Question 1
CORRECT TEXT
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 SELINUX
Modify the state of selinux to Enforcing mode.
Use VIM /etc/selinux

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.

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 NFS service
Configure the NFS service on the system1, as required:
1. Share the directory /public in read only way, just can be accessed by systems in
domain11.example.com at the same time.
