The answer is to disable split tunneling, because this setting forces all traffic from the remote device—not just corporate-bound data—to route through the VPN tunnel and into the corporate network. When split tunneling is enabled, internet traffic bypasses the VPN, breaking the security requirement for full traffic inspection and policy enforcement. On the CompTIA A+ Core 2 220-1202 exam, this concept tests your understanding of how VPN protocols enforce security boundaries; a common trap is assuming split tunneling is the default or more secure option. Remember the key distinction: full tunnel means all traffic goes through the corporate gateway, while split tunnel lets local internet traffic escape. A helpful memory tip is to think of “full tunnel” as a security blanket that covers every packet, whereas “split tunnel” leaves the blanket open for non-corporate traffic.
220-1102 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 system administrator configures a new VPN server for remote employees. The requirement is that all traffic from the remote user's device must be routed through the corporate network to enforce security policies. Which VPN protocol setting should the administrator enable?
Why wrong: Split tunneling would allow non-corporate traffic to go directly to the internet, bypassing security policies, which is the opposite of what is needed.
B
Disable split tunneling
Disabling split tunneling forces all traffic through the VPN tunnel, ensuring all traffic is subject to corporate security controls.
C
Use PPTP instead of L2TP
Why wrong: The choice of protocol (PPTP vs L2TP) affects encryption and compatibility, not whether all traffic is routed through the VPN.
D
Increase the MTU size
Why wrong: MTU size affects packet fragmentation and performance, not the routing of traffic through the VPN.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Disable split tunneling
Disabling split tunneling ensures that all traffic from the remote user's device is routed through the corporate VPN tunnel, enforcing security policies such as content filtering and intrusion detection. When split tunneling is enabled, only traffic destined for the corporate network goes through the VPN, while internet-bound traffic bypasses it, violating the requirement. This setting is typically configured in the VPN client or server profile (e.g., using the 'DisableSplitTunneling' registry key on Windows or the 'tunnel-all' directive in OpenVPN).
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 misconception that the choice of VPN protocol (PPTP vs. L2TP) determines traffic routing behavior, when in fact split tunneling is a separate policy setting that must be explicitly enabled or disabled.
Detailed technical explanation
How to think about this question
Under the hood, disabling split tunneling modifies the routing table on the remote device so that the default gateway (0.0.0.0/0) points to the virtual VPN interface, forcing all outbound packets through the encrypted tunnel. In real-world scenarios, this is critical for compliance with regulations like PCI-DSS or HIPAA, where all traffic must be inspected by corporate security appliances. A subtle behavior is that disabling split tunneling can cause issues with local network resources (e.g., printers) unless the VPN supports local LAN access exceptions.

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.
