CompTIA SecurityX (CAS-005) — Question 81

A company is adopting microservice architecture in order to quickly remediate vulnerabilities and deploy to production. All of the microservices run on the same Linux platform. Significant time was spent updating the base OS before deploying code. Which of the following should the company do to make the process efficient?

Answer options

• A. Use Terraform scripts while creating golden images.
• B. Create a cron job to run apt-update every 30 days.
• C. Use snapshots to deploy code to existing compute instances.
• D. Deploy a centralized update server.

Correct answer: A

Explanation

The correct answer is A because using Terraform scripts to create golden images allows for consistent and rapid deployment of updated base OS configurations, streamlining the process. Option B is less efficient as updating every 30 days does not address immediate vulnerabilities. Option C, while useful for deployment, does not directly solve the base OS update issue. Option D could help but may introduce complexity without addressing the need for efficient base OS updates.
