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 the 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:[2021.3] lead4pass ex300 practice test q1

The firewall is enabled by default, you can turn it off when deemed appropriate, other settings about the firewall may be in

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 the 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 to 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 about these buttons if you don\\’t need them.
