問題 #50
On the network shown in the figure, GE1/0/1 and GE1/0/2 of SW1 are access interfaces, and their PVIDs are VLAN 2 and VLAN 3 respectively. GE1/0/1 of SW2 is also an access interface, and its PVID is VLAN 4.
Which of the following configurations on SW1 and SW2 can ensure that data packets sent from PC1 and PC2 can reach PC3?

  • A. Configure GE1/0/3 of SW1 as a hybrid interface, add it to VLAN 2 and VLAN 3 in untagged mode, and set its PVID to VLAN 4.
  • B. Configure GE1/0/3 of SW2 as a hybrid interface, add it to VLAN 4 in untagged mode, and retain the default PVID.
  • C. Configure GE1/0/3 of SW2 as a trunk interface, configure it to allow packets from VLAN 4 to pass through, and set its PVID to VLAN 4.
  • D. Configure GE1/0/3 of SW1 as a trunk interface, configure it to allow packets from VLAN 2 and VLAN
    3 to pass through, and set its PVID to VLAN 4.

答案：A,C

解題說明：
PC1 and PC2 are in different VLANs on SW1, while PC3 is in VLAN 4 on SW2. To allow traffic from VLAN 2 and VLAN 3 users to reach PC3 through the inter-switch link, SW1 must be able to send frames from PC1 and PC2 toward SW2 in a form that SW2 can place into VLAN 4.
Option B is valid because a hybrid interface on SW1 can send frames from VLAN 2 and VLAN 3 untagged , and setting the PVID to VLAN 4 allows untagged inbound frames on the peer side to be associated appropriately when matched with the SW2 configuration. Option C is also valid because configuring SW2's GE1/0/3 as a trunk allowing VLAN 4 and setting its PVID to VLAN 4 means untagged frames arriving from SW1 are treated as belonging to VLAN 4 and can then be forwarded to PC3 through its access interface.
Option A is incomplete because only configuring SW2 does not solve the VLAN handling on SW1. Option D is incorrect because a trunk on SW1 would send VLAN 2 and VLAN 3 frames tagged, which would not match the VLAN 4-only expectation on SW2 in this scenario.


問題 #51
In the WAC + Fit AP networking, an AP fails to go online. The output of the display ap all command run on the WAC is shown below. According to the command output, which of the following is the possible cause of the AP's failure to go online?

  • A. The AP fails to initialize the configuration.
  • B. The AP fails the authentication.
  • C. The AP's software version does not match the WAC's software version.
  • D. The AP is in the blacklist.

答案：C

解題說明：
The correct answer is C. In the command output, the AP state is shown as ver-mismatch. This state directly indicates a version mismatch between the AP and the WAC. In Huawei WLAN deployment, a Fit AP must use a software version that is compatible with the WAC version. If the versions do not match, the AP may be discovered by the WAC and appear in the AP list, but it cannot successfully complete the online process.
Option A is incorrect because blacklist-related failures are displayed with blacklist-related status information, not ver-mismatch. Option B is also incorrect because authentication failures normally generate authentication- related fault indications. Option D is incorrect because configuration initialization failure would not be identified by the specific ver-mismatch state.
HCIA-Datacom troubleshooting knowledge emphasizes reading AP online states carefully. Common causes of AP online failure include IP address acquisition failure, CAPWAP tunnel establishment failure, insufficient licenses, authentication problems, and version mismatch. When the state explicitly shows ver-mismatch, the troubleshooting direction is clear: check AP and WAC software compatibility and upgrade or align the software version as needed.


問題 #52
If the neighbor relationship between R1 and R2 has reached the Full state in OSPF, which of the following statements are true? (Select all that apply)

  • A. R1 and R2 use the same process ID.
  • B. R1 and R2 have the same LSDB in the same area.
  • C. R1 and R2 have different router IDs.
  • D. R1 and R2 belong to the same area.

答案：B,C,D

解題說明：
When two OSPF routers reach the Full state, it means that adjacency establishment has been successfully completed and the routers have synchronized the necessary link-state information for that area. For this to happen, the two routers must have different router IDs, so option A is correct. They must also belong to the same OSPF area on the interfaces used to form the adjacency, making option B correct. Once adjacency reaches Full state, the routers have synchronized their link-state databases for that area, so option D is also correct.
Option C is incorrect because the OSPF process ID is only locally significant on a device. Two neighboring routers do not need to use the same process ID to establish adjacency. HCIA-Datacom teaches that OSPF neighbor formation depends on matching parameters such as area ID, network type, hello/dead timers, authentication settings, and subnet consistency, but not on the locally configured process number. This question is important because many learners mistakenly believe the process ID must match between devices, while in fact OSPF uses protocol parameters exchanged in packets rather than local process labels to form neighbor relationships.


問題 #53
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?

  • A. 10.2.1.1
  • B. 10.0.1.1
  • C. 10.3.1.1
  • D. 10.1.1.1

答案：A

解題說明：
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.


問題 #54
Which of the following IPv6 addresses is a link-local address ?

  • A. FC00::FA63:DBFF:FE9E:10
  • B. FE80::FA63:DBFF:FE9E:10
  • C. 2001::FA63:DBFF:FE9E:10
  • D. FD00::FA63:DBFF:FE9E:10

答案：B

解題說明：
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.
