   A company's CI/CD pipeline deploys a new version of their application to a staging environment. The pipeline runs automated tests, but the team has noticed that some issues only appear in production under high load. They want to add automated validation in the production environment after deployment, but they are concerned about the risk of a bad deployment affecting real users. They also want to automatically roll back if the validation fails. Which strategy best balances the need for production validation with risk mitigation?

   • ADeploy to a small subset of production servers (canary deployment), run automated health checks and synthetic transactions, and automatically roll back if they fail.
   • BDeploy to production but disable the new version for all users and only enable it after a manual review by the operations team.
   • CDeploy to all production servers at once and rely on the monitoring system to alert the team if there are issues, then manually roll back.
   • DRun the automated tests in the staging environment only and deploy to production if they pass, without any post-deployment validation.

   A company is planning to automate its cloud environment. They have a mix of legacy VMs and modern containerized applications. The team wants to use a single tool to manage both the VMs and the containers. They are evaluating Ansible and Kubernetes. Which statement accurately reflects the capabilities of these tools in this context?

   • AAnsible is a container orchestrator and can replace Kubernetes for managing containerized applications.
   • BNeither tool can manage both VMs and containers, so a combination of tools is always required.
   • CKubernetes can manage both VMs and containers, making it a better choice than Ansible for this scenario.
   • DAnsible can manage both VMs and containers, but Kubernetes is specifically designed for container orchestration and provides more advanced scaling and self-healing features.

   A company has a fleet of 200 Linux VMs in the cloud. The security team has mandated that all VMs must have a specific security agent installed and a particular set of firewall rules applied. The operations team wants to ensure that any new VM automatically receives these configurations and that any manual changes to these settings are corrected. Which tool is most appropriate for this ongoing task?

   • AAn Infrastructure as Code template that is used only when creating new VMs.
   • BA configuration management tool that defines the desired state of the security agent and firewall rules and periodically enforces it on all VMs.
   • CA shell script that is run once by an administrator on each VM to install the agent and apply the firewall rules.
   • DAn orchestration tool that coordinates the deployment of a new application across the VM fleet.

   A company uses a cloud-based ticketing system (e.g., Jira) and a cloud monitoring platform. They want to automatically create a high-priority ticket in the ticketing system whenever a specific critical alert is triggered. Which approach is the most direct and efficient?

   • ASet up a CI/CD pipeline that creates a ticket in the ticketing system every time code is deployed.
   • BConfigure the monitoring platform to send an HTTP POST request to the ticketing system's REST API to create a ticket.
   • CHave an on-call engineer manually create a ticket in the ticketing system when they receive the alert.
   • DUse a configuration management tool to install a plugin on the monitoring server that connects to the ticketing system.
