NEW QUESTION # 158
Which of the following statements about configuring user access authentication is incorrect?

A. To implement network access control on users, you need to determine the domains to which they belong and the AAA schemes that they use.
B. You need to bind an access profile to an authentication profile to specify the user authentication mode. Then, apply the authentication profile to an interface to enable network access control.
C. You can configure an 802.1X access profile, a MAC access profile, a Portal access profile, or a multi-mode authentication profile based on the actual authentication requirements on the network.
D. If the RADIUS or HWTACACS server is used for authentication, you need to configure parameters for interconnection with the authentication server in the AAA scheme.
E. It incorrectly states you bind the access profile to the authentication profile, when in fact, the authentication profile binds the access profile and is applied to the interface.

Answer: B

Explanation:
Huawei's user access authentication configuration includes the following components:
AAA scheme: Defines how users are authenticated (local, RADIUS, HWTACACS, etc.).
Domain: Groups users and associates them with an AAA scheme.
Access profile: Defines access control rules like 802.1X, MAC, Portal, or multi-mode authentication.
Correct workflow:
Bind the authentication profile (which references the access profile) to the user access interface.
Not the other way around.
Incorrect statement:

YANG is a data modeling language for the definition of data sent over network management protocols such as NETCONF. Which of the following are basic YANG data models? (Select all that Apply)

A. Leaf node
B. Set node
C. Tree node
D. List node

Answer: A,D

Explanation:
The basic constructs in YANG data modeling include:
Leaf node - A single data element with a specific type (e.g., integer, string).
List node - A repeating set of elements, each structured the same.
Incorrect options:
A . Set node - ❌ Not a valid YANG construct.
D . Tree node - ❌ Not an individual data model element. The entire model forms a tree structure, but there is no "tree node" in YANG syntax.
Exact Extract - Huawei YANG Modeling Fundamentals:
"YANG defines elements such as leaf, list, container, choice, and leaf-list. 'Set' and 'tree' are not YANG node types." Reference:
