A company is deciding between a VNF and a physical network function for a new branch office. The branch office has limited space and power. Which benefit of a VNF is most relevant to this constraint?

VNFs always have lower latency than physical devices.

VNFs provide higher throughput than physical devices.

VNFs are easier to secure than physical devices.

VNFs can be consolidated on existing servers, reducing the need for additional hardware.

Which component in the NFV framework is responsible for coordinating the lifecycle of network services and VNFs across the entire infrastructure?

Element Management System (EMS)

A cloud service provider is deploying VNFs for a new customer. The customer requires that all VNFs be placed in the same data center to minimize latency between them. Which deployment model best meets this requirement?

Place the VNFs in different availability zones to ensure high availability.

Place the VNFs in different regions to improve disaster recovery.

Place the VNFs on the same physical server to maximize performance.

Place all VNFs in the same availability zone within the data center.

A network engineer is deploying a VNF that performs deep packet inspection (DPI). The engineer notices that the VNF's throughput is lower than expected. Which factor is most likely to cause this performance degradation?

The VNF is running on a host with insufficient CPU resources allocated to the VM.

The VNF is using a management network for data traffic.

The VNF is using a virtual switch that does not support jumbo frames.

The VNF is deployed in a different availability zone than the client.

What is a common trade-off when replacing a physical network function with a VNF?

VNFs may introduce additional performance overhead due to virtualization

VNFs cannot be managed by orchestration tools

VNFs are always more expensive to license

VNFs require physical appliances to function

Virtual Network Functions (VNFs) 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 27 practice questions to prepare you well beyond it.
