Which two statements are true concerning Oracle 12c Clusterware-managed application VIPs?
A. If an application sends messages to be displayed and sets the DISPLAY variable, then an application VIP is required.
B. An application VIP is created on the default network by the appvipcfg utility.
C. An application VIP is created on the interconnect network by the crsctl utility.
D. An application VIP can be created with the crsctl utility.
E. Application VIPs do not fail over to surviving cluster nodes when the node hosting the VIP fails.
Correct Answer: BD
Section: (none)
B: Oracle 11.2 introduced appvipcfg utility for creating VIPs. From the GRID_HOME/bin directory run the appvipcfg command to create the application VIP. Oracle Clusterware assigns this VIP to a physical server in the cluster and will migrate the VIP to a surviving node in the cluster in the event of a server failure.
D: While you can add a VIP in the same way that you can add any other resource that Oracle Clusterware manages, Oracle recommends using the script Grid_home/bin/appvipcfg to create or delete an application VIP. Incorrect Answers:
E: When a node dies in an Oracle RAC cluster, the Virtual IP (VIP) fails over to a different node. Upon node failure application VIP fails over to a surviving node along with the protected application. It is the Application VIP that is used for accessing the application, thus in case of failure the application will be highly.
Which three statements are true concerning node evictions and reboots performed by Oracle Clusterware 12c?
A. All node evictions require that the evicted node or nodes be rebooted.
B. A node whose performance is severely degraded can be evicted.
C. The OCSSD process may evict a node after an escalation request from a database instance LMON process.
D. The CSSDMONITOR process can request a node eviction.
E. The OCLSKD process is used for node eviction requests originating on the node to be evicted.
F. The reboot advisory broadcasts reboot decisions only over the interconnect.
Correct Answer: BDE
Section: (none)
D: The cssdagent and cssdmonitor provide the following services to guarantee data integrity: Monitors the CSS daemon; if the CSS daemon stops, then it shuts down the node
Monitors the node scheduling to verify that the node is not hung, and shuts down the node on recovery
from a hang.
Note If the Oracle Clusterware itself is working perfectly but one of the RAC instances is hanging , the database LMON process will request a member kill escalation and ask the CSS process to remove the hanging database instance from the
cluster.
On a Linux/Unix system CSS consists of ocssd.bin, cssdmonitor, and cssdagent.
E: Cluster kill daemon (oclskd) handles instance/node evictions requests that have been escalated to the Cluster Synchronization Service (CSS). Incorrect Answers:
C: Ocssd manages cluster node membership and runs as the oracle user; failure of this process results in a node restart.
Question 73:
Which three statements are true about Server Categorization in Oracle 12c Clusterware?
A. All server attributes that may be used to determine the server category are discovered automatically by Oracle Clusterware.
B. Different Hub nodes in a flex cluster may belong to separate administrator-defined categories.
C. All hub nodes in a flex cluster belong to the same Oracle-supplied category.
D. A server may be added to only one category using the crsctl utility.
E. All leaf nodes in a flex cluster belong to the same Oracle-supplied category.
F. All server attributes used for categorization are administrator modifiable.
Correct Answer: CEF
Section: (none)
CE: The SERVER_CATEGORY is the name of a registered server category, used as part of server categorization. Oracle Clusterware standard Clusters and Oracle Flex Clusters have default categories of hub and leaf.
F: Server Category Attributes You define servers into named categories, and assign attributes that define servers as members of that category. Some attributes that you can use to define members of a category describe the state conditions for the server, and others describe the physical characteristics of the server. You can also create your own characteristics to define servers as members of a particular category.
When using Oracle 12 Clusterware, which two actions are required to repair the ocr.loc file on host01 in a cluster having three other nodes called host02, host03, and host04?
A. Run ocr.config 璻epair on another node in the cluster to repair the ocr.loc file on host01
B. Stop the clusterware stack on host01 only.
C. Stop the clusterware stack on all cluster nodes.
D. Run ocrconfig 璻epair on host01.
E. Stop the clusterware stack on host01 and on the node used to issue the ocrconfig 璻epair command.
Correct Answer: BD
Section: (none)
B: You cannot repair the OCR configuration on a node on which the Oracle Cluster Ready Services daemon is running.
