Huawei HCIA-Datacom V2.0 認定 H12-811_V2.0 試験問題 (Q42-Q47):

質問 # 42
The figure shows the simplified topology of an enterprise campus network. On this network, the aging time of dynamic MAC address entries on switches is 300 seconds.
The administrator connects PC1 to GE1/0/1 of SW1 and successfully pings the IP address of PC2 from PC1.
Then, the administrator disconnects the Ethernet cable of PC1
from GE1/0/1 of SW1, immediately connects the cable to GE1/0/2 of SW1, and pings the IP address of PC2 from PC1. Which of the following operations does SW1 perform after receiving a data frame from PC1 when PC1 is connected to GE1/0/2 of SW1?

A. SW1 saves the mapping between the MAC address of PC1 and GE1/0/1, and also keeps the mapping between the MAC address of PC1 and GE1/0/2.
B. SW1 deletes all MAC address entries and relearns them from all ports.
C. SW1 does not update the MAC address table until the original entry ages out.
D. SW1 saves the mapping between the MAC address of PC1 and GE1/0/2 and deletes the mapping between the MAC address of PC1 and GE1/0/1.

正解：D

解説：
An Ethernet switch learns MAC address entries dynamically by examining the source MAC address of incoming frames. When SW1 first receives frames from PC1 on GE1/0/1, it creates a MAC address table entry mapping PC1's MAC address to that port. If PC1 later sends frames that arrive on GE1/0/2, SW1 updates the learned entry to reflect the new incoming interface. Therefore, option B is correct: SW1 saves the mapping between PC1's MAC address and GE1/0/2 and removes or overwrites the old mapping associated with GE1/0/1.
Option A is incorrect because a single dynamic MAC address is not normally maintained on two different ports within the same VLAN at the same time; that would cause forwarding ambiguity. Option C is incorrect because a normal move of one MAC address does not require clearing the entire MAC table. Option D is also incorrect because switches update MAC learning dynamically upon receiving new source traffic and do not have to wait for the previous entry to age out. HCIA-Datacom uses this principle to explain MAC address learning, migration, and troubleshooting of loops or host movement in switched Ethernet networks.

質問 # 43
During VLAN planning for a campus network, VLAN IDs for different service types must be allocated consecutively, without redundancy, to prevent omissions in future allocations.

A. TRUE
B. FALSE

正解：B

解説：
This statement is false . In campus network VLAN planning, VLAN IDs do not have to be allocated strictly consecutively without any gaps. In fact, leaving some reserved VLAN IDs is often a practical and recommended design approach. VLAN planning should focus on clarity, scalability, maintainability, and service separation , rather than on forcing all VLAN IDs to be contiguous.
For example, an administrator may reserve certain VLAN ranges for user access, voice services, management, wireless services, guest access, future expansion, or specific departments. Such structured planning makes later network expansion easier and reduces the risk of service conflicts or disruptive renumbering. HCIA- Datacom emphasizes that good campus network planning should consider current requirements and future growth. Consecutive allocation may look tidy at first, but it can actually reduce flexibility and make later additions more difficult. Therefore, the idea that VLAN IDs must be assigned consecutively without redundancy to avoid omissions is not a correct design principle. Reasonable reservation and categorized allocation are often more beneficial in real enterprise campus networks.

質問 # 44
A router ID uniquely identifies a device in an AS, and must be present before the device can run OSPF. For a device running OSPFv2, if no router ID is manually configured, the system automatically selects one.

A. FALSE
B. TRUE

正解：B

解説：
In OSPFv2, a router ID is required for OSPF to operate and uniquely identifies each router within an AS. If no manual router ID is configured, the system automatically selects the highest IP address of a loopback interface; if no loopback exists, it selects the highest IP address of a physical interface. Therefore, the statement is correct.

質問 # 45
In the figure, both PC1 and PC2 belong to VLAN 10. Interface GE1/0/1 on SW1 is a trunk interface with the default PVID, and interface GE1/0/2 on SW1 is an access interface in VLAN 10. Which of the following statements are true about the forwarding of data frames between PC1 and PC2? (Select all that apply)

A. The data frame processed inside SW1 does not carry any VLAN tag.
B. SW1 accepts the data frame sent from PC1 to PC2, but discards the data frame returned from PC2 to PC1.
C. After receiving the data frame sent from PC1 to PC2, SW1 adds the VLAN 10 tag to the data frame and then accepts the data frame.
D. SW1 removes the VLAN 10 tag from the data frame before forwarding it from GE1/0/2 to PC2.

正解：C、D

解説：
When a switch receives an untagged frame from a user host on an access interface , it associates that frame with the VLAN configured on the interface. In this scenario, PC1 and PC2 are in VLAN 10, and GE1/0/2 is an access interface in VLAN 10. After SW1 receives the frame from PC1, it internally associates the frame with VLAN 10 , so option A is correct in the practical VLAN-processing sense used in HCIA-Datacom questions.
When the frame is forwarded out an access interface toward PC2, the switch sends it without a VLAN tag , because end hosts normally do not process 802.1Q tags. Therefore, option D is correct. Option B is incorrect because both hosts are in the same VLAN and can communicate normally; SW1 does not discard the return traffic for that reason. Option C is not correct in the standard VLAN switching model used by Huawei training, because the switch performs forwarding based on VLAN membership and internally processes the frame as belonging to VLAN 10. This question mainly checks understanding of access/trunk behavior and tag handling on ingress and egress.

質問 # 46
R1 has the following configurations:
[R1] radius-server template 1
[R1-radius-1] radius-server authentication 10.1.6.6 1812
[R1-radius-1] radius-server accounting 10.1.6.6 1813
[R1-radius-1] radius-server shared-key cipher YsHsjx_202206139
[R1-radius-1] quit
[R1] aaa
[R1-aaa] authentication-scheme auth1
[R1-aaa-authen-auth1] authentication-mode radius
[R1-aaa-authen-auth1] quit
[R1-aaa] accounting-scheme acc1
[R1-aaa-accounting-acc1] accounting-mode radius
[R1-aaa-accounting-acc1] quit
[R1-aaa] domain huawei.com
[R1-aaa-domain-huawei.com] authentication-scheme auth1
[R1-aaa-domain-huawei.com] accounting-scheme acc1
[R1-aaa-domain-huawei.com] radius-server 1
[R1-aaa-domain-huawei.com] quit
[R1-aaa] quit
Which of the following statements is true?

A. The user cannot obtain authorization information after being authenticated because the IP address of the authorization server is not configured in the RADIUS server template.
B. RADIUS does not support accounting. Even if an accounting server is specified in the RADIUS server template, accounting cannot be performed when terminals access the network.
C. When a terminal uses the user name hcia-datacom@huawei.com to initiate authentication, RADIUS authentication is used.
D. When a terminal initiates an authentication request, R1 needs to first establish a TCP connection with the server whose IP address is 10.1.6.6.

正解：C

解説：
Option D is correct. The AAA configuration binds the domain huawei.com to the authentication scheme auth1, which uses RADIUS as the authentication mode, and to the accounting scheme acc1, which also uses RADIUS. Therefore, when a user logs in with a user name in the format hcia-datacom@huawei.com, the device parses the suffix @huawei.com, matches the domain, and applies the configured RADIUS authentication method.
