When an administrator places an endpoint into bypass mode, VMware Carbon Black Cloud Endpoint Standard will not provide any protection to the endpoint. Bypass mode is a feature that allows the administrator to disable all policy rule enforcement on the endpoint, which means that the endpoint is not actively protected by VMware Carbon Black Cloud Endpoint Standard. The sensor will ignore any malicious or suspicious activity on the endpoint and will not log any events or send any data to the Carbon Black Cloud console. The administrator can use bypass mode to troubleshoot application interoperability, bootup, or login issues on the endpoint, or to upgrade the operating system on the endpoint. The administrator can enable or disable bypass mode from the Carbon Black Cloud console, the sensor UI, or the command line. The administrator can also view the reason and duration of the bypass mode from the Carbon Black Cloud console12.

The other options are incorrect or irrelevant. VMware Carbon Black Cloud Endpoint Standard will not be uninstalled from the endpoint when it is placed into bypass mode. The sensor will still be running on the endpoint, but it will not enforce any policy rules. VMware Carbon Black Cloud Endpoint Standard will not place the machine in quarantine when it is placed into bypass mode. Quarantine is a different feature that allows the administrator to isolate the endpoint from the network, preventing any communication with other devices or external servers. VMware Carbon Black Cloud Endpoint Standard will not apply policy rules when the endpoint is placed into bypass mode. Policy rules are the settings that define how the sensor detects and prevents threats on the endpoint. Bypass mode disables all policy rule enforcement on the endpoint. References:
