- A
Configure a direct RDP connection using the user's home IP address.
Why wrong: Direct RDP requires a static IP or dynamic DNS, and exposes the office computer to the internet, which is insecure.
- B
Set up a Virtual Private Network (VPN) client on the user's laptop to connect to the office network.
A VPN client works with any internet connection, regardless of IP address, and provides encrypted access to the office network.
- C
Use a remote desktop gateway that requires a static IP on the user's end.
Why wrong: Remote Desktop Gateway can work with dynamic IPs, but it still requires the user to connect to the gateway, which is less straightforward than a VPN.
- D
Email the file to the user as an attachment.
Why wrong: Emailing files is not a remote access technology and poses security risks; it also does not address the scenario of needing ongoing access.
Quick Answer
The answer is to set up a Virtual Private Network (VPN) client on the user’s laptop to connect to the office network. A VPN creates an encrypted tunnel that secures all data traveling between the remote device and the office, making the user’s dynamic IP address irrelevant because the connection is authenticated and encrypted at the network layer. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding that VPNs are the standard solution for secure remote access over untrusted networks like hotel Wi-Fi, regardless of IP address changes. A common trap is confusing VPNs with Remote Desktop Protocol (RDP), but RDP alone lacks encryption and exposes the office computer directly to the internet. Remember the memory tip: “VPN wraps your data in a secure tunnel, so your IP can change but your connection stays safe.”
220-1102 Remote Access Technologies Practice Question
This 220-1202 practice question tests your understanding of remote access technologies. 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 user is traveling and needs to access a file on their office computer. They have a dynamic IP address at the hotel. Which remote access technology should the technician recommend for a secure connection?
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
Set up a Virtual Private Network (VPN) client on the user's laptop to connect to the office network.
Option B is correct because a VPN client creates an encrypted tunnel between the user's laptop and the office network, allowing secure access to files regardless of the user's dynamic IP address. VPNs authenticate the user and encrypt all traffic, protecting data over untrusted networks like hotel Wi-Fi.
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.
- ✗
Configure a direct RDP connection using the user's home IP address.
Why it's wrong here
Direct RDP requires a static IP or dynamic DNS, and exposes the office computer to the internet, which is insecure.
- ✓
Set up a Virtual Private Network (VPN) client on the user's laptop to connect to the office network.
Why this is correct
A VPN client works with any internet connection, regardless of IP address, and provides encrypted access to the office network.

- ✗
Use a remote desktop gateway that requires a static IP on the user's end.
- ✗
Email the file to the user as an attachment.
Why it's wrong here
Emailing files is not a remote access technology and poses security risks; it also does not address the scenario of needing ongoing access.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that remote access requires a static IP or that direct RDP is acceptable, but the key is that a VPN handles dynamic IPs and provides encryption, which is essential for secure remote access over public networks.

Detailed technical explanation
How to think about this question
VPNs use protocols like IPsec or SSL/TLS to establish a secure tunnel; for example, an SSL VPN can run over port 443, making it difficult to block on restrictive hotel networks. The VPN client negotiates encryption keys and authenticates via certificates or credentials, ensuring that even if the user's IP changes, the connection remains secure and the user appears to be on the office LAN.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- 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.
