Kubernetes and Cloud Native Associate certification is also beneficial for organizations that want to ensure that their IT teams have the necessary skills and knowledge to develop and deploy cloud-native applications.
The Linux Foundation KCNA Exam is designed to test the candidate's knowledge and understanding of Kubernetes and cloud-native technologies. It covers a range of topics such as deploying, managing, and scaling applications in Kubernetes, understanding Kubernetes architecture and components, and configuring Kubernetes networking and security. KCNA exam also tests the candidate's knowledge of containerization technologies such as Docker and container orchestration tools like Helm.
NEW QUESTION # 174
A request for 500 mebibytes of ephemeral storage must be specified in a YAMLfile. How should this be written?
Answer: C
Explanation:
Kubernetes resource quantities use binary units for mebibytes, and 500Mi correctly represents a request for 500 mebibytes of ephemeral storage in a YAML specification.
NEW QUESTION # 175
Which statement about Ingress is correct?
Answer: C
Explanation:
Ingress is the Kubernetes API resource for defining external HTTP/HTTPS routing into the cluster, so D is correct. An Ingress object specifies rules such as hostnames (e.g., app.example.com), URL paths (e.g., /api), and TLS configuration, mapping those routes to Kubernetes Services. This provides Layer 7 routing capabilities beyond what a basic Service offers.
Ingress is not a Service type (so B is wrong). Service types (ClusterIP, NodePort, LoadBalancer, ExternalName) are part of the Service API and operate at Layer 4. Ingress is a separate API object that depends on an Ingress Controller to actually implement routing. The controller watches Ingress resources and configures a reverse proxy/load balancer (like NGINX, HAProxy, or a cloud load balancer integration) to enforce the desired routing. Without an Ingress Controller, creating an Ingress object alone will not route traffic.
Option A describes endpoint tracking (that's closer to Endpoints/EndpointSlice). Option C describes NetworkPolicy, which controls allowed network flows between Pods/namespaces. Ingress is about exposing and routing incoming application traffic from outside the cluster to internal Services.
So the verified correct statement is D: Ingress exposes routes from outside the cluster to Services in the cluster.

NEW QUESTION # 176
You want to deploy a new microservice to your Kubernetes cluster using GitOps principles. Which of
the following approaches would you use to manage the deployment process?
Answer: B
Explanation:
GitOps emphasizes the use of Git as the single source of truth for managing your cluster's desired state. Option C correctly describes the GitOps approach by storing the configuration in a Git repository and using a GitOps tool to manage deployments, ensuring consistency and traceability.
NEW QUESTION # 177
Kubernetes ___ protect you against voluntary interruptions (such as deleting Pods, draining nodes) to run applications in a highly available manner.
Answer: B
Explanation:
The correct answer is B: Pod Disruption Budgets (PDBs). A PDB is a policy object that limits how many Pods of an application can be voluntarily disrupted at the same time. "Voluntary disruptions" include actions such as draining a node for maintenance (kubectl drain), cluster upgrades, or an administrator deleting Pods. The core purpose is to preserve availability by ensuring that a minimum number (or percentage) of replicas remain running and ready while those planned disruptions occur.
A PDB is typically defined with either minAvailable (e.g., "at least 3 Pods must remain available") or maxUnavailable (e.g., "no more than 1 Pod can be unavailable"). Kubernetes uses this budget when performing eviction operations. If evicting a Pod would violate the PDB, the eviction is blocked (or delayed), which forces maintenance workflows to proceed more safely-either by draining more slowly, scaling up first, or scheduling maintenance in stages.
Why the other options are not correct: topology spread constraints (A) influence scheduling distribution across failure domains but don't directly protect against voluntary disruptions. Taints and tolerations (C) control where Pods can schedule, not how many can be disrupted. Resource requests/limits (D) control CPU/memory allocation and do not guard availability during drains or deletions.
PDBs also work best when paired with Deployments/StatefulSets that maintain replicas and with readiness probes that accurately represent whether a Pod can serve traffic. PDBs do not prevent involuntary disruptions (node crashes), but they materially reduce risk during planned operations-exactly what the question is targeting.
NEW QUESTION # 178
You are implementing a new security policy for your Kubernetes cluster. The policy requires that all pods running in the cluster must authenticate with a specific identity provider before they are allowed to access any resources. Which Kubernetes component is responsible for enforcing this authentication policy?
Answer: D
Explanation:
The kube-apiserver component acts as the central control plane for Kubernetes. It handles all communication and requests from other components, including authentication and authorization. It enforces security policies by verifying credentials and granting access based on configured rules.
