Physical server dedicated to a single tenant
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Virtual Machines: Provides virtualized hardware allowing full control over the operating system and software stack.
Correct matches: Virtual Machines provide virtualized hardware; Containers package code and dependencies; Serverless Functions run code on demand; Bare Metal offers dedicated hardware. Common confusions include mixing containers with VMs and serverless with bare metal.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Virtual Machines: Provides virtualized hardware allowing full control over the operating system and software stack.
Why this is correct
Correct: Virtual Machines (VMs) offer a virtualized environment with full OS control.
Containers: Packages code and dependencies to run consistently across environments, sharing the host OS kernel.
Why this is correct
Correct: Containers bundle application code and dependencies, sharing the host OS kernel for efficiency.
Serverless Functions: Executes code in response to events without provisioning or managing servers.
Why this is correct
Correct: Serverless Functions run code on demand, abstracting server management.
Bare Metal Servers: Provides dedicated physical servers with no hypervisor, giving raw hardware access.
Why this is correct
Correct: Bare Metal servers offer dedicated hardware without virtualization layers.
Virtual Machines: Packages code and dependencies to run consistently across environments.
Why it's wrong here
Incorrect: This describes Containers, not Virtual Machines. VMs virtualize hardware, not just package code.
Bare Metal: Executes code in response to events without server management.
Why it's wrong here
Incorrect: This describes Serverless Functions, not Bare Metal. Bare Metal involves dedicated physical servers.
