NEW QUESTION # 124
DNS issues are suspected inside a Pod. Which command is most useful to verify the problem?
Answer: B
Explanation:
Executing nslookup inside the Pod tests DNS resolution from the Pod's own network namespace, directly verifying whether service names can be resolved as expected.
NEW QUESTION # 125
Which resource do you use to attach a volume in a Pod?
Answer: C
Explanation:
In Kubernetes, Pods typically attach persistent storage by referencing a PersistentVolumeClaim (PVC), making D correct. A PVC is a user's request for storage with specific requirements (size, access mode, storage class). Kubernetes then binds the PVC to a matching PersistentVolume (PV) (either pre-provisioned statically or created dynamically via a StorageClass and CSI provisioner). The Pod does not directly attach a PV; it references the PVC, and Kubernetes handles the binding and mounting.
This design separates responsibilities: administrators (or CSI drivers) manage PV provisioning and backend storage details, while developers consume storage via PVCs. In a Pod spec, you define a volume of type persistentVolumeClaim and set claimName: <pvc-name>, then mount that volume into containers at a path. The kubelet coordinates with the CSI driver (or in-tree plugin depending on environment) to attach/mount the underlying storage to the node and then into the Pod.
Option B (PersistentVolume) is not directly referenced by Pods; PVs are cluster resources that represent actual storage. Pods don't "pick" PVs; claims do. Option C (StorageClass) defines provisioning parameters (e.g., disk type, replication, binding mode) but is not what a Pod references to mount a volume. Option A is not a Kubernetes resource type.
Operationally, using PVCs enables dynamic provisioning and portability: the same Pod spec can be deployed across clusters where the StorageClass name maps to appropriate backend storage. It also supports lifecycle controls like reclaim policies (Delete/Retain) and snapshot/restore workflows depending on CSI capabilities.
So the Kubernetes resource you use in a Pod to attach a persistent volume is PersistentVolumeClaim, option D.
NEW QUESTION # 126
During a team meeting, a developer mentions the significance of open collaboration in the cloud native ecosystem. Which statement accurately reflects principles of collaborative development and community stewardship?
Answer: D
Explanation:
Collaborative development in the cloud native ecosystem is built on open collaboration, where community events and working groups enable knowledge sharing, collective problem solving, and relationship building, all of which are essential for healthy, sustainable open source projects.
NEW QUESTION # 127
