350-401 Practice Question: Which three statements about NFV use cases and…
Which three statements about NFV use cases and deployment models are true? (Choose three.)
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
✓
Virtual CPE (vCPE) is a common NFV use case that replaces physical routers and firewalls at customer sites with software-based functions.
NFV is used to virtualize various network functions. Virtual CPE (vCPE) replaces physical customer premises equipment with software running on standard hardware. Virtual Evolved Packet Core (vEPC) is a key use case in mobile networks. NFV can be deployed on-premises or in the cloud. Option A is correct because vCPE is a common NFV use case. Option B is correct because vEPC virtualizes mobile core functions. Option C is correct because NFV supports both on-prem and cloud deployment. Option D is incorrect because NFV does not require dedicated hardware; it uses standard servers. Option E is incorrect because NFV can scale dynamically, not just statically.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Virtual CPE (vCPE) is a common NFV use case that replaces physical routers and firewalls at customer sites with software-based functions.
Why this is correct
Correct because vCPE is a well-known NFV application where network functions like routing and firewall run as VNFs on standard hardware at the customer premises or in the cloud.
- ✓
Virtual Evolved Packet Core (vEPC) virtualizes mobile core network functions such as MME, SGW, and PGW.
Why this is correct
Correct because vEPC is a key NFV use case in 4G/5G networks, running mobile core functions as software on standard servers.
- ✓
NFV can be deployed on-premises, in a private cloud, or in a public cloud infrastructure.
Why this is correct
Correct because NFV is cloud-agnostic and can be deployed in various environments, including on-premises data centers, private clouds, and public cloud platforms.
- ✗
NFV requires dedicated hardware appliances for each virtualized network function.
Why it's wrong here
Incorrect because NFV specifically aims to eliminate dedicated hardware by running network functions as software on general-purpose servers.
- ✗
NFV deployments are limited to static, non-scalable configurations.
Why it's wrong here
Incorrect because NFV enables elastic scaling; VNFs can be instantiated, scaled out, and terminated dynamically based on demand.
