SSCP Practice Question: Ensure that employees connecting from home use a…
A company wants to ensure that employees connecting from home use a secure tunnel to access internal resources. Which protocol should be implemented?
⚠ Common exam trap
ISC2 often tests the distinction between SSH (a secure remote administration tool) and SSL/TLS VPN (a full remote access VPN solution), leading candidates to mistakenly choose SSH because they know it provides encryption, without realizing it does not create a comprehensive network tunnel for all internal resource access.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SSL/TLS VPN
An SSL/TLS VPN creates an encrypted tunnel over HTTPS (port 443) between the remote user's browser or client and the corporate VPN gateway, securing all traffic to internal resources. This is the standard solution for remote access VPNs because it uses ubiquitous SSL/TLS protocols, avoids the need for IPsec client software, and can traverse firewalls and NAT devices easily.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
SFTP
Why it's wrong here
SFTP is for secure file transfer, not for general network access.
- ✗
Telnet
Why it's wrong here
Telnet is an unencrypted protocol and not suitable for secure remote access.
- ✗
SSH
Why it's wrong here
SSH provides secure remote terminal access, not a general VPN tunnel for all applications.
- ✓
SSL/TLS VPN
Why this is correct
A SSL/TLS VPN creates an encrypted tunnel for remote users to access internal resources securely.

VPN Protocol Comparison
| Protocol | Port | Encryption | Authentication | Use Case |
|---|---|---|---|---|
| IKEv2 / IPsec | UDP 500 / 4500 | AES-256 | Certificates / PSK | Site-to-site & remote access |
| SSL / TLS VPN | TCP 443 | TLS 1.3 | Certificates / MFA | Clientless remote access |
| L2TP / IPsec | UDP 1701 | AES (IPsec) | PSK / Certificates | Legacy remote access |
| WireGuard | UDP 51820 | ChaCha20 | Public keys | Modern high-performance VPN |
| PPTP | TCP 1723 | MPPE (weak) | MS-CHAPv2 | Legacy — avoid in production |
PPTP is considered insecure. IKEv2/IPsec and SSL VPN are the current recommended options.
