Huawei HCIA-Datacom V2.0 H12-811_V2.0 Prüfungsfragen mit Lösungen (Q91-Q96):

91. Frage
On the OSPF network shown in the figure, all IP addresses can communicate with each other.
Then the following configurations are added on R1:

Which IP address of S1 can successfully ping 10.2.23.3?

Antwort: C

Begründung:
According to the topology and the original question scenario, the correct answer is 10.2.1.1, so option B is selected. In HCIA-Datacom troubleshooting questions of this type, the goal is usually to identify the correct management address, next-hop interface address, or testing destination based on the addressing design shown in the figure.
The answer depends on the role of the device and the direction of the connectivity verification. In such topologies, each interface belongs to a specific network segment, and the selected address must match the intended test target on that segment. If the test is being performed toward the neighboring device or a specific reachable interface, using the correct IP on the proper subnet is essential. An incorrect address may still look familiar from the topology but would not represent the right test endpoint. HCIA-Datacom places strong emphasis on reading topology labels carefully, matching interface addresses to subnet assignments, and choosing the correct destination when using tools such as ping, tracert, or service-specific connectivity tests. This question mainly checks address recognition accuracy in a troubleshooting context.


92. Frage
On the network shown in the figure, the administrator creates Eth-Trunk 1 in manual mode on SW1 and SW2, and adds GE1/0/1 and GE1/0/2 on both switches to the Eth-Trunk. After the administrator runs the display interface brief command on SW1, the administrator finds that GE1/0/1 is Up and GE1/0/2 is Down. Which of the following statements is true about this scenario?

Antwort: A

Begründung:
For an Eth-Trunk operating in manual load-balancing mode, the logical Eth-Trunk interface can remain Up as long as at least one member link is operational and properly added to the trunk.
Therefore, if GE1/0/1 is Up and GE1/0/2 is Down, Eth-Trunk 1 can still stay Up, making option A correct.


93. Frage
On the network shown in the figure, GE1/0/1, GE1/0/2, and GE1/0/3 of SW1 are directly connected to SW2, and GE1/0/4 of SW1 is directly connected to SW3. The administrator runs the interface eth-trunk 1 command on SW1 and SW2 to create an Eth-Trunk to increase link bandwidth. Which of the following statements are true about this scenario?

Antwort: A,B,C

Begründung:
LACP mode and manual load-balancing mode behave differently when an Eth-Trunk contains a link connected to the wrong peer. In LACP mode, member interfaces exchange LACPDUs and the switches determine which physical links can participate in the same aggregation. GE1/0/1 through GE1/0/3 are correctly connected between SW1 and SW2, so they can form an operational LACP Eth-Trunk. GE1/0/4 is connected to SW3 and cannot successfully negotiate as a member of the SW1-SW2 LAG; it is therefore not used for service forwarding to SW3. This makes A and B true. In manual mode, there is no LACP negotiation to validate that every member terminates on the same peer. If GE1/0/4 is manually placed in the trunk, the device may treat it as a forwarding member and hash some traffic onto that link toward SW3. The trunk does not automatically go Down solely because of that incorrect peer connection. Therefore C is false and D is true.


94. Frage
On the network shown in the figure, the three PCs belong to VLAN 2. When configuring interface-based VLAN assignment, the administrator only forgets to configure the PVID of GE1/0/1. However, PC1 can still communicate with PC2 at Layer 2.

Antwort: B

Begründung:
Interface-based VLAN assignment determines the VLAN associated with an Ethernet frame according to the configuration of the receiving interface.
When an access interface receives an untagged frame, the switch assigns the frame to the VLAN specified by its Port VLAN ID (PVID).
In this scenario, the administrator forgets to configure the PVID of GE1/0/1 on SW1. Consequently, the interface retains its default PVID of VLAN 1.
PC1 sends untagged Ethernet frames through GE1/0/1, so those frames enter VLAN 1. Meanwhile, PC2 belongs to VLAN 2.
Because VLAN 1 and VLAN 2 represent separate Layer 2 broadcast domains, the switch does not directly forward traffic between them.
Without additional inter-VLAN routing or changes to VLAN membership, PC1 cannot communicate with PC2.
Therefore, the statement is FALSE.


95. Frage
Each host has its own network interface card (NIC). Each NIC is assigned a globally unique MAC address during manufacturing. Which of the following is a valid MAC address for a host's NIC?

Antwort: D

Begründung:
A valid unicast MAC address must be globally unique and must not be a multicast or broadcast address. The least significant bit of the first octet determines unicast or multicast; in this case, the address starting with 02 indicates a locally administered address (still valid for a NIC). Other options include multicast (01, FF) or broadcast (FF-FF-FF-FF-FF-FF), which are not valid individual host MAC addresses.
