EX280 Security And SCC Practice Question
A developer deploys a custom application pod that requires the hostIPC capability, but the pod creation is rejected by the apiserver. Upon inspecting the cluster SCCs, the administrator determines that the application uses a ServiceAccount named app-sa in the production namespace. How should the administrator grant the restricted SCC privileges safely without compromising cluster security?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a RoleBinding in the production namespace referencing the system:openshift:scc:hostaccess cluster role and the app-sa ServiceAccount
To grant specific SCC privileges, the administrator must bind the SCC's corresponding cluster role to the target service account.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Add a subject entry referencing system:serviceaccount:production:app-sa to the users list inside the restricted SCC definition
Why it's wrong here
Modifying predefined system SCC objects directly is an unsupported anti-pattern and can be overwritten during cluster upgrades.
- ✓
Create a RoleBinding in the production namespace referencing the system:openshift:scc:hostaccess cluster role and the app-sa ServiceAccount
Why this is correct
RoleBindings targeting the system:openshift:scc:hostaccess cluster role grant the necessary elevated SCC permissions to the specified ServiceAccount within that namespace.
- ✗
Annotate the app-sa ServiceAccount with openshift.io/scc.constraint: hostaccess
Why it's wrong here
Service accounts do not use annotations to bind SCCs; they rely on ClusterRoleBindings or RoleBindings targeting the scc cluster roles.
- ✗
Create a ClusterRoleBinding that binds the system:openshift:scc:restricted cluster role to system:serviceaccount:production:app-sa
Why it's wrong here
The restricted SCC does not allow hostIPC. The correct SCC that permits hostIPC is hostaccess or a custom SCC.
