Question 1

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

Amean time between success

Bmean time to recover

Ccone testing

Dchange lead time

Eage of codebase

Answer : B, D

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 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?

Asoak testing

Bunit testing

Cload testing

Dvolume testing

Answer : B

Question 3

Which step must be taken to enable centralized logging in a Kubernetes environment?

ANo steps need to be taken. The master node automatically aggregates logs from all worker nodes and stores them on the specified persistent volume.

BCreate a CustomResourceDefinition in each deployment that specifies the IP or names the log collector.

CDeploy a sidecar node that aggregates logs from the entire cluster.

DCreate a DaemonSet that deploys a container with a logging agent on every node in the cluster.

Answer : D

To enable centralized logging in a Kubernetes environment, you must create a DaemonSet that deploys a container with a logging agent on every node in the cluster. This allows all of the logs from each node to be collected in one place, allowing for easier analysis and management. Reference: Kubernetes Documentation, Logging Architecture.

Question 4

A new version of an application is being released by creating a separate instance of the application that is running the new code. Only a small portion of the user base will be directed to the new instance until that version has been proven stable. Which deployment strategy is this example of?

Arecreate

Bblue/green

Crolling

Dcanary

Answer : D

Question 5

Refer to the exhibit.

An organization has issues with code-based failures after implementing a CI/CD pipeline to automate the builds and deployment phases of an application.

Which action must be added to the pipeline, after the application is deployed in the staging environment to minimize failures and to ensure a successful continuous deployment?

ARestructuring and monitoring tests must be run after it is promoted to production

BRestructuring and monitoring tests must be run before it is promoted to production

CFunctional and nonfunctional tests must be run after it is promoted to production

DFunctional and nonfunctional tests must be run before it is promoted to production

Answer : D

According to Cisco's Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, it is important to run functional and non-functional tests before promoting the application to production. This is essential in order to identify and address any issues that could cause code-based failures. Additionally, a pipeline should include automated tests that can be used to verify that processes are running correctly. By running these tests before promoting to production, you can ensure that any potential issues are identified and addressed before the application is released.

Question 6

What is a practice of infrastructure as code?

AUse multiple version control systems

BDocument as much as possible

CConfigure the deployment consistently

DTest, integrate, and deploy once a day

Answer : C

Question 7

Refer to the exhibit.
