroup.
• B.Safiely power off the cell containing the poorly-perfiorming flashdisk.
• C.Power up the cell containing the replaced flashdisk and activate all griddisks.
• D.Add the griddisk back into the ASM diskgroup to which it belonged.
• E.Verifiy that the griddisk located on the poorly perfiorming flashdisk has been successfiully dropped firom the
  associated ASM diskgroup.
• F.Replace the poorly perfiorming flashdisk.
• G.Create a new griddisk on the replaced flashdisk.
• H.Drop the flashcache on all cell.
• I.Recreate the flashcache on the cell using all flashdisks.

You plan to migrate a database supporting an an OLTP workload to your Database Machine
This is part ofi a consolidation project and several other databases already exist on the Database Machine.
Which three Exadata fieatures may help to improve the perfiormance ofi this OLTP workload?

• A.Smart Scan
• B.Hybrid Columnar Compression
• C.Smart Flash Log
• D.Smart Flash Cache
• E.I/O Resource Manager
• F.Storage Index

Which three are true regarding the use ofi Storage Indexes?

• A.Storage Indexes occupy space in the Smart Flash Cache.
• B.A maximum ofi eight table columns fior any table are Indexed per storage region.
• C.The use ofi Storage Indexes fior particular categories ofi I/O can be disabled by using an I/O Resource Manager
  Category Plan.
• D.Different storage regions may have different columns indexed fior the same table.
• E.The use ofi Storage indexes fior a particular database can be disabled by using an I/O Resource Manager Database
  Plan.
• F.A Storage index is automatically maintained by CELLSRV based on the filter columns ofi the offload SQL.
