NO.15 –
A developer is creating an application where each service uses a different operating system. The application components need to be isolated but must have the ability to communicate with each other.
Drag and drop the entries from the left into the order on the right to create a Dockerfile that will accomplish this goal.

NO.16 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-active

active

passive

NO.17 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 pipeline must be started manually after the code repository is updated.

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.

NO.18 Which interface is most commonly used to integrate logging, monitoring, and alerting applications into your CI/ CD pipeline?

AMQP

SNMP

SSH

REST

NO.19 Which two elements help to secure your API keys? (Choose two.)

ramdomness

SHA1

triple AES

rotation

dictionary

NO.20 Refer to the exhibit.

An application for data storing and processing has been created. The application is time-sensitive and manages confidential data AppDynamics identifies error transactions within a distributed application.
Which action will help resolve the errors?

Scale out the node horizontally

Drill down to investigate and identify the errors

Rewrite the SQL query identified in the transaction to be more efficient

NO.21 A DevOps engineer must build a Docker image to containerize an application. Then the image must be pushed to a repository on Docker Hub in a CI/CD pipeline using GitHub Actions.
Which approach securely encrypts the Docker Hub access token as an environment variable within the CI/CD pipeline?

Store the access token in an environment file in the repository

Store the access token with GitHub encrypted secrets

Store the access token with GitHub environment variables

Hard code the access token in the repository with Base64 encoding

NO.22 Refer to the exhibit.

The exhibit shows the output of an Ansible task that prints the contents of the show_ip_int_brief variable that was registered in a different task in the playbook.
Which expression is used to print the output of the command without its header row?

show_ip_int_brief[‘stdout_lines’][0][1:]

show_ip_int_brief[‘stdout_lines’]

show_ip_int_brief[‘stdout_lines’][1:]

show_ip_int_brief[‘stdout_lines’][0]

NO.23 How long analysis systems such as Elasticsearch, Logstash, and Kibana Stack handle ingesting unstructured logs from different devices in various formats?

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

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.

All different message formats are parsed separately using custom filters, and the resulting structured data is stored for later analysis.

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.

NO.24 To make logging searches more efficient and useful in Kibana, an Administrator wants to implement index patterns around the hostname of some software systems. Where should this be configured?

Configure a new JSON object in Kibana.

Create a search index in Logstash.

Create an index pattern in Kibana.

Create a time filter on Kibana to look at time only.

NO.25 A developer has created a deployment that should launch a pod to run their database service. The pod should launch with a metadata name of “Cisco-DB,” and the developer has added it to the “Cisco” namespace in their deployment.
Which Kubernetes command confirms that the service is running and usable?

kubectl -n Cisco get services | grep “Cisco-DB”

kubectl -n Cisco get pods | grep “Cisco-DB”

kubectl get pods | grep “Cisco-DB”

kubectl -n Cisco get service | grep “Cisco-DB”

NO.26 Which approach must be used to integrate DevOps practices into the team structure in an existing organization?

Create a team that can deliver all the stages with active cooperation between the team members

Create a team for each stage with structured communication channels

Create a team that can deliver all the stages with well-defined roles and a communication structure between team members

Create a team for each stage with active cooperation between the teams

NO.27 The E-commerce application is being monitored using AppDynamics. AppDynamics has noticed that the application response has degraded and has identified some thread contention that might be the cause of the delays.
Where in the interface does AppDynamics bring this to your attention?

Code Deadlock section of the Event List

Potential Issues section of an individual transaction

Slow Calls and Errors tab of the application

Transaction Score graph of a business transaction

NO.28 What is the purpose of using a build tool in software development?

It complies source code into binaries and executables.

It provides a way to edit source code using a graphical interface.

It is a manual process that is followed to build software.

It tracks bugs and incidents in a built application.

NO.29 Drag and drop the operations from the left into the correct order on the right when using CI/CD, assuming that there are no failures or conflicts.

NO.30 A DevOps engineer must validate the working state of the network before implementing a CI/CD pipeline model. Which configuration management tool is designed to accomplish this?
