Question 1

Making a call on a landline telephone is a type of network communication.



Answer : A

Making a call on a landline telephone involves network communication. Though it uses a traditional telephone network (Public Switched Telephone Network, PSTN), the process of sending and receiving voice data through a wired system qualifies as network communication. The voice signals are converted into electrical signals, transmitted over the network, and then converted back into voice signals on the receiving end .


Question 2

When forwarding a data packet, a router needs to change the destination IP address of the packet.



Answer : B

How Routers Handle Packets:

Routers do not change the destination IP address when forwarding packets.

The destination IP remains the same to ensure the packet reaches the intended recipient.

Router's Role:

Routers inspect the destination IP, determine the best path using routing tables, and forward the packet accordingly.

Conclusion:

The destination IP address remains unchanged; hence, the statement is FALSE.


Question 3

What function does Ctrl+Z have in the VRP system?



Answer : C

In Huawei's Versatile Routing Platform (VRP), pressing Ctrl+Z is a shortcut that takes the user from any configuration view directly back to the user view. This command is useful for quickly navigating out of multiple levels of configuration back to the main user prompt. This feature is part of the VRP interface management commands for efficient system navigation.


Question 4

Which of the following is the default port number of the Telnet server?



Answer : D

The default port number for Telnet is 23. This standard port assignment allows Telnet clients to connect to Telnet servers, facilitating remote management and troubleshooting tasks on network devices. Ports are preassigned to services to streamline network communication and reduce conflicts.


Question 5

(Each network device running SNMP runs an agent process locally.)



Answer : A

SNMP Agent Functionality:

Each network device running SNMP includes an agent process that collects and manages information about the device's operations. This process interfaces with the SNMP manager to provide network monitoring and management capabilities.


Question 6

Refer to the following configuration of an interface on a switch. What is the PVID of the interface?

interface GigabitEthernet0/0/1

port hybrid tagged vlan 2 to 3 100

port hybrid untagged vlan 4 6



Answer : D

The PVID (Port VLAN ID) for a hybrid port refers to the VLAN that is assigned to untagged traffic. In this case, VLAN 4 is specified as untagged, making it the PVID for this interface. Traffic received without a VLAN tag is associated with VLAN 4 upon entering the switch.


Question 7

SDN requires the control and forwarding planes to be separated.



Answer : A

Comprehensive Explanation= In Software-Defined Networking (SDN), the control plane (which makes decisions about where to send traffic) is separated from the forwarding plane (which actually moves packets to their destinations). This separation allows for centralized control and management of the network, enabling programmability and greater flexibility. SDN controllers manage the control plane, while individual switches or routers handle the forwarding of data.
