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 CI/CD system is configured incorrectly to download the required dependencies
- B. The code is pushed incorrectly to the CI/CD system
- C. The version of Python is wrong in the CI/CD pipeline
- D. The CI/CD system is configured incorrectly to import the dependencies to the code
Answer: A
Explanation:
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.

How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?
- A. All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.
- 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.

- 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: A
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.

According to the Cisco Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, "A webhook is a web-based feature that enables a remote service to communicate with a local service, usually through a web server. Webhooks are used to trigger an action when a specific event occurs, usually in a remote service or application."
