Understanding Kibana's Role

What is the primary purpose of Kibana in the Elastic Stack?

A To store and index data for fast search and analytics

B To visualize and explore data stored in Elasticsearch

C To ingest and transform data before indexing

D To secure Elasticsearch clusters with authentication

💡 Hint

Think about which tool helps you see and interact with your data.

Kibana is the visualization layer of the Elastic Stack. It connects to Elasticsearch and lets users create charts, dashboards, and explore data visually.

Kibana Connection URL Format

Given the following Kibana configuration snippet, what is the URL Kibana will use to connect to Elasticsearch?

elasticsearch.hosts: ["http://localhost:9200"]

A http://localhost:5601

B http://localhost:9300

C http://localhost:9200

D https://localhost:9200

💡 Hint

Look at the port number and protocol in the configuration.

The configuration shows Kibana connecting to Elasticsearch at http://localhost:9200, which is the default Elasticsearch HTTP port.

Troubleshooting Kibana Connection Error

You see this error in Kibana logs: Unable to connect to Elasticsearch at http://localhost:9200. Which of the following is the most likely cause?

A Elasticsearch index patterns are not created in Kibana

B Kibana is running on the wrong port 5602 instead of 5601

C Kibana configuration file is missing the <code>server.host</code> setting

D Elasticsearch is not running or not reachable at the specified URL

💡 Hint

Think about what would cause a connection failure to Elasticsearch.

If Kibana cannot connect to Elasticsearch, it usually means Elasticsearch is down, unreachable, or the URL is incorrect. Other options do not directly cause connection failures.

Correct Kibana Configuration for Elasticsearch Connection

Which of the following Kibana configuration lines correctly sets the Elasticsearch hosts to connect to a cluster running on https://es.example.com:9200?

A elasticsearch.hosts: ["https://es.example.com:9200"]

B elasticsearch.hosts = https://es.example.com:9200

C elasticsearch.hosts: "https://es.example.com:9200"

D elasticsearch.hosts: https://es.example.com:9200

💡 Hint

Remember the YAML syntax for lists and strings.

The correct syntax uses a YAML list with square brackets and quotes around the URL. Options B, C, and D are invalid YAML or missing list brackets.

Kibana Dashboard Access Control Setup

You want to restrict access to certain Kibana dashboards based on user roles. Which Elastic Stack feature should you configure to achieve this?

A Kibana Spaces with Role-Based Access Control (RBAC)

B Elasticsearch Index Lifecycle Management (ILM)

C Elasticsearch Snapshot and Restore

D Kibana Canvas Workpads

💡 Hint

Think about how Kibana organizes dashboards and controls user permissions.

Kibana Spaces allow grouping dashboards and visualizations, and combined with RBAC, you can restrict user access to specific spaces and dashboards.
