Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q198-Q203):

NEW QUESTION # 198
You have a Kubernetes deployment that runs an application with multiple replicas. When a Pod fails, you need to ensure that the deployment automatically creates a replacement Pod. Which Kubernetes API resource is responsible for this functionality?

Answer: B

Explanation:
The *ReplicaSet• is responsible for ensuring that the desired number of Pods are running for a deployment. It monitors the Pods and automatically replaces failed Pods. Option 'A' is incorrect because services are for exposing applications, not for managing replicas. Option 'C' is incorrect because Pods are individual containers. Option 'D' is incorrect because Deployments use ReplicaSets to manage their replicas. Option 'E' is incorrect because StatefulSets are for managing Pods with unique identities and persistent storage, which is not required in this scenario.


NEW QUESTION # 199
What is the default value for authorization-mode in Kubernetes API server?

Answer: C

Explanation:
The Kubernetes API server supports multiple authorization modes that determine whether an authenticated request is allowed to perform an action (verb) on a resource. Historically, the API server's default authorization mode was AlwaysAllow, meaning that once a request was authenticated, it would be authorized without further checks. That is why the correct answer here is B.
However, it's crucial to distinguish "default flag value" from "recommended configuration." In production clusters, running with AlwaysAllow is insecure because it effectively removes authorization controls-any authenticated user (or component credential) could do anything the API permits. Modern Kubernetes best practices strongly recommend enabling RBAC (Role-Based Access Control), often alongside Node and Webhook authorization, so that permissions are granted explicitly using Roles/ClusterRoles and RoleBindings
/ClusterRoleBindings. Many managed Kubernetes distributions and kubeadm-based setups commonly enable RBAC by default as part of cluster bootstrap profiles, even if the API server's historical default flag value is AlwaysAllow.
So, the exam-style interpretation of this question is about the API server flag default, not what most real clusters should run. With RBAC enabled, authorization becomes granular: you can control who can read Secrets, who can create Deployments, who can exec into Pods, and so on, scoped to namespaces or cluster- wide. ABAC (Attribute-Based Access Control) exists but is generally discouraged compared to RBAC because it relies on policy files and is less ergonomic and less commonly used. AlwaysDeny is useful for hard lockdown testing but not for normal clusters.
In short: AlwaysAllow is the API server's default mode (answer B), but RBAC is the secure, recommended choice you should expect to see enabled in almost any serious Kubernetes environment.

NEW QUESTION # 200
Which of the following is a challenge derived from running cloud native applications?

Answer: D

Explanation:
Cost optimization is complex to maintain across different public cloud environments because cloud native applications often span multiple clouds or hybrid setups, making it challenging to manage and optimize costs consistently.


NEW QUESTION # 201
To visualize data from Prometheus you can use expression browser or console templates. What is the other data visualization tool commonly used together with Prometheus?

Answer: D

Explanation:
The most common visualization tool used with Prometheus is Grafana, so A is correct. Prometheus includes a built-in expression browser that can graph query results, but Grafana provides a much richer dashboarding experience: reusable dashboards, variables, templating, annotations, alerting integrations, and multi-data-source support.
In Kubernetes observability stacks, Prometheus scrapes and stores time-series metrics (cluster and application metrics). Grafana queries Prometheus using PromQL and renders the results into dashboards for SREs and developers. This pairing is widespread because it cleanly separates concerns: Prometheus is the metrics store and query engine; Grafana is the UI and dashboard layer.
Option B (Graphite) is a separate metrics system with its own storage/query model; while Grafana can visualize Graphite too, the question asks what is commonly used together with Prometheus, which is Grafana. Option D (GraphQL) is an API query language, not a metrics visualization tool. Option C ("Nirvana") is not a standard Prometheus visualization tool in common Kubernetes stacks.
In practice, this combo enables operational outcomes: dashboards for error rates and latency (often derived from histograms), capacity monitoring (node CPU/memory), workload behavior (Pod restarts, HPA scaling), and SLO reporting. Grafana dashboards often serve as the shared language during incidents: teams correlate alerts with time-series patterns and quickly identify when regressions began.
Therefore, the verified correct tool commonly used with Prometheus for visualization is Grafana (A).


NEW QUESTION # 202
Which of the following sentences is true about namespaces in Kubernetes?

Answer: B

Explanation:
The true statement is C: the default namespace exists when a new cluster is created. Namespaces are a Kubernetes mechanism for partitioning cluster resources into logical groups. When you set up a cluster, Kubernetes creates some initial namespaces (including default, and commonly kube-system, kube-public, and kube-node-lease). The default namespace is where resources go if you don't specify a namespace explicitly.
Option A is false because namespaces are not hierarchical; Kubernetes does not support "namespaces inside namespaces." Option B is false because within a given namespace, resource names must be unique per resource kind. You can't have two Deployments with the same name in the same namespace. You can have a Deployment named web in one namespace and another Deployment named web in a different namespace-namespaces provide that scope boundary. Option D is false because not all objects are namespaced. Many resources are cluster-scoped (for example, Nodes, PersistentVolumes, ClusterRoles, ClusterRoleBindings, and StorageClasses). Namespaces apply only to namespaced resources.
Operationally, namespaces support multi-tenancy and environment separation (dev/test/prod), RBAC scoping, resource quotas, and policy boundaries. For example, you can grant a team access only to their namespace and enforce quotas that prevent them from consuming excessive CPU/memory. Namespaces also make organization and cleanup easier: deleting a namespace removes most namespaced resources inside it (subject to finalizers).
So, the verified correct statement is C: the default namespace exists upon cluster creation.
