Which of the following is the BEST method of logical network segmentation?

VLAN tagging and isolationis the best method forlogical network segmentationbecause:

Network Segmentation:VLANs logically separate network traffic within the same physical infrastructure.

Access Control:Allows for granular control over who can communicate with which VLAN.

Traffic Isolation:Reduces the risk of lateral movement by attackers within the network.

Efficiency:More practical and scalable than physical separation.

Incorrect Options:

A. Encryption and tunneling:Protects data but does not logically segment the network.

B. IP filtering and ACLs:Control traffic flow but do not create isolated network segments.

D. Physical separation:Achieves isolation but is less flexible and cost-effective compared to VLANs.

Exact Extract from CCOA Official Review Manual, 1st Edition:

Refer to Chapter 5, Section "Network Segmentation Techniques," Subsection "VLAN Implementation" - VLANs are the most efficient way to achieve logical separation and isolation.
