質問 2：
As part of the preinstatlation process for adding two new nodes to your four-node UNIX cluster, you are in discussions with the OS administrators about the operating system Installation and setup for the two new nodes called RACNODE5 and RACNODE6.
The nodes have already been connected to the network infrastructure and the administrators are ready for the OS installation. Which two methods fulfill the installation requirements?
A. Install a new image of the OS, then configure SSH for the root user.
B. Install a cloned image of the OS that at least matches the existing node images for drivers, patches, and updates.
C. Install a new image of the OS that at least matches the existing node Images for drivers.
D. Install a new image of the OS, and create the necessary OS users and groups with any user and group IDs.
E. Install a new image of the OS, that at least matches an existing node for drivers, patches, and updates, and create the necessary OS users and groups with user and group IDs matching those on the existing nodes.

質問 4：
You are ready to add two new nodes called RACNODE5 and RACNODE6 to your existing four-node cluster using addNode.sh
You have run cluvfy -peer to check the new nodes against a reference node.
When you originally created the cluster, the network administrators chose to statically define the scan vip addresses in the corporate DNS server, and you installed the Oracle Grid Infrastructure without using GNS.
What is the correct way to silently add the nodes? r
A. CLUSTER_NEW_NODES= {"RACNODE5, RACNODE6")
B. addNode. sh -silent "CLUSTER_NEW_NODES= { RACNODES, RACNODE6 } " "CLUSTER_NEW_VlRTUAL_HOSTNAMES= RACNODE5-VIP, RACNODE6-VI P > "
C. addNode . sh -silent "CLUSTER_NEW_VIRTUAL_HOSTNAMES=<(RACNODES -VI P, RACNODE6-VIP) "
D. addNode.sh -silent -responseFile mynewnodes . txt With the response file containing only CLUSTER NEW VIRTUAL HOSTNAMES= { " RACNODE3-VI P , RACNODE4 -VI P >
E. addNode . sh -silent "CLUSTER_NEW_nodes={ RACNODE5, RACNODEg > "
F. addNode.sh -silent -responseFile mynewnodea . txt With the response file containing only

質問 5：
Your Apache-based application resource called MyApp has a VIP application resource definition and an application resource definition.
The application is administrator managed and is currently active on nodeRACNODE3.
You want to move it to host RACNODE4, which is one of the HOSTING_MEMBERS in the resource definition.
What is the most efficient method to move the application and the VIP?
A. Run crsctl stop resource MyApp -n RACNODE3 -f followed by crsctl relocate resource MyApp -n RACNODE4.
B. Run crsctl relocate resource MyApp -n RACNODE4.
C. Run crsctl relocate resource MyApp - n RACNODE4 - f.
D. Run crsctl stop resource MyApp -n RACNODE3 -f followed by crsctl start MyApp -n RACNODE4 -f.

質問 6：
Which two statements are true regarding the Average Active Sessions chart on the performance page
A. It shows active aggregate wait class statistics across all the instances In the cluster database.
B. If the Average Active Sessions chart displays a large number of sessions waiting, indicating internal contention, but the throughput is high, then the situation may be acceptable.
C. If the Average Active Sessions chart displays a large number of sessions waiting, indicating internal contention, but the throughput is low, then the CPU needs to be upgraded
D. It shows active aggregate wait class per instance for all the instances In the cluster database.

A. /sbin/acfsutil size 20G /u01/app/oracle/afsmounts/vol1
B. None, an ACFS file system cannot be resized.
C. fsadm /u0l/app/orlacle/afsmounts/vol1 20G
D. ASMCMD [+] > volsize -G data -s 20G VOL1
E. SQL> ALTER DISKGROUP data RESIZE VOLUME vol1 SIZE 20G;
