EX300 Questions and Answers

Deploying your exam system: link to the iscsi target in the instructor.example.com and distinguish it well, then format as ext3 file system. You must be able to mount the file system of the iscsi target to the /mnt/iscsi directory in your own system and make this file system can automatically mount (permanently mount) after system restart.

Configure the kernel parameters: rhelblq=1, and it is requested that your kernel parameters can be verified through /proc/cmdline.

There were two systems:

• system1, main system on which most of the configuration take place
• system2, some configuration here

iSCSI Initiator

• The serverX.example.com provides an iscsi port (3260). Connect the disk with desktopX.example.com and configure filesystem with the following requirements.
• Create 800 MB partition on iSCSI block device and assign the filesystem as xfs
• Mount the volume under /mnt/initiator at the system boot time
• The filesystem should contain the copy of http://station.network0.example.com/pub/iscsi.txt
• The file should be owned by root with 0644 permission
• NOTE: the content of the file should not be modified

Virtual hosting.

• Setup a virtual host with an alternate document root.
• Extend your web to include a virtual for the site vhostsX.example.com">http://vhostsX.example.com
• Set the document root as /usr/local/vhosts
• Download station.network0.example.com/pub/rhce/vhost/html">http://station.network0.example.com/pub/rhce/vhost/html
• Rename it as index.html
• Place this document root of the virtual host
• Note: the other websites configures for your server must still accessible. vhosts.networkX.example.com is already provided by the name server on example.com

SSH configuration.

• Configure SSH access on your virtual hosts as follows.
• Clients within my22ilt.org should NOT have access to ssh on your systems

RHCE Test Configuration Instructions

Information for the two systems you will use in test is the following:

system1.group3.example.com: is one of the main sever. system2.group3.example.com: mainly used as a client.

Password for both of the two systems is atenorth

System’s IP is provided by DHCP, you can regard it as normal, or you can reset to Static IP in accordance with the following requirements:

system1.group3.example.com: 172.24.3.5

system2.group3.example.com: 172.24.3.10

The subnet mask is 255.255.255.0

Your system is a member of DNS domain group3.example.com. All systems in DNS domain group3.example.com are all in subnet 172.24.3.0/255.255.255.0, the same all systems in this subnet are also in group3.example.com, unless specialized, all network services required to be configured can be accessed by systems of domain group3.

host.group3.example.com provides a centralized authentication service domain

GROUP3.EXAMPLE.COM, both system1 and system2 have already been pre-configured to be the client for this domain, this domain provides the following user account:

Firewall is enabled by default, you can turn it off when deemed appropriate, other settings about firewall may be in separate requirements.

Your system will be restarted before scoring, so please ensure that all modifications and service configurations you made still can be operated after the restart without manual intervention, virtual machine instances of all examinations must be able to enter the correct multi-user level after restart without manual assistance, it will be scored zero if the test using virtual machine system cannot be restarted or be properly restarted.

Corresponding distribution packages for the testing using operating system Red Hat Enterprise Linux version can be found in the following link:

http://server1.group3.example.com/rhel

Part of the requirements include host security, ensure your host security limit does not prevent the request to allow the host and network, although you correctly configured the network service but would have to allow the host or network is blocked, this also does not score.

You will notice that some requirements which clearly do not allow services be accessed by service domain my133t.org, systems of this domain are in subnet 172.25.1.0/252.255.255.0, and systems of these subnets also belong to my 133t.org domain.

PS: Notice that some test questions may depend on other exam questions, for example, you might be asked to perform a series of restrictions on a user, but this user creation may be required in other questions. For convenient identification, each exam question has some radio buttons to help you identify which questions you have already completed or not completed. Certainly, you do not need to care these buttons if you don’t need them.

Configure a Database

Create a Maria DB database named Contacts on system1 and meet the following requirements at the same time:

• The database should contain the contents of the database replication, URL for copying files is:

http://rhgls.domain11.example.com/materials/users.mdb

• Database just can be accessed by localhost
• In addition to the root user, this database only can be searched by user Luigi, user’s password is redhat
• The password for root user is redhat, does not allow empty password

Give Full Permission to owner user and owner group member but no permission to others on /data.

Add a cron schedule to take full backup of /home on every day at 5:30 pm to /dev/st0 device.
