NEW QUESTION # 62
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()

Answer: A,B,C,D


NEW QUESTION # 63
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()

Answer: A,B,C,D

Explanation:
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.


NEW QUESTION # 64
Both SNMP Trap and Inform Request are used by managed devices to send alarms to the NMS. Inform Request requires an acknowledgment from the NMS, whereas Trap does not.

Answer: B

Explanation:
This statement is true . In SNMP, both Trap and Inform messages are used by managed devices to proactively report alarms or events to the Network Management System (NMS) . However, their reliability behavior is different. A Trap is sent without requiring an acknowledgment from the NMS. Once it is transmitted, the sender does not confirm whether the manager actually received it.
By contrast, an Inform Request requires the NMS to send a response confirming receipt. If the managed device does not receive the acknowledgment within the expected time, it can retransmit the Inform message.
Because of this, Inform is considered more reliable than Trap, although it also introduces slightly more overhead. HCIA-Datacom highlights this difference when explaining SNMP-based monitoring and alarm reporting. In real network O & M scenarios, the choice between Trap and Inform depends on the required balance between reliability and simplicity. This question tests a very standard SNMP knowledge point: Trap is unacknowledged , while Inform is acknowledged . Understanding this distinction helps network engineers choose suitable alarm reporting mechanisms in enterprise monitoring platforms.


NEW QUESTION # 65
When deploying a WLAN with the WAC + Fit AP architecture on a customer's live network, you find that APs fail to go online. Which of the following are possible causes? (Choose all that apply.)

Answer: A,B,D

Explanation:
APs may fail to go online due to issues in IP address acquisition, control connectivity, or CAPWAP configuration. Incorrect DHCP settings can prevent APs from obtaining IP addresses, and an unavailable link between APs and WAC will block CAPWAP establishment. If no CAPWAP address is configured on the WAC, APs cannot discover or establish a control channel to the WAC. AP working mode being Fat is not a typical direct cause of online failure in a Fit AP + WAC deployment, since mode mismatch alone does not inherently block online status if properly converted or managed.


NEW QUESTION # 66
What is the main function of the DNS protocol?

Answer: B

Explanation:
DNS (Domain Name System) is responsible for translating human-readable domain names (like www.example.com) into IP addresses, enabling devices to locate services on a network.
