ITPEC FE Morning October 2023 Question 42
ITPEC FE Morning October 2023 — Question 42 of 80
VPN (Virtual Private Network) — secure remote access to a corporate network over the Internet.
A VPN creates an encrypted tunnel through public/insecure networks (e.g., hotel Wi-Fi, coffee shop hotspots), allowing mobile workers to safely access internal corporate resources as if they were on-site.
Why not others:
- (a) DMZ — a network segment between the internal network and the Internet where public-facing servers (web, mail) are placed. It isolates external traffic, not provides remote access.
- (b) SNMP — a protocol for monitoring and managing network devices (routers, switches). It has nothing to do with secure remote access.
- (c) VoIP — a technology for making voice calls over the Internet (e.g., Skype, Zoom). Unrelated to secure network access.
Key rule: VPN = encrypted tunnel for secure remote access over untrusted networks.