D: When you repair OCR on a stopped node using ocrconfig -repair, you must provide the same OCR file name (which should be case-sensitive) as the OCR file names on other nodes. Reference: https://docs.oracle.com/cd/E11882_01/rac.112/e41959/votocr.htm#CHDJJDEF
Question 75:
Which two types of IP address details are administered using the srvctl command for Oracle Clusterware 12c?
A. the Grid Naming Service (GNS) VIP
B. public IP addresses
C. High Available VIP (HAIP) addresses
D. Single Client Access Name (SCAN) VIPs
E. Storage Network IP addresses
Correct Answer: AD
Section: (none)
A: To convert a cluster that is not running GNS to a GNS server cluster, run the following command as root, providing a valid IP address and a domain:
# srvctl add gns -vip IP_address -domain domain
D: Example:
1.
Modify the VIP using a VIP name that resolves to IPv6 by running the following command as root:
# srvctl modify vip -node node_name -address vip_name -netnum network_number Do this once for each node.
2.
2. Modify the SCAN using a SCAN name that resolves to IPv6 by running the following command:
$ srvctl modify scan -scanname scan_name
Incorrect Answers:
C: The oifcfg command is used configure HAIP addresses. For example: oifcfg setif -global eth3/172.16.2.0:cluster_interconnect
Which statement is true concerning the installation of an Oracle Grid Infrastructure 12c patchset and its status during the installation?
A. Some grid infrastructure patchsets may not be installed in a rolling fashion.
B. They can be applied in-place.
C. When performing rolling patches, crsctl query crs softwareversion always displays the lowest version of the software running anywhere in the cluster
D. When performing rolling patches, the VIPs for the node being patched are relocated to another node.
Correct Answer: C
Section: (none)
To check the software versions on a single node. Software version is the lastest version installed in on an cluster.
You would use this option when you do the rolling upgrade.
Which three statements are true about Oracle Clusterware 12c Flex Cluster architecture?
A. Each leaf node must be connected to storage shared across all cluster nodes.
B. Hub nodes require direct access to the voting disks.
C. Each leaf node must be connected to storage shared across all leaf nodes.
D. Each hub node must be connected to storage shared across all hub nodes.
E. Hub nodes require direct access to the OCR file.
F. Leaf nodes require direct access to the voting disks.
Correct Answer: BED
Section: (none)
BE: In Oracle Flex Cluster, only Hub nodes will have direct access to the OCR/Voting disks.
D: The Leaf nodes are different from the Hub nodes. They don't need to have direct access to the underlying storage; rather they access the storage/data through Hub nodes. References: http://allthingsoracle.com/oracle-database-12c-new-features-part-3/

Which two utilities can be used to predict the consequences of a filesystem failure for the Oracle 12c Clusterware stack?
A. asmcmd
B. srvctl predict....
C. crsctl fail....
D. asmca
E. acfsutil
F. advmutil
Correct Answer: BE
Section: (none)
B: The srvctl predict filesystem command predicts the consequences of file system failure.
E: The acfsutil info fs command displays detailed Oracle ACFS file system information, such as: iscorrupt - 1 if the file system is corrupt, 0 if file system is not corrupt.
Incorrect Answers:
A: ASMCMD is a command-line utility that you can use to manage Oracle ASM instances, disk groups, file access control for disk groups, files and directories within disk groups, templates for disk groups, and volumes.
C: There is no crsctl fail command.
There is a crsctl eval fail resource command to predict the consequences of a resource, not the file system, failing.
D: Oracle ASM Configuration Assistant (ASMCA) supports installing and configuring Oracle ASM instances, disk groups, volumes, and Oracle Automatic Storage Management Cluster File System (Oracle ACFS). In addition, you can use the
ASMCA command-line interface as a non-GUI utility.
F: advmutil canonical displays the canonical name of the specified Oracle ADVM device name. dvmutil tune displays the value of a specific Oracle ADVM parameter or sets the value of a specific Oracle ADVM parameter.
advmutil volinfo displays information about Oracle ADVM volume devices.
