質問 # 76
How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?
- A. 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.
- B. All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.
- C. All devices that generate syslogs must use agents that process the local logs and transmit them in a specific format to the ELK Stack.
- D. 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.
正解：B
解説：
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.

質問 # 83
An interface on a router as a Layer 3 link has been configured to another device by updating an Ansible playbook that is executed via a CI/CD pipeline. The Ansible playbook was written to push the configuration change using the ios_config module. Which automated test validates that the interface is functioning as it should?
- A. Add a pipeline step that captures and parses the show ip interface output so that the operational state can be referenced.
- B. Automated testing is already built in because the playbook execution is successful only after Ansible validates that it applied the change.
- C. Add a pipeline step that captures and parses the packet flow for the interface.
- D. Add a pipeline step that runs the playbook a second type. If it does not modify the device on the second run, then the interface is correctly configured.

質問 # 86
Refer to the exhibit.
A developer is creating a script to test APIs. The Cisco Webex API and a CI/CD pipeline are tested to ensure that the script runs without problems. The script is executed without issues locally, but the CI/CD system returns the error shown. What is the problem with the script?
- A. The version of Python is wrong in the CI/CD pipeline
- B. The CI/CD system is configured incorrectly to download the required dependencies
- C. The CI/CD system is configured incorrectly to import the dependencies to the code
- D. The code is pushed incorrectly to the CI/CD system
正解：B
解説：
The Cisco Webex API and CI/CD pipeline need to be configured correctly to download the required dependencies in order for the script to run without issues. If the dependencies are not downloaded correctly, the script will fail to run properly and throw an error. The Cisco Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual provides a detailed explanation of how to properly configure the CI/CD pipeline for the Cisco Webex API.
