Linux Foundation Kubernetes and Cloud Native Associate Sample Questions (Q128-Q133):

NEW QUESTION # 128
What is an advantage of using the Gateway API compared to Ingress in Kubernetes?

Answer: B

Explanation:
The Gateway API is a newer Kubernetes networking API designed to address several limitations of the traditional Ingress resource. One of its most significant advantages is the clear separation of roles and responsibilities between infrastructure providers (such as platform teams or cluster administrators) and application developers. This design principle is a core motivation behind the Gateway API and directly differentiates it from Ingress.
With Ingress, a single resource often combines concerns such as load balancer configuration, TLS settings, routing rules, and application-level details. This frequently leads to heavy reliance on annotations, which are controller-specific, non-standardized, and blur ownership boundaries. Application developers may need elevated permissions to modify Ingress objects, even when changes affect shared infrastructure, creating operational risk.
The Gateway API introduces multiple distinct resources-such as GatewayClass, Gateway, and route resources (e.g., HTTPRoute)-each aligned with a specific role. Infrastructure providers manage GatewayClass and Gateway resources, which define how traffic enters the cluster and what capabilities are available. Application developers interact primarily with route resources to define how traffic is routed to their Services, without needing access to the underlying infrastructure configuration. This separation improves security, governance, and scalability in multi-team environments.
Option A is incorrect because automatic scaling based on CPU and memory is handled by the Horizontal Pod Autoscaler, not by Gateway API or Ingress. Option C describes a characteristic of Ingress, not an advantage of Gateway API; in fact, Gateway API explicitly reduces reliance on annotations by using structured, portable fields. Option D is incorrect because exposing applications externally requires more than just a Service; traffic management resources like Ingress or Gateway are still necessary.
Therefore, the correct and verified answer is Option B, as the Gateway API's role-oriented design is a key advancement over Ingress and is clearly documented in Kubernetes networking architecture guidance.


NEW QUESTION # 129
You need to deploy a pod that requires access to a specific GPU device. How can you ensure that
the pod is scheduled on a node with the required GPU?

Answer: D

Explanation:
You can use both the •nodeselector• and •resources' fields to achieve this: 'nodeselector•: Targets nodes with a label indicating the presence of GPUs (e.g., •gpu: true). •resources': Specify the GPU resource requirements within the container's definition. This provides a more precise way to request specific GPUs and their capabilities. While •tolerations' and 'affinity' can be used for other scheduling needs, they are not directly designed for GPU resource allocation.


NEW QUESTION # 130
You're using a cloud provider's managed Kubernetes service with different pricing tiers for nodes. You want to optimize costs by using a mix of node types based on your workload needs. Which of the following is the most appropriate approach?

Answer: B,E

Explanation:
Using a mix of node types based on workload needs is a key cost optimization strategy. Node pools with different node types allow you to run resource-intensive workloads on powerful nodes and less demanding workloads on less expensive nodes. A node selector can be used to target specific pools for deployments. Third-party tools can analyze resource utilization and provide recommendations for node type assignments. Manually choosing node types for each deployment is inefficient and prone to errors. HPA is designed for scaling pods, not choosing node types.
