Question 16

Which four statements are true concerning the configuration or use of Enterprise Manager Cloud Control to monitor and manage Exadata Database Machine components?

A. Computer nodes forward their SNMP traps to the Management Server process on the same computer node.
B. Storage nodes forward their SNMP traps to the Management Server process on the same storage node.
C. Cloud control can monitor and manage a Database Machine compute node expansion rack.
D. Oracle management agents must only be installed on one storage node in a Database Machine to enable monitoring and management of all storage nodes.
E. Cloud Control cannot monitor partitioned Exadata Database Machine systems.
F. Cloud Control can monitor and manage a Database Machine storage Expansion rack.
G. Oracle management agents must only be installed on one compute node in a Database Machine to enable monitoring and management of all compute nodes and storage nodes.

Correct Answer:BCFG
B (not A): Oracle Exadata components—including database and storage servers, switches, and power distribution units (PDUs)—use SNMP to raise alerts and report monitoring information.
Oracle’s CellCLI interface is a Java-based framework delivered by the storage cell’s management server process (MS) that provides administrative capabilities to your storage server entities.
C: Cloud control can monitor the Exadata Database Machine.
Figure: Oracle Enterprise Manager Cloud Control 12c monitoring architecture. Note the Management Server process (MS) on the Storage servers.

G (not D): Before using Oracle Enterprise Manager Cloud Control 12c with Oracle Exadata, an Oracle Management Agent and Oracle Exadata plug-in must be installed on every Oracle Exadata database server (compute node). This agent monitors software targets, such as the database instances and Oracle Clusterware resources, on the database servers. The plug-in enables monitoring of other hardware components in Oracle Exadata, including the storage servers, switches, and power distribution units.

Question 17

The InfiniBand switches on your X5 Database Machine contain the software version as confirmed using the version command:
[root@exampsw –ib2 bin] # version SUN DCS 36p version: 1.3.3-2 Build time: Apr 4 2015 11:15:19 SP board info:
Manufacturing Date: 2014.05.05 Serial Number: “NCD3X0178” Hardware Revision: 0x0006 Firmware Revision: 0x0102 BIOS version: NOW1R112 BIOS date: 04/24/2014
Which two tools are useful for monitoring the InfiniBand switches for fan problems and by which users should they be run?

A. Run the env_test command on the switches after logging in as the ilom-admin user.
B. Run the getfanspeed command on the switches after logging in as root.
C. Run the env_test command on the switches after logging in as root.
D. Run the showtemps command on the switches after logging in as the ilom-admin user.

Correct Answer:CD
C: Login as root on IB switch and run,
# env_test
Example output include: Starting FAN test:
Fan 0 not present
WARNING Fan 1 running slow rpm 5450 limit 6440
WARNING Fan 2 running slow rpm 5341 limit 6440
WARNING Fan 3 running slow rpm 5341 limit 6440
D: The showtemps command displays internal temperatures for the switch.
The following example shows how to display switch temperatures with the showtemps command.
# showtemps
Back temperature 29
Front temperature 30
SP temperature 36
Switch temperature 52, maxtemperature 56 All temperatures OK

Question 18

Which two statements are true about backup performance when using Recovery Manager (RMAN) on an X5 Database Machine?

A. Backups are fast because the Infiniband network is faster than fiber channel storage, so RMAN read I/O operations are faster than in traditional storage networks.
B. Backups are fast, because physical I/Os operations are reduced by the use of the Storage Index by cellsrv.
C. Backups are fast, because data blocks are read from the Database Flash Cache.
D. Backups are fast, because all data blocks are read from the Exadata Smart Flash Cache.
E. For incremental backups using Block Change Tracking, cellsrv filters blocks and returns only those that have changed since the last backup.

Correct Answer:DE
D: The storage server software manages the flash cache and can recognize different types of I/O requests so that non-repeatable data access like RMAN backup I/O does not flush database blocks from the cache. It also prioritizes frequently accessed block types such as redo logs, control files, and index root blocks.
E: RMAN block change tracking allows incremental backups to run very quickly and efficiently. With block change tracking, only the areas of the database that have been modified since the last incremental backup or full backup are read from disk.

Question 19

Which two communication methods are used by which components in the Enterprise Manager architecture for a Database Machine?

A. SNMP traps for alerts are sent by the storage server ILOM directly to the Enterprise Manager agent.
B. SNMP traps for alerts are sent by the storage server ILOM to the storage server MS process.
C. SNMP traps for alerts are sent by the storage server MS process to the Enterprise Manager agent.
D. SNMP traps for alerts are sent by the storage server MS process to the storage server ILOM.
E. SNMP traps for alerts are sent by the storage server ILOM to the storage server RS process.

Correct Answer:BC

Question 20

Which two activities are supported on the storage servers in an Exadata X6 Database Machine?

A. Upgrading the Storage Server software package using RPM
B. Configuring secure shell user equivalency for the cellmonitor user
C. Installing an alternative package manager
D. Changing the root password
E. Upgrading a device driver for hard disks when inserting a replacement disk after a hard disk failure

Correct Answer:AC
