Discuss Nokia BL0-220 Exam Topic 6 Question 28

Which of the following statements are correct regarding the characteristics of microservices? (Select 2)

AMicroservices are chained in order to build an application.

BAll functions are the same in microservices.

CMonolithic applications breaks functions in small pieces called microservices.

DMicroservices are limited to 10 per application.

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

Limited to 10 per app? That sounds way off!

Rene 11 months ago

Monolithic apps can be broken down into microservices, true!

Genevive 11 months ago

Wait, are we really saying all functions are the same? That’s not right.

Youlanda 11 months ago

Totally agree, they should be loosely coupled!

Joana 12 months ago

Microservices are independent, not chained.

Xochitl 12 months ago

I feel like D is definitely wrong; I don’t recall any limit on the number of microservices in an application.

Rosalia 1 year ago

I practiced a question similar to this, and I think C is about how microservices are created from monolithic apps, so that one might be right.

Dick 1 year ago

I’m not sure, but I think microservices actually allow for different functions, so B seems incorrect too.

Royal 1 year ago

I remember that microservices are supposed to be independent, so I think A might be wrong about chaining them.

Verda 1 year ago

Microservices, huh? I'm not as familiar with this topic as I'd like to be. I'll have to read through the options carefully and try to reason it out.

Isabella 1 year ago

Ah, this is a great question! I've studied microservices quite a bit, so I feel confident I can identify the correct statements.

Nathan 1 year ago

Okay, let's see here. I remember learning about microservices, but I'm a bit fuzzy on the details. I'll have to think this through carefully.

Earnestine 1 year ago

Hmm, this is a tricky one. I'm not entirely sure about the characteristics of microservices, but I'll give it my best shot.

Reena 1 year ago

I think I've got a good handle on microservices, so I'll try to tackle this one.

Johanna 1 year ago

Haha, 10 microservices per app? That's like saying a car can only have 10 parts. Microservices are all about flexibility and scalability.

Hannah 1 year ago

D is just ridiculous. There's no hard limit on the number of microservices in an application. The more the merrier, as long as they're well-designed!

I agree, D is definitely not correct. There's no limit on the number of microservices in an application.

C) Monolithic applications breaks functions in small pieces called microservices.

↳ replying to Hannah

A) Microservices are chained in order to build an application.

Elke 1 year ago

B is definitely wrong. The whole point of microservices is to have different, specialized functions instead of a one-size-fits-all approach.

Glenn 1 year ago

↳ replying to Elke

I agree, B is definitely wrong. Microservices are all about having specialized functions.

C) Monolithic applications breaks functions in small pieces called microservices.

A) Microservices are chained in order to build an application.

Linette 2 years ago

But microservices are not limited to 10 per application, so D is incorrect.

Georgene 2 years ago

I think A and C are the correct answers. Microservices are designed to be loosely coupled and independent, not chained together like a monolith.

Maurine 1 year ago

↳ replying to Georgene

So, A and C are the correct statements regarding the characteristics of microservices.

Jovita 1 year ago

↳ replying to Georgene

I believe D is not true. There is no set limit to the number of microservices in an application.

Dortha 1 year ago

↳ replying to Georgene

I think B is incorrect. Microservices can have different functions.

Quentin 1 year ago

↳ replying to Georgene

I agree, A and C are the correct answers. Microservices are meant to be independent.

Elinore 2 years ago

I disagree, I believe B and D are the correct statements.

Linette 2 years ago

I think A and C are correct.
