Answer: C
NEW QUESTION # 168
You have a Kubernetes cluster with multiple namespaces. You are running different applications in separate namespaces and want to ensure that HPAs in each namespace are not interfering with each other. Which of the following measures should you take?
Answer: C,D
Explanation:
You need to ensure that HPAs are not competing for resources across namespaces- Resource quotas (C) limit resource consumption within each namespace, preventing HPAs from consuming resources intended for other applications. A custom controller (D) can be used to manage HPAs across multiple namespaces, coordinating scaling decisions to avoid resource contention and optimize utilization across the cluster. While options A and B might seem relevant, they are not effective solutions for preventing interference between HPAs in different namespaces. Option E is incorrect; HPAs operate within their namespaces, but resource contention can occur if not managed properly.
NEW QUESTION # 169
You are using a CI/CD pipeline with Jenkins to deploy applications to Kubernetes. Which of the following strategies can be used to handle sensitive credentials (e.g., API keys, database passwords) within the pipeline?
Answer: D,E
Explanation:
Storing sensitive credentials in Kubernetes Secrets or using a dedicated secret management tool like Vault is the most secure approach. These solutions provide controlled access, encryption, and auditing capabilities, ensuring your credentials remain protected throughout the CI/CD process.
NEW QUESTION # 170
How does dynamic storage provisioning work?
Answer: D
Explanation:
Dynamic provisioning is the Kubernetes mechanism where storage is created on-demand when a user creates a PersistentVolumeClaim (PVC) that references a StorageClass, so A is correct. In this model, the user does not need to pre-create a PersistentVolume (PV). Instead, the StorageClass points to a provisioner (typically a CSI driver) that knows how to create a volume in the underlying storage system (cloud disk, SAN, NAS, etc.). When the PVC is created with storageClassName: <class>, Kubernetes triggers the provisioner to create a new volume and then binds the resulting PV to that PVC.
This is why option B is incorrect: you do not put a StorageClass "in the Pod YAML" to request provisioning.
Pods reference PVCs, not StorageClasses directly. Option C is incorrect because the PVC does not need the Pod name; binding is done via the PVC itself. Option D describes static provisioning: an admin pre-creates PVs and users claim them by creating PVCs that match the PV (capacity, access modes, selectors). Static provisioning can work, but it is not dynamic provisioning.
Under the hood, the StorageClass can define parameters like volume type, replication, encryption, and binding behavior (e.g., volumeBindingMode: WaitForFirstConsumer to delay provisioning until the Pod is scheduled, ensuring the volume is created in the correct zone). Reclaim policies (Delete/Retain) define what happens to the underlying volume after the PVC is deleted.
In cloud-native operations, dynamic provisioning is preferred because it improves developer self-service, reduces manual admin work, and makes scaling stateful workloads easier and faster. The essence is: PVC + StorageClass # automatic PV creation and binding.
