NEW QUESTION # 138
(When configuring access authentication, you need to define the items authorized to users in the authorization result. Which of the following items does not need to be defined?)
- A. Security group
- B. VLAN
- C. IP address
- D. ACL
Answer: C
Explanation:
In Huawei campus networks, access authentication and authorization are implemented based on the AAA framework. After a user is successfully authenticated, the network enforces anauthorization result, which defines what network resources the user is allowed to access and how traffic is controlled. These authorization results are typically delivered by the authentication server or configured locally on network devices.
According to HCIP Datacom Campus Network documentation,authorization results focus on policy and access control attributes, not basic network parameter assignment. Common authorization items includeVLAN assignment,security group assignment, andACL application. VLANs determine the user's logical network location, security groups enable group-based policy control, and ACLs restrict or permit traffic based on predefined rules. These elements directly affect access permissions and security enforcement.
AnIP address, however, does not need to be defined in the authorization result. In campus networks, IP addresses are usually assigned dynamically throughDHCP, either by a DHCP server or a DHCP relay function on network devices. The IP address allocation process is independent of user authorization and does not represent an access control policy.
Separating IP address assignment from authorization simplifies network design and improves scalability. It allows users to obtain IP addresses automatically while access rights are enforced consistently through identity-based policies. Therefore, among the given options,IP addressis not an item that must be defined in the authorization result.
Hence, the correct answer isB.

(The following figure shows the MAC address table of a Layer 2 VXLAN gateway. Which of the following statements are true?Choose all that apply.)
- A. The MAC address entry with the outbound interface 10.3.3.3 is learned from the remote VTEP through the VXLAN tunnel.
- B. Both 0000-0000-0010 and 5489-9893-48a3 belong to BD 10 and are in the same Layer 2 broadcast domain.
- C. The outbound interface corresponding to 5489-982d-77e2 is GE1/0/1.20. Because this interface belongs to BD 20, the host with 5489-982d-77e2 can directly communicate with the host with 5489-9893-48a3 at Layer 2.
- D. The outbound interface corresponding to 5489-9893-48a3 is GE1/0/1.10, which belongs to BD 10.
Answer: A,B,D
Explanation:
Comprehensive and Detailed 200 to 250 words of Explanation From HCIP Datacom Campus Network documents knowledge without any URL or Links:
In a Layer 2 VXLAN gateway, the MAC address table recordslocal and remote MAC addressesassociated with specific Bridge Domains (BDs) and outbound interfaces. Entries learned fromremote VTEPsare shown with an outbound interface that is aVXLAN tunnel endpoint IP address, such as10.3.3.3, indicating VXLAN-based learning.
StatementAis correct because both MAC addresses0000-0000-0010and5489-9893-48a3are associated with BD 10, meaning they are in the same Layer 2 broadcast domain.
StatementCis correct because MAC entries learned with an outbound interface displayed as an IP address representremote MAC addresses learned through the VXLAN tunnel.
StatementDis also correct. The MAC address5489-9893-48a3is learned from the local physical subinterface GE1/0/1.10, which belongs toBD 10, confirming local access.
StatementBis incorrect. Even though5489-982d-77e2is associated withGE1/0/1.20 (BD 20), hosts inBD 20 and BD 10 cannot communicate directly at Layer 2because they belong to different bridge domains.
Therefore, the correct answers areA, C, and D.
NEW QUESTION # 150
(Which of the following fields is not carried in a BGP EVPN Type 2 route?)
- A. L2VNI
- B. L3VNI
- C. IP Address
- D. IP Prefix
Answer: D
Explanation:
In a VXLAN BGP EVPN network, different EVPN route types are used to advertise specific kinds of control- plane information.BGP EVPN Type 2 routes, also known asMAC/IP Advertisement routes, are primarily used to advertise Layer 2 and host-level Layer 3 reachability information between VTEPs.
According to HCIP Datacom Campus Network documentation, a Type 2 route carriesMAC address information, and it can optionally carry ahost IP addressassociated with that MAC. This enables efficient MAC learning and ARP suppression within the VXLAN fabric. TheL2VNIis also included in Type 2 routes, as it identifies the Layer 2 broadcast domain to which the MAC and IP information belongs.
TheL3VNIis not used to identify a Layer 2 broadcast domain but is associated with Layer 3 VPN forwarding and inter-VNI routing. While L3VNI information is relevant in EVPN-based Layer 3 services, it is not the primary identifier in a Type 2 route. However, the key distinction in this question lies in the difference between host routes and prefix routes.
AnIP prefixrepresents a network segment rather than a single host and is advertised usingEVPN Type 5 (IP Prefix) routes, not Type 2 routes. Type 2 routes only carry host IP addresses, not IP prefixes. Therefore,IP Prefixis not carried in a BGP EVPN Type 2 route, making optionCthe correct answer.
NEW QUESTION # 151

- B. Apply a prefix-list to filter routes in the outbound direction of BGP neighbors.
- C. Configure BGP neighbor MD5 authentication
- D. Apply route-policy to the BGP neighbor inbound direction and set Local Preference.
Answer: D
NEW QUESTION # 152
In the deployment of the OSPF protocol in a wide area network, what is the core function of the ABR (Area Border Router)?
- A. Disable OSPF and use static routes to connect different areas.
- B. Connect different OSPF areas and pass inter-area routes (such as Type 3 LSA).
- C. Only external AS routes (Type 5 LSA) are transmitted; inter-area routes are not transmitted.
- D. Forward routes only within a single OSPF area, not across areas.
Answer: B
NEW QUESTION # 153
(Which of the following commands needs to be run in the BGP view to enable a VPN instance to advertise IP routes to the BGP-EVPN address family?)
- A. advertise irb
- B. advertise irbv6
- C. advertise l2vpn evpn
- D. advertise vpnv4
Answer: A
Explanation:
In a VXLAN BGP EVPN deployment, interconnection between Layer 2 and Layer 3 networks relies onIntegrated Routing and Bridging (IRB). According to HCIP Datacom Campus Network documentation, for a VPN instance to advertise its IP routes to the BGP EVPN control plane, the device must explicitly enable IRB route advertisement in the BGP view.
Theadvertise irbcommand is used to allow IP routes learned in a VPN instance to be advertised as EVPN Type 5 (IP Prefix) routes. These routes enable communication between different VNIs or between VXLAN segments and external Layer 3 networks. Without this command, the VPN instance routes remain local and are not distributed through the EVPN control plane, preventing proper Layer 3 connectivity across the VXLAN fabric.
The other options are incorrect in this context. Theadvertise vpnv4command is used in traditional MPLS VPN scenarios, not in BGP EVPN-based VXLAN networks. Theadvertise irbv6command is specific to IPv6 IRB scenarios and does not apply to IPv4 route advertisement unless explicitly required. Theadvertise l2vpn evpncommand is used to enable the EVPN address family itself but does not control the advertisement of IP routes from a VPN instance.
Therefore, to enable a VPN instance to advertise IP routes to the BGP EVPN address family in a VXLAN network, the correct command isadvertise irb.
NEW QUESTION # 154
In Huawei's SD-WAN solution, which of the following technologies can "real-time monitoring of the health status of the VPN tunnel between branch devices and headquarters, triggering alarms when abnormalities occur "?

- B. The tunnel condition is manually inspected periodically, and manual alarms are triggered when abnormalities are detected.
- C. Only monitor the physical status of the link, not the logical status of the tunnel.
- D. Disable tunnel monitoring function and rely on service interruption to detect anomalies.
Answer: A
NEW QUESTION # 155
