CCSM Advanced VPN Troubleshooting Practice Question
A remote access user reports that the Mobile Access VPN client connects, but internal web applications are unreachable. The administrator confirms the user authenticates successfully and receives an IP address from the Office Mode pool. Which action should the administrator take to diagnose why traffic is not reaching internal resources?
⚠ Common exam trap
The trap here is focusing on tunnel establishment or certificates when the user is already connected, instead of examining routing and policy for the Office Mode network.

Correct answer & explanation
✓
Check that the Office Mode network is included in the VPN domain and that a firewall rule permits traffic from the Office Mode pool to the internal servers.
The Mobile Access client successfully authenticated and received an Office Mode IP, which indicates the VPN tunnel is established. Connectivity to internal resources then depends on the Office Mode network being part of the VPN domain so return traffic is encrypted, and on a firewall rule permitting the Office Mode pool to reach internal servers. Checking both items resolves the typical cause of this symptom.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run 'vpn tu' on the gateway to list the IKE and IPsec SAs for the user's Office Mode IP.
Why it's wrong here
The 'vpn tu' utility displays and manages IKE and IPsec SAs, which is useful when the tunnel itself is not established. In this case the user connected and received an Office Mode address, so the tunnel is up. The problem is likely in routing or policy for the Office Mode network, not in the SA state, so listing SAs would not reveal why internal web applications are unreachable.
- ✗
Verify that the user's certificate has not expired and reissue it if necessary.
Why it's wrong here
An expired certificate would prevent the user from authenticating in the first place, but the scenario states authentication succeeded and an Office Mode IP was assigned. Certificate validity is therefore not the cause of the connectivity failure. The administrator should focus on routing and policy for the Office Mode network rather than on certificate lifecycle, which is already proven functional.
- ✗
Increase the IKE Phase 1 lifetime on the Security Gateway to prevent rekeying during the session.
Why it's wrong here
Phase 1 lifetime controls how often the IKE SA is renegotiated; it does not govern whether internal web applications are reachable. The user's tunnel is already established and stable, so extending the lifetime would not change routing or policy behavior. This action is unrelated to the symptom and could mask a rekey issue rather than resolve the actual connectivity problem for internal resources.
- ✓
Check that the Office Mode network is included in the VPN domain and that a firewall rule permits traffic from the Office Mode pool to the internal servers.
Why this is correct
When a Mobile Access client connects, it receives an Office Mode IP that must be routable to internal resources and permitted by policy. If the Office Mode network is missing from the VPN domain, return traffic is not encrypted, and if no firewall rule allows the Office Mode pool to reach internal servers, packets are dropped. Verifying both the VPN domain inclusion and the access rule addresses the most common cause of this symptom.
