Network segmentation provides which of the following benefits?

A.
Security through isolation

B.
Link aggregation

C.
Packet flooding through all ports

D.
High availability through redundancy

Explanation:
Network segmentation in computer networking is the act or profession of splitting a computer network into
subnetworks, each being a network segment. Advantages of such splitting are primarily for boosting
performance and improving security through isolation.
Advantages of network segmentation:
Improved security: Broadcasts will be contained to local network. Internal network structure will not be visible
from outside
Reduced congestion: Improved performance is achieved because on a segmented network there are fewer
hosts per subnetwork, thus minimizing local traffic
Containing network problems: Limiting the effect of local failures on other parts of network
