100-160 Question 78
Single answerA cybersecurity technician is troubleshooting a security issue involving an organization's network traffic. The network includes routers, firewalls, and switches. The technician determines that a device is not forwarding traffic between subnetworks correctly. Which network infrastructure component is most likely causing this issue?
- A
Router
- B
Firewall
- C
Switch
- D
Access Point
Show answer and explanation
Correct answer: A
Explanation
In a network infrastructure, routers are used to forward traffic between different subnetworks. If the issue involves a failure to forward traffic between subnetworks, the router is the most likely component at fault. Other components, such as switches, firewalls, and access points, do not perform the specific function of routing traffic between subnetworks.
- A. Correct.
Routers are responsible for forwarding traffic between different subnetworks. If a router is not functioning correctly, it can prevent communication between subnetworks, making it the most likely cause in this scenario.
- B. Incorrect.
Firewalls are primarily used for traffic filtering and security enforcement based on rules. While a misconfigured firewall can block traffic, it is not responsible for routing traffic between subnetworks.
- C. Incorrect.
Switches operate within a single local network and are used to forward traffic between devices within the same subnet. They do not handle traffic between different subnetworks.
- D. Incorrect.
Access points are used to provide wireless connectivity to devices. They do not handle routing traffic or segmenting subnetworks.
