QuestionQ42

Security Engineering

A company is adopting a microservices architecture to remediate vulnerabilities quickly and deploy to production. All microservices run on the same Linux platform. Updating the base OS before code deployment consumed significant time. What should the company do to make this process more efficient?

  • 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.
Explanation

A patched golden image provides a reusable, standardized Linux baseline, so OS updates and hardening are baked once and newly deployed workloads start from the current image rather than repeatedly updating the base OS. Infrastructure-as-code automation can make creating and deploying those images repeatable. Immutable infrastructure practices replace workloads with instances built from updated images instead of applying in-place production updates.
