Task 1
Manage Identity Provider
Task information Details: Create the following HTPasswd users: bob, qwerty, john, armstrong, natasha, harry, susan. Create a secret from the HTPasswd file in openshift-config. Configure cluster OAuth to use the HTPasswd identity provider. Restart the OAuth pods so the new authentication configuration takes effect.

  1. See Explanation section for answer.

Answer(s): A

Explanation:

Solution:
Create the initial HTPasswd file with the first user:
htpasswd -c -B -b /tmp/htpass.txt bob indionce
Add the remaining users:
htpasswd -b /tmp/htpass.txt qwerty catalog htpasswd -b /tmp/htpass.txt john john123
htpasswd -b /tmp/htpass.txt armstrong natasha123
htpasswd -b /tmp/htpass.txt natasha arthstrong htpasswd -b /tmp/htpass.txt harry harry123
htpasswd -b /tmp/htpass.txt susan susuan123
Create the secret in openshift-config:
oc create secret generic ex280-secure --from-file=htpasswd=/tmp/htpass.txt -n openshift-config
Edit OAuth and add the HTPasswd identity provider:
oc edit oauth cluster
Use a valid structure like this:
spec:
identityProviders:
- name: ex280-idp-secure mappingMethod: claim type: HTPasswd htpasswd:
fileData:
name: ex280-secure
Save and exit.
Restart OAuth pods:
oc delete pod -n openshift-authentication -l app=oauth-openshift

Grant cluster-admin to bob:
oc adm policy add-cluster-role-to-user cluster-admin bob
Disable normal self-provisioning for authenticated users:
oc adm policy remove-cluster-role-from-group self-provisioner system:authenticated:oauth
Allow john to self-provision:
oc adm policy add-cluster-role-to-user self-provisioner john
Give natasha view access in test and apollo:
oc policy add-role-to-user view natasha -n test oc policy add-role-to-user view natasha -n apollo
Give armstrong admin in apollo:
oc policy add-role-to-user admin armstrong -n apollo
Remove kubeadmin secret:
oc delete secret kubeadmin -n kube-system
Verify permissions:
oc adm policy who-can create projectrequests oc describe rolebinding.rbac -n apollo oc describe rolebinding.rbac -n test

took the test last week, i did have about 15 - 20 word for word from this site on the test. (only was able to cram 600 of the questions from this site so maybe more were there i didnt review) had 4 labs, bgp, lacp, vrf with tunnels and actually had to skip a lab due to time. lots of automation syntax questions.

answer to this question "what administrative safeguards should be implemented to protect the collected data while in use by manasa and her product management team? " it should be (c) for the following reasons: this administrative safeguard involves controlling access to collected data by ensuring that only individuals who need the data for their job responsibilities have access to it. this helps minimize the risk of unauthorized access and potential misuse of sensitive information. while other options such as (a) documenting data flows and (b) conducting a privacy impact assessment (pia) are important steps in data protection, implementing a "need to know" access policy directly addresses the issue of protecting data while in use by limiting access to those who require it for legitimate purposes. (d) is not directly related to safeguarding data during use; it focuses on data transfers and location.

password lockout being the correct answer for question 37 does not make sense. it should be geofencing.
