質問 # 98
FTP allows users to remotely log in to a network device to manage configuration files (such as uploading and downloading files) and modify configurations (such as renaming the device and configuring an IP address).
正解：A
解説：
FTP is used only for file transfer operations such as uploading and downloading configuration or software files. It does not provide remote command-line access for device management or allow direct configuration changes like renaming devices or configuring IP addresses. Those tasks require management protocols such as SSH or Telnet.
質問 # 99
On a small WLAN shown in the figure, SW2 acts as a DHCP server to assign IP addresses to STAs, and the user data forwarding mode is direct forwarding. Which of the following traffic paths is used for a STA accessing the Internet after connecting to the WLAN through AP1?
正解：D
解説：
In direct forwarding mode, user data is forwarded directly from the AP through the wired network to the upstream network without passing through the WAC. After the STA connects to AP1, traffic follows AP1 → SW1 → SW2 → Internet. The WAC is only used for control and management functions, not for data forwarding, so it is not in the user data path.
質問 # 100
On the network shown in the figure, the administrator creates Eth-Trunk 1 in manual mode on SW1 and SW2, and adds GE1/0/1 and GE1/0/2 on both switches to the Eth-Trunk. After the administrator runs the display interface brief command on SW1, the administrator finds that GE1/0/1 is Up and GE1/0/2 is Down. Which of the following statements is true about this scenario?
正解：B
解説：
For an Eth-Trunk operating in manual load-balancing mode, the logical Eth-Trunk interface can remain Up as long as at least one member link is operational and properly added to the trunk.
Therefore, if GE1/0/1 is Up and GE1/0/2 is Down, Eth-Trunk 1 can still stay Up, making option A correct.
質問 # 101
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?
正解：A
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.
Option A is false because RADIUS does support accounting , and UDP port 1813 is commonly used for that purpose. Option B is false because a separate authorization server IP is not strictly required in this context; RADIUS can carry authorization attributes together with authentication/accounting processing depending on server behavior and device configuration. Option C is false because standard RADIUS communication uses UDP , not TCP, with authentication typically on port 1812 and accounting on 1813 . HCIA-Datacom teaches domain-based AAA processing as a key concept, where the user name suffix determines which authentication, authorization, and accounting policies are applied on the NAS device.
質問 # 102
The MAC address table of SW1 is shown in the figure. If SW1 receives a data frame with the destination MAC address 0050-5600-0003 from PC1, through which of the following interfaces does SW1 send the data frame?
正解：A、B、D
解説：
The MAC address table in the exhibit contains learned entries for 0050-5600-0001 on GE1/0/1 and 0050-
5600-0002 on GE1/0/2, but there is no entry for destination MAC 0050-5600-0003. A frame arriving from PC1 on GE1/0/1 with an unknown unicast destination is therefore flooded within the VLAN. Huawei Ethernet switching behavior sends the unknown unicast frame through all other eligible Layer 2 interfaces in that VLAN, while never sending it back through the ingress interface. In the shown topology, the remaining interfaces are GE1/0/2, GE1/0/3, and GE1/0/4. Consequently, the frame is sent through options A, D, and B respectively. GE1/0/1, option C, is excluded because it is the ingress interface from which SW1 received the frame. If SW1 later learns 0050-5600-0003 on a specific port, subsequent unicast frames can be forwarded only through that learned port. For the empty destination entry shown, the verified answer is A, B, and D.
