Huawei HCIA-Datacom V2.0 認定 H12-811_V2.0 試験問題 (Q99-Q104):

質問 # 99
Which of the following IPv6 addresses is a link-local address?

A. FC00::FA63:DBFF:FE9E:10
B. FD00::FA63:DBFF:FE9E:10
C. 2001::FA63:DBFF:FE9E:10
D. FE80::FA63:DBFF:FE9E:10

正解：D

解説：
In IPv6, link-local addresses use the prefix FE80::/10. These addresses are automatically generated or configured for communication on the local link only and are not routed across Layer
3 boundaries. Therefore, among the given options, FE80::FA63:DBFF:FE9E:10 is the correct link- local address, making option C correct.

質問 # 100
After the root bridge is elected on an STP network, which of the following parameters may be compared by ports on non-root bridge nodes to elect the root port? (Select all that apply)

A. Root path cost (RPC)
B. PID of a port on the device that sends BPDUs
C. PID of a port on the local device
D. BID of the device that sends BPDUs

正解：A、B、C、D

解説：
On a non-root bridge, the root port is the port that receives the best BPDU toward the root bridge.
STP selects the root port by comparing several parameters in order. The first important parameter is the root path cost (RPC), so option B is correct. If multiple ports have the same RPC, the switch then compares the bridge ID (BID) of the upstream device sending the BPDU, making option C correct. If those are still equal, the switch compares the port ID (PID) of the upstream sending port, so option D is also correct.
If all of those values remain identical from the switch's perspective, the device can finally compare the local port ID to determine which local interface becomes the root port, so option A is also correct. HCIA-Datacom teaches this comparison logic as part of STP election rules. The process ensures deterministic selection of a single root port on every non-root switch.
Understanding the comparison sequence is essential for predicting STP topology behavior and for influencing port roles through path cost tuning or bridge-priority adjustments during campus network design and troubleshooting.

質問 # 101
Which of the following statements are true about the Python code shown below? (Select all that apply) import paramiko import time ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect('192.168.1.254', username='python', password='Huawei@123') channel = ssh.invoke_shell() channel.send('screen-length 0 temporary\n') time.sleep(1) output = channel.recv(65535).decode('utf-8') print(output) ssh.close()

A. import paramiko and import time are used to import the modules required by the code.
B. channel = ssh.invoke_shell() is used to create an interactive shell session.
C. ssh.close() is used to terminate the SSH connection.
D. ssh.connect('192.168.1.254', username='python', password='Huawei@123') is used to set up a connection with the device whose IP address is 192.168.1.254.

正解：A、B、C、D

解説：
All four statements are correct. The code uses the Paramiko library to automate SSH login to a network device. import paramiko and import time load the Python modules required for SSH communication and delay control, so option C is correct. The statement ssh = paramiko.SSHClient() creates an SSH client object, and ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) allows the client to accept an unknown host key automatically in this example scenario.
The command ssh.connect('192.168.1.254', username='python', password='Huawei@123') establishes an SSH connection to the target device, so option B is correct. Then channel = ssh.invoke_shell() opens an interactive shell channel, which is commonly used to send CLI commands and receive output just as an administrator would in a terminal session, making option D correct. The command channel.send('screen-length 0 temporary\n') disables page-by-page output for the current session, which is useful in network automation. Finally, ssh.close() closes the SSH session and releases the connection, so option A is correct. HCIA-Datacom automation knowledge often uses Paramiko examples to demonstrate basic Python-based device O&M.

質問 # 102
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).

A. TRUE
B. FALSE

正解：B

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 # 103
UDP does not guarantee data transmission reliability and does not provide packet sorting and traffic control functions. It is suitable for the traffic that has low requirements for data transmission reliability, but high requirements for the transmission speed and delay.

A. TRUE
B. FALSE

正解：A

解説：
UDP (User Datagram Protocol) is a connectionless protocol that does not provide reliability, packet sequencing, or traffic control. These features are usually managed by TCP, which is used for applications requiring reliable data transmission. UDP's design makes it suitable for real-time applications, such as video streaming or VoIP, where speed and low latency are prioritized over reliability.
