Refer to the exhibit. An administrator had the above configuration working with SSL protocol, but as soon as the administrator specified IPsec as the primary protocol, the Cisco AnyConnect client…
The correct answer is C. If you specify the primary protocol as IPsec, the User Group must be the exact name of the connection profile (tunnel group). When Cisco AnyConnect uses IPsec as the primary protocol, the User Group field in the client profile must exactly match the tunnel group name on the ASA, unlike SSL which can use group URLs for lookup.
Question
Options
- AIPsec will not work in conjunction with a group URL.
- BThe Cisco AnyConnect implementation does not allow the two group URLs to be the same. SSL does allow this.
- CIf you specify the primary protocol as IPsec, the User Group must be the exact name of the connection profile (tunnel group).
- DA new XML profile should be created instead of modifying the existing profile, so that the clients force the update.

Why each option
When Cisco AnyConnect uses IPsec as the primary protocol, the User Group field in the client profile must exactly match the tunnel group name on the ASA, unlike SSL which can use group URLs for lookup.
IPsec is not incompatible with a group URL in general; the problem is specifically that IKEv2 requires an exact tunnel group name match in the User Group field, not that group URLs cannot coexist with IPsec configurations.
The restriction is not about two group URLs being identical; the core issue is that IPsec/IKEv2 uses the User Group as a literal tunnel group name, not a URL-based selector.
With IPsec/IKEv2, AnyConnect uses the User Group value to identify the correct tunnel group on the ASA by its exact configured name, because IKEv2 does not support group URL-based tunnel group selection the way SSL/TLS does. If the User Group does not precisely match the tunnel group name, the ASA cannot map the client to the correct connection profile, causing the connection to fail. Changing from SSL to IPsec without updating this value is the specific misconfiguration shown in the exhibit.
Creating a new XML profile is unnecessary; the fix requires only correcting the existing profile's User Group field to exactly match the tunnel group name on the ASA.
Concept tested: AnyConnect IPsec User Group must match tunnel group name
