C) Assigning the same subnet to all departments
D) Avoiding VLANs entirely
- (The provided answer is B)
Answer:
Question 1
The correct answer is B) Proper IP address subnetting and allocation.
In a medium-sized campus network, effective subnet planning is critical for efficient use of IP address space, improved network performance, enhanced security, and easier management. Proper subnetting involves dividing a larger network into smaller, logical subnetworks (subnets) based on organizational needs (e.g., by department, building, or function). This allows:
- Better traffic segmentation and reduced broadcast domains.
- Scalable growth and efficient IP utilization (especially with private IPv4 addresses via RFC 1918).
- Integration with VLANs for Layer 2 separation and Layer 3 routing.
- Application of access controls and QoS policies.
Why the other options are incorrect:
- A) Using only public IP addresses: Public IPs are limited and expensive; campus networks typically use private IP addresses with NAT for internet access.
- C) Assigning the same subnet to all departments: This creates a single large broadcast domain, leading to congestion, security risks, and poor manageability.
- D) Avoiding VLANs entirely: VLANs are commonly used with subnetting to provide logical separation without additional physical infrastructure.
Question 2
The provided answer B is correct, as explained above.
