問題 #22
Deploy GitOps Application (Subscription YAML)
答案:
解題說明:
See the solution below in Explanation.
Explanation:
* Apply the subscription/application manifest:
* oc apply -f application-subscription.yaml
* Confirm resources were created:
* oc get applications.app.k8s.io -A
* oc get subscriptions.apps.open-cluster-management.io -A
* oc describe application.app.k8s.io my-app -n < namespace >
* Watch placement/propagation (varies by model used in the lab):
* oc get placement -A
* oc get placementrule -A
Why this matters:
* ACM "application" deployment commonly uses Subscription/Placement (legacy model) or newer Placement resources, enabling multi-cluster rollout from Git sources.
問題 #23
Import Cluster (Web Console)
答案:
解題說明:
See the solution below in Explanation.
Explanation:
* In the hub cluster Web Console, go to Infrastructure # Clusters (ACM console navigation).
* Click Import cluster .
* Provide a name (the UI may request details like distribution/credentials depending on flow).
* The wizard will provide a command to run on the managed cluster you want to import.
* Copy that import command.
* Log into the managed cluster (spoke) using oc and run the copied command.
* Back on the hub, wait until the cluster status becomes Ready / Managed .
Why these steps matter:
* Import registers the managed cluster, installs the klusterlet/agent components, and enables policy/app placement management.
問題 #24
Create a Placement that selects clusters in a ManagedClusterSet only
答案:
解題說明:
See the solution below in Explanation.
Explanation:
* Ensure namespace has the correct ManagedClusterSetBinding.
* Create placement in that namespace; only clusters visible via bound ClusterSet can be selected.
* Verify placementdecision includes only clusters from that set.
This ties together ClusterSets (grouping) and Placement (selection).
問題 #25
Create a policy to enforce "etcd encryption enabled" and verify compliance status
答案:
解題說明:
See the solution below in Explanation.
* In ACM console: Governance # Create policy # ETCD Encryption template and set to enforce .
* Target clusters via Placement.
* Confirm policy status: Compliant / NonCompliant per cluster.
問題 #26
Install RHACM Operator (Web Console)
答案:
解題說明:
See the solution below in Explanation.
Explanation:
* Log in to the OpenShift Web Console as a cluster-admin user.
* Go to Operators # OperatorHub .
* OperatorHub is the catalog of available operators.
* In the search box, type: Advanced Cluster Management .
* Click Advanced Cluster Management for Kubernetes (Red Hat ACM).
* Click Install .
* In the install wizard:
* Update channel : choose the recommended/stable channel for your lab.
* Installation mode : typically "All namespaces on the cluster" (default).
* Installed Namespace : select or create open-cluster-management .
* Click Install and wait for the operator to show Succeeded in:
* Operators # Installed Operators .
Why these steps matter:
* Installing the ACM operator creates the CRDs/controllers required to run the Hub components (MultiClusterHub) that manage/import other clusters.
