Question 581 of 750

Remote Access Technologies →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the VPN client is configured for split tunneling, and the file server’s IP range is not in the allowed routes. This is correct because split tunneling directs only specific corporate traffic through the encrypted VPN tunnel, while all other traffic—like general internet browsing—goes directly to the user’s local gateway. If the file server’s subnet is not listed in those allowed routes, traffic to it bypasses the VPN entirely, making the internal resource unreachable even though internet access works fine. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of VPN routing logic, and a common trap is assuming the VPN is broken or the server is down, when the real issue is a missing route. A helpful memory tip: think of split tunneling as a selective bridge—if the destination isn’t on the bridge’s map, you can’t cross it.

220-1202 Remote Access Technologies Practice Question

This 220-1202 practice question tests your understanding of remote access technologies. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 reports that they cannot connect to the company's internal file server from home using the provided VPN client. They can access the internet without issues. Which of the following is the most likely cause of this problem?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

A
The user's home router is blocking VPN traffic on port 443.
Why wrong: While port blocking can occur, the user can access the internet, so the VPN connection itself is likely established. The issue is routing, not connectivity.
B
The VPN client is configured for split tunneling, and the file server's IP range is not in the allowed routes.
Split tunneling routes only specific traffic through the VPN. If the file server's subnet is omitted, the user cannot reach it, even though the VPN is connected.
C
The file server is powered off or experiencing a hardware failure.
Why wrong: A hardware failure would affect all users, not just this remote user, and does not explain why internet access works.
D
The user's VPN client software is outdated and needs to be reinstalled.
Why wrong: An outdated client might cause connection failures, but the user can connect to the VPN (since internet works), so the client is functioning.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The VPN client is configured for split tunneling, and the file server's IP range is not in the allowed routes.

Split tunneling allows the VPN client to route only specific traffic (e.g., corporate subnets) through the encrypted tunnel, while all other traffic goes directly to the internet. If the file server's IP range is not included in the allowed routes, traffic to that server will bypass the VPN and be sent unencrypted to the user's local gateway, which cannot reach the internal server. This matches the symptom: internet works, but the file server is unreachable.

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

The trap here is that candidates often assume any remote access issue is due to firewall blocking or server failure, overlooking the specific split tunneling misconfiguration that allows internet but blocks internal resources.

Detailed technical explanation

How to think about this question

Split tunneling is configured via routing tables pushed by the VPN server (e.g., using DHCP option 121 or static routes). The VPN client adds these routes to the local routing table with a higher metric, so traffic to the corporate subnet goes through the virtual adapter (e.g., tun0), while all other traffic uses the default gateway. A common misconfiguration is omitting the file server's subnet from the route list, causing traffic to be sent unencrypted to the user's ISP, which cannot route to the private IP range (e.g., 10.0.0.0/8).

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 network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.
