NEW QUESTION # 172
Your Kubernetes cluster has a limited number of nodes, and you need to efficiently utilize those resources. You are deploying a highly scalable web application with multiple pods. What Kubernetes concept can help you optimize resource allocation and ensure pods are scheduled across all available nodes?

A. Taints
B. PodAntiAffinity
C. Tolerations
D. ResourceQuota
E. NodeSelector

Answer: A,B,C,E

Explanation:
These concepts help you optimize resource allocatiom 1 - NodeSelector Allows you to specify labels on nodes and match those labels in your pod definitions, ensuring pods are scheduled on nodes with desired characteristics. 2. PodAntiAffnity: Prevents pods from being scheduled on the same node or even within the same zone, promoting distribution across nodes. 3- Tolerations: Allow pods to tolerate taints applied to nodes. Taints are used to mark nodes as unsuitable for certain pods unless those pods have the corresponding tolerances. 4. Taints: Mark nodes with specific characteristics, preventing pods from scheduling on those nodes unless they have tolerations for those taints. ResourceQuota restricts resources at a namespace level, but not node-level scheduling.

NEW QUESTION # 173

A. Namespace
B. Service
C. Secret
D. PersistentVolumeClaim
E. ConfigMap

Answer: C

Explanation:
Secrets are Kubernetes resources that allow you to store sensitive information, such as passwords, API keys, and certificates. You can then mount Secrets into Pods, allowing them to securely access the information they need without exposing it in plain text.
