156-315.81.20 Advanced VPN Design Practice Question
An organization is deploying a large-scale Remote Access VPN. To optimize performance and reduce gateway load, what is the recommended approach for distributing traffic?
⚠ Common exam trap
Candidates often confuse 'Split Tunneling' with 'Office Mode'. They think assigning an IP address (Office Mode) is the primary way to optimize bandwidth, rather than offloading internet traffic via Split Tunneling.
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
✓
Enable Split Tunneling for internet-bound traffic.
In large-scale deployments, the gateway can become a bottleneck if all traffic flows through it. Utilizing 'Split Tunneling' allows the client to send traffic destined for the corporate network over the encrypted VPN tunnel, while directing internet-bound traffic directly through the local ISP. This reduces the load on the gateway's CPU and bandwidth, improving the overall user experience and connection stability during peak business hours.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Force all traffic through the VPN tunnel (Force All Tunneling).
Why it's wrong here
Force All Tunneling directs every packet through the gateway. While it provides centralized security inspection, it significantly increases bandwidth consumption and gateway resource usage. This is not an optimization strategy; rather, it is a security posture that creates potential performance bottlenecks in large user base scenarios.
- ✓
Enable Split Tunneling for internet-bound traffic.
Why this is correct
Split Tunneling offloads non-corporate traffic from the VPN gateway, allowing direct internet access from the client's local network. This significantly reduces the processing overhead on the gateway and preserves corporate bandwidth for essential internal resources, which is a best practice for scaling remote access deployments.
- ✗
Assign a dedicated interface for each remote user session.
Why it's wrong here
Assigning dedicated interfaces is not possible or practical in modern VPN architectures. Remote access sessions are logical connections managed by the VPN process, not physical or virtual interface allocations. This approach would not scale, as physical hardware limits would be hit almost immediately upon deployment.
- ✗
Set the VPN timeout to a very low value.
Why it's wrong here
Reducing VPN timeouts would cause frequent disconnects, leading to a poor user experience and increased load on the gateway as clients continuously attempt to re-authenticate. This does not optimize traffic distribution; it only increases the administrative burden and negatively impacts the stability of the VPN environment.
