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
Verify:
oc get pods -n openshift-authentication oc get oauth cluster -o yaml
This task validates OpenShift local authentication configuration through HTPasswd and cluster OAuth integration.

  1. See Explanation section for answer.

Answer(s): A

Explanation:

Solution:
Create the projects:
oc new-project apollo oc new-project test oc new-project demo
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

question 35 is incorrect, the correct answer is c, it even states so: explanation: when a vm is infected with ransomware, you should not restore the vm to the infected vm. this is because the ransomware will still be present on the vm, and it will encrypt the files again. you should also not restore the vm to any vm within the companys subscription. this is because the ransomware could spread to other vms in the subscription. the best way to restore a vm that is infected with ransomware is to restore it to a new azure vm. this will ensure that the ransomware is not present on the new vm.
