00:00.000 --> 00:04.320
So friends here is the validation challenge. The very first thing that I would

2
00:04.320 --> 00:05.360
like you to do

3
00:05.360 --> 00:10.960
is to define a variable in the all dot yaml file called ntp_server. Now this

4
00:10.960 --> 00:11.440
should have the

5
00:11.440 --> 00:16.760
value 5.6.7.8. Once you've done that I would like you to write an Ansible

6
00:16.760 --> 00:18.080
playbook to print this

7
00:18.080 --> 00:22.940
variable out for all hosts in your inventory. Next select one device in the

8
00:22.940 --> 00:23.920
inventory and

9
00:23.920 --> 00:29.840
override this ntp_server value that actually inherits from its group membership

10
00:29.840 --> 00:35.280
and give it the value 4.3.2.1 and then rerun the playbook. Now without
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

10
00:29.840 --> 00:35.280
and give it the value 4.3.2.1 and then rerun the playbook. Now without

11
00:35.280 --> 00:37.040
modifying any host or group

12
00:37.040 --> 00:42.560
variable files rerun the playbook and ensure that the ntp_server value is now 1

13
00:42.560 --> 00:44.000
.1.1 for

14
00:44.000 --> 00:48.240
all devices. And then I would like you to create a brand new file with the key

15
00:48.240 --> 00:49.040
value

16
00:49.040 --> 00:54.560
password comma secret one and ensure it is encrypted. Then I would like to view

17
00:54.560 --> 00:55.520
the unencrypted

18
00:55.520 --> 01:00.010
content of this file without actually decrypting the file on disk. And then
WEBVTT
X-TIMESTAMP-MAP=LOCAL:00:00:00.000,MPEGTS:900000

18
00:55.520 --> 01:00.010
content of this file without actually decrypting the file on disk. And then

19
01:00.010 --> 01:01.200
finally I wanted to

20
01:01.200 --> 01:06.030
change the password for this file again without decrypting the file on disk. So

21
01:06.030 --> 01:06.480
again that's

22
01:06.480 --> 01:09.720
a thing but up your terminal and I will see you in the very next video where we

23
01:09.720 --> 01:10.960
discuss the solution.
