Huawei HCIA-Datacom V2.0 H12-811_V2.0 Prüfungsfragen mit Lösungen (Q69-Q74):

69. Frage
Assume that you cannot configure an IP address for GE1/0/1 on a Huawei switch. Which of the following commands can you run in the interface view to resolve this problem?

Antwort: A

Begründung:
On Huawei switches, a physical Ethernet interface usually works as a Layer 2 switch port by default. A Layer
2 interface cannot be assigned an IP address directly. If an administrator wants to configure an IP address on such an interface, the interface must first be converted into a Layer 3 interface. The command used for this is undo portswitch, so option B is correct.
After this command is executed, the interface no longer behaves as a Layer 2 switching port and can then support Layer 3 features such as direct IP address configuration. Options A, C, and D are all Layer 2 port-type commands used to configure the interface as a trunk, access, or hybrid port. These commands do not solve the problem because they keep the interface operating at Layer 2. HCIA-Datacom emphasizes the difference between Layer 2 switching interfaces and Layer 3 routed interfaces on switches. Understanding when to use undo portswitch is important in campus network deployment, especially when configuring routed uplinks, management interfaces, or inter-device Layer 3 links on switches.


70. Frage
Which of the following IPv6 addresses is a link-local address ?

Antwort: C

Begründung:
In IPv6, link-local addresses use the prefix FE80::/10 . These addresses are automatically generated or configured for communication on the local link only and are not routed across Layer 3 boundaries. Therefore, among the given options, FE80::FA63:DBFF:FE9E:10 is the correct link-local address, making option C correct.
Options A and B belong to the Unique Local Address (ULA) space, which uses the prefix FC00::/7 . These addresses are intended for private internal IPv6 networks, somewhat similar in purpose to private IPv4 address ranges, but they are not link-local addresses. Option D , which starts with 2001::, is a global unicast address , used for routable communication across IPv6 networks. HCIA-Datacom teaches that link-local addresses are essential in IPv6 because they are used for functions such as neighbor discovery, router discovery, and routing protocol communication on the local segment. Even when a device has global unicast addresses, the link-local address still plays an important role in normal IPv6 operation and protocol adjacency establishment.


71. Frage
AAA is short for authentication, authorization, and accounting. The accounting function records only the fees incurred when users use network resources, but not the Internet access traffic or duration.

Antwort: B

Begründung:
The accounting function in AAA records user activity details such as login/logout times, session duration, accessed services, and traffic statistics. It is not limited to recording fees; it also tracks usage data for auditing, monitoring, and billing purposes.


72. Frage
On a switched network where STP is enabled on all devices, when a downstream device detects a topology change, it continuously sends configuration BPDUs to the upstream device until the root bridge is informed of the topology change.

Antwort: B

Begründung:
In STP, topology change information is propagated via TCN (Topology Change Notification) BPDUs, not by continuously sending configuration BPDUs. When a change is detected, the switch sends TCN BPDUs toward the root bridge through the upstream path, and the root bridge then informs the network using configuration BPDUs with updated flags. The behavior described is therefore incorrect.


73. Frage
After checking the status of GE0/0/1 on R1, you obtain the command output shown below. Which of the following statements are true? (Choose all that apply.)

Antwort: A,B,D

Begründung:
The interface status shows both the physical layer and line protocol are UP, confirming the physical status is UP. The output explicitly indicates PVID: 1, so the VLAN ID is 1. The hardware address field displays b0c7-8733-d65c, which is the MAC address of the interface. The port mode is COMMON COPPER, meaning it is a copper Ethernet interface rather than an optical interface, so the statement about optical type is incorrect.
