The answer is to enable a VPN server on the firewall. A VPN server creates an encrypted tunnel between a remote user and the internal network, ensuring that all data transmitted over the internet remains confidential and secure from eavesdropping. This is the standard method for providing firewall VPN server remote access, as it authenticates users and protects sensitive company resources. On the CompTIA A+ Core 2 220-1202 exam, this concept tests your understanding of secure remote connectivity versus less secure alternatives like port forwarding or plain Remote Desktop Protocol. A common trap is confusing a VPN server with a simple port forward—remember that a VPN adds encryption and authentication, not just access. For a memory tip, think of the VPN as a “secure tunnel” through the firewall: it wraps your data in a protective layer before it travels across the public internet.
220-1102 Logical Security Concepts Practice Question
This 220-1202 practice question tests your understanding of logical security concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is configuring a new firewall for a small office. They need to allow remote employees to securely access the internal network. Which technology should be enabled on the firewall?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
VPN server
A VPN creates an encrypted tunnel between a remote user and the internal network, ensuring secure access. This is the standard method for remote employees to connect safely.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Port forwarding
Why it's wrong here
Port forwarding exposes internal services to the internet without encryption, which is not secure for remote access.
✗
VPN passthrough
Why it's wrong here
VPN passthrough allows existing VPN connections to traverse the firewall but does not create a VPN server.
✓
VPN server
Why this is correct
A VPN server on the firewall enables remote users to establish encrypted connections to the internal network.

✗
DMZ
Why it's wrong here
A DMZ hosts public-facing services and does not provide secure remote access to the internal network.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
