156-215.81.20 VPN Basics Practice Question
An administrator is setting up a Remote Access VPN using Check Point Mobile Access. The administrator wants to ensure that remote users can access internal resources using the same IP address throughout their session, even if they disconnect and reconnect. Which Check Point feature should be enabled to achieve this?
⚠ Common exam trap
The trap here is assuming that Office Mode alone provides IP address persistence, when in fact it only assigns IP addresses and does not guarantee the same one on reconnection.

Correct answer & explanation
✓
IP Address Persistence
IP Address Persistence is the feature that ensures a remote user receives the same virtual IP address each time they connect, provided the address is still available. This is particularly useful for applications that require a consistent IP address for the user. Office Mode must be enabled to assign IP addresses, but IP Address Persistence is the specific setting that maintains the same address across sessions. Together, they provide a stable and consistent remote access experience.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Visitor Mode
Why it's wrong here
Visitor Mode is a Check Point feature that allows remote access clients to connect to the gateway using TCP port 443, which is useful when UDP port 500 or 4500 is blocked. It does not assign IP addresses to clients or provide IP address persistence. Visitor Mode is about traversal through restrictive networks, not about maintaining a consistent IP address for the client. Therefore, it does not meet the administrator's requirement.
- ✗
Office Mode
Why it's wrong here
Office Mode assigns a virtual IP address to remote users from a predefined pool, allowing them to access internal resources as if they were on the local network. However, Office Mode does not guarantee that the same IP address is assigned upon reconnection; the IP address may change each time the user connects. To maintain the same IP address, additional configuration such as IP address persistence is required, which is not part of Office Mode by default.
- ✗
Secure Domain Logon
Why it's wrong here
Secure Domain Logon is a feature that allows remote users to log on to their Windows domain before establishing a VPN connection, ensuring that login credentials are transmitted securely. It does not assign IP addresses or ensure IP address persistence. The administrator's goal is to maintain the same IP address across sessions, which is unrelated to Secure Domain Logon. Thus, this feature is not applicable here.
- ✓
IP Address Persistence
Why this is correct
IP Address Persistence is a feature in Check Point Remote Access VPN that ensures a remote user receives the same virtual IP address each time they connect, as long as the IP address is available. This is exactly what the administrator needs to maintain consistent access to internal resources. It works in conjunction with Office Mode, which must also be enabled to assign IP addresses. Enabling IP Address Persistence provides a stable IP for the user's session and reconnections.
