CompTIA Server+ (SK0-005)Server AdministrationEasy
A server administrator is consolidating several older physical servers onto a new, powerful hardware platform. The goal is to maximize hardware utilization and simplify management while ensuring each application runs in its own isolated environment. Which technology is best suited for this scenario?
- AServer virtualization.
- BContainer orchestration.
- CHigh-performance computing (HPC) clusters.
- DBare-metal server deployment.
Show answer & explanationAnswer & explanation
Correct answer: A. Server virtualization.
Server virtualization allows multiple virtual machines (VMs) to run on a single physical server, each with its own isolated OS and applications. This maximizes hardware utilization, simplifies management, and provides isolation, directly addressing the scenario's requirements.
Why the other options are wrong
- B. Container orchestration manages containers, which are lighter than VMs. While offering isolation, the scenario emphasizes consolidating 'servers' and 'OS' isolation, which typically points to VMs for full OS-level separation.
- C. HPC clusters are designed for parallel processing of complex computations, not primarily for consolidating diverse applications into isolated environments to maximize hardware utilization.
- D. Bare-metal deployment involves installing an OS directly on physical hardware, which does not maximize utilization through consolidation or provide isolated environments for multiple applications on a single physical server.
Server Virtualization
The process of dividing a physical server into multiple isolated virtual servers (virtual machines), each capable of running its own operating system and applications.
- Maximizes hardware utilization.
- Provides isolation between applications/OSes.
- Simplifies server provisioning and management.
