RedHat EX407 Practice Test Questions Answers

Install and configure ansible

User bob has been created on your control node. Give him the appropriate permissions on the control node. Install the necessary packages to run ansible on the control node.

Create a configuration file /home/bob/ansible/ansible.cfg to meet the following requirements:

• The roles path should include /home/bob/ansible/roles, as well as any other path that may be required for the course of the sample exam.

• The inventory file path is /home/bob/ansible/inventory.

• Ansible should be able to manage 10 hosts at a single time.

• Ansible should connect to all managed nodes using the bob user.

Create an inventory file for the following five nodes:

nodel.example.com

node2.example.com

node3.example.com

node4.example.com

node5.example.com

Configure these nodes to be in an inventory file where node1 is a member of group dev. nodc2 is a member of group test, nodc3 is a member of group proxy, nodc4 and node 5 are members of group prod. Also, prod is a member of group webservers.

control.realmX.example.com _ workstation.lab.example.com

node1.realmX.example.com _ servera.lab.example.com

node2.realmX.example.com _ serverb.lab.example.com

node3.realmX.example.com _ serverc.lab.example.com

node4.realmX.example.com _ serverd.lab.example.com

node5.realmX.example.com

- username:root, password:redhat

- username:admin, password:redhat

note1. don’t change ‘root’ or ‘admin’ password.

note2. no need to create ssh-keygen for access, its pre-defined

note3. SELinux is in enforcing mode and firewalld is disabled/stop on whole managed hosts.

===================================================================================

Create a role called apache in "/home/admin/ansible/roles" with the following

requirements:

--> The httpd package is installed, enabled on boot, and started.

--> The firewall is enabled and running with a rule to allow access to the web server.

--> template file index.html.j2 is used to create the file /var/www/html/index.html

with the output:

Welcome to HOSTNAME on IPADDRESS

--> Where HOSTNAME is the fqdn of the managed node and IPADDRESS is the IP-Address of

the managed node.

note: you have to create index.html.j2 file.

--> Create a playbook called httpd.yml that uses this role and the playbook runs on

hosts in the webservers host group.

===================================================================================

control.realmX.example.com _ workstation.lab.example.com

node1.realmX.example.com _ servera.lab.example.com

node2.realmX.example.com _ serverb.lab.example.com

node3.realmX.example.com _ serverc.lab.example.com

node4.realmX.example.com _ serverd.lab.example.com

node5.realmX.example.com

- username:root, password:redhat

- username:admin, password:redhat

note1. don’t change ‘root’ or ‘admin’ password.

note2. no need to create ssh-keygen for access, its pre-defined

note3. SELinux is in enforcing mode and firewalld is disabled/stop on whole managed hosts.

Create user accounts

------------------------

--> A list of users to be created can be found in the file called user_list.yml

which you should download from http://classroom.example.com/user_list.yml and

save to /home/admin/ansible/

--> Using the password vault created elsewhere in this exam, create a playbook called

create_user.yml

that creates user accounts as follows:

--> Users with a job description of developer should be:

--> created on managed nodes in the "dev" and "test" host groups assigned the

password from the "dev_pass"

variable and these user should be member of supplementary group "devops".

--> Users with a job description of manager should be:

--> created on managed nodes in the "prod" host group assigned the password from

the "mgr_pass" variable

and these user should be member of supplementary group "opsmgr"

--> Passwords should use the "SHA512" hash format. Your playbook should work using

the vault password file

created elsewhere in this exam.

while practising you to create these file hear. But in exam have to download as per

questation.

user_list.yml file consist:

---

user:

- name: user1

job: developer

- name: user2

job: manager

Create a file in /home/sandy/ansible/ called report.yml. Using this playbook, get a file called report.txt (make it look exactly as below). Copy this file over to all remote hosts at /root/report.txt. Then edit the lines in the file to provide the real information of the hosts. If a disk does not exist then write NONE.

In /home/sandy/ansible/ create a playbook called logvol.yml. In the play create a logical volume called Iv0 and make it of size 1500MiB on volume group vgO If there is not enough space in the volume group print a message "Not enough space for logical volume" and then make a 800MiB Iv0 instead. If the volume group still doesn't exist, create a message "Volume group doesn't exist" Create an xfs filesystem on all Iv0 logical volumes. Don't mount the logical volume.
