What are the two benefits of configuring network interface bonding?
aggregating two or more Network Interfaces (NICs) toactas one logical interface
creating a static address that is bound to one NIC
providing either failover or load-balancing to two or more Network Interfaces (NICs)
binding a network interface to the embedded firewall (IPTables) for port filtering
Network bonding refers to the combination of network interfaces on one host for redundancy and/or increased throughput.

Which option determines whether a system users NIS, local files, DNS, or a combination as the source of information, and also order of the source?
The Name Service Switch (NSS) configuration file, /etc/nsswitch.conf, is used by the GNU C Library to determine the sources from which to obtain name-service information in a range of categories, and in what order. Each category of information is identified by a database name.
The file is plain ASCII text, with columns separated by spaces or tab characters. The first column specifies the database name. The remaining columns describe the order of sources to query and a limited set of actions that can be performed by lookup result.
Not A: In most Unix-like operating systems and others that implement the BIND Domain Name
System (DNS) resolver library, the resolv.conf configuration file contains information that
Not D:/etc/yp.conf - NIS binding configuration file
Which three things does oracle-edbms-server-11gR2-preinstall RPM package do to simplify the installation of Oracle Database on Oracle Linux 6 systems?
Downloads and installs various software packages and specific versions needed for Oracle database installation
Downloads and installs packages required for Oracle Database installation, runs the runInstaller utility to install the database, and then starts the database
Creates the Oracle user and the oinstall and dba groups, which are the default user and groups used during Oracle database installation
Modifies and sets kernel parameters in /etc/sysctl.conf and sets shell resource limits in /etc/security/limits.conf based on the Oracle Database Server installation requirements
Checks whether all packages are installed to support RDBMS and then calls the Oracle Universal Installer utility to install RDBMS and then calls the Oracle Universal Installer utility to install RDBMS
In order to install the Oracle Database 11g R2 on Oracle Linux 6, your system needs to meet a few prerequisites, as outlined in the Linux Installation Guides. Using the Oracle RDBMS Server 11gR2 Pre-install RPM, you can complete most of the pre-installation configuration tasks.
(A)Causes the download and installation of various software packages and specific versions needed for database installation, with package dependencies resolved via yum
(C)Creates the user oracle and the groups oinstall and dba, which are the defaults used during database installation
(D)Modifies kernel parameters in /etc/sysctl.conf to change settings for shared memory, semaphores, the maximum number of file descriptors, and so on
(D)Sets hard and soft shell resource limits in /etc/security/limits.conf, such as the number of open files, the number of processes, and stack size to the minimum required based on the Oracle Database 11g Release 2 Server installation requirements
*Sets numa=off in the kernel boot parameters for x86_64 machines
You found a message on a public discussion forum mentioning a Vulnerability (for example, CVE- 2006-5794), which could affect some versions of OpenSSH in Linux distribution. Identify the command that would allow you to see whether this CVE has been applied.
rpm –q – – changelogopenssh| grep 5794
yum listcvew openssh
rpm -qa | grep openssh | grep 5794
yum sec-list cves
*The command rpm -q --changelog rpm displays a detailed list of information (updates, configuration, modifications, etc.) about a specific package. This example shows information about the package rpm. However, only the last five change entries in the RPM database arelisted. All entries (dating back the last two years) are included in the package itself. This query only works if CD 1 is mounted at /media/cdrom: rpm -qp --changelog /media/cdrom/suse/i586/rpm-3*.rpm
*Is the patch RPM suitable for my system?
To check this, first query the installed version of the package. For pine, this can be done with
rpm -q pine pine-4.44-188 Incorrect:
*qa stands for "Query All"
Assuming you are attempting to find out if you have the Very Secure FTP Daemon installed, you want:
rpm -qa | grep vsftp
rpm -qa will show you all installed RPMs, piping it through grep will limit the list to RPMs containing the string "vsftp".
Which two conditions will cause OCFS2 to evict a node?
When a node no longer responds to network heartbeat signals from other members of the cluster
When storage array is at 90% capacity
When access to storage is lost
When a node is running at 90% utilization
A:How does the disk heartbeat work?
Every node writes every two secs to its block in the heartbeat system file. The block offset is equal to its global node number. So node 0 writes to the first block, node 1 to the second, etc. All the nodes also read the heartbeat sysfile every two secs. As long as the timestamp is changing, that node is deemed alive.
What types of packages are contained in the Oracle Public YUM server?
Base releases of Oracle and RedHat Linux distributions
Base releases of Oracle Linux and extra/updates for Oracle Linux

You may be prompted to confirm the import of the Oracle OSS Group GPG key.
A system administrator wants to enable packet without making the changes permanent. What command would he use to complete this action?
Echo 1> /proc/sys/net/ip_forward/
Echo 1> /proc/sys/net/ipv4_ip_forward
Echo 1 > /etc/sysconfig/sys/net/ipv4/ip_forward
Echo 0 > /proc/sys/net/ipv4/ip_forward
The '1' in "/proc/sys/net/ipv4/ip_forward" enables IP forwarding. A '0' signifies IP forwarding is disabled.

