NEW QUESTION # 47
How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?
- A. A single, comprehensive log format is defined on the ELK Stack. All incoming logs, regardless of format, are transformed to match the comprehensive format, and only applicable fields are populated.
- B. All devices that generate syslogs must use agents that process the local logs and transmit them in a specific format to the ELK Stack.
- C. All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.
- D. All logs are stored in their unstructured text format, and the ELK Stack performs data analysis by intelligently parsing the logs using machine learning algorithms.
Answer: C
Explanation:
Explanation
The ELK Stack (Elasticsearch, Logstash, and Kibana) can handle ingesting unstructured logs from various devices in different formats by running custom filters on the logs. The filters are designed to parse the log data and extract the relevant, structured information from it, which is then stored for later analysis. This allows for faster and more accurate analysis of the data, and enables more sophisticated insights to be drawn from it.
NEW QUESTION # 48
Which step must be taken to enable centralized logging in a Kubernetes environment?
- A. Deploy a sidecar node that aggregates logs from the entire cluster.
- B. No steps need to be taken. The master node automatically aggregates logs from all worker nodes and stores them on the specified persistent volume.
- C. Create a CustomResourceDefinition in each deployment that specifies the IP or names the log collector.
- D. Create a DaemonSet that deploys a container with a logging agent on every node in the cluster.
Answer: D
Explanation:
Explanation
To enable centralized logging in a Kubernetes environment, you must create a DaemonSet that deploys a container with a logging agent on every node in the cluster. This allows all of the logs from each node to be collected in one place, allowing for easier analysis and management. Reference: Kubernetes Documentation, Logging Architecture.
