A company’s legacy server requires administration using Telnet. Which of the following protocols could be used
to secure communication by offering encryption at a lower OSI layer? (Choose two.)
Telnet supports IPv6 connections.
IPv6 is the communications protocol that provides an identification and location system for computers on
networks and routes traffic across the Internet. IPsec is a protocol suite for securing Internet Protocol (IP)
communications by authenticating and encrypting each IP packet of a communication session. IPsec is a
compulsory component for IPv6.
IPsec operates at Layer 3 of the OSI model, whereas Telnet operates at Layer 7.
