NEW QUESTION # 53
Which Kubernetes resource provides standardized load balancing, TLS termination, and multi- context traffic routing across different implementations?
Answer: D
Explanation:
The Gateway API defines a standardized, extensible model for traffic management that includes load balancing, TLS termination, and advanced routing across different implementations, improving consistency compared to earlier approaches.
NEW QUESTION # 54
You are running a resource-intensive application in Kubernetes. You want to reduce costs without impacting performance. Which of the following approaches would be most effective?
Answer: C,E
Explanation:
For resource-intensive applications, the most effective cost reduction strategies focus on optimizing resource usage and application efficiency. Vertical pod autoscaling (VPA) dynamically adjusts resource allocation based on actual usage, ensuring pods have sufficient resources without overprovisioning. Optimizing the application code itself to reduce resource consumption is crucial, as it can significantly impact overall cost. While decreasing replicas or reducing requests/limits might seem tempting, they can negatively impact performance. Migrating to a different cloud provider might offer cost advantages, but it's a complex and potentially disruptive process.
NEW QUESTION # 55
You are running a containerized application that requires access to a specific host-mounted directory. Which of the following is the most appropriate Kubernetes mechanism to achieve this?
Answer: C
Explanation:
The *VolumeMountS section within a Pod definition allows you to map host directories or persistent volumes into your container. This provides a secure and controlled way to access files from the host machine within your container. HostPort, Service Account, Pod Security Policy, and ConfigMap are all different Kubernetes concepts and do not directly address the need for host directory access.
NEW QUESTION # 56
Which Kubernetes-native deployment strategy supports zero-downtime updates of a workload?
Answer: C
Explanation:
D (RollingUpdate) is correct. In Kubernetes, the Deployment resource's default update strategy is RollingUpdate, which replaces Pods gradually rather than all at once. This supports zero-downtime updates when the workload is properly configured (sufficient replicas, correct readiness probes, and appropriate maxUnavailable / maxSurge settings). As new Pods come up and become Ready, old Pods are terminated in a controlled way, keeping the service available throughout the rollout.
RollingUpdate's "zero downtime" is achieved by maintaining capacity while transitioning between versions. For example, with multiple replicas, Kubernetes can create new Pods, wait for readiness, then scale down old Pods, ensuring traffic continues to flow to healthy instances. Readiness probes are critical: they prevent traffic from being routed to a Pod until it's actually ready to serve.
Why other options are not the Kubernetes-native "strategy" answer here:
Recreate (B) explicitly stops old Pods before starting new ones, causing downtime for most services.
Canary (A) and BlueGreen (C) are real deployment patterns, but in "Kubernetes-native deployment strategy" terms, the built-in Deployment strategies are RollingUpdate and Recreate. Canary/BlueGreen typically require additional tooling/controllers (service mesh, ingress controller features, or progressive delivery operators) to manage traffic shifting between versions.
So, for a Kubernetes-native strategy that supports zero-downtime updates, the correct and verified choice is RollingUpdate (D).
NEW QUESTION # 57
In a Kubernetes environment, how is an Argo CD ApplicationSet configured to ensure continuous deployment of an application?
Answer: D
Explanation:
An Argo CD ApplicationSet is defined declaratively and connected to a Git repository that contains the application manifests. Argo CD continuously monitors the repository and automatically syncs the cluster state with the desired state defined in Git, enabling continuous deployment.
