Cisco 300-910 Online Questions & Answers

• Question 81:

  Which approach must be used to integrate DevOps practices into the team structure in an existing organization?

  A. Create a team that can deliver all the stages with active cooperation between the team members
  B. Create a team that can deliver all the stages with well-defined roles and a communication structure between team members
  C. Create a team for each stage with structured communication channels
  D. Create a team for each stage with active cooperation between the teams
  A. Create a team that can deliver all the stages with active cooperation between the team members

• Question 82:

  As a department starts following NetDevOps principles, how should the network monitoring strategy be updated to provide more visibility into the user experience?

  A. Leverage machine learning tools to more quickly identify problems m syslog and SNMP data
  B. Update tools to pull or stream monitoring metrics from APIs instead of using legacy protocols
  C. Identify and capture the key performance indicators that describe the state of the network
  D. Identify and fix network issues faster by leveraging streaming telemetry from network devices
  B. Update tools to pull or stream monitoring metrics from APIs instead of using legacy protocols

  ---

  Updating tools to pull or stream monitoring metrics from APIs instead of using legacy protocols is an important part of a NetDevOps strategy, as it allows for more efficient and automated data collection, as well as better visibility into the user experience. APIs for network monitoring are becoming increasingly common, as they allow for a more direct connection to the devices themselves, and can provide access to more detailed and specific metrics. Cisco's DevOps Solutions and Practices Guide recommends leveraging APIs to monitor the user experience, as they can provide access to more specific metrics and can be integrated with other monitoring tools.

• Question 83:

  A user wants to deploy a new service to a Kubernetes cluster. Which two commands accomplish this goal? (Choose two.)

  A. Apply
  B. Install
  C. Deploy
  D. Create
  E. Expose
  A. Apply
  E. Expose

• Question 84:

  How does eliminating hardcoded or default passwords help to secure an environment?

  A. helps by enforcing your password in a repository and storing it in a secure vault
  B. helps to manage passwords centrally
  C. helps penetration testing team to focus on other issues more efficiently
  D. helps by removing back doors in your environments
  A. helps by enforcing your password in a repository and storing it in a secure vault

• Question 85:

  Which Docker command is used to start an interactive Bash shell in a running container named "test"?

  A. docker attach -it test /bin/bash
  B. docker run -it test /bin/bash
  C. docker exec -it test /bin/bash
  D. docker run test /bin/bash
  C. docker exec -it test /bin/bash

• Question 86:

  Refer to the exhibit.

  

  The IT team is creating a new design for a logging system. The system must be able to collect logs from different components of the infrastructure using the SNMP protocol. When the data is collected it will need to be presented in a graphical UI to the NOC team.

  What is the architectural component that needs to be placed in the unlabeled box to complete this design?

  A. message queue
  B. web server
  C. log parser D. time-series database
  C. log parser D. time-series database

  ---

  A log parser is a software component that is used to collect and parse log data from various sources, such as infrastructure devices, applications, and services. It is responsible for collecting log data from the various sources and then mapping it to a specific format that can be easily consumed and interpreted by the NOC team. The log parser can also be used to filter out irrelevant data and store the processed data in a time- series database. This data can then be used by the NOC team to generate visualizations and reports, which will help them identify and address any issues within the infrastructure.

• Question 87:

  When DevOps practices are integrated into an existing organization, which two characteristics are positive indicators of DevOps maturity? (Choose two.)

  A. mean time between success
  B. mean time to recover
  C. cone testing
  D. change lead time
  E. age of codebase
  B. mean time to recover
  D. change lead time

  ---

  Change lead time is the amount of time it takes for a proposed change to go from the idea phase to being fully deployed in production. This metric can be used to measure the speed and efficiency with which changes are implemented, which is often indicative of an organization's DevOps maturity. Mean time to recover (MTTR) is the average amount of time it takes to restore a service or application to its working state when an issue arises. MTTR is an important metric for measuring the resilience of an organization's infrastructure, and is another indicator of DevOps maturity.

• Question 88:

  A precheck validation is being designed for the network state in a Cl/CD pipeline This design requires:

  1.

  the CI/CD pipeline to spin up test instances.

  2.

  instances must be used to validate changes.

  3.

  changes must be validated prior to a continuous deployment workflow, and

  4.

  then push the changes to production

  How should the pipeline target the required environment?

  A. Use separate CI servers for each environment
  B. Use different pipelines for each environment
  C. Use separate Git repositories for each environment
  D. Use different inventory files for each environment
  D. Use different inventory files for each environment

• Question 89:

  Which two elements help to secure your API keys? (Choose two.)

  A. ramdomness
  B. SHA1
  C. triple AES
  D. rotation
  E. dictionary
  A. ramdomness
  C. triple AES

• Question 90:

  Refer to the exhibit.
