Cisco 300-910 Online Questions & Answers

• Question 1:

  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 import the dependencies to the code
  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 download the required dependencies
  D. The CI/CD system is configured incorrectly to download the required dependencies

  ---

  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.

• Question 2:

  Which type of testing should be integrated into a CI/CD pipeline to ensure the correct behavior of all of the modules in the source code that were developed using TDD?

  A. soak testing
  B. unit testing
  C. load testing
  D. volume testing
  B. unit testing

• Question 3:

  A development team uses Kubernetes for application development. Any changes on ConfigMap are performed manually for each development, test, and production environment. The edits are performed to deploy applications. This approach causes inconsistent deployments across all environments.

  Which practice improves the consistency of the deployments?

  A. Implement environment variables within the ConfigMaps and store the variable definitions separately from the master branch where the ConfigMaps are stored
  B. Generate the ConfigMaps specific to the environment by using a templating language such as Jinja2 and store the ConfigMaps in unique branches of a repository
  C. In the master branch where the ConfigMaps are stored, create a branch for each environment that contains an environment-specific ConfigMap.
  D. Create a unique repository for each environment that contains ConfigMaps for that environment to ensure that each environment can be deployed independently
  A. Implement environment variables within the ConfigMaps and store the variable definitions separately from the master branch where the ConfigMaps are stored

• Question 4:

  Refer to the exhibit.

  

  What is causing the requests code to fail?

  A. Rython3 is not compatible with requests.
  B. The requests library is not imported.
  C. The requests library is not installed.
  D. The requests coming into stdin fail because device_ip cannot be parsed.
  B. The requests library is not imported.

• Question 5:

  An application for storing and categorizing has been developed. The application uses dual- factor authentication for user access. After authentication, users can upload sensitive data. The application has been hacked through system exploits and most of the saved data has been lost.

  Which action prevents new security threats in the environment?

  A. Use self-developed algorithms for encryption
  B. Install virtual firewalls
  C. Actively change the ISP provider
  D. Apply all the latest patches and updates
  D. Apply all the latest patches and updates

• Question 6:

  What is the impact of using the Drone.io CI/CD tool on the local installation step?

  A. slows down the development
  B. delays the deployment of components
  C. speeds up the procedure
  D. complicates the application process
  C. speeds up the procedure

• Question 7:

  How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?

  A. All devices that generate syslogs must use agents that process the local logs and transmit them in a specific format to the ELK Stack.
  B. 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.
  C. All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.
  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.
  C. All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.

  ---

  Explanation Explanation/Reference: 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.

• Question 8:

  What are two reasons a Docker golden image should be updated? (Choose two.)

  A. when there is a change to a username or password in the Docker secrets
  B. when the application has a new release
  C. when a fix for a security vulnerability is released
  D. when a change is needed to an environment variable in the Dockerfile
  E. when the base image is nearing the end of life
  B. when the application has a new release
  C. when a fix for a security vulnerability is released

• Question 9:

  DRAG DROP

  Drag and drop the operations from the left into the correct order on the right when using CI/CD, assuming that there are no failures or conflicts.

  Select and Place:

  

  

• Question 10:

  Which two practices help make the security of an application a more integral part of the software development lifecycle? (Choose two.)

  A. Add a step to the CI/CD pipeline that runs a dynamic code analysis tool during the pipeline execution.
  B. Add a step to the CI/CD pipeline that runs a static code analysis tool during the pipeline execution.
  C. Use only software modules that are written by the internal team.
  D. Add a step to the CI/CD pipeline to modify the release plan so that updated versions of the software are made available more often.
  E. Ensure that the code repository server has enabled drive encryption and stores the keys on a Trusted Platform Module or Hardware Security Module.
  A. Add a step to the CI/CD pipeline that runs a dynamic code analysis tool during the pipeline execution.
  B. Add a step to the CI/CD pipeline that runs a static code analysis tool during the pipeline execution.

  Adding a step to the CI/CD pipeline that runs a dynamic code analysis tool and a static code analysis tool during the pipeline execution helps make the security of an application a more integral part of the software development lifecycle. Dynamic code analysis tools search for coding errors and vulnerabilities while the application is running, while static code analysis tools scan the source code for potential errors and vulnerabilities. This ensures that any security issues are identified and addressed before the application is deployed. Additionally, using automated tools helps to reduce the amount of manual effort required for security testing and can reduce the risk of security flaws being introduced.
