Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  The company wants to pay less for cloud services.

  Why it's wrong here

  Managed private cloud is significantly more expensive than public cloud because you pay for dedicated physical servers, isolated storage, and separate network appliances without sharing the cost across multiple tenants. Public cloud's multi-tenant model spreads infrastructure expenses across many customers, lowering unit costs, whereas private cloud's exclusivity eliminates those economies of scale. Cost reduction is therefore a reason to choose multi-tenant public cloud, not a managed private solution.

• ✓

  The company has regulatory requirements that mandate physically dedicated (single-tenant) infrastructure or strict hardware-level isolation.

  Why this is correct

  Managed private cloud provisions physically dedicated, single-tenant hardware that runs your workloads, while the cloud provider handles operations such as patching, monitoring, and availability. This is essential for regulated industries—like defense, certain financial sectors, or healthcare in specific jurisdictions—where compliance frameworks require hardware-level isolation that logical hypervisor separation cannot satisfy. It balances the operational flexibility of a cloud service with the auditability and separation of dedicated infrastructure.

• ✗

  The company wants the fastest possible internet speeds for their applications.

  Why it's wrong here

  Internet speed to end users depends on network architecture, peering, bandwidth, and location—not on whether infrastructure is private or public. In fact, public clouds typically operate massive, globally redundant backbones with advanced Anycast and edge caching that can deliver faster, more consistent connectivity than a single managed private cloud deployment. Choosing a managed private cloud for speed would be a network design mistake; regulatory or security requirements are the correct drivers.

• ✗

  The company has fewer than 10 employees and doesn't need multi-tenant scale.

  Why it's wrong here

  Company size has no bearing on cloud deployment model. A 10-person company can effectively leverage public cloud's multi-tenant infrastructure, where tenants are isolated logically but share physical resources; conversely, a large enterprise may not need a managed private cloud if compliance permits multi-tenant. The choice is driven by data sensitivity and regulatory mandates, not by employee count or perceived multi-tenant scale requirements.
