Exam 350-501 topic 1 question 193 discussion

Correct Answer: B: FIREWALL VNF stands for virtualized network function, and commonly refers to the software form of network appliances such as a router, firewall, load-balancer etc. VNFs are mostly deployed as virtual machines (VMs) on Linux KVM or VMware vSphere hypervisors

Network is not a service, but firewall is.

A VNF, or Virtual Network Function, is a software-based network function that is deployed on a virtual machine (VM). VNFs are used to virtualize network functions that were traditionally implemented on dedicated hardware appliances. VNFs are used in a variety of networking applications, including: * Routing: VNFs can be used to implement routing functions, such as BGP and OSPF. * Firewalling: VNFs can be used to implement firewalling functions, such as packet filtering and intrusion detection. * Load balancing: VNFs can be used to implement load balancing functions, such as distributing traffic across multiple servers. * VPNs: VNFs can be used to implement VPNs, which provide secure connections between networks.

Based on the provided options, if we are to pick one option as a VNF role, the most appropriate choice would be: B. Firewall A firewall is a common example of a VNF role. It is responsible for network security, controlling and monitoring network traffic based on predetermined security policies and rules. A firewall VNF provides essential functions like access control, packet filtering, and threat prevention to secure the network against unauthorized access and malicious activities. While other options like network, storage, and compute are fundamental components of a network infrastructure, a firewall specifically represents a VNF role that focuses on security-related functionalities.

I am changing to B - Fihttps://www.examtopics.com/exams/cisco/350-501/view/#rewall. Wording is confusing! I think it is asking which of the options can be a VNF ie a physical device which can be virtualized by a VNF so FIREWALL is the only sensible option they provide. Others would be a Router, WAN Accelerator, WLAN controller. Storage, Network and Compute actual appliances that you can virtualize.

Please change the answer to B: Firewall. Sure, it's a network service, but firewall is a VNF role!

Surely not Firewall but Network "A virtual network function (VNF) is the virtual version of a hardware device's network function. VNFs are available as virtual machines or containers"

Firewall is a VNF, network is vague and doesn't describe a function

I’d say a VNF is a network service, so I go with A , if the question asked for examples of a VNF, then would of chosen B. But didn’t so A for me.

I'd be leaning toward A also, as it's in the name Network Functions Virtualization (NFV)

I think is NETWORK - 'A', coz is more general Virtual Network Function (VNF) is one or more virtual machines performing a single network function.

VNF: One or more virtual machines performing a single network function.