Consider taking this exam if you work for an OPN company or want to test the waters surrounding Oracle’s Linux distribution.
">1Z0-460: Oracle Linux 6 Implementation Essentials is the only exam required to become an Oracle Linux 6 Certified Implementation Specialist and there is no training requirement for this track. Oracle’s specialist certifications are of particular interest to companies that are in the Oracle Partner Network (OPN). The primary purpose of specialist certifications is to keep Oracle partners up to date with the latest versions of Oracle’s software and hardware. These companies gain advantages in their relationship with Oracle for having employees that hold specialist certifications.
That said, anyone can take the exam and earn the certification without being an employee of an OPN company. In fact, earning one or more of these certifications can make your resume more interesting to an Oracle partner. An OPN company that hires an Oracle professional with one or more of these specializations will immediately boost their numbers.
For anyone that has spent time performing Linux system administration tasks, the majority of the material on this exam is going to be familiar. Most of the commands and utilities covered would fit right in on a generic Linux certification exam such as those from CompTIA or LPI. Because Oracle Linux is derived from Red Hat Enterprise Linux, a fair amount of the exam refers to utilities that are in that distribution. Only about a fifth of the topics are about information that is completely specific to Oracle Linux.
While I have taken OCA, OCP, and OCE exams in the past, this is the first specialist certification I have taken. As such, I was not really sure going in what level of difficulty to expect. Given the fact that it is called an ‘essentials’ exam, I was expecting something at the OCA level or possibly even lower. The morning of the exam was a rude awakening. I would have to say this was somewhere just below the level of difficulty I’d expect for an OCP exam. I passed, but it was not nearly the walk in the park that I was expecting. While ">1Z0-460 does not get into advanced Linux topics, there were questions that required more detailed knowledge than I was expecting. Many of the questions asked were about things I do not normally memorize. After all, the ‘man’ command is always available in Linux. Unfortunately, that is not something that is available when sitting in the testing center trying to remember the letter for the option that performs a given function.
The Oracle Linux 6 Implementation Essentials exam topics cover the following areas:
The exam has 79 topics overall and 71 questions, so each should generate about one question on the exam. With two hours for the exam, I felt no time crunch at all. I finished with plenty of time to spare even after going back to take a second look at several questions I was unsure of. The exam I took had only a handful of questions that contained exhibits.
The information you need to study for the exam is split among numerous sources. The following five manuals contain the vast majority of technical information covered by the exam:
The exam does have a few topics that are outside those manuals. Some of the topics are about support websites or the advantages of various aspects of Oracle Linux 6. I used various resources on the Web to prepare for these. The Oracle Certification Prep website listed in the ’s box contains an exam details page for ">1Z0-460 with links to all of the applicable documentation. It also contains links to articles on various websites relevant to the exam.
If you have some experience working with Linux, simply reading up on the topics associated with the exam may be sufficient preparation for it. However, if you have never worked with Linux before, or have done so only in passing, then you really need to take the time to set up a server and practice with the operating system while you are studying the material. Reading documents may allow you to memorize facts about Oracle Linux 6, but it will not provide you with a means to apply that knowledge – either on the test or in real life. Good luck on the exam.

For Oracle employees and authorized partners only. Do not distribute to third parties. 2013 Oracle Corporation Page 75 of 99 OL 6- Lab 07 There are three common ways of configuring the kdump service: When FirstBoot tool is run after initial installation Using the Kernel Dump Configuration graphical utility Manually using command line option – ‘ system-config-kdump ’ Since we already have a running instance of Oracle Linux 6.3, we will not look at FirstBoot tool configuration. But you can refer to the screen shots in the Install lab that show the FirstBoot tool screens including the Kdump configuration screen. Before we look at configuring the kdump service, make sure you have the ‘ kexec- tools ’ package installed as this is needed for kdump configuration. If you do not have the ‘ kexec-tools ’ package installed, you should install it first using the ‘yum install kexec - tools’ command. Note: The ‘ diskdump ’ service sets up the kernel to save a memory image to the specified partition at the time of system panic etc. The ‘ diskdumputils ’ package for ‘ diskdump ’ was used in older versions of OracleRedHat Linux and that package has been obsoleted by ‘ kexec-tools ’ package. Kdump Configuration using Graphical User Interface: You can launch the GUI utility from the System -> Administration -> Kernel crash dumps option on your Oracle Linux 6.3 assuming that you have the Desktop GUI packages installed on your system. We installed the Desktop packages as part of Install lab of the boot camp.
OL 6 System Monitoring - Lab 7 For Oracle employees and authorized partners only. Do not distribute to third parties. 2013 Oracle Corporation Page 76 of 99 OL 6- Lab 07 Clicking the Kernel crash dumps menu option as shown above will launch the kdump configuration graphical utility. In the example below, it shows that kdump is not enabled. Click the ‘ Enable ’ button to enable the kdump service. Remember to click ‘ Apply ’ after enabling the kdump service. You should see the following screen if kdump is already enabled. If you see an error stating " Starting kdump:[FAILED]” , then you may have to reboot your system. This is because when you enable kdump it has to create the kdump initial ramdisk and a reboot can create the kdump initial ramdisk. Verify after reboot and confirm by running the tool again that the kdump service has been enabled.
