Question 55/86
Which three statements are true about Oracle Clusterware components, architecture, and behavior?
Correct Answer: C,D,F
Explanation/Reference:
Explanation:
F: To activate CTSS in your cluster, you must stop and deconfigure the vendor time synchronization service on all nodes in the cluster. CTSS detects when this happens and assumes time management for the cluster.
For example, to deconfigure NTP, you must remove or rename the ntp.conf file.
Incorrect Answers:
A: The CRS daemon (crsd) manages cluster resources based on the configuration information that is stored in OCR, not the OLR, for each resource.
B: You must update OCR through supported utilities such as Oracle Enterprise Manager, the Oracle Clusterware Control Utility (CRSCTL), the Server Control Utility (SRVCTL), the OCR configuration utility (OCRCONFIG), or the Database Configuration Assistant (DBCA)
E: Please refer to the cluster startup picture below.
