Which of the following steps are mandatory to enable 802.1X authentication on GE0/0/2 and GE0/0/3 of SW3 and configure a RADIUS server to authenticate and deliver network access rights to users?
Answer: A,B,C,D
Explanation:
Understanding 802.1X Authentication in Enterprise Networks
# What is 802.1X?
802.1X is a network access control (NAC) protocol that enforces authentication before allowing a device to connect to a LAN.
It usesEAP (Extensible Authentication Protocol)overRADIUSfor user verification.
Typically deployed incorporate and campus networksforsecure wired and wireless access.
# How Does 802.1X Work?
1##Client (Supplicant) # Requests network access.
2##Switch (Authenticator) # Forwards request to RADIUS server.
3##RADIUS Server # Verifies credentials & grants access.
Mandatory Steps to Enable 802.1X on SW3
#A. Configure an AAA Scheme
Defines authentication, authorization, and accounting (AAA) methods.
Links802.1X authentication to the RADIUS server.
#B. Configure an Authentication Profile
Specifies how authentication is handled on the switch.
Associates802.1X authentication with an AAA scheme.
#C. Configure an Authentication Domain
Groups authentication policies for different user types.
MapsAAA scheme to user login requests.
#D. Configure an 802.1X Access Profile
Applies 802.1X authentication to specific switch ports (GE0/0/2 & GE0/0/3).
Ensures thatonly authenticated users can pass traffic.
Why Are All Four Steps Necessary?
#Each step plays a critical role in enabling 802.1X authentication and linking it to the RADIUS server.
#Without any one of these configurations, the 802.1X authentication process would fail.
Real-World Application:
Enterprise Wired Security:Ensures thatonly authenticated devicesaccess corporate networks.
University Campuses & Public Wi-Fi:Prevents unauthorized access tosecure LAN environments.

NEW QUESTION # 79
OSPF is a mature protocol and is unlikely to have route computation errors in a regular networking environment under correct configurations. Which of the following statements are correct about the possible causes preventing an OSPF neighbor relationship from entering Full state?
Answer: A,B,C,D
Explanation:
For OSPF neighbors to reach Full state, they must exchange LSAs (Link State Advertisements) properly and synchronize their databases.
Possible Causes Preventing OSPF from Entering Full State:
# A. A link works abnormally
* If the physical or Layer 2 link is unstable, OSPF Hello packets may be lost, preventing the Full state.
# B. The OSPF network types on both ends of the link are inconsistent
* OSPF network types (Broadcast, P2P, NBMA, etc.) must match on both ends.
* Example: If one router is P2P and the other is Broadcast, adjacency issues occur.
# C. The router IDs of neighbors are the same
* Router ID conflicts prevent OSPF adjacencies from forming.
* Each router must have a unique Router ID.
# D. The OSPF MTU values of interfaces on both ends of the link are different
* If MTU settings do not match, OSPF Database Description (DD) packets may be dropped, preventing Full state.

* HCIE-Datacom Study Material - OSPF Adjacency and Route Synchronization

The naming of SRv6 instructions complies with certain rules. You can quickly determine the function of an instruction based on the instruction name. Which of the following statements about the keywords in SRv6 instruction names are correct? (Select all that apply)
Answer: A,B,C
Explanation:
In Huawei'sSRv6 instruction namingsystem, each letter keyword represents a specific forwarding behavior:
X (Cross): Forwards packets viaspecified Layer 3 interfaces##
M (MAC): SearchesLayer 2 forwarding tableforbroadcast/multicast,not unicast## V (VPN): Searches theVPN routing table (VRF)for forwarding ## T (Table): Searches aspecific routing table (e.g., user-defined)## Correct answers: A, C, D
