Question 1

What are two testing scenarios of the chaos engineering principle? (Choose two.)

A. unplugging a core switch device

B. maxing out CPU cores on an Elasticsearch cluster

C. executing routine in driver code to emulate I/O errors

D. blocking developers' building access

E. removing all users from a version control system

Correct Answer: A,B

Question 2

Refer to the Exhibit.

Refer to the exhibit A DevOps engineer must deploy two microservices The deployment must be installed in a new Kubernetes cluster. The microservices currently run in Docker and are managed by using the provided docker-compose yml file Drag and drop the steps from the left into order on the right to successfully deploy the microservices

Correct Answer:

Question 3

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?

A. Functional and nonfunctional tests must be run before it is promoted to production

B. Restructuring and monitoring tests must be run before it is promoted to production

C. Restructuring and monitoring tests must be run after it is promoted to production

D. Functional and nonfunctional tests must be run after it is promoted to production

Question 5

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

A. 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.

B. 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.

D. All devices that generate syslogs must use agents that process the local logs and transmit them in a specific format to the ELK Stack.

Question 6

Refer to the exhibit.

A development team is designing an application that will include multiple components and services. To streamline the process, CO/CD must be implemented.
Drag and drop the CI/CD pipeline stages from the left onto the targets on the right.

Correct Answer:

Question 7

Refer to the exhibit.

A distributed application contains data services that connect to databases via JDBC and to other remote services via HTTP. The overall response time is too long, and AppDynamics is used to investigate the root cause. From the application flow map, a specific data service running on Docker has been identified whose response time is over 10 seconds.
Which action resolves the issue?

A. Run the AccountProfileMySQL service in Kubernetes

B. Change from a JDBC call to a HTTP call to retrieve data faster

C. Verify if the Docker container running MySQL is limiting CPU utilization

D. Explore the JDBC queries looking for optimization opportunities

Correct Answer: D

Question 8

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?

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

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

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

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