Which two remote access methods are secure because they encrypt traffic? (Choose two.)

The correct answer is B. SSH C. VPN. SSH (B) and VPN (C) are correct because both protocols are designed with encryption as a core feature. SSH (Secure Shell) encrypts all data transmitted between client and server, making it ideal for secure remote terminal access and file transfers. A VPN (Virtual Private…

Explanation

SSH (B) and VPN (C) are correct because both protocols are designed with encryption as a core feature. SSH (Secure Shell) encrypts all data transmitted between client and server, making it ideal for secure remote terminal access and file transfers. A VPN (Virtual Private Network) creates an encrypted tunnel over a public network, securing all traffic passing through it regardless of the application.

Why the distractors fail:

  • Telnet (D) and rlogin (E) transmit data - including credentials - in plaintext, making them trivially interceptable via packet sniffing. They are considered legacy protocols and should never be used over untrusted networks.
  • iPrac-AH (A) is a distractor; "AH" (Authentication Header) is part of IPsec and provides authentication and integrity but not confidentiality (encryption). The "iPrac" prefix appears fabricated for this question.

Memory tip: Think "SSH and VPN = Secure Vault" - both create a protected container around your data. Any protocol that predates the modern security era (Telnet, rlogin) is almost certainly unencrypted and wrong on exam questions about security.
