• B. Leaf servers are standard as in previousversions.
• C. Hub and Leaf topologies allow tightly and loosely coupled server membership
• D. Hub servers do not support Oracle ASM.
• E. Leaf servers arelight-weight, no shared storage, no peer-to-peer communication and dedicatedtoapplication service.
• F. Oracle Flex Cluster 12cR1 supports bare metal and OVM serversincommon cluster

A node ina four-node cluster encounters corruption on the OLR and must be restored from backups taken using clusterware utilities.Identify the option that shows the correct OLR restore commands.

Which three statements accurately describe the components of the Cluster Ready Services Technology Stack?

• A. Event Management (EVM). Provides time managementinacluster for Orade Clusterware
• B. Cluster Time Synchronization Service (CTSS): A background process that publishes events that Oracle Clusterware creates.
• C. Cluster Ready Services(CRS):Aspecialized oraagent process that helps CRSD manage resources owned by rootsuch as the network, and theGrid virtual IP address
• D. Grid Naming Service (GNS):Handles requests sent by external DNS servers, performing name resolution fornames defined by the cluster.
• E. Oracle Agent (oraagent): This process was known as RACG in Oracle Clusterware 11gR1 (11.1).
• F. Cluster Synchronization Services (CSS):Manages the cluster configuration by controlling which nodes are members of the cluster and by notifying members when a node joins or leaves the cluster

You have completed a rolling conversion fromDNS to GNScluster resolution from the database andcluster resources end.The remaining are the configuration changes to be done from theclient side.
Which two items need to betaken into account to achieve a successful connection?

• A. For each client using VIP names, change the VIP name on eachclient sothat they use the same server VIP name, but with the domain namein thedomain delegated to GNS.
• B. There is no need to change anything in client configuration as the combination of TAF and ONSwillautomatically take care of reaching the correct nodes
• C. For each client using a SCAN, change the SCAN theclient uses so that theclient uses the SCAN in the domain delegated to GNS
• D. All the nodes in the cluster need to be bounced oneafter the otherinorder for the changes to be completed as it is not possible to do it online
