- A
Configure port forwarding on the main office router for each required service
Why wrong: Port forwarding exposes services directly to the internet, which is insecure and not scalable for multiple users.
- B
Set up a site-to-site VPN between the two offices
A site-to-site VPN provides a secure, encrypted connection between entire networks, allowing seamless access for all users.
- C
Use Remote Desktop for each user to connect to a workstation at the main office
Why wrong: RDP is not designed for network-level access and would require a separate session for each user, which is inefficient and less secure.
- D
Implement a client-to-site VPN for each user
Why wrong: While secure, client-to-site VPNs require individual configuration and management for each user, making it less scalable than a site-to-site solution.
Quick Answer
The answer is a site-to-site VPN, because it creates an encrypted, always-on tunnel between the two office routers, allowing all ten users at the remote office to access main office resources as if they were on the same local network. This method is both more secure and scalable than a client VPN, which would require each user to manually connect their individual device, creating management overhead and potential connectivity gaps. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of network infrastructure versus endpoint solutions; a common trap is choosing client VPN because it sounds user-friendly, but the question specifically asks for a solution that handles multiple users transparently. Remember the memory tip: “Site connects sites, client connects people”—if the goal is to link entire offices, always pick site-to-site.
220-1202 Remote Access Technologies Practice Question
This 220-1202 practice question tests your understanding of remote access technologies. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 tasked with securely connecting a remote office to the main office over the internet. The remote office has 10 users who need access to the same resources as local users. Which of the following remote access methods provides the most secure and scalable solution?
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 site-to-site VPN between the two offices
A site-to-site VPN (often using IPsec or a secure tunnel protocol) creates an encrypted, always-on connection between the two office routers, allowing all 10 users transparent access to the main office resources as if they were on the same LAN. This method is both secure (encrypting all traffic) and scalable (handling multiple users without per-client configuration), making it the best fit for connecting entire networks over the internet.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between site-to-site and client-to-site VPNs, where candidates mistakenly choose client-to-site VPN (Option D) thinking it is more secure per-user, but the question emphasizes 'scalable' and 'connecting a remote office'—a site-to-site VPN is the correct enterprise solution for network-to-network connectivity.
Detailed technical explanation
How to think about this question
A site-to-site VPN typically uses IPsec in tunnel mode with IKEv2 for key exchange, encapsulating entire IP packets within encrypted ESP (Encapsulating Security Payload) headers. This creates a virtual network link between the two offices, allowing broadcast and multicast traffic (if configured) and supporting all protocols without client software. In a real-world scenario, this is ideal for branch offices with multiple users because the VPN gateway handles all encryption/decryption, offloading the work from individual endpoints.
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.
