Question 1

Question 2

Question 3

An application has been designed based on microservices. The application is deployed on Kubernetes using multiple pods that share the same IP address. Each pod is responsible for a service in the application.

Which command validates the success of the application deployment?

A kubectl get pods -o wide -w
B kubectl rollout status deployment
C kubectl describe pods/
D kubectl rollout history deployment

Question 4

A developer is creating an application based on microservices. The application will be used as a central repository for all company's documents. One of the microservices in the application will perform image processing. This microservice must autoscale to meet the current load and avoid down time.

Which metric must be used to trigger autoscaling events?

A network
B CPU/GPU
C disk I/O
D memory

Question 5

DRAG DROP

Drag and drop the scenarios from the left onto the cloud strategy categories on the right.

Question 6

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

A Using the Kubernetes JSON logging driver enables log persistence
B Output that is written to stdin is retrieved by using kubectl
C Output that is written to stderr is not logged or retrievable by using kubectl
D Using the local logging driver of Docker enables log persistence

Question 7

Which Dockerfile yields the most predictable builds?

A
B
C
D

Question 8

What is the purpose of using sysprep when developing a Microsoft Windows-based golden image process?

A prepares a new host to accept a hard drive image built on another machine
B removes all host-specific information and components from the local machine
C installs all the latest security patches and OS updates to the local machine
D writes the local hard drive image to an ISO file that can be deployed to another machine

Question 9

An IT department needs to deploy a new application named ‘Entfin434772390’ across the entire enterprise. The deployment must gradually transfer user traffic from an on older and nearly identical version of the application named ‘Entfin02754932l’. Both versions of the application are running in the production environment.

Which release strategy should be used by the IT department?

A agile
B canary
C rollbacks
D blue/green

Question 10

DRAG DROP

Drag and drop the code from the bottom onto the box where the code is missing to post a message to a Cisco Webex space. Not all options are used.

Question 11

DRAG DROP

Drag and drop the tools from the left onto the tool's function on the right. Not all options are used.

Question 12

Question 14

Question 15

Question 16

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

A
B
C
D

Question 17

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?

A Give the accounts used in the CI/CD pipeline full administrative rights to all applications
B Use the same passwords across the entire CI/CD pipeline
C Ensure that secrets are not inadvertently passed on during builds for pull requests via CI/CD pipeline
D Never use one-time passwords in CI/CD pipeline

Question 18

An IT team plans to deploy a new service built on top of an existing service. The capacity needed for the new service is difficult to estimate because the demand for the new service is undetermined. The team has these deployment requirements:
• A subset of the users of the original service must be migrated to the new service based on their profile
• The new service must be rolled back easily if capacity exceeds estimates

Which deployment strategy must be used?

A rolling
B blue/green
C geolocation
D canary

Question 19

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?

A Ansible
B pyATS
C Genie CLI
D Travis CI

Question 20

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?

A EXPOSE 8080
B FIREWALL ADD-PORT 8080
C PORT 8080
D OPEN PORT 8080

Question 21

Which two actions help limit the attack surface of your Docker container? (Choose two.)

A Run only a single service in each container.
B Run all services in a single image.
C Use version tags for base images and dependencies.
D Use Kali Linux as a base image.
E Download images over HTTPS supporting sites.

Question 22

A DevOps engineer has built a container to host a web-server and it must run as an executable. Which command must be configured in a Dockerfile to accomplish this goal?

A ENTRYPOINT <usr/sbin/apache2ctl>
B ENTRYPOINT ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]
C ENTRYPOINT ["BACKGROUND", "-D", "/usr/sbin/apache2ctl"]
D ENTRYPOINT {usr/sbin/apache2ctl}

Question 23
