B. It is where the Cluster Health Monitor places data.
C. It is created during a ''Typical" installation.
D. It is stored in the ASM disk group that is used as a Fast Recovery Area.
Which three statements about Oracle RAC background processes are correct?
A. ACMS (Atomic Controlfile to Memory Service) is an agent that contributes to ensuring that a distributed SGA memory update is either globally committed on success or globally aborted if a failure occurs
B. GTXO-j (Global Transaction Process) controls the flow of messages to remote instances, manages global data block access, and transmits block images between the buffer caches or different instances
C. LMON (Global Enqueue Service Monitor) monitors global enqueues and resources across the cluster and performs global enqueue recovery operations
D. LMD (Global Enqueue Service Daemon) manages incoming remote resource requests within each instance
E. LMS (Global Cache Service Process) manages non-Cache Fusion resource requests such as library and row cache requests
F. LCKO (Instance Enqueue Process) manages background slave process creation and communication on remote instances
You want to change an existing Oracle Clusterware standard Cluster to an Oracle Flex Cluster There is Grid Naming Service (GNS) and Flex ASM configured right now. In what order do you need to take the following steps?
1.
Stop Oracle Clusterware
2.
Determine the current mode of the cluster
3.
Ensure that the GNS is configured with a fixed VIP.
4.
Change the mode of the cluster to be an Oracle Flex Cluster.
5.
Use the Oracle Automatic Storage Management Configuration Assistant (ASMCA) to enable Oracle Flex ASM in the cluster
6.
Start Oracle Clusterware
A. 1, 2, 3, 5, 4, 6
B. 2, 3, 5, 4, 1, 6
C. 1, 2, 3, 4, 5, 6
D. 2, 3, 4, 5, 1, 6
The customer is still not convinced about the advantages of using node VIPs. Which is the most important point that will convince him about why VIPs are used in Oracle RAC 12cR1 environments?
A. It is very convenient as whenever a node/interface/network related to the node VIP fails, the VIP can fail to another node and the failed over VIP can start accepting connections from the new node avoiding connection failures
B. This is needed as whenever a node/interface/network related to the node VIP fails, clients that attempt to connect to the VIP address receive a rapid connection-refused error instead of waiting for TCP connect timeout messages. This helps for a quicker failure detection and resolution
C. It is needed as whenever the node/interface/network related to the VIP fails, nothing happens and node VIP never fails to any other node and stays stable
D. Configuring VIP is optional and not needed in an Oracle RAC 12cR1 configuration.
The DISK_REPAIR_TIME attribute has expired after a transient disk error. What happens next?
A. Nothing, it was only a warning. All the disks are OK
B. This means that the disk is repaired and is put back in the ASM disk group.
C. Oracle ASM drops the disk.
D. This means that Oracle will use ASM Fast Mirror Resync to sync the rest of the disks.
You are installing Oracle Grid Infrastructure with Oracle Universal Installer (OUI). Your goal is a cluster that contains both database nodes and application nodes.

B. Choice ''Yes" in the Grid Infrastructure Management Repository Option step
C. Choice "Configure e Flex cluster" in the Cluster Type selection step
D. Choice "Use Standard ASM for storage" in the Storage Option step
E. Choice "Use Oracle Flex ASM for storage" in the Storage Option step
F. Choice "Configure GNS" in the Grid Plug and Play step
