A company has experienced serious growth and the hosted applications are getting more and more hits. Based on the increased work load, applications have started to show signs of reduced performance, which is affecting the user experience.
Which two server metrics should be tracked to ensure that the customer experience remains within acceptable limits? (Choose two.)
-
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.
As a department starts following NetDevOps principles, how should the network monitoring strategy be updated to provide more visibility into the user experience?
Drag and drop the tools from the left onto the tools function on the right Not all options are used.
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?
Fill in the blank to complete the statement.
A user wants a Kubernetes deployment to run three separate pods of a web application at one time. In the deployment YAML, the user must configure the___________field in the________subsection.
Drag and drop the code from the bottom onto the box where the code is missing to create a Terraform configuration that builds the network environment for a multitier software application. More EPG, Contract, and Filter definitions have been removed from the code.
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?
When static routes are added to a router in a network using a CI/CD pipeline, an Ansible playbook is used to make these changes. Which steps must be added to the pipeline to validate that the changes have the intended effect on the traffic flow?
What is the impact of using the Drone.io CI/CD tool on the local installation step?
An application is being built to collect and display telemetry streaming data. Drag and drop the elements of this stack from the left onto the correct functions on the right.
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?
Refer to the exhibit.
The IT team is creating a new design for a logging system. The system must be able to collect logs from different components of the infrastructure using the SNMP protocol. When the data is collected it will need to be presented in a graphical UI to the NOC team.
What is the architectural component that needs to be placed in the unlabeled box to complete this design?
Refer to the exhibit.
A developer is creating a script to test APIs. The Cisco Webex API and a CI/CD pipeline are tested to ensure that the script runs without problems. The script is executed without issues locally, but the CI/CD system returns the error shown. What is the problem with the script?
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.
Refer to the exhibit.
How should the Jenkins job be troubleshooted based on the error provided?
ConfigMap keys have been mapped to different file names using the volumes.configMap.items field. What is the result if a wrong ConfigMap key is specified?
Refer to the exhibit.
The snippet contains the JSON string that will be sent to the Prometheus AlertManager to silence an alert. AlertManager accepts only the content type of application 'json'' Which Python code correctly sends an API call to perform action?
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?
Drag and drop the code snippets from the bottom onto the boxes in the code in the Ansible playbook to restart multiple services in the correct sequence Not all options are used
Refer to the exhibit A DevOps engineer is responsible for monitoring a mission-critical app During normal operations, when opening the application dashboard, it has been noticed that Ecom-Tier1 suddenly turns partially red Which action must be taken to address the Ecom-Tier1 turning red?
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.
An application communicates with multiple third-party services that use API keys When stress testing the system, developers must change the URLs of the third-party services The application must run on port 5000. but the developers must be able to change the port at runtime if required Which configuration management approach simplifies the development workflow and reduces the configuration changes?
Which Docker command is used to start an interactive Bash shell in a running container named “test”?
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?
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?
What is as responsibility for teams running private cloud servers that is less of a concern when running in the public cloud?
A CI/CD pipeline that builds infrastructure components using Terraform must be designed. A step in the pipeline is needed that checks for errors in any of the .tf files in the working directory. It also checks the existing state of the defined infrastructure.
Which command does the pipeline run to accomplish this goal?
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?
When DevOps practices are integrated into an existing organization, which two characteristics are positive indicators of DevOps maturity? (Choose two.)
An engineer is developing a script that must call an API using a static Bearer token Which solution securely protects the credentials from being retrievable from the source code?
A)
A)
B)
C)
D)
A precheck validation is being designed for the network state in a Cl/CD pipeline This design requires:
• the CI/CD pipeline to spin up test instances.
• instances must be used to validate changes.
• changes must be validated prior to a continuous deployment workflow, and
• then push the changes to production
How should the pipeline target the required environment?
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?
