Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q173-Q178):

NEW QUESTION # 173
What Linux namespace is shared by default by containers running within a Kubernetes Pod?

Answer: D

Explanation:
By default, containers in the same Kubernetes Pod share the network namespace, which means they share the same IP address and port space. Therefore, the correct answer is B (Network).
This shared network namespace is a key part of the Pod abstraction. Because all containers in a Pod share networking, they can communicate with each other over localhost and coordinate tightly, which is the basis for patterns like sidecars (service mesh proxies, log shippers, config reloaders). It also means containers must coordinate port usage: if two containers try to bind the same port on 0.0.0.0, they'll conflict because they share the same port namespace.
Option A ("Host Network") is different: hostNetwork: true is an optional Pod setting that puts the Pod into the node's network namespace, not the Pod's shared namespace. It is not the default and is generally used sparingly due to security and port-collision risks. Option C ("Process ID") is not shared by default in Kubernetes; PID namespace sharing requires explicitly enabling process namespace sharing (e.g., shareProcessNamespace: true). Option D ("Process Name") is not a Linux namespace concept.
The Pod model also commonly implies shared storage volumes (if defined) and shared IPC namespace in some configurations, but the universally shared-by-default namespace across containers in the same Pod is the network namespace. This default behavior is why Kubernetes documentation explains a Pod as a "logical host" for one or more containers: the containers are co-located and share certain namespaces as if they ran on the same host.
So, the correct, verified answer is B: containers in the same Pod share the Network namespace by default.


NEW QUESTION # 174
What is the purpose of the "securityContext" field in a pod specification? Choose all that apply.

Answer: B,E

Explanation:
The "securityContext" field in a pod specification is used to define the security context of the containers within the pod. This includes settings related to user ID and group ID, SELinux and AppArmor profiles, and other security-related options. It does not control access to the Kubernetes API server, configure resource limits, or specify the network namespace.


NEW QUESTION # 175
How long should a stable API element in Kubernetes be supported (at minimum) after deprecation?

Answer: D

Explanation:
Kubernetes has a formal API deprecation policy to balance stability for users with the ability to evolve the platform. For a stable (GA) API element, Kubernetes commits to supporting that API for a minimum period after it is deprecated. The correct minimum in this question is 12 months, which corresponds to option C.
In practice, Kubernetes releases occur roughly every three to four months, and the deprecation policy is commonly communicated in terms of "releases" as well as time. A GA API that is deprecated in one release is typically kept available for multiple subsequent releases, giving cluster operators and application teams time to migrate manifests, client libraries, controllers, and automation. This matters because Kubernetes is often at the center of production delivery pipelines; abrupt API removals would break deployments, upgrades, and tooling. By guaranteeing a minimum support window, Kubernetes enables predictable upgrades and safer lifecycle management.
This policy also encourages teams to track API versions and plan migrations. For example, workloads might start on a beta API (which can change), but once an API reaches stable, users can expect a stronger compatibility promise. Deprecation warnings help surface risk early. In many clusters, you'll see API server warnings and tooling hints when manifests use deprecated fields/versions, allowing proactive remediation before the removal release.
Options 6 or 9 months would be too short for many enterprises to coordinate changes across multiple teams and environments. 24 months may be true for some ecosystems, but the Kubernetes stated minimum in this exam-style framing is 12 months. The key operational takeaway is: don't ignore deprecation notices-they're your clock for migration planning. Treat API version upgrades as part of routine cluster lifecycle hygiene to avoid being blocked during Kubernetes version upgrades when deprecated APIs are finally removed.


NEW QUESTION # 176
Which control plane component is responsible for scheduling pods?

Answer: C
