Demo Questions

Question 1
Batch and DSS workloads on your Exadata X6 Database Machine are causing performance problems for OLTP workloads at certain times of the day. 
There are five RAC databases performing OLTP I/O. Two of them also perform batch I/O. There is another RAC database that performs only DSS I/O. 
You are asked to resolve this problem so that the OLTP workload will not suffer when competing with the batch or DSS workloads. 
You decide to use the I/O resource manager. 
Which is the best way to solve this problem?

  • A: Create a category plan with EXADCLI calling EXACLI to give the OLTP category the highest priority on all the cells, and use the Database Resource Manager to create the OLTP category and map all OLTP- oriented consumer groups in all databases to it.
  • B: Use the Database Resource Manager to give the OLTP category the highest priority and use EXADCLI calling EXACLI to create the OLTP category on all the cells.
  • C: Create a category plan with EXADCLI calling EXACLI to give the OLTP category the highest priority on all the cells, and use the Database Resource Manager to give the OLTP consumer group the highest priority on all databases.
  • D: Create a database plan using EXADCLI calling EXACLI to give OLTP I/O the highest priority from all six databases.



Question 2
Identify three valid reasons for creating multiple griddisks on a single harddisk-based celldisk.

  • A: to implement storage realms so that storage that can be reserved for specific resource consumer groups in the same database
  • B: to enable the creation of normal or high redundancy ASM diskgroups
  • C: to segregate storage into multiple pools with different performance characteristics
  • D: to enable disk mirroring for the system area
  • E: to implement storage realms so that storage can be reserved for specific databases
  • F: to implement storage realms so that storage that can be reserved for specific Grid Infrastructure



Question 3
Which three statements are true concerning the configuration of SNMP on an Exadata x5 or x6 Database Machine?

  • A: All SNMP notifications from the storage server ILOMs are sent directly to the Automatic Service Request (ASR) manager.
  • B: Some SNMP notifications may be configured using the alter cell command on the storage servers.
  • C: The Database Machine internal Cisco Switch communicates directly with the Enterprise Manager agent via SNMP.
  • D: Some SNMP notifications from a storage server ILOM are sent directly to the management server (MS) process on the same storage servers.
  • E: All SNMP notifications from a database server ILOM are sent directly to the Automatic Service Request (ASR) manager.
  • F: All SNMP notifications from a database server ILOM are sent directly to the management server (MS) process on the same database server.



Question 4
You have partitioned an X5-2 full rack into two four-node RAC clusters called CLUSA and CLUSB. 
No virtualization is used and the storage grid has not been partitioned. 
Which two set of files on which servers must be modified after connecting an Exadata storage expansion rack to your X5-2 Exadata Database Machine on the InfiniBand network so that the storage servers in the expansion rack are added to the storage grid?

  • A: the CELLINIT.ORA files on the database servers in CLUSA
  • B: the CELLIP.ORA files on the database servers in CLUSA
  • C: the CELLINIT.ORA files on the database servers in CLUSB
  • D: the CELLIP.ORA files on all existing Exadata storage servers
  • E: the CELLIP.ORA files on the database servers in CLUSB
  • F: the CELLIP.ORA files on all newly added Exadata storage servers



Question 5
You plan to monitor the status of the motherboard, memory, power, fans, and network cards on the database nodes in your Exadata X6 Database Machine using Enterprise Manager. 
Where must you set the thresholds for these hardware components and why, to assure that sensor readings, faults, and any related alerts, are visible in Enterprise Manager?

  • A: No thresholds need to be set because they are present in the ILOM and in Enterprise Manager.
  • B: Set thresholds in ILOM and in Enterprise Manager because they are not present anywhere and must be set in both places.
  • C: Set thresholds only in ILOM because they are not preset anywhere but need to be set only in ILOM.
  • D: No thresholds need to be set because they are preset in the ILOM and these are sufficient for monitoring.



Question 6
Examine this list of software components:
Oracle Virtual Machine (OVM) 
Oracle Enterprise Manager Agent (OMA) 
ASM instance 
RDBMS instance 
Automatic Diagnostic Repository Command Interpreter (ADRCI) 
CELLCLI 
Cell Server (CELLSRV) 
diskmon 
Identify the location where these software components can run in the standard Exadata Database Machine deployment.

  • A: 1, 2, 3 and 4 run on the database servers; 5, 6, 7, and 8 run on the Exadata storage servers.
  • B: 1, 2, 3, 4, 5, and 8 run on the database servers; 5, 6, and 7 run on the Exadata storage servers.
  • C: 1, 2, 3, 4 and 8 run on the database servers; 5, 6, and 7 run on the Exadata storage servers.
  • D: 3, 4 and 8 run on the database servers; 1, 2, 5, 6 and 7 run on the Exadata storage servers.
  • E: 2, 3, 4 and 8 run on the database servers; 1, 5, 6 and 7 run on the Exadata storage servers.



Question 7
Which two statements are true regarding the use of Auto Service Request (ASR) with an X6 Database Machine?

  • A: The database server ILOMs must use SMTP over the management network for notifications to ASR Manager.
  • B: The database server ILOMs must have SNMP traps configured to use the management network for notifications to ASR Manager.
  • C: The storage server ILOMs must have SNMP traps configured to use the management network for notifications to ASR Manager.
  • D: The database server MS process must have SNMP traps configured to use the management network for notifications to ASR Manager.



Question 8
Which three statements are true regarding the configuration of Auto Service Request (ASR) on an X5 Database Machine?

  • A: ASR Manager may be installed on any type of server running Oracle Solaris.
  • B: ASR Manager may be installed on any type server running Oracle Linux.
  • C: Oracle Linux must be used on the server where ASR Manager is installed.
  • D: SMTP must be enabled on at least one database server.
  • E: Oracle Solaris must be used on the server where ASR Manager is installed.
  • F: ASR Manager must be installed on one of the database servers.
  • G: HTTPS connectivity must be enabled from the ASR Manager host to the Internet.



Question 9
Which three storage components are available after nonvirtualized standard deployment of an X5 Database Machine using high-capacity disks?

  • A: mirrored system area on hard disk 0, hard disk 1, and hard disk 2
  • B: Exadata Smart Flash Cache using all of the flashdisk space
  • C: the DBFS_DG diskgroup with high redundancy
  • D: mirrored system area on hard disk 0 and hard disk 1
  • E: the RECO_<DBM_Name> ASM diskgroup
  • F: the DATA_<DBM_Name> ASM diskgroup



Question 10
You plan to monitor the ASM configuration on an X5 Database Machine as part of your role supporting Exadata-based ASM diskgroups. 
You want to check for potential space problems that take ASM mirroring requirements into account. 
Which two values would you monitor from V$ASM_DISKGROUP or by using the ASMCMD LSDG command?

  • A: cold_used_mb
  • B: total_mb
  • C: required_mirror_free_mb
  • D: free_mb
  • E: usable_file_mb
