NEW QUESTION # 188
What is the practice of bringing financial accountability to the variable spend model of cloud resources?
Answer: D
Explanation:
The practice of bringing financial accountability to cloud spending-where costs are variable and usage-based-is called FinOps, so D is correct. FinOps (Financial Operations) is an operating model and culture that helps organizations manage cloud costs by connecting engineering, finance, and business teams. Because cloud resources can be provisioned quickly and billed dynamically, traditional budgeting approaches often fail to keep pace. FinOps addresses this by introducing shared visibility, governance, and optimization processes that enable teams to make cost-aware decisions while still moving fast.
In Kubernetes and cloud-native architectures, variable spend shows up in many ways: autoscaling node pools, over-provisioned resource requests, idle clusters, persistent volumes, load balancers, egress traffic, managed services, and observability tooling. FinOps practices encourage tagging/labeling for cost attribution, defining cost KPIs, enforcing budget guardrails, and continuously optimizing usage (right-sizing resources, scaling policies, turning off unused environments, and selecting cost-effective architectures).
Why the other options are incorrect: FaaS (Function as a Service) is a compute model (serverless), not a financial accountability practice. DevOps is a cultural and technical practice focused on collaboration and delivery speed, not specifically cloud cost accountability (though it can complement FinOps). CloudCost is not a widely recognized standard term in the way FinOps is.
In practice, FinOps for Kubernetes often involves improving resource efficiency: aligning requests/limits with real usage, using HPA/VPA appropriately, selecting instance types that match workload profiles, managing cluster autoscaler settings, and allocating shared platform costs to teams via labels/namespaces. It also includes forecasting and anomaly detection, because cloud-native spend can spike quickly due to misconfigurations (e.g., runaway autoscaling or excessive log ingestion).
So, the correct term for financial accountability in cloud variable spend is FinOps (D).
NEW QUESTION # 189
You're running a web application in Kubernetes that experiences occasional spikes in traffic. You want to scale your application horizontally to handle these spikes automatically. What Kubernetes resource should you utilize to achieve this?
Answer: C
Explanation:
A HonzontalPodAutoscaler (HPA) is the primary resource in Kubernetes for automatically scaling Pods based on resource utilization (CPU, memory, etc.) or custom metrics. Deployments, StatefulSets, and DaemonSets define the deployment and management of Pods, while Services handle load balancing and access to the application.
NEW QUESTION # 190
You have deployed an application in Kubernetes with a container image that has known vulnerabilities. Which of the following security measures is MOST effective in mitigating the risk of these vulnerabilities?
Answer: A
Explanation:
Using a container security scanner to identify and fix vulnerabilities is the most effective measure for mitigating the risk of known vulnerabilities in your container images. These scanners analyze your images for known security issues and provide recommendations for patching or upgrading them. This helps you proactively address potential vulnerabilities and improve the overall security of your Kubernetes applications.
NEW QUESTION # 191
What is the correct method to access an internal service by forwarding a local port to a specific port inside a Pod running in a Kubernetes cluster?
Answer: A
Explanation:
The kubectl port-forward command forwards a local port to a specific port on a Pod or Service, enabling direct access to an internal application running inside the Kubernetes cluster from a local machine.
NEW QUESTION # 192
You are running a multi-cluster Kubernetes environment with Istio deployed. You need to ensure that communication between services across different clusters is secure and encrypted. What Istio configuration would you use to achieve this?
Answer: B
Explanation:
To secure inter-cluster communication with Istio, you need to enable Mutual TLS (mTLS) authentication. This ensures that all communication between services, even across different clusters, is encrypted and verified. Options A and B are partially correct but dont cover the full scope of inter-cluster security. Option C is not recommended as it creates complexity in managing multiple control planes. Option E is used for managing ingress and egress traffic but doesn't directly address inter-cluster security
