TA-002-P Question #21: Real Exam Question with Answer & Explanation

Question

You have recently started a new job at a retailer as an engineer. As part of this new role, you have been tasked with evaluating multiple outages that occurred during peak shopping time during the holiday season. Your investigation found that the team is manually deploying new compute instances and configuring each compute instance manually. This has led to inconsistent configuration between each compute instance. How would you solve this using infrastructure as code?

Options

• AImplement a ticketing workflow that makes engineers submit a ticket before manually
• BImplement a checklist that engineers can follow when configuring compute instances
• CReplace the compute instance type with a larger version to reduce the number of
• DImplement a provisioning pipeline that deploys infrastructure configurations committed to

Explanation

To address inconsistent configurations caused by manual deployments, a ticketing workflow can formalize and control infrastructure changes, preparing for or enforcing infrastructure as code practices.

Common mistakes.

• B. Implementing a checklist for manual configuration still relies on human execution and does not guarantee consistency or address the root cause of manual deployment, which IAC aims to eliminate.
• C. Replacing instance types addresses performance or capacity, not the inconsistency in configuration or the manual deployment process.
• D. Implementing a provisioning pipeline is a direct application of Infrastructure as Code, which solves the problem but is a more specific technical implementation, while the ticketing workflow provides the overarching governance.
