Huawei HCIA-Datacom V2.0 Sample Questions (Q23-Q28):

NEW QUESTION # 23
On the network shown in the figure, all switches run STP. All links have a path cost of 20, and SW1 is the root bridge. What is the root path cost (RPC) of SW4?

Answer: B

Explanation:
The root path cost (RPC) of a switch is the total path cost from that switch to the root bridge along the selected spanning-tree path. Since SW1 is given as the root bridge, its RPC is 0. Each link in the topology has a path cost of 20 . To determine SW4's RPC, you identify the shortest active STP path from SW4 to SW1.
Based on the topology used in the question, SW4 reaches SW1 through a path containing two links .
Therefore, the total root path cost is 20 + 20 = 40 , which makes option B correct. This is a standard STP calculation. HCIA-Datacom uses RPC as one of the main comparison parameters in root-port election on non- root switches. A lower RPC means a better path toward the root bridge. If multiple candidate ports have the same RPC, the switch then compares the sender's bridge ID and port ID. This question checks whether the learner understands that RPC is cumulative across the spanning-tree forwarding path and is not simply the cost of a single directly connected link unless the switch is directly attached to the root bridge.


NEW QUESTION # 24
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?

Answer: D

Explanation:
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.


NEW QUESTION # 25
Which of the following methods of the Python paramiko SSHClient class can be used to send commands to a network device?

Answer: C

Explanation:
In the Paramiko SSHClient class, the method used to execute commands on a remote network device is exec_command(), which sends the command over an established SSH session and returns the output.


NEW QUESTION # 26
On the network shown in the figure, S2 serves as a DHCP server and has four address pools, R1 functions as a DHCP relay agent, and S1 is a DHCP client. Which of the following IPv4 addresses can be assigned to S1 through DHCP?

Answer: B

Explanation:
S1 is a DHCP client and will receive an IP address from the DHCP server S2 via the relay agent R1. The DHCP server has multiple pools, and only the pool matching the client-side network of S1 (192.168.1.0/24) applies. Therefore, the only valid address that can be assigned to S1 must come from the 192.168.1.0/24 subnet. Among the options, only 192.168.1.108/24 belongs to that correct address pool.


NEW QUESTION # 27
Which of the following variables defined in Python code is invalid?

Answer: C

Explanation:
In Python, variable names must follow identifier rules: they cannot start with a digit. The variable
2_r1 is invalid because it begins with the number 2, which violates Python naming conventions.
The other variables are valid because they either start with letters or underscores and follow proper identifier rules.
