Multicloud architectures use two or more IaaS providers (e.g., AWS + Azure + GCP) to distribute workloads, increase redundancy, and reduce single points of failure. Security+ SY0-701 emphasizes multicloud strategies for enhancing:
Resilience
Availability
Fault tolerance
Geographic redundancy
Vendor independence
The question specifies:
Critical VMs
Hosted across different IaaS providers
Still maintained by internal application owners
This perfectly matches a multicloud deployment, where organizations maintain control over VM configuration while leveraging multiple cloud vendors for resilience.
SaaS provider diversity (B) applies to application services, not internally managed VMs.
On-prem load balancing (C) does not involve cloud providers.
Corporate-owned off-site locations (D) refer to DR sites, not multi-vendor cloud hosting.
Thus, A: Multicloud architectures is the correct answer.
