• Question 43:

  How do you modify Kernel Parameters to meet the minimum requirements for Oracle RAC? (Select all that Apply)

  A. Pre-Oracle RAC 11g Release 2 manually changing the kernel Parameters is required to meet Oracle RAC minimum requirements.
  B. With Oracle Grid Infrastructure / Oracle RAC 11g Release 2 fixup-scripts (CVU generated) can be used to set the appropriate kernel Parameters.
  C. The Oracle Enterprise Manager can be used to modify kernel Parameters before the Installation of the Oracle RAC stack.
  D. You do not need to change any Kernel Parameters for an Oracle RAC installation.
  A. Pre-Oracle RAC 11g Release 2 manually changing the kernel Parameters is required to meet Oracle RAC minimum requirements.
  B. With Oracle Grid Infrastructure / Oracle RAC 11g Release 2 fixup-scripts (CVU generated) can be used to set the appropriate kernel Parameters.

  ---

  A: In Pre-Oracle RAC 11g Release 2 we did manually changed the kernel Parameters to meet Oracle RAC mini- mum requirements

  B: With Oracle Clusterware 11g release 2, Oracle Universal Installer (OUI) detects when the minimum require- ments for an installation are not met, and creates shell scripts, called fixup scripts, to finish incomplete system con- figuration steps. If OUI detects an incomplete task, then it generates fixup scripts (runfixup.sh). You can run the fixup script after you click the Fix and Check Again Button.

  You also can have CVU generate fixup scripts before installation. Reference: Installation Fixup Scripts

• Question 44:

  Identify the incorrect statement regarding private interconnect in an Oracle Clusterware and RAC environment.

  A. With Oracle RAC 11.2.0.2 and later versions, Redundant Interconnect Usage can be used instead of Network Interface Card (NIC) bonding.
  B. NIC bonding for the Oracle RAC interconnect is not required.
  C. If you use bonded NIC cards, they should be on the same subnet.
  D. If you use NIC cards, they must be on different subnets.
  C. If you use bonded NIC cards, they should be on the same subnet.

  ---

  You can bond separate interfaces to a common interface to provide redundancy, in case of a NIC failure, but Oracle recommends that you do not create separate interfaces for Oracle Clusterware and Oracle RAC. If you use more than one NIC for the private interconnect, then Oracle recommends that you use NIC bonding. Note that multiple private interfaces provide load balancing but not failover, unless bonded.

• Question 45:

  Where is the OCRCONFIG executable located on Oracle Database 11g Release 1?

  A. The ORACE_HOME directory
  B. The ORACLE_HOME/bin directory
  C. The ORACLE_HOME directory for grid infrastructure
  D. The crs_home/bin directory
  E. The usr/local/bin directory
  B. The ORACLE_HOME/bin directory

  ---

  The OCRCONFIG executable is located in the Grid_home/bin directory.

• Question 46:

  Which two options are true regarding Grid Naming Service (GNS)?

  A. GNS daemon runs only on one node in the cluster at a time
  B. GNS replaces DNS
  C. GNS replaces all VIPs
  D. GNS requires DHCP
  E. GNS is not managed by Clusterware
  A. GNS daemon runs only on one node in the cluster at a time
  D. GNS requires DHCP

  ---

  A: Oracle Clusterware Daemon (CRSD)

  CRS daemon (Oracle Cluster Ready Services Daemon) internode connection. The port number is assigned automatically during installation. You cannot view or modify it afterward. This port is used exclusively with the cluster interconnect.

  D: To set up an Oracle 11g R2 RAC installation using Oracle Grid Naming Services (GNS) the following requirements need to be met:

  *

  At least two interfaces configured on each node, one for the private IP address and one for the public IP address.

  *

  A Domain Naming Server (DNS) running in the network for the address resolution of the GNS virtual IP address and hostname.

  *

  The DNS entry to configure the GNS sub-domain delegation

  *

  A DHCP server running on the same public network as your Oracle RAC cluster.

  Incorrect:

  Within the subdomain, the GNS uses multicast Domain Name Service (mDNS) (not B), included with Oracle Clusterware (not E), to enable the cluster to map host names and IP addresses dynamically as nodes are added and removed from

  the cluster, without requiring additional host configuration in the DNS.

• Question 47:

  You want to stop a CRSCTL command that is active. How should you do this?

  A. With the abort command
  B. With CTRL-C
  C. With CTRL-X
  D. With CTRL-A
  E. With CTRL-ALT-DEL
  B. With CTRL-C

  ---

  Stopping Active SRVCTL Commands

  Although you may be able to cancel running SRVCTL commands by pressing the Control-C keys, you may corrupt your configuration data by doing this.

  You are strongly advised not to attempt to terminate SRVCTL in this manner.

• Question 48:

  What command would you use to write- the OCR content from the subtree of the key SYSTEM to stdout?

  A. ocrdump SYSTEM stdout
  B. ocrdump stdout SYSTEM
  C. ocrdump stdout keyname SYSTEM
  D. ocrdump stdout -xml
  C. ocrdump stdout keyname SYSTEM

  ---

  Run the ocrdump command with the following syntax where filename is the name of a target file to which you want Oracle Database to write the OCR output and where keyname is the name of a key from which you want Oracle Database to

  write OCR subtree content:

  ocrdump [file_name|-stdout] [-backupfile backup_file_name] [-keyname keyname] [-xml] [- noheader]

  Reference: OCRDUMP Utility Syntax and Options

• Question 49:

  List the syntax supported by the Cluster Verification Utility (CVU). (select all that apply)

  A. comp - To show valid components with description
  B. stage - To list pre and post checks of stages
  C. asm - To list valid disks available
  D. dbstat - To list number of instances available online
  A. comp - To show valid components with description
  B. stage - To list pre and post checks of stages

  ---

  A: To verify the minimal system requirements on the nodes prior to installing Oracle Clusterware or Oracle RAC, use the sys component verification command as follows:

  cluvfy comp sys [ -n node_list ] -p { crs | database } } [-r { 10gR1 | 10gR2 | 11gR1} ] [ -osdba osdba_group ] [ -orainv orainventory_group ] [-verbose]

  B: To verify whether your system meets all of the criteria for an Oracle Clusterware installation, use the - pre crsinst command for the Oracle Clusterware installation stage as follows:

  cluvfy stage -pre crsinst -n node_list

  [ -c ocr_location ] [-r { 10gR1 | 10gR2 | 11gR1} ][ -q voting_disk ] [ -osdba osdba_group ] [ -orainv orainventory_group ] [-verbose]

• Question 50:

  Which two actions do you need to take in order to start up Oracle Grid Infrastructure automatically on boot?

  A. If Oracle Grid Infrastructure was disabled on a node, use "crsctl enable crs" to enable the automatic startup.
  B. Add the daemons to the system startup list.
  C. Nothing. By default, Oracle Grid Infrastructure is set up to start automatically on server boot.
  D. You must start clusterware daemons with individual commands in a batch file.
  A. If Oracle Grid Infrastructure was disabled on a node, use "crsctl enable crs" to enable the automatic startup.
  C. Nothing. By default, Oracle Grid Infrastructure is set up to start automatically on server boot.

  ---

  We can use crsctl commands as follows to enable and disable the startup of the Oracle Clusterware daemons. Run the following command to enable startup for all of the Oracle Clusterware daemons:

  crsctl enable crs

  Run the following command to disable the startup of all of the Oracle Clusterware daemons:

  crsctl disable crs
