ITPEC FE Morning October 2021 Question 42
ITPEC FE Morning October 2021 — Question 42 of 80
VLAN for network segmentation — divide a company network into department-level segments.
VLAN (Virtual Local Area Network) logically splits a single physical network into isolated broadcast domains, enabling per-department segmentation without additional hardware.
Why not others:
- (a) DMZ — a buffer zone between internal network and the internet for public-facing servers
- (b) NAT — translates private IP addresses to public; does not segment the network
- (d) VPN — creates encrypted tunnels for remote access; connects networks, not divides them
Key rule: When asked about dividing or segmenting a network by department/function → VLAN.
