BOrchestration above Network Function Management above Infrastructure Management

CNetwork Function Management above Orchestration above Infrastructure Management '

DInfrastructure Management above Network Function Management above Orchestration

Suggested Answer: B

The ETSI MANO Model operational stack is defined as Orchestration above Network Function Management above Infrastructure Management.The ETSI MANO Model is a framework that defines the architecture and interfaces for the management and orchestration of network functions virtualization (NFV) in cloud networks1.The ETSI MANO Model consists of three main components: Infrastructure Management, Network Function Management, and Orchestration2.Infrastructure Management is responsible for managing the physical and virtual resources that host the network functions, such as servers, storage, switches, hypervisors, and virtual machines2.Network Function Management is responsible for managing the configuration, monitoring, and optimization of the network functions, such as scaling, healing, and updating2.Orchestration is responsible for coordinating the allocation and release of resources for network services and network slices, such as instantiation, termination, and modification2.The ETSI MANO Model operational stack is defined as Orchestration above Network Function Management above Infrastructure Management, meaning that Orchestration is the highest level of abstraction and control, Network Function Management is the intermediate level, and Infrastructure Management is the lowest level2.Reference:1: Nokia Bell Labs Distributed Cloud Networks, Unit 5: New Services Automation, Section 5.3: Orchestration2: Module by Module - Self Study Note Guide - training2

I remember it differently, maybe I need to review!

Lorriane 11 months ago

100% agree with A, makes the most sense!

Chandra 11 months ago

Wait, is it really that way? Sounds off to me.

Elke 11 months ago

I thought it was Orchestration on top, but I guess not!

Nidia 12 months ago

It's definitely Infrastructure Management above Orchestration above Network Function Management.

Ilona 12 months ago

I thought it was Infrastructure Management at the bottom, but now I'm confused about whether it goes above or below Orchestration.

I feel like Network Function Management should be above Orchestration, but I might be mixing it up with another model we studied.

Robt 1 year ago

I remember practicing a question similar to this, and I think Infrastructure Management should be at the top, but I can't recall the exact sequence.

Larae 1 year ago

I think the correct order is Orchestration above Network Function Management above Infrastructure Management, but I'm not entirely sure.

Domitila 1 year ago

I'm a little confused by the wording of this question. Let me think it through carefully before selecting an answer.

Chu 1 year ago

Option A sounds right to me - infrastructure management is the foundation, with orchestration and network function management on top. I'm confident that's the right answer.

Juan 1 year ago

I think I've got a good handle on the ETSI MANO model, so I'll go with option B. Orchestration is the key component, sitting above the other two layers.

Jin 1 year ago

Hmm, I'm a bit unsure about this one. I'll need to review my notes on the MANO model again to make sure I understand the correct order of the layers.

Lillian 1 year ago

I'm a bit confused by the different options. I'll need to review the Magento documentation on managing multilingual product attributes to make sure I fully grasp the best practice here.

Sharita 1 year ago

This question seems tricky. I want to say central authentication and central switching, but I'm confused about the difference with local options.

Kathrine 1 year ago

Hmm, local rules usually take precedence, so maybe it's option A? But I'm not totally sure.

Justine 2 years ago

That makes sense, since orchestration usually manages the overall coordination of tasks.

Deonna 2 years ago

Interesting, seems like there are different opinions on this. I think I'll go with option B) Orchestration above Network Function Management above Infrastructure Management.

Kirk 2 years ago

I remember studying that it's Infrastructure Management above Network Function Management above Orchestration.

Jackie 2 years ago

I think it might be Network Function Management above Orchestration above Infrastructure Management.

Azalee 2 years ago

I believe it's Orchestration above Network Function Management above Infrastructure Management.
