ITPEC IP October 2023 Question 30
ITPEC IP October 2023 — Question 30 of 100
A remote-access VPN uses authentication and encryption to create a secure logical connection across the public Internet. Authentication verifies the remote user or device, and encryption protects transmitted data from interception or alteration as it travels between the PC and the workplace network.
Answer (d)
Why not others:
- (a) multiple Internet lines improve redundancy but do not define a VPN
- (b) an Internet VPN does not inherently guarantee maximum delay
- (c) compression may reduce data volume but cannot guarantee minimum bandwidth
Key rule: A VPN provides a protected tunnel over another network; it improves communication security but does not by itself guarantee availability, latency, or bandwidth.
