NEW QUESTION # 70
When a Huawei network device functions as a Telnet server, which of the following are possible causes of a client falling to log in to the Telnet server? (Choose all that apply.)
Answer: A,C,D
Explanation:
A Telnet login failure can occur due to multiple reasons related to reachability, service configuration, or device setup. If the network between the client and the server is unreachable, the TCP-based Telnet session cannot be established. If the user interface (VTY lines) is not configured to allow Telnet access, login attempts will be rejected. Similarly, if the Telnet server function is not enabled on the device, remote Telnet connections cannot be established. The source interface configuration is not required for basic Telnet server functionality, so it is not a common cause of login failure.
NEW QUESTION # 71
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)
Answer: B,C,D
Explanation:
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.
NEW QUESTION # 72
Given the following routing table, what is the source IP address used by R1 when sending an ICMP packet to ping 10.0.3.3?
Answer: B
Explanation:
When R1 sends an ICMP echo request, it selects the outgoing interface based on the routing table. The route to 10.0.3.3 uses the next hop 10.0.23.3 via GE0/0/2. Huawei devices use the IP address of the egress interface as the source IP for locally generated packets. GE0/0/2 has the address 10.0.23.2, so this is used as the source IP.
NEW QUESTION # 73
According to the following routing table, it can be inferred that the IP address of VLANIF 2 on R1 is 10.0.12.1/24.
[R1] display ip routing-table
Proto: Protocol Pre: Preference
Route Flags: R - relay, D - download to fib, T - to vpn-instance, B -
black hole route
Routing Table: public

10.0.12.0/24 Direct 0 0 D 10.0.12.1 Vlanif2
10.0.12.1/32 Direct 0 0 D 127.0.0.1 Vlanif2
10.0.12.255/32 Direct 0 0 D 127.0.0.1 Vlanif2
10.0.21.0/24 Direct 0 0 D 10.0.21.1 Vlanif3
10.0.21.1/32 Direct 0 0 D 127.0.0.1 Vlanif3
10.0.21.255/32 Direct 0 0 D 127.0.0.1 Vlanif3
Answer: B
Explanation:
This statement is true. From the routing table, the entry 10.0.12.0/24 Direct ... NextHop 10.0.12.1 Interface Vlanif2 indicates that the network 10.0.12.0/24 is directly connected through Vlanif2, and the local interface address associated with that directly connected network is 10.0.12.1.
This conclusion is further supported by the host route 10.0.12.1/32 Direct ... 127.0.0.1 Vlanif2, which represents the local IP address of the interface itself. On Huawei devices, when an IP address is configured on an interface, the routing table commonly generates a direct route to the connected network, a host route to the interface IP itself, and sometimes a host route to the broadcast address where applicable in IPv4. Therefore, from the displayed entries, it can indeed be inferred that VLANIF 2 has the IP address 10.0.12.1/24. HCIA-Datacom uses these routing- table characteristics to help learners identify connected interfaces, local addresses, and route origins during troubleshooting and route analysis on routers and Layer 3 switches.
NEW QUESTION # 74
On the network shown in the figure, R1 serves as the gateway for PC2 and PC3, and directly connects to S1 through a physical link. GE1/0/1 on S1 is configured as a trunk interface and permits traffic of VLANs 2 and 3. Its PVID retains the default value. Which of the following statements are true if PC2 and PC3 can communicate with each other? (Select all that apply)
Answer: A,C,D
Explanation:
This scenario describes the classic router-on-a-stick inter-VLAN routing design. A single physical interface on R1 connects to switch S1, and multiple sub-interfaces are created on that physical interface to serve as gateways for multiple VLANs. Therefore, if R1 provides Layer 3 gateway functions for VLAN 2 and VLAN 3, sub-interfaces such as GE0/0/1.2 and GE0/0/1.3 must be configured, so option A is correct.
Because PC2 and PC3 are connected to switch S1, S1 learns their source MAC addresses dynamically and stores them in its MAC address table, making option B correct. R1 receives tagged frames from different VLANs on the trunk link and, through its sub-interfaces, can identify and terminate frames for VLAN 2 and VLAN 3, so option C is also correct.
