* The password is stored in the file /home/admin/ansible/password.txt

AExplanation:
Solution as:
# pwd
/home/admin/ansible
# echo 'atenorth' >password.txt
# chmod 0600 password.txt
# ansible-vault create vault.yml --vault-password-file=password.txt

Answer : A

Question 2

Using the Simulation Program, perform the following tasks:

Ad-Hoc Ansible Commands (Number Two) Task:

1. Use the ad-hoc command to make sure php is installed.

2. Use the ad-hoc command to make sure that php is installed and is the latest version.

3. Use the ad-hoc command to make sure that httpd is installed.

4. Use the ad-hoc command to remove httpd from the servers.

AExplanation:
1. ansible all -b -m yum -a 'name=php state=present'
2. ansible all -b -m yum -a 'name=php state=latest'
3. ansible all -b -m yum -a 'name=httpd state=latest'
4. ansible all -b -m yum -a 'name=httpd state=absent'

Answer : A

Question 3

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.

AExplanation:
1. Edit the /etc/ansible/hosts file. Add a group.
2. Edit the /etc/ansible/hosts file. Add a user under the group you created.
3. Edit the /etc/ansible/hosts file. Find a host. if we add a variable called maxRequestsPerChild to the host it would look like this. host1 maxRequestsPerChild=808
4. ansible ec2 -m shell -a 'echo {{ maxRequestsPerChild }}'
5. Edit a local file. It could be called anything. Lets call it myhosts. Inside the file it would have a host like the following. [mygroup] myusername1.mylabserver.com

Answer : A

Question 4

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

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

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

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

questation.

hwreport.txt file consists.

my_sys=hostname

my_BIOS=biosversion

my_MEMORY=memory

my_vda=vdasize

my_vdb=vdbsize

AExplanation:
Solution as:
# pwd
/home/admin/ansible
# vim hwreport.yml
- name:
hosts: all
ignore_errors: yes
tasks:
- name: download file
get_url:
url: http://classroom.example.com/content/ex407/hwreport.empty
dest: /root/hwreport.txt
- name: vdasize
replace:
regexp: 'vdasize'
replace: '{{ ansible_facts.devices.vda.size }}'
dest: /root/hwreport.txt
register: op1
- debug:
var: op1
- name: none
replace:
regexp: 'vdasize'
replace: NONE
dest: /root/hwreport.txt
when:
op1.failed == true
- name: vdbsize
replace:
regexp: 'vdbsize'
replace: '{{ ansible_facts.devices.vdb.size }}'
dest: /root/hwreport.txt
register: op2
- debug:
var: op2
- name: none
replace:
regexp: 'vdbsize'
replace: NONE
dest: /root/hwreport.txt
when:
op2.failed == true
- name: sysinfo
replace:
regexp: '{{item.src}}'
replace: '{{item.dest}}'
dest: /root/hwreport.txt
loop:
- src: 'hostname'
dest: '{{ ansible_facts.fqdn }}'
- src: 'biosversion'
dest: '{{ ansible_facts.bios_version }}'
- src: 'memory'
dest: '{{ ansible_facts.memtotal_mb }}'

Question 6

Create a file called packages.yml in /home/sandy/ansible to install some packages for the following hosts. On dev, prod and webservers install packages httpd, mod_ssl, and mariadb. On dev only install the development tools package. Also, on dev host update all the packages to the latest.

AExplanation:
Solution as:

** NOTE 1 a more acceptable answer is likely 'present' since it's not asking to install the latest
state: present
** NOTE 2 need to update the development node
- name: update all packages on development node
yum:
name: '*'
state: latest

Answer : A

Question 7

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.
