FC0-U71 Practice Question: A user wants to securely access company resources…
A user wants to securely access company resources from a remote location over the internet. Which technology should be used?
⚠ Common exam trap
Many exam-takers confuse SSH with a general remote access solution because it provides encryption, but SSH only secures a single terminal session, not full network-layer access to all company resources.
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
✓
VPN
A VPN (Virtual Private Network) creates an encrypted tunnel between the user's device and the company's network over the internet, ensuring confidentiality and integrity of data. This allows remote users to securely access internal resources as if they were directly connected to the corporate LAN. Technologies like IPsec or TLS are commonly used to establish this secure connection.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
HTTP
Why it's wrong here
HTTP is unencrypted and not suitable for secure access.
- ✗
SSH

SSH provides secure command-line access, not full network access.
- ✗
FTP
Why it's wrong here
FTP transfers files in plaintext, not secure.
- ✓
VPN
Why this is correct
VPN encrypts all traffic between the remote user and the corporate network.
Quick reference
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.
