Free RedHat EX407 Practice Exam with Questions & Answers

Using the Simulation Program, perform the following tasks:

Static Inventories Task:

1. Add a new group to your default ansible host file. call the group [ec2]

2. Add a new host to the new group you created.

3. Add a variable to a new host entry in the /etc/ansible/hosts file. Add the following. localhost http_port=80 maxRequestsPerChild=808

4. Check to see if maxRequestsPerChild is pulled out with an ad-hoc command.

5. Create a local host file and put a target group and then a host into it. Then ping it with an ad-hoc command.

Create a playbook called hwreport.yml that produces an output file called /root/

hwreport.txt on all managed nodes with the following information:

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

--> Inventory host name

--> Total memory in MB

--> BIOS version

--> Size of disk device vda

--> Size of disk device vdb

Each line of the output file contains a single key-value pair.

* Your playbook should:

--> Download the file hwreport.empty from the URL http://classroom.example.com/

hwreport.empty and

save it as /root/hwreport.txt

--> Modify with the correct values.

note: If a hardware item does not exist, the associated value should be set to NONE

Use Ansible Galaxy with a requirements file called /home/admin/ansible/roles/

install.yml to download and install roles to /home/admin/ansible/roles from the

following URLs:

http:// classroom.example.com /role1.tar.gz The name of this role should be balancer

http:// classroom.example.com /role2.tar.gz The name of this role should be phphello

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.

Create a playbook called webdev.yml in 'home/sandy/ansible. The playbook will create a directory Avcbdev on dev host. The permission of the directory are 2755 and owner is webdev. Create a symbolic link from /Webdev to /var/www/html/webdev. Serve a file from Avebdev7index.html which displays the text "Development" Curl http://nod e1.example.com/webdev/index.html to test

Using the Simulation Program, perform the following tasks:

1. Use an ansible ad-hoc command, check the connectivity of your servers.

2. Use an ad-hoc ansible command, find the free space of your servers.

3. Use an ad-hoc ansible command, find out the memory usage of your servers.

4. Do an ls -l on the targets /var/log/messages file.

5. Tail the contents of the targets /var/log/messages file.

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

Generate a hosts file:

* Download an initial template file hosts.j2 from http://classroom.example.com/

hosts.j2 to

/home/admin/ansible/ Complete the template so that it can be used to generate a file

with a

line for each inventory host in the same format as /etc/hosts:

172.25.250.9 workstation.lab.example.com workstation

* Create a playbook called gen_hosts.yml that uses this template to generate the file

/etc/myhosts on hosts in the dev host group.

* When completed, the file /etc/myhosts on hosts in the dev host group should have a

line for

each managed host:

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4

::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

172.25.250.10 serevra.lab.example.com servera

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.

user_list.yml file consist:

user:

- name: user1

job: developer

- name: user2

Create a role called sample-apache in /home/sandy/ansible/roles that enables and starts httpd, enables and starts the firewall and allows the webserver service. Create a template called index.html.j2 which creates and serves a message from /var/www/html/index.html Whenever the content of the file changes, restart the webserver service.

Welcome to [FQDN] on [IP]

Replace the FQDN with the fully qualified domain name and IP with the ip address of the node using ansible facts. Lastly, create a playbook in /home/sandy/ansible/ called apache.yml and use the role to serve the index file on webserver hosts.

Create a playbook that changes the default target on all nodes to multi-user tarqet. Do this in playbook file called target.yml in /home/sandy/ansible
