QUESTION 1
Which statement is true about operating systems in an X5 Database Machine multirack configuration consisting of two full racks and one Exadata storage expansion rack?
A. All Exadata storage servers used by the same virtual cluster nodes must run the same O/S but Exadata Storage Servers in different clusters may run different operating systems.
B. All Exadata storage servers must run the Oracle Solaris O/S and all database servers within the same cluster must run Oracle Linux.
C. All Exadata storage servers may run Oracle Virtual Machine (OVM).
D. All Exadata storage servers must run Oracle Linux.
E. All Exadata storage servers must run the Oracle Linux O/S and all database servers within the same cluster must run the same version of Oracle Virtual Machine (OVM).
Answer: D
Explanation:
On both physical and virtual deployments, Exadata systems use minimal Linux distributions to ensure that just the RPMs needed to run Oracle database, are installed and enabled.

QUESTION 2
You installed ASR Manager on a stand-alone server and configured Auto Service Request (ASR) for your X5 Database Machine and its assets.
Which three statements are true about this configuration?
A. Simple Network Management Protocol (SNMP) traps are used to send notifications from
database servers to the ASR Manager.
B. Simple Network Management Protocol (SNMP) traps are used to send notifications from storage servers to the ASR Manager.
C. When a component fault occurs, fault telemetry is securely transmitted to Oracle via Simple Network Management Protocol (SNMP).
D. When a component fault occurs, fault telemetry is securely transmitted to Oracle via HTTPS.
E. Simple Network Management Protocol (SNMP) traps are used to send notifications from the Enterprise Manager to the ASR Manager.
F. Simple Network Management Protocol (SNMP) traps received by ASR Manager are forwarded to the Enterprise Manager.
Answer: B,C,F
Explanation:
B: Oracle ASR Manager only processes SNMP traps that are sent from IP addresses that Oracle ASR Manager recognizes.
Example of Exadata Storage Server SNMP Trap
This example shows the SNMP trap for an Exadata Storage Server disk failure. The corresponding hardware alert code has been highlighted.
2011-09-07 10:59:54 server1.example.com [UDP: [192.85.884.156]:61945]: RFC1213-MIB::sysUpTime.0 = Timeticks: (52455631) 6 days, 1:42:36.31 SNMPv2-SMI::snmpModules.1.1.4.1.0 = OID: SUN-HW-TRAP-MIB::sunHwTrapHardDriveFault
SUN-HW-TRAP-MIB::sunHwTrapSystemIdentifier = STRING: Sun Oracle Database Machine Etc.
C (not D): The ASR Manager uses the SNMP GET protocol to query ASR assets for additional fault information.
To configure fault telemetry, choose one of the following three options:
Add SNMP Trap Destinations Using OneCommand (recommended for new installations) Add SNMP Trap Destinations for Multiple Servers Using the dcli Utility
Add SNMP Trap Destinations for a Single Server

QUESTION 3
Which three are true concerning Smart Scans?
A. The decision to perform a Smart Scan is made by the Optimizer.
B. Smart Scans are only possible during full table scans or fast full index scans.
C. Smart Scans are possible on Index Organized Tables (IOTs).
D. Smart Scans always outperform scans that are not offloaded.
E. Smart Scans are possible on heap organized tables.
F. Smart Scans are possible on uncompressed B*Tree indexes.
Answer: A,B,F
Explanation:
B: In order for queries to take advantage of Exadata’s Offloading capabilities, the optimizer must decide to execute a statement with a Full Table Scan or a Fast Full Index Scan.
F: Smart Scans can be used for full scanning through B*Tree index segments.
