Which three resource types are included in the NFV Infrastructure (NFVI)?

Hypervisor, operating system, and applications

Virtual machines, containers, and bare metal

A VNF is experiencing high latency in its network traffic. The VNF is running on a host with multiple other VNFs. The administrator suspects that the virtual switch is the bottleneck. Which NFVI configuration change would most likely reduce latency for this VNF?

Increase the number of virtual CPUs allocated to the VNF

Enable SR-IOV on the physical NIC and assign a virtual function to the VNF

Move the VNF to a different physical host

Increase the storage capacity for the VNF

Which statement accurately describes the relationship between VNFs and the NFV architectural framework?

VNFs are software implementations of network functions that run on the NFVI.

VNFs are part of the NFV Management and Orchestration layer.

VNFs are the physical servers that host virtual machines.

VNFs are physical appliances that are managed by the NFV Infrastructure.

What is the role of a VNF in delivering network services?

It manages the lifecycle of other VNFs

It provides the physical hardware for network connectivity

It performs a specific network function in software

It provides the virtualization layer for the NFVI

A network operator is deploying a VNF that requires high-throughput packet processing. To meet performance requirements, they plan to use SR-IOV to allow the VNF to access physical NICs directly. Which component of the NFVI must support this capability?

The compute resource (hypervisor and server)

The network resource (virtual switch)

NFV Architecture JN0-214 Practice Questions (Page 5)

Part of the Cloud Infrastructure (NFV and SDN) domain, which makes up ~19% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–11 in this domain), expect 1–2 from this objective — we provide 28 practice questions to prepare you well beyond it.
