Abel, a cloud architect, uses container technology to deploy applications/software including all its dependencies, such as libraries and configuration files, binaries, and other resources that run…

Question

Options

• ATier-1: Developer machines
• BTier-4: Orchestrators
• CTier-3: Registries
• DTier-2: Testing and accreditation systems

• A
  12% (6)
• B
  6% (3)
• C
  2% (1)
• D
  80% (41)

Explanation

Explanation

Option D is correct because Tier-2 (Testing and Accreditation Systems) is specifically responsible for verifying and validating image contents, signing images, and accrediting them before they are approved and forwarded to registries - this is the quality assurance and security validation stage of the container pipeline.

Why the other options are wrong:

• Option A (Tier-1: Developer Machines) is where developers initially build and create container images, not where validation and signing occur.
• Option B (Tier-4: Orchestrators) is where container deployment, scaling, and management take place (e.g., Kubernetes), which comes after images are already in registries.
• Option C (Tier-3: Registries) is where images are stored and distributed after they have already been signed and validated - Abel hasn't reached this stage yet.

Memory Tip

Think of the flow as an assembly line: Build → Test/Sign → Store → Orchestrate → Run. Since Abel is signing and validating (quality control), he's at Stage 2 - just like a factory inspector checks products before they go to the warehouse (registry). If it involves security checks and signing, it's Tier-2.
