CompTIA Project+ (PK0-005)Basics of IT and GovernanceEasy
A project manager is overseeing the deployment of a new internal document management system. The system will store sensitive company intellectual property. Which of the following IT infrastructure components is primarily responsible for securely segregating network traffic to prevent unauthorized access between different departments using the same physical network?
- AFirewall
- BLoad Balancer
- CSwitch
- DRouter
Show answer & explanationAnswer & explanation
Correct answer: A. Firewall
A firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. It creates a barrier between a trusted internal network and untrusted external networks, such as the Internet, or can segment internal networks.
Why the other options are wrong
- B. A load balancer distributes network traffic across multiple servers to ensure high availability and performance, not for security segregation.
- C. A switch connects devices within a local area network (LAN) but does not inherently provide security segregation between different logical segments.
- D. A router directs network traffic between different networks but doesn't primarily segregate traffic based on security policies.
