Take a Leap Forward in Your Career by Earning Cisco 300-910

Cisco 300-910 certification exam is designed to test the candidate’s knowledge of DevOps practices, automation tools, and Cisco platforms. 300-910 exam covers a range of topics, including containerization, cloud infrastructure, automation, and network programmability. 300-910 exam is also designed to test the candidate’s ability to work with various Cisco platforms, such as Cisco Application Centric Infrastructure (ACI), Cisco CloudCenter, and Cisco DNA Center.

Q29. What is a capability of node-level logging in Kubernetes?

Using the Kubernetes JSON logging driver enables log persistence

Output that is written to stdin is retrieved by using kubectl

Output that is written to stderr is not logged or retrievable by using kubectl

Using the local logging driver of Docker enables log persistence

Q30. AppDynamics is being used to monitor your distributed Python application. Each individual container of the application is instrumented with an AppD agent. Which two configuration variables uniquely determine the module being monitored? (Choose two.)

Q31. Refer to the exhibit. How should the Jenkins job be troubleshooted based on the error provided?

Verify what the responding file created.

Update pip.

Install dependencies.

Place the code in a container and run the job again.

Q32. Refer to the exhibit.

What is the reason for this error message?

The required dependencies for the urllib3 module are not installed.

The requests module is not installed.

The required dependencies for the requests module are not installed.

The site-packages directory has been corrupted.

Q33. Configuration changes to the production network devices are performed by a CI/CD pipeline. The code repository and the CI tool are running on separate servers. Some configuration changes are pushed to the code repository, but the pipeline did not start.
Why did the pipeline fail to start?

The CI server was not configured as a Git remote for the repository.

The webhook call from the code repository did not reach the CI server.

Configuration changes must be sent to the pipeline, which then updates the repository.

The pipeline must be started manually after the code repository is updated.

A webhook is basically a callback URL that is triggered when certain events occur, such as a code commit. If the webhook call from the code repository does not reach the CI server, then the pipeline will not start. 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.”

Q34. Refer to the exhibit.

What is causing the requests code to fail?

Rython3 is not compatible with requests.

The requests library is not imported.

The requests library is not installed.

The requests coming into stdin fail because device_ip cannot be parsed.

Q35. Refer to the exhibit.

What is the user doing with Drone in this automated test?

testing Alpine Linux versus Ubuntu Linux

testing a PostgreSQL DB against multiple architectures

testing only the amd64 architecture

testing PostgreSQL deployment in an Alpine Linux VM

Q36. A DevOps engineer has built a new container and must open port 8080 for intercontainer communication. Which command must be added in a Dockerfile to accomplish this goal?

EXPOSE 8080

FIREWALL ADD-PORT 8080

PORT 8080

OPEN PORT 8080

Q37. A new banking application is being developed as the main currency exchange resource for all the customers on a global scale. The application must comply with the security based on the deployed region. Therefore, the CI/CD pipeline must be created with the highest security possible.
Which approach accomplishes this goal?

Use the same passwords across the entire CI/CD pipeline

Give the accounts used in the CI/CD pipeline full administrative rights to all applications

Ensure that secrets are not inadvertently passed on during builds for pull requests via CI/CD pipeline

Never use one-time passwords in CI/CD pipeline

Q38. A DevOps engineering wants to build an application implementation based on the CI/CD pipeline model.
Which service should be used to provide hosted continuous service for open and private projects?

Ansible

pyATS

Genie CLI

Travis CI

Q39. A developer wants to deploy a highly available web server cluster and decides to put a load balancer in front of multiple clustered nodes that run the same web service. The goal is for the load balancer to take in users and distribute the load across the whole cluster.
What kind of high-availability configuration is the developer running?

active

passive

active-passive

active-active

An active-active high-availability configuration is when the load balancer is used to distribute the load across the whole cluster of nodes that are running the same web service. In this configuration, all of the nodes are active and available to serve requests at any given time. This is in contrast to an active-passive configuration, where only one node is active and the other nodes are passive and serve as backups in case of a failure.

Q40. DRAG DROP
Construct an Ansible script to gather information about target routers and then use it to apply no ip redirects to every interface on each device. Drag and drop the code from the bottom onto the correct location in the exhibit to complete the tasks section of the Ansible playbook so that it accomplishes your goal.
Select and Place:

Section: Automating Infrastructure

Q41. Which Dockerfile produces an efficient image rebuild when the exposed port Python dependency, or MyApp source code is modified?
A)

B)

C)

D)

Option B

Option A

Option C

Option D

Q42. Refer to the exhibit.

The JSON object represents a single entry on a centralized log server, but log data cannot be processed because of the format.
What causes the issue?

The process name in the message must be parsed into a field

A hostgroup must be defined

The priority of the message must be to the server

The “_type” must represent the process type

Q43. A developer is containerizing an application. The container “devnetprotf’ has been run in detached mode to output the container ID with the command

Which command must be used to start an interactive Bash shell the running container?

docker exec -it 1b487caec32a /bin/bash

docker exec -it devnetprod /bin/bash

doctor run -it devnetprod /bin/bash

docker run -it 1b48caec32a /bin/bash

Q44. A three-tier web application must be moved to containers. A webserver is already in place, and the middleware container can talk to a central database server. The hostname of the database server is known, but the name of the middleware server must be provided to the webserver.

Docker Swarm

Dynamic Host Configuration Protocol

Docker Compose

Docker Service discovery daemon
