                                      Create Secret with Name Magic in Math Project
                                      Task information Details:
                                      Create a secret named magic in the math project that stores MYSQL_ROOT_PASSWORD=redhat .

                                      Answer:

                                      Explanation:
                                      See the solution below in Explanation.
                                      Explanation:
                                      Solution:
                                      * Switch to the math project:
                                      oc project math
                                      * Create the secret:
                                      oc create secret generic magic --from-literal=MYSQL_ROOT_PASSWORD=redhat
                                      * Verify:
                                      oc get secret magic
                                      oc describe secret magic
                                      Note:
                                      * The uploaded lab text contains a typo --from-listeral; the valid option is --from-literal.
                                      * The output in the lab also appears inconsistent. The intended secret name is magic .
                                      This task checks secret creation and secure configuration data handling.


                                      NEW QUESTION # 12
                                      Create Service Account in QED

                                      Grant the anyuid SCC to that service account.

                                      Answer:

                                      Explanation:
                                      See the solution below in Explanation.
                                      Explanation:
                                      Solution:
                                      * Switch to the project:
                                      oc project qed
                                      * Create the service account:
                                      oc create serviceaccount project1-sa -n qed
                                      * Grant the SCC:
                                      oc adm policy add-scc-to-user anyuid -z project1-sa -n qed
                                      * Verify:
                                      oc get sa project1-sa -n qed
                                      oc adm policy who-can use scc anyuid
                                      Why this matters:
                                      * anyuid allows containers to run with arbitrary user IDs when an application requires it.
                                      * This is a common administrative task in OpenShift for third-party container images.
                                      This task validates service account creation and SCC assignment.
