Which two communication methods are used by which components in the Enterprise manager
Architecture for the Database Machine?
A.
SNMP traps for alerts are sent by the storage server ILOM to the storage serverMSprocess
B.
SNMP traps for alerts are sent by the storage serverMSprocess to the storage server ILOM
C.
SNMP traps for alerts are sent by the storage serverILOMto the Enterprise Manageragent.
D.
SNMP traps for alerts are sent by the storage serverMSprocess to the enterprise
Manageragent
E.
SNMP traps for alerts are sent by the storage server ILOM to the storage server RS process.
Explanation:
There are two types of server alerts that come from Oracle Exadata Storage Server:
* (A)For Integrated Lights Out Manager (ILOM)-monitored hardware components, ILOM
reports a failure or threshold exceeded condition as an SNMP trap, which is received by MS.
MS processes the trap, creates an alert for the storage server, and delivers the alert via SNMPto Oracle Enterprise Manager 12c.
* (D)For MS-monitored hardware and software components, MS processes a failure or threshold
exceeded condition for these components, creates an alert, and delivers the alert via SNMP to
Oracle Enterprise Manager Cloud Control 12c.

A & D
A is wrong. EM Agent runs remote ipmitool and SNMP calls to each node ILOM target
B is wrong. SNMP does not send from MS to ILOM
C is right. EM Agent runs remote ipmitool and SNMP calls to each node ILOM target
D is right. MS sends SNMP to OEM agent
E is wrong. SNMP does not send from ILOM to RS
So C.D. are correct
A is right. Storage Server ILOM send SNMP to MS
For compute node ILOM, EM Agent runs remote ipmitool and SNMP calls.
So A.D. are correct
A and D are correct as per below:
