A DevOps engineer is supporting a containerized application with multiple components running across the Kubernetes cluster. Metrics from the container (CPU and memory) and application (requests per second and heap size) are being collected by Prometheus and displayed with Grafan
a. Users report transaction timeout problems with the application, but the metric graphs all look within normal levels.
Which type of failure would prevent the engineer from seeing the problem using the captured metrics?
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?
Refer to the Exhibit.
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?
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 webhook is basically a callback URL that is triggered when certain events occur, such as a code commit. If the webhook call from the code repository does not reach the CI server, then the pipeline will not start. According to the Cisco Implementing DevOps Solutions and Practices using Cisco Platforms (DEVOPS) Study Manual, 'A webhook is a web-based feature that enables a remote service to communicate with a local service, usually through a web server. Webhooks are used to trigger an action when a specific event occurs, usually in a remote service or application.'
What is as responsibility for teams running private cloud servers that is less of a concern when running in the public cloud?
The responsibility of credentials management is less of a concern when running in the public cloud. This is because the public cloud provider typically manages the credentials and handles authentication and authorization for the cloud services. In a private cloud environment, the organization must manage the credentials themselves, as well as authentication and authorization for the cloud services.
