2V0-71.23 Question 45
Select 3A Kubernetes administrator at your organization is tasked with implementing observability for a Tanzu Kubernetes cluster. They must ensure the solution provides comprehensive insights into the cluster's health, application performance, and resource usage. Which components are essential for achieving observability in this scenario?
- A
Metrics collection and visualization tools like Prometheus and Grafana
- B
Distributed tracing tools like Jaeger
- C
A Kubernetes-native storage solution like VMware vSAN
- D
Log aggregation tools like Fluentd or Elasticsearch
- E
A container runtime like containerd
- F
Policy enforcement tools like OPA Gatekeeper
Show answer and explanation
Correct answers: A, B, D
Explanation
Observability in Kubernetes involves monitoring, logging, and tracing to gain insights into cluster health, application performance, and resource usage. Metrics collection tools like Prometheus, distributed tracing solutions like Jaeger, and log aggregation tools like Fluentd work together to achieve this. Components like storage solutions, container runtimes, and policy enforcement tools are important for Kubernetes operations but are not specifically related to observability.
- A. Correct.
Metrics collection and visualization tools like Prometheus and Grafana are critical for monitoring cluster health and resource usage, which are key components of Kubernetes observability.
- B. Correct.
Distributed tracing tools like Jaeger help track requests across various microservices, providing visibility into application performance and latency, which is essential for observability.
- C. Incorrect.
A Kubernetes-native storage solution like VMware vSAN is important for storage management but is not directly related to observability.
- D. Correct.
Log aggregation tools like Fluentd or Elasticsearch are necessary for collecting, indexing, and analyzing logs, which provide insights into cluster and application behavior.
- E. Incorrect.
A container runtime like containerd is required for running containers but does not contribute directly to observability.
- F. Incorrect.
Policy enforcement tools like OPA Gatekeeper are used to enforce compliance and security policies but are not part of an observability solution.
