20+ practice questions focused on User And RBAC Management — one of the most tested topics on the Red Hat Certified OpenShift Administrator (EX280, OpenShift Container Platform 4.14+) (EX280) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start User And RBAC Management PracticeAn OpenShift cluster uses an external identity provider (IdP). A user named 'alex@example.com' has successfully logged in via the web console. You need to verify which groups this user belongs to from the command line as an administrator. Which command provides this information?
Explanation: The 'oc describe user <username>' command shows the user object's details, including the list of groups the user belongs to, as synced from the identity provider. This is the correct administrative command to inspect group membership for a specific user.
You need to create a new project named 'secure-store' with a specified display name and description, and assign 'jane' as the project admin using the OpenShift CLI. Which command should you execute?
Explanation: The `oc new-project` command creates a new project and allows specifying a display name and description via flags. It also automatically switches the current context to the new project. This is the standard CLI method for creating a project with metadata in OpenShift.
A new user named 'sarah' requires read-only access to all resources within the 'web-frontend' project. Which CLI command creates the appropriate RoleBinding?
Explanation: The 'oc adm policy add-role-to-user' command is the standard helper tool to quickly bind roles to users within a project.
An administrator needs to prevent developers from consuming more than 10 CPU cores and 40Gi of memory collectively across all pods running in the 'production' namespace. Which object satisfies this requirement?
Explanation: A ResourceQuota is a namespace-scoped object that enforces aggregate resource consumption limits across all pods in a namespace. By setting hard limits on requests.cpu and requests.memory (or limits.cpu and limits.memory), it prevents the total consumption from exceeding 10 CPU cores and 40Gi of memory collectively. This directly satisfies the requirement to cap collective usage in the 'production' namespace.
Which OpenShift default role allows a user to see the resources in a project but explicitly prevents them from viewing build configurations, build logs, and secrets?
Explanation: The 'view' role allows viewing most resources, but OpenShift also includes restricted views or specialized roles. Wait, let's check standard roles: 'view' allows viewing almost everything except some sensitive resources like secrets. However, the 'basic-user' role is often used for self-provisioners. Let's look at the 'view' role vs 'basic-user'.
