NEW QUESTION # 158
Imagine there is a requirement to run a database backup every day. Which Kubernetes resource could be used to achieve that?
Answer: C
Explanation:
To run a workload on a repeating schedule (like "every day"), Kubernetes provides CronJob, making B correct. A CronJob creates Jobs according to a cron-formatted schedule, and then each Job creates one or more Pods that run to completion. This is the Kubernetes-native replacement for traditional cron scheduling, but implemented as a declarative resource managed by controllers in the cluster.
For a daily database backup, you'd define a CronJob with a schedule (e.g., "0 2 * * *" for 2:00 AM daily), and specify the Pod template that performs the backup (invokes backup scripts/tools, writes output to durable storage, uploads to object storage, etc.). Kubernetes will then create a Job at each scheduled time. CronJobs also support operational controls like concurrencyPolicy (Allow/Forbid/Replace) to decide what happens if a previous backup is still running, startingDeadlineSeconds to handle missed schedules, and history limits to retain recent successful/failed Job records for debugging.
Option D (Job) is close but not sufficient for "every day." A Job runs a workload until completion once; you would need an external scheduler to create a Job every day. Option A (kube-scheduler) is a control plane component responsible for placing Pods onto nodes and does not schedule recurring tasks. Option C ("Task") is not a standard Kubernetes workload resource.
This question is fundamentally about mapping a recurring operational requirement (backup cadence) to Kubernetes primitives. The correct design is: CronJob triggers Job creation on a schedule; Job runs Pods to completion. Therefore, the correct answer is B.
NEW QUESTION # 159
In Kubernetes, how do Namespaces differ from Labels in managing resources within a cluster?
