Free Practice Questions for CompTIA 220-1201 Exam

Virtualization is the most suitable solution for maintaining a legacy application that is currently running on multiple physical servers. According to CompTIA Core 1 (220-1201) virtualization concepts, virtualization allows physical servers to be consolidated into virtual machines (VMs) that run on a single or reduced number of physical hosts while preserving the original operating systems and application environments.

Legacy applications often rely on older operating systems, specific hardware configurations, or outdated dependencies. Virtualization enables the organization to encapsulate the legacy environment, reducing hardware dependency and simplifying maintenance until the application can be fully retired. This approach also lowers power consumption, hardware costs, and physical space requirements while improving manageability and backup options.

A SAN (Storage Area Network) provides shared storage but does not address application hosting or server consolidation. FaaS (Function as a Service) is a cloud-native, event-driven computing model that requires application redesign and is unsuitable for legacy systems. A configuration management platform is used to manage and automate system configurations but does not replace physical servers or host applications.

CompTIA highlights virtualization as a key strategy for supporting legacy systems, improving flexibility, and extending the lifespan of applications during transition periods.
