質問 # 414
A network technician needs to resolve some issues with a customer ' s SOHO network. The customer reports that some of the PCs are not connecting to the network, while others appear to be working as intended.
INSTRUCTIONS
Troubleshoot all the network components.
Review the cable test results first, then diagnose by clicking on the appropriate PC, server, and Layer 2 switch.
Identify any components with a problem and recommend a solution to correct each problem.
If at any time you would like to bring back
the initial state of the simulation, please
click the Reset All button.
正解：
解説：
See the answer and solution below:
Explanation:
A computer network diagram with many boxes and text AI-generated content may be incorrect.

A network architect needs to create a wireless field network to provide reliable service to public safety vehicles. Which of the following types of networks is the best solution?
正解：D
解説：
A mesh network is the best solution for providing reliable wireless service to public safety vehicles. In a mesh network, each node (vehicle) can connect to multiple other nodes, providing multiple paths for data to travel. This enhances reliability and redundancy, ensuring continuous connectivity even if one or more nodes fail. Mesh networks are highly resilient and are well-suited for dynamic and mobile environments such as public safety operations.Reference: CompTIA Network+ study materials.
質問 # 416
A network technician is terminating a cable to a fiber patch panel in the MDF. Which of the following connector types is most likely in use?
正解：D
解説：
In a fiber patch panel, the SC (Subscriber Connector or Standard Connector) is commonly used because of its push-pull design and reliability in enterprise environments.
Breakdown of Options:
A . F-type - Used for coaxial cables (e.g., cable TV), not fiber.
B . RJ11 - Used for telephone lines, not fiber.
C . BNC - Used for coaxial connections, not fiber.
D . SC - ✅ Correct answer. A standard fiber optic connector used in patch panels.

SIMULATION
A network technician was recently onboarded to a company. A manager has tasked the technician with documenting the network and has provided the technician With partial information from previous documentation.
Instructions:
Click on each switch to perform a network discovery by entering commands into the terminal. Fill in the missing information using drop-down menus provided.
正解：
解説：
See the Explanation for detailed information on this simulation
Explanation:
(Note: Ips will be change on each simulation task, so we have given example answer for the understanding) To perform a network discovery by entering commands into the terminal, you can use the following steps:
Click on each switch to open its terminal window.
Enter the command show ip interface brief to display the IP addresses and statuses of the switch interfaces.
Enter the command show vlan brief to display the VLAN configurations and assignments of the switch interfaces.
Enter the command show cdp neighbors to display the information about the neighboring devices that are connected to the switch.
Fill in the missing information in the diagram using the drop-down menus provided.
Here is an example of how to fill in the missing information for Core Switch 1:
The IP address of Core Switch 1 is 192.168.1.1.
The VLAN configuration of Core Switch 1 is VLAN 1: 192.168.1.0/24, VLAN 2: 192.168.2.0/24, VLAN 3: 192.168.3.0/24.
The neighboring devices of Core Switch 1 are Access Switch 1 and Access Switch 2.
The interfaces that connect Core Switch 1 to Access Switch 1 are GigabitEthernet0/1 and GigabitEthernet0/2.
The interfaces that connect Core Switch 1 to Access Switch 2 are GigabitEthernet0/3 and GigabitEthernet0/4.
You can use the same steps to fill in the missing information for Access Switch 1 and Access Switch 2.
質問 # 418
Which of the following attacks involves overwhelming a switch's CAM table with spoofed MAC addresses, causing the switch to flood traffic to all ports?
正解：B
解説：
MAC flooding overwhelms a switch's CAM (Content Addressable Memory) table by sending a flood of frames with spoofed MAC addresses. Once the CAM table overflows, the switch cannot learn legitimate MAC addresses and defaults to flooding all frames out all ports, effectively turning it into a hub. This allows an attacker to capture traffic not originally destined for their port.
* A. ARP poisoning corrupts ARP tables to redirect traffic but does not overflow the CAM table.
* B. Evil twin is a wireless rogue AP attack, unrelated to switch behavior.
* D. DNS spoofing redirects domain queries, not Layer 2 switching.
References (CompTIA Network+ N10-009):
* Domain: Network Security - Switch security, CAM table attacks, MAC flooding.
