In which scenario would a single-tenant model be preferred over a multi-tenant model?

Question

Options

• AWhen optimizing infrastructure for cost efficiency
• BWhen multiple organizations need to share cloud resources
• CWhen an organization requires strict data and security isolation
• DWhen enforcing user access policies across multiple teams

• A
  3% (1)
• B
  9% (3)
• C
  74% (25)
• D
  15% (5)

Explanation

Single-tenant architecture dedicates an entire infrastructure instance to one organization, making it the right choice when strict data isolation and security are non-negotiable - think regulated industries like healthcare (HIPAA) or finance (SOX), where tenant data must never share the same underlying resources.

Why the distractors are wrong:

• A is wrong because single-tenant is more expensive - you can't amortize infrastructure costs across many customers; multi-tenant wins on cost efficiency.
• B is wrong because sharing resources across organizations is the definition of multi-tenant, not single-tenant.
• D is wrong because access policies across teams are an identity/IAM concern, not a tenancy architecture concern - both models can enforce them.

Memory tip: Think of single-tenant as a private house (you own everything, no shared walls) vs. multi-tenant as an apartment building (cheaper, shared infrastructure, but neighbors exist). When the question mentions isolation, compliance, or dedicated resources, that's your signal to pick single-tenant.
