              Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 認定 H12-831_V1.0 試験問題 (Q11-Q16):

              質問 # 11
              Entries in a MAC address table are classified into dynamic, static, and blackhole entries. In addition, the MAC address table of a switch also contains service MAC address entries, which are typically converted from dynamic entries.

              正解：B

              解説：
              Huawei classifies the principal MAC address-table entries as dynamic, static and blackhole entries:
              * Dynamic entries are learned automatically from the source MAC addresses of received frames and are subject to aging.
              * Static entries are manually configured, do not age and remain after a saved configuration is restarted.
              * Blackhole entries are manually configured to discard frames sourced from or destined for specified MAC addresses.
              Service modules can further classify or convert dynamically learned entries according to a particular service.
              Huawei examples include secure MAC, authentication MAC, guest MAC and MUX MAC entries. These are collectively referred to as service MAC address entries. Their forwarding and aging behavior is controlled by the feature that created or converted them-for example, port security, access authentication or MUX VLAN.
              Therefore, the statement is correct: in addition to the three fundamental MAC-entry classes, a switch may contain service-specific MAC entries that are generally derived from or further classifications of dynamically learned entries. Huawei MAC address-entry classification

              After a fault occurs, you need to collect and back up various types of fault information in time as a reference for troubleshooting. In addition, when seeking emergency assistance from Huawei Technologies Co., Ltd.

              正解：A


              質問 # 13
              When the administrator configures the port security function of the switch, the static MAC address drift detection function is enabled at the same time. If the static AC address drift occurs later, the switch will protect the interface according to the configured action. Please match the name of the interface security protection action with the operation.

              正解：

              解説：


              質問 # 14
              In the OSPFv3 network shown in the figure, the OSPFv3 related parameters are the default configuration. When checking the LSDB on one of the devices, some content is omitted in the LSDB. The Router IDs of R1, R3, and R4 are 10.0.1.1, 10.0.3.3, and 10.0.4.4, respectively. The Origin Router part of some LSAs is hidden. Please complete this part.

              正解：

              解説：


              質問 # 15
              VLAN aggregation uses multiple sub-VLANs to isolate broadcast domains on a physical network and aggregates these sub-VLANs into a logical super-VLAN. Which of the following statements is true about VLAN aggregation?

              正解：D

              解説：
              A super-VLAN provides a shared Layer 3 gateway for its associated sub-VLANs, but the sub-VLANs remain separate broadcast domains. Because hosts in different sub-VLANs commonly use addresses from the same IP subnet, they initially attempt direct ARP resolution. The ARP broadcast cannot cross the sub-VLAN boundary. Enabling proxy ARP on the super-VLAN's VLANIF interface allows the switch to respond and then route traffic between the sub-VLANs. Therefore, option D is correct.
              The other options are incorrect:
              * A: The super-VLAN's VLANIF interface becomes Up only when at least one physical interface in an associated sub-VLAN is Up-not merely any physical interface on the switch.
              * B: Huawei explicitly prohibits configuring VLAN 1 as a super-VLAN.
              * C: Different sub-VLANs are independent broadcast domains and cannot communicate directly at Layer
              2. Their communication requires Layer 3 forwarding through the super-VLAN VLANIF interface, normally assisted by proxy ARP.
              Huawei also specifies that a super-VLAN contains no physical interfaces; physical interfaces belong to its sub- VLANs. Huawei Super-VLAN overview , Huawei super-VLAN restrictions
