Which action should you take?

Choose only one option

Define clear Git workflow policies and branching strategies to manage changes effectively.

Implement automated synchronization mechanisms to ensure consistency between Git repositories and the deployed environment.

Provide comprehensive training and support to team members on GitOps principles and practices.

All of the above.

Question 2: Your organization is adopting a multi-cloud strategy, aiming for cost optimization and vendor flexibility. You are leading the IaC initiative. How do you ensure a consistent and manageable infrastructure across multiple cloud providers while maximizing cost efficiency?

Which action should you take?

Choose only one option

Develop a custom IaC framework that abstracts cloud-specific complexities and provides a unified interface for managing resources across different providers.

Leverage a cloud-agnostic IaC tool that supports multiple cloud providers and offers built-in cost optimization features.

Utilize a combination of cloud-specific IaC tools and a central orchestration layer to manage infrastructure provisioning and configuration across different clouds.

Implement a policy-as-code framework to enforce cost optimization best practices and governance across all cloud environments.

Question 3: You are tasked with implementing a secure software supply chain for your organization, ensuring that all software components and dependencies are free from vulnerabilities and malicious code. What key practices and tools do you incorporate into your software development and deployment processes?

Which action should you take?

Choose only one option

Implement a software bill of materials (SBOM) to track and manage all components and dependencies used in your applications.

Utilize software composition analysis (SCA) tools to scan for known vulnerabilities in open-source and third-party components.

Enforce strict access controls and code signing practices to prevent unauthorized modifications or tampering with software artifacts.

Implement a secure container registry to store and manage container images, ensuring they are scanned for vulnerabilities and signed before deployment.

Question 4: You've made a change to a Terraform configuration file, but after applying it, you realize it introduced an unintended side effect. How do you quickly and safely revert the change?

Which action should you take?

Choose only one option

Use Terraform's terraform destroy command to destroy the affected resources and then reapply the previous configuration.

Manually revert the change in the Terraform configuration file and then run terraform apply to apply the corrected configuration.

Utilize Terraform's state file to identify the specific changes made and then use terraform taint and terraform apply to force recreation of the affected resources.

Temporarily comment out the problematic part of the Terraform configuration and reapply it to see if the issue is resolved.

Question 5: You've deployed an application to multiple regions on AWS to improve performance and availability for users around the world. You now need a way to distribute traffic to the closest region for each user. What service would you use?

Which action should you take?

Choose only one option

AWS Global Accelerator

AWS CloudFront

AWS Route 53

AWS Elastic Load Balancing

Question 6: You are leading a team responsible for monitoring a critical production system with stringent Service Level Objectives (SLOs). How do you ensure that your monitoring strategy aligns with these SLOs and enables you to proactively identify and address potential risks?

Which action should you take?

Choose only one option

Define clear Service Level Indicators (SLIs) that directly reflect the user experience and align with the defined SLOs.

Implement real-time monitoring and alerting based on the SLIs, with thresholds and escalation procedures in place to trigger timely action when SLOs are at risk of being breached.

Conduct regular performance testing and capacity planning exercises to ensure that the system can handle expected workloads and maintain SLO compliance.

Continuously analyze monitoring data and identify trends or patterns that could indicate potential issues, allowing for proactive remediation before SLOs are impacted.
