An engineer is configuring posture assessment for their network access control and needs to use an agent that supports using service conditions as conditions for the assessment. The agent should be run as a background process to avoid user interruption but when it is run. the user can see it. What is the problem?

The Cisco AnyConnect client, which includes the posture module, has a graphical user interface (GUI) that is visible to the end-user by default. To meet the requirement for the agent to run as a non-intrusive background process, it must be deployed in a "stealth" mode, which hides the main GUI. This is a specific deployment configuration. The problem described—that the user can see the agent when it should be hidden—indicates that the standard version was deployed instead of the one configured for stealth operation. The stealth configuration ensures the agent only presents a UI to the user when an action, such as remediation, is explicitly required.

B. The deployment method (ISE headend versus an enterprise tool like SCCM) does not determine the agent's UI visibility; this is controlled by installation parameters within the deployment package.
C. While the agent does appear for remediation, the question implies it is visible during normal operation ("when it is run"), which violates the "background process" requirement.
D. The scenario describes a persistent background agent, not a temporary one. Furthermore, a permissions issue would likely cause the assessment to fail, not make a hidden agent visible.

1. Cisco AnyConnect Secure Mobility Client Administrator Guide, Release 4.10, "Deploy AnyConnect" section: This guide details how to customize the AnyConnect installation. For example, using command-line options like vpngui -stealth can hide the AnyConnect GUI. The documentation states, "To hide the AnyConnect GUI from the user, you can start the AnyConnect GUI from the command line with the -stealth option." This confirms the existence and purpose of a stealth mode. (Reference: "Start AnyConnect from the Command Line," Chapter: "Using the AnyConnect Command Line Interface").

2. Cisco Identity Services Engine Administrator Guide, Release 3.1, "Configure Client Provisioning Policies" section: This guide explains that client provisioning policies on ISE define which agent software and related profiles are delivered to endpoints. The choice of profile and installation package (which can be customized for stealth operation) determines the agent's behavior on the endpoint. The issue stems from the configuration of the provisioned agent package, not the provisioning process itself. (Reference: Chapter: "Set Up Cisco ISE for Posture Service," Section: "Client Provisioning Policies").
