You are doing a RAC implementation for a customer. Your customer states that they have the hardware to install additional network adapters on each RAC node. ldentify three reasons for which they might need additional adapters

A. Each server has at least two network adapters

B. Each server was accidentally ordered with only one network adapter

C. Each server is using network-attached storage on one or two of their adapters

D. They want to use the Redundant Interconnect Usage feature

E. Each server has two network adapters and RAC requires at least three

You are beginning the process of creating an Oracle ACFS volume. Which command creates an Oracle ACFS volume?

A. asmcmd[ + ) > volcreate -G data -s 5G volume1

B. asmcmd [ + ] > vol create -G data -s 5G volume1

C. asmcmd [ + ] > alter diskgroup DATA create volume1 size 5G;

D. asmcmd [ + ] > createvol -G data -a 5G volume1

Which statement about the server Flex ASM is incorrect?

A. Flex ASM requires an ASM instance on each cluster node running an Oracle Database instance

B. Flex ASM allows ASM clients to remotely connect to ASM over a network.

C. With Flex ASM ,a small pool of ASM instances can be used to serve a larger pool of database servers.

D. When an ASM instance fails, the database clients and ASM cluster file systems can reconnect another ASM instance.

Which statement accurately describes the benefit of the policy-managed database feature with Oracle RAC 12cR1?

A. It protects against cascade failures due to network usage. It migrates workload isolation to specific pools. Less important workloads shut down immediately.

B. It protects against cascade failures due to load. It ensures that workload isolation is balanced between pools. Less important workloads start transactionally

C. It protects against cascade failures due to load. It ensures workload isolation between pools. Less important workloads shut down transactionally

D. It protects against cascade failures due to load. It ensures workload isolation between pools. Less important workloads shut down and start uniformly.

E. It protects against cascade failures due to load. It ensures workloads are not isolated between pools. Less important workloads shut down transactionally.

You are building a new 12c cluster to accommodate the upcoming projects. You are currently working with the network admin team to define the requirements needed. Currently, the network team would like to get cleared on the protocols being used by the various network interface needed. Which three statements about Clusterware communication are correct?

A. For the public network, each network adapter must support TCP/IP. This requirement holds true for both Microsoft Windows and Linux/Unix environments

B. For the private network, the interface must support the user datagram protocol (UDP) using high speed network adapters and switches that support TCP/IP. This holds true in the Linux/Unix environment.

C. For the public network, each network adapter needs to support only UDP, which provides low latency. This requirement holds true for both Microsoft Windows and Linux/Unix environments

D. For the private network, the network adapters must use high-speed network adapters and switches that support TCP/IP. This requirement holds true in the Microsoft Windows environment

E. There is no mandatory requirement for the protocol being supported for both private and public interfaces. Oracle RAC and Clusterware aulomatically detect and support any current standard industry protocol

Identify the root cause of Enqueue: CF - Contention in this scenario.

A. Root cause is a stalled LGWR due to LGWR waits Enqueue: CF contention is caused by the db file sequential reads

B. Root cause is blocked LGWR due to LGWR waits LGWR waits ENQUEUE: CF contention is a symptom of the db file scattered reads and excessive ITL waits

C. Root cause is a blocked LGWR due to LGWR waits for enqueue: CF - contention, which may be held by another background process. Background process may hold a CF enqueue while updating the control file

D. Root cause is blocked LGWR due to SCAN_LISTENERS(s) dropping client connections during DoS event

The exhibit describes an Oracle Clusterware startup.

Which item is missing?

A. ohasd

B. ocssd

C. crsd

D. octssd

E. osysmond

F. oraagent

During the installation of Oracle Grid Infrastructure 12cR1, you decide to configure the Grid Infrastructure Management Repository. Where will the repository be stored?

A. In its own single instance Oracle Database 12cR1 database and managed as a failover database

B. In the first RAC database created on the cluster

C. In its own RAC 12cR1 database with load balancing enabled

D. On a node outside the cluster to guard against cluster failure

E. Within the Grid Infrastructure home as a file-based repository

Which statement about the AU_SIZE disk group attribute is incorrect?

A. It specifies the size of the allocation unit for a disk group.

B. It can be changed at any time for any disk group.

C. You can view the value of this attribute in the ALLOCATION_UNIT_SIZE column of the V$ASM_DISKGROUP view

D. The default size is 1 MB.
