Which three are true about Exadata storage server alerts?
A.
A threshold based alert gets cleared automatically when the measured value no longer violates
the threshold.
B.
A storage server alert is only ever issued as a warning or at a critical situation.
C.
Storage server alerts are all stateless alerts.
D.
Storage server alerts notifications may be sent using SNMP.
E.
Storage server alerts are all stateful alerts.
F.
Storage server alerts notifications may be sent using SMTP.
Explanation:
Incorrect:
Not C, Not E: there are both stateful and stateless alerts
a d f
warning, critical, clear, info for alert severity
A is right. The alert gets cleared automatically when no longer violates
B is wrong. Status and alerts are issued to OEM via SNMP
C is wrong. alerts can be stateless or stateful
D is right. alerts notification may be sent using SNMP or SMTP
E is wrong. alerts can be stateless or stateful
F is right. alerts notification may be sent using SNMP or SMTP
So A.D.F. are correct
I doubt about answer a, for the below reason:
Stateful alerts are automatically cleared on transition to normal.
Stateless alerts are never cleared unless you change the alert by setting the examineBy attribute.
I would rather go with answer B, for the below reason:
Although there are three types of storage alerts, informational, warning and critical, they are issued when threshold metrics reached either to warning or critical.
Answer D,F:
Exadata cell alerts can be delivered using SMTP or SNMP or both.
