NEW QUESTION # 29
If a Portal authentication user goes offline but neither the access device nor the RADIUS server detects this event, many problems may occur. To prevent this from occurring, the access device needs to detect a user logout immediately, delete the user entry, and instruct the RADIUS server to stop accounting.
Which of the following can trigger a Portal user logout?(Select All that Apply)

  • A. The access device logs out the user.
  • B. The user initiates a logout request.
  • C. The Portal server logs out the user.
  • D. The authentication server logs out the user.

Answer: A,B,C,D

Explanation:
Comprehensive and Detailed Explanation:
* Portal authentication requires active session monitoring.
* User logout can be triggered by multiple methods:
* A. Portal server logout# The Portal system forcefully logs out a user.
* B. Authentication server logout# The authentication system revokes access.
* C. User-initiated logout# The user manually logs out via a Portal page.
* D. Access device logout# If the firewall detects inactivity, it can remove the session.
* Why are all options correct?
* Each method can trigger a user logout in Portal authentication.

NEW QUESTION # 30
In a Huawei network security environment, which of the following is a key advantage of using HWTACACS over RADIUS for device management authentication?
Options:

  • A. HWTACACS provides per-command authorization, allowing different privilege levels for different users.
  • B. HWTACACS does not support accounting, while RADIUS does.
  • C. HWTACACS operates over UDP, ensuring faster communication than RADIUS.
  • D. HWTACACS encrypts only passwords, while RADIUS encrypts the entire payload.

Answer: A

Explanation:
Understanding the Differences Between HWTACACS and RADIUS:
* HWTACACS(Huawei Terminal Access Controller Access-Control System) is aHuawei-enhanced version of TACACS+used forAAA (Authentication, Authorization, and Accounting).
* RADIUS (Remote Authentication Dial-In User Service)is also an AAA protocol but is mainly designed fornetwork access authentication, such asVPNs and wireless authentication.
Why is Option B Correct?
* HWTACACS supports per-command authorization, meaning administrators canassign different command privileges to different users.
* For example, ajunior network engineer may be allowed to view configurations but not modify them
, while asenior engineer has full access.
* RADIUS does not support granular command authorization, as it primarily controlsnetwork access rather than device management.


NEW QUESTION # 31
In the figure, if 802.1X authentication is used for wired users on the network, the network admission device and terminals must be connected through a Layer 2 network.

Options:

  • A. FALSE
  • B. TRUE

Answer: B

Explanation:
Understanding 802.1X Authentication in Wired Networks:
* 802.1X is a port-based network access control (PNAC) protocolthat requires aLayer 2 connection between thesupplicant (PC), the authenticator (switch), and the authentication server (e.g., RADIUS server).
* In wired networks,802.1X authentication occurs at the Ethernet switch (Layer 2 device), which enforces authenticationbefore allowing network access.
Why Must the Network Be Layer 2?
* 802.1X authentication operates at Layer 2 (Data Link Layer) before any IP-based communication (Layer 3) occurs.
* If the authentication device and user terminal were on different Layer 3 networks, the authentication packets (EAPOL - Extensible Authentication Protocol Over LAN)would not be forwarded.
* In the figure, the authentication control point is at theaggregation switch, which means thePC and switch must be in the same Layer 2 domain.
Components of 802.1X Authentication in the Figure:
* Supplicant (PC)# The device requesting network access.
* Authenticator (Aggregation Switch)# The switch controlling access to the network based on authentication results.
* Authentication Server (iMaster NCE-Campus & AD Server)# Verifies user credentials and grants or denies access.
* Layer 2 Connectivity Requirement# ThePC must be in the same Layer 2 networkas the Authenticatorto communicate via EAPOL.
Why "TRUE" is the Correct answer:
* 802.1X authentication is performed before IP addresses are assigned, meaning it can only operate in a Layer 2 network.
* EAPOL (Extensible Authentication Protocol Over LAN) messages are not routableand must stay within a single Layer 2 broadcast domain.
* In enterprise networks,VLAN-based 802.1X authentication is often used, where authenticated users are assigned to a specific VLAN.

* IEEE 802.1X Standard Documentation# Layer 2 Network Authentication


NEW QUESTION # 32
Network Access Control (NAC) is an end-to-end security control technology that works in combination with AAA to implement access authentication. Which of the following statements about NAC and AAA are true?(Select All that Apply)

  • A. An AAA server controls network access rights of users through authentication, authorization, and accounting.
  • B. AAA is mainly used for interaction between users and access devices.
  • C. NAC provides three authentication modes: 802.1X authentication, MAC address authentication, and Portal authentication.
  • D. NAC is mainly used for interaction between access devices and authentication servers.

Answer: A,B,C,D

Explanation:
Comprehensive and Detailed Explanation:
* Network Access Control (NAC) and AAA work together for secure network access.
* Key functions:
* A. AAA handles user-to-device authentication.
* B. NAC handles device-to-server authentication.
* C. NAC supports 802.1X, MAC authentication, and Portal authentication.
* D. AAA enforces authentication, authorization, and accounting.
* Why are all options correct?
* Each option correctly describes a function of NAC or AAA.
