A. To enable Dynamic Service Fallback, you should specify the level of performance of a preferred instance for a service to be relocated to an available instance by setting the -fallback attribute of a service to "Low, Medium, or High".

B. Dynamic Service Fallback allows a service to fall back to a preferred instance when it becomes available after it was failed over to an available instance.

C. Dynamic Service Fallback allows a service to relocate to an available instance when the service is stopped on a preferred instance.

D. Dynamic Service Fallback allows a service to fall back to a preferred instance when the available instance performance falls below a specified threshold after it was failed over to an available instance.

A. Using the rconfig utility to create a template from the single-instance database and then using dbca to create a RAC database on the cluster using that template

B. Using the rconfig utility to migrate the database to shared storage and then using dbca to start one or more RAC database instances on the cluster

C. Using dbca to create a template from the single-instance database and then to create a RAC database on the cluster using that template

D. Using dbca to migrate the database to shared storage and then to start one or more RAC database instances on the cluster

A. You must create a Grid Management Repository database.

B. You must enable the Name Server Cache Daemon

C. A DHCP service on the public network for the cluster is required to allocate virtual IP addresses as required by the cluster.

D. A DHCP service on the private network for the cluster is required to allocate virtual IP addresses for HAIP.

E. Each cluster node must have at least two network interface cards.

F. DNS must be configured to delegate name resolution for the cluster subdomain to the cluster.

A. Hardware-based mirroring combined with ASM mirroring guarantees optimal performance.

B. Data files, redo logs, and RMAN backup pieces must be stored in different ASM disk groups for optimal performance.

C. All ASM Disks belonging to a disk group should be of the same size for optimal performance.

D. All ASM Disks belonging to a disk group should have the same hardware specifications and storage attributes for optimal performance.

E. To improve performance a database must have two disk groups; one for data and one for the fast recovery area.

A. Create the current yr directory in the +data disk group.

B. lAdd the DATAFILE '/CURRENT YR/sales.dbf clause to the command.

C. Add the autoextend on clause to the command.

D. Add the DATAFILE '+DATA/CURRENT YR/sales.dbf clause to the command.

E. Create the current yr directory in the root directory (+).

A. In client-side load balancing, the SCAN listener uses the Load Balancing Advisory to direct a connection request to the least loaded instance hosting the service.

B. Client-side connect time load balancing is done at the time of the initial connection attempt to the database service.

C. Client-side connect time load balancing works only if it uses a tnsnames entry specifying load BALANCE=yes.

D. Server-side connect time load balancing is done at the time of the initial connection attempt to the database service.

E. Server-side load balancing connections are always distributed across instances based on the fastest response time for the service.

A. An application VIP can be created with the crsccl utility.

B. If an application sends messages to be displayed and sets the display variable, then an application VIP is required.

C. An application VIP is created on the interconnect network by the crsccl utility.

D. Application VIPs do not fail over to surviving cluster nodes when the node hosting the VIP fails.

E. An application VIP is created on the default network by the appvipcfg utility.

A. It can contain ASM Dynamic Volume Manager (ADVM) volumes.

B. The ASM compatible attributes can be changed to 12. l for this disk group.

C. Each disk in each of the three fail groups is a mirror of the corresponding disk of the other two failure groups.

D. Any database instance with the COMPATIBLE parameter set to 12.2 or later can access it.

E. Files created in this disk group always have two copies for each allocation unit: one primary and one secondary.
