Oracle Database 12c: RAC and Grid Infrastructure Administration — Question 33
Examine the Data Guard configuration:
DGMGRL> show configuration verbose;
Configuration Animals -
Protection Mode: MaxPerformance -
Databases:
cats- Primary database
dogs-(*) Physical standby database
sheep- Physical standby database
(*) Fast-Start Failover target
Properties:
FastStartFailoverThreshold = 30 -
OperationTimeout = 30 -
TraceLevel = USER -
FastStartFailoverLagLimit = 30 -
CommunicationTimeout= 180 -
ObserverReconnect= 10 -
FastStartFailoverAutoReinstate= FALSE
FastStartFailoverPmyShutdown= TRUE
BystanderFollowRoleChange= none -
ObserverOverride = FALSE -
Fast-Start Failover: ENABLED -
Threshold: 30 seconds -
Target: dogs -
Observer: 015.example.com -
Lag Limit: 30 seconds -
Shutdown Primary: TRUE -
Auto-reinstate: FALSE -
Observer Reconnect: 10 seconds -
Observer Override: TRUE -
Configuration Status:
SUCCESS -
Which two are true?
Answer options
- A. The observer must run on host ol5.example.com and is currently not running.
- B. The observer will reinstate Sheep automatically after a failover, if required.
- C. The observer will mark another standby database as the failover target if the original failover target becomes unavailable.
- D. The observer will detect if the primary database is unable to accept new connections.
- E. The former primary database will not be reinstated automatically after a failover.
Correct answer: B, E
Explanation
Option B is correct because the configuration indicates that automatic reinstatement is not enabled, meaning the observer will not reinstate Sheep without manual intervention. Option E is correct as it aligns with the configuration that specifies 'FastStartFailoverAutoReinstate= FALSE', indicating the former primary will not be reinstated automatically. The other options do not accurately reflect the provided configuration details.
