A network administrator is evaluating whether to deploy a virtual firewall or a physical firewall for a high-traffic data center. The administrator is concerned about the performance overhead of virtualization. Which technique can help mitigate this overhead for the VNF?

Increasing the number of virtual CPUs allocated to the VM.

Using SR-IOV to allow the VM to directly access the physical NIC.

Using a management network for data traffic.

Deploying the VNF on a host with more RAM.

A cloud provider offers a service where customer traffic passes through a sequence of VNFs: first a firewall, then a load balancer, and finally a WAN optimizer. The VNFs are deployed as virtual machines on the provider's infrastructure. What is this deployment model called?

Network function virtualization infrastructure (NFVI)

Software-defined networking (SDN) controller

Virtual network function component (VNFC)

In an NFV framework, what is the primary responsibility of the VNF Manager (VNFM)?

To manage the lifecycle of VNF instances, such as instantiation, scaling, and termination

To manage the physical infrastructure, including servers and storage

To orchestrate the overall network services and VNFs across the NFV framework

To provide the virtualized compute, storage, and network resources

Virtual Network Functions (VNFs) JN0-214 Practice Questions (Page 1)

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 27 practice questions to prepare you well beyond it.
