Last Updated: July 3rd,2024

Question 1

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.

Correct Answer:BCF
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 References: http://docs.oracle.com/cd/E80920_01/ASXQI/toc.htm

Question 2

Which two statements are true about the Enterprise Manager plug-in configuration for the X5 Database Machine?

A. There is one plug-in for Cloud Control.
B. There are several separate plug-ins for Cloud Control.
C. Some components of the Database Machine require SNMP trap forwarders.
D. All components of the Database Machine require SNMP trap forwarders.

Correct Answer:AC

Question 3

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

Correct Answer:BE
The cellip.ora is the configuration file, on every compute node (database server), that tells ASM instances which cells are available to this cluster.
The cellip.ora file contains the storage cell IP addresses.

Question 4

An Exadata storage server physical disk on an X5 high-capacity full rack entered the predictive failure state. Identify the two steps that you must perform to replace this failed physical disk.

A. Add the griddisks back into the ASM diskgroup they used to be a member of.
B. Create a new celldisk and new griddisks on the replaced physical disk.
C. Verify that the griddisks located on the physical disk have been successfully dropped from the associated ASM diskgroups.
D. Identify the griddisks located on the failed physical disk and drop them from the associated ASM diskgroups.
E. Replace the failed physical disk.

Correct Answer:CE
You may need to replace a physical disk because the disk is in warning - predictive failure status. The predictive failure status indicates that the physical disk will soon fail, and should be replaced at the earliest opportunity. The Oracle ASM disks associated with the grid disks on the physical drive are automatically dropped, and an Oracle ASM rebalance relocates the data from the predictively failed disk to other disks.
Note: After the physical disk is replaced, the grid disks and cell disks that existed on the previous disk in that slot are re-created on the new physical disk. If those grid disks were part of an Oracle ASM group, then they are added back to the disk group, and the data is rebalanced on them, based on the disk group redundancy and ASM_POWER_LIMIT parameter.

Question 5

You plan to consolidate multiple mission-critical databases onto a single rack Exadata X6 Database Machine. You do not plan to use virtualization on the database servers.
You have identified two database categories, based on differing availability and maintenance objectives. Which two choices will be the best solution?

A. Create a single database cluster that accesses a single storage grid.
B. Create a single database cluster that accesses multiple storage grids.
C. Partition the Exadata storage servers into two separate storage grids.
D. Create a single storage grid and share space on the celldisks using Exadata storage realms.
E. Partition the database servers into two separate clusters.

Correct Answer:BE
