CCNP Practice Question: Which two statements about NFV architecture and…
Which two statements about NFV architecture and components are true? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The NFV Infrastructure (NFVI) includes compute, storage, and networking resources that host VNFs.
NFV decouples network functions from dedicated hardware. The NFV Infrastructure includes compute, storage, and networking resources. VNFs run on top of the NFVI. The NFV MANO framework orchestrates and manages these components. Option A is correct because NFVI provides the virtualized resources. Option B is correct because VNFs are software implementations of network functions. Option C is incorrect because NFV does not require dedicated hardware per VNF; it relies on shared infrastructure. Option D is incorrect because VNFs are managed by the VNFM, not the VIM. Option E is incorrect because the NFV Orchestrator handles lifecycle management, not just resource allocation.
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 NFV Infrastructure (NFVI) includes compute, storage, and networking resources that host VNFs.
Why this is correct
Correct because the NFVI provides the virtualized resources (compute, storage, network) upon which VNFs are deployed.
- ✓
Virtual Network Functions (VNFs) are software implementations of network functions that run on virtualized infrastructure.
Why this is correct
Correct because VNFs replace physical appliances with software running on virtual machines or containers.
- ✗
Each VNF must be deployed on its own dedicated physical server to ensure performance isolation.
Why it's wrong here
Incorrect because NFV allows multiple VNFs to share the same physical hardware using virtualization techniques.
- ✗
The Virtualized Infrastructure Manager (VIM) is responsible for managing the lifecycle of VNFs.
Why it's wrong here
Incorrect because the VIM manages the NFVI resources; VNF lifecycle management is performed by the VNF Manager (VNFM).
- ✗
The NFV Orchestrator is primarily responsible for allocating virtual resources to VNFs.
Why it's wrong here
Incorrect because the NFV Orchestrator handles service lifecycle and resource orchestration across multiple VNFs, while resource allocation is done by the VIM.
