                                                      Which of the following statements about configuring user access authentication is incorrect?

                                                      Answer: C

                                                      Explanation:
                                                      Huawei'suser access authentication configurationincludes 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 theauthentication profile(which references the access profile) to theuser access interface.
                                                      Not the other way around.
                                                      Incorrect statement:
                                                      D).It incorrectly states youbind the access profile to the authentication profile, when in fact, theauthentication profile binds the access profileand is applied to the interface.
                                                      Correct answer: D

                                                      The SRv6 Locator is 2001:DB8:ABCD::/64 → This defines the segment routing namespace for this node. ✅ Dynamic Segment (SID) = 32 bits → Defined dynamically per segment. ✅ Args Field = 32 bits → Used for function arguments. ✅
                                                      ❌ (B) Incorrect → Static segments are NOT explicitly defined as 32-bit fields in Huawei SRv6.

                                                      NEW QUESTION # 82
                                                      Which of the following community attributes ensure that BGP routes are transmitted only within an AS?

                                                      Answer: C

                                                      Explanation:
                                                      In BGP, community attributes help control the advertisement scope of BGP routes. Here's what each option means:
                                                      No_Export: This well-known community attribute prevents BGP routes from being advertised to external BGP (EBGP) peers. Routes with this attribute can still be advertised to internal BGP (IBGP) peers within the same AS. This ensures that the route remains within the originating AS.
                                                      No_Advertise: This attribute means that the route should not be advertised toanyBGP peer, whether internal or external.
                                                      Internet: Indicates that the route can be advertised to all BGP peers, both internal and external, with no restrictions.
                                                      No_Export_Subconfed: Similar to No_Export, but it also restricts advertisement to peers within a BGP confederation. It ' s more specific and not generally used just to keep routes inside one AS.
                                                      Therefore, the correct answer isB. No_Export, as it is the attribute that ensures BGP routes remain within the AS by not being sent to EBGP peers.
