問題 #77
On the network shown in the figure, STP is enabled on all devices. The bridge priorities and MAC addresses of two switches are shown in the figure. Other parameters retain the default values.
When GE1/0/1 of SW1 fails and once the network is stable, GE1/0/2 of SW2 becomes the designated port.
答案：A
解題說明：
SW1 is the root bridge because both switches have the same priority and SW1 has the lower MAC address. Therefore, all active ports on SW1 are designated ports. On SW2, the port connected to SW1 is selected as the root port.
When GE1/0/1 of SW1 fails, only the remaining link between SW1 and SW2 stays active. In this case, SW1 still remains the root bridge, so its connected interface remains the designated port, while SW2's corresponding interface becomes the root port. Therefore, GE1/0/2 of SW2 does not become a designated port, making the statement false.
問題 #78
FILL BLANK
On the OSPF network shown in the figure, S1 is a Layer 2 switch. A total of_____DRs will be elected on this network. (Enter only digits.)
答案：
解題說明：
1
Explanation:
A DR election occurs on each OSPF broadcast multi-access segment. In this topology, R1, R2, and R3 are connected through the Layer 2 switch S1, forming a single broadcast domain, so only one DR is elected there. The link between R3 and R4 is a point-to-point connection, which does not require DR election. Therefore, only one DR exists in the entire network.
問題 #79
Network administrators need to manage and maintain devices on the campus network. Which of the following protocols cannot modify device configurations, such as interface IP addresses, device names, and so on?
答案：B
解題說明：
The protocol that cannot directly modify device configurations such as interface IP addresses or device names is SFTP , so option C is correct. SFTP is a secure file transfer protocol that runs over SSH and is mainly used to upload, download, and manage files between a client and a network device. It is commonly used for tasks such as transferring configuration files, system software, patches, or log files, but it does not itself provide an interactive or structured configuration modification mechanism.
By contrast, STelnet allows secure remote CLI login, through which an administrator can directly enter commands to change device settings. NETCONF is specifically designed for network configuration management and can modify configurations in a structured manner. SNMP can also modify certain managed object values through write operations when permissions and MIB support allow it, although in practice it is used more often for monitoring. HCIA-Datacom distinguishes between management-plane protocols based on their roles: interactive access, structured configuration, monitoring, and file transfer. This question checks whether the learner can identify SFTP as a file transfer tool rather than a direct configuration protocol.
問題 #80
FILL BLANK
If a gateway router wants its connected IPv6 terminals to obtain IPv6 addresses through SLAAC, it must set the M-bit in RA messages to _______. (Enter only digits.)
答案：
解題說明：
0
Explanation:
For SLAAC (Stateless Address Autoconfiguration), the router advertisement message must indicate that no DHCPv6 stateful configuration is required. This is done by setting the M-bit (Managed flag) to 0, which tells hosts to configure their IPv6 addresses using SLAAC only.
問題 #81
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 Destinations : 10 Routes : 10 Destination/Mask Proto Pre Cost Flags NextHop Interface
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
答案：A
解題說明：
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.
