200-301 Question 12
Single answerA network engineer is designing a small office network and needs to decide whether to use a Layer 2 switch or a Layer 3 switch. The network requires inter-VLAN routing, scalability for future growth, and efficient traffic management. Which type of switch should the engineer choose and why?
- A
Layer 2 switch because it is sufficient for inter-VLAN routing
- B
Layer 2 switch because it is more cost-effective and supports basic switching functionality
- C
Layer 3 switch because it supports inter-VLAN routing and efficient traffic management
- D
Layer 3 switch because it is specifically designed for wireless network management
Show answer and explanation
Correct answer: C
Explanation
A Layer 3 switch is the appropriate choice for this scenario because it can handle inter-VLAN routing, which is required for communication between VLANs, and offers enhanced traffic management and scalability. Layer 2 switches lack the routing functionality needed to meet these requirements.
- A. Incorrect.
Layer 2 switches do not natively support inter-VLAN routing. They can only handle traffic within the same VLAN unless additional devices, like a router, are used.
- B. Incorrect.
While Layer 2 switches are cost-effective and handle basic switching, they are inadequate for inter-VLAN routing and advanced traffic management required by the scenario.
- C. Correct.
Layer 3 switches are capable of performing inter-VLAN routing and provide routing features, making them ideal for scalability and efficient traffic management in this scenario.
- D. Incorrect.
Layer 3 switches are not specifically designed for wireless network management. Wireless management typically involves access points and wireless controllers.
