質問 # 18
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.
正解：A
解説：
This statement is false . In classic STP, when a non-root switch detects a topology change, it does not continuously send configuration BPDUs upstream to notify the root bridge. Instead, it sends a Topology Change Notification (TCN) BPDU toward the root bridge through its root port. Each upstream switch acknowledges the TCN and forwards it further until it reaches the root bridge.
After the root bridge receives the topology change notification, the root bridge sets the Topology Change (TC) flag in its configuration BPDUs, and those configuration BPDUs are then propagated throughout the network. Therefore, topology-change notification and normal configuration BPDU transmission are different functions. The statement is wrong because it confuses TCN BPDUs with configuration BPDUs , and also inaccurately describes the notification behavior. HCIA-Datacom requires learners to distinguish between these BPDU types and understand how STP reacts to topology changes by accelerating MAC address aging and informing the network through the root bridge. This process helps the Layer 2 topology converge and reduces long-lasting forwarding inconsistencies after a link or port-state change.
質問 # 19
On a switched network, the administrator has completed the VLAN-related configuration shown in the figure on SW1. If the administrator runs the ping 192.168.1.2 command on PC1, the ping will fail.
正解：A
解説：
Both switch ports shown in the exhibit are configured as trunk ports and VLAN 10 is permitted, but the configuration does not change the trunk PVID from its default value of VLAN 1. On Huawei switches, untagged frames received on a trunk interface are associated with the interface PVID. A normal PC sends untagged Ethernet frames, so traffic from both PC1 and PC2 is classified into VLAN 1. VLAN 1 is permitted on a trunk by default unless it is explicitly removed with an undo port trunk allow-pass vlan 1 command. As a result, the two PCs remain in the same Layer 2 broadcast domain through VLAN 1 and can exchange ARP and ICMP traffic. Merely adding VLAN 10 to the allowed VLAN list does not force untagged host traffic into VLAN 10. Therefore, the statement that pinging 192.168.1.2 from PC1 must fail is incorrect. The correct response is FALSE, option B.
質問 # 20
Which of the following information is displayed when an entered command is incomplete on the Versatile Routing Platform (VRP)?
正解：B
質問 # 21
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)
正解：B、C
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.
質問 # 22
An administrator attempts to add the following rule to ACL 2001 on R1:
[R1] acl 2001
[R1-acl4-basic-2001] rule deny tcp destination-port eq telnet source 192.168.1.3 0 destination 192.168.2.0
0.0.0.255
In this case, the rule cannot be configured successfully.
正解：B
解説：
ACL 2001 is a basic IPv4 ACL because Huawei numbered basic ACLs use the range 2000 to 2999. A basic ACL can match relatively simple conditions such as source IP address and an effective time range, but it does not support matching the IP protocol, destination IP address, or TCP/UDP source and destination port numbers. The attempted rule includes tcp, destination-port eq telnet, and a destination network, all of which require an advanced ACL. Huawei advanced ACLs use the 3000 to 3999 range and can match protocol type, source and destination addresses, and Layer 4 port values. Therefore, even after correcting the obvious command typo from ad 2001 to acl 2001, the rule syntax is still incompatible with a basic ACL 2001 and cannot be successfully configured in that ACL view. To implement the intended policy, the administrator should create an advanced ACL and express the TCP Telnet and destination conditions there. Consequently, the statement that the rule cannot be configured successfully is TRUE, option A.
