220-1201 Practice Question: Allow employees to securely access the corporate…
A company wants to allow employees to securely access the corporate network from home using their laptops. Which network service should be deployed to provide encrypted remote access?
⚠ Common exam trap
CompTIA A+ often tests the misconception that port forwarding alone provides secure remote access, but candidates must remember that port forwarding lacks encryption and authentication, making it insecure for remote connectivity.
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
C is correct because a Virtual Private Network (VPN) creates an encrypted tunnel between the employee's laptop and the corporate network, typically using protocols such as IPsec or TLS. This ensures that all data transmitted over the public internet is confidential and integrity-protected, meeting the requirement for secure remote access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
DHCP
Why it's wrong here
DHCP assigns IP addresses but does not provide any security or encryption for remote connections.
- ✗
DNS
Why it's wrong here
DNS resolves names to IPs and is not used for secure remote access.
- ✓
VPN
Why this is correct
VPN establishes an encrypted connection over the internet, enabling secure remote access to the corporate network.
- ✗
Port forwarding
Why it's wrong here
Port forwarding exposes internal services but does not provide encryption or authentication for remote users.
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.
