[All JN0-214 Questions]

The openstack user list command uses which OpenStack service?

Show Suggested Answer Hide Answer
Suggested Answer: B

OpenStack provides various services to manage cloud infrastructure resources, including user management. Let's analyze each option:

A . Cinder

Incorrect: Cinder is the OpenStack block storage service that provides persistent storage volumes for virtual machines. It is unrelated to managing users.

B . Keystone

Correct: Keystone is the OpenStack identity service responsible for authentication, authorization, and user management. The openstack user list command interacts with Keystone to retrieve a list of users in the OpenStack environment.

C . Nova

Incorrect: Nova is the OpenStack compute service that manages virtual machine instances. It does not handle user management.

D . Neutron

Incorrect: Neutron is the OpenStack networking service that manages virtual networks, routers, and IP addresses. It is unrelated to user management.

Why Keystone?

Identity Management: Keystone serves as the central identity provider for OpenStack, managing users, roles, and projects.

API Integration: Commands like openstack user list rely on Keystone's APIs to query and display user information.

JNCIA Cloud Reference:

The JNCIA-Cloud certification covers OpenStack services, including Keystone, as part of its cloud infrastructure curriculum. Understanding Keystone's role in user management is essential for operating OpenStack environments.

For example, Juniper Contrail integrates with OpenStack Keystone to enforce authentication and authorization for network resources.

The correct answer is B) Keystone. It's the identity service, duh. Unless this is one of those 'trick questions' where the right answer is actually 'all of the above'.

Wait, we have an 'OpenStack user list' command? I thought we just used 'openstack user list' like normal people. This exam is already testing my sanity.

Oh, this is easy! It's Cinder, the storage service. Where else would you list all the users, if not in the storage system?

Hmm, this one's tricky. I'm gonna go with Neutron, because that's the networking service, and users are all about that network access, am I right?

Actually, the correct answer is Keystone, which manages authentication and authorization for OpenStack services.

I think you're on the right track with Neutron, it does handle networking services.

Hold up, is this a trick question? I thought the user list command was a Nova thing, you know, for managing instances and all that.

I'm not sure, but I think it might be C) Nova because it manages compute resources.
