You configuring has two halfi racks, one with high capacity disks and other with high perfiormance disks and high
capacity expansion halfi rack.
There are two RAC clusters, one on each halfi rack, which have separate storage grids, each consisting ofi some ofi the
storage servers in the configuration.
You are planning your deployment ofi Enterprise Manager to monitor all the components ofi this multi-rack Database
Machine, and must provide fior high availability ofi the monitoring infirastructure.
Ifi the host running the agent which has database machine targets bound to it fiails, the monitoring ofi these targets
must be another agent.
Which two are true regarding the configuration used to support this?

• A.A secondary agent may be deployed on a database server in a different cluster than the server hosting the primary
  agent.
• B.A secondary agent must be deployed on a database server in a different cluster than the server hosting the primary
  agent.
• C.Enterprise manager support must be deployed to only one Enterprise Manager Agent in each cluster.
• D.Enterprise Manager support must be deployed to all Enterprise Manager Agents in each cluster.
• E.A secondary agent must be deployed on a database server in the same cluster as the server hosting the primary
  agent.
• F.Enterprise Manager support must be deployed to at least two Enterprise Manager Agents in each ofi the two RAC
  clusters.

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

Which two are regarding the case ofi storage indexes?

• A.To maximize the benefit ofi storage Indexes, load your data stored on the filtered columns.
• B.Storage indexes are retained after a cell is rebooted.
• C.To increase the chance ofi using the a storage index, you can make table indexes invisible.
• D.Avoid the use ofi bind variables because Storage Indexes do not work with bind variables.
• E.The cell physical 10 bytes saved by storage index statistic returns multiple rows, one fior each storage server.

Identity the resource bottleneck fior which QoS Management can generate recommendation?

• A.CPU resource bottlenecks
• B.Global Cache resource bottlenecks
• C.I/O resource bottlenecks
• D.Network resource bottlenecks

Identifiy two valid reasons fior creating multiple griddisks on a Single celldisk.

• A.To fiacilitate normal or high redundancy ASM diskgroups
• B.To segregate storage into multiple pools that can be assigned to different resource consumer groups in the same
  database.
• C.To enable disk mirroring fior the system area
• D.To segregate storage into multiple pools with different perfiormance characteristics
• E.To segregate storage into multiple pools that can be assigned to different databases
