The correct answer is Deploy and update Windows as a service (WaaS) to this device by using: Long-Term Servicing Channel. The Long-Term Servicing Channel (LTSC) is the correct choice for a device that lacks internet access and can only be updated manually every two years, as it provides infrequent major updates and extended support focused on stability.

Question

Hotspot Question A company uses Microsoft 365. The company has an application that runs on a device that does not have internet access. The device can only be updated manually every two years. You need to determine how you should update the device. Select the answer that correctly completes the sentence. Answer: Explantion: Long-Term Servicing Channel (LTSC) With the Long-Term Servicing Channel, a new major version of Windows Server is released every 2-3 years. Users are entitled to 5 years of mainstream support and 5 years of extended support. This channel provides systems with a long servicing option and functional stability, and can be installed with Server Core or Server with Desktop Experience installation options. Deployments of the LTSC of Windows Server are not affected by Semi-Annual Channel releases. The Long- Term Servicing Channel will continue to receive security and non-security updates, but it will not receive the new features and functionality.

Explanation

The Long-Term Servicing Channel (LTSC) is the correct choice for a device that lacks internet access and can only be updated manually every two years, as it provides infrequent major updates and extended support focused on stability.

Approach. The correct interaction is to select 'Long-Term Servicing Channel'. The scenario describes a device with critical constraints: it 'does not have internet access' and 'can only be updated manually every two years'. The Long-Term Servicing Channel (LTSC), primarily used for Windows Server and specialized embedded/IoT devices (like Windows 10 IoT Enterprise LTSC), is designed for environments requiring long-term functional stability and infrequent updates. LTSC releases a new major version every 2-3 years, offering 5 years of mainstream support and 5 years of extended support. This update cadence perfectly aligns with the manual, biennial update schedule and the need for stability without relying on continuous internet connectivity for feature updates. It ensures that the device receives critical security updates without disruptive feature changes, fitting the 'set it and forget it' nature for devices with specific application requirements and limited connectivity.

Common mistakes.

  • common_mistake. Selecting 'General Availability Channel' would be incorrect because this channel (formerly Semi-Annual Channel) is designed for frequent feature updates, typically twice a year, which is incompatible with a device updated only every two years and lacking internet access for continuous updates. Choosing 'Windows Insider Program' is incorrect as it provides pre-release builds intended for testing and development, not for stable production environments, especially for critical applications. Finally, 'Microsoft Intune' is a management solution for deploying updates and managing devices, not a servicing channel itself. Moreover, a device without internet access cannot be directly managed or receive updates via Intune's cloud-based services for update deployment. Even with on-prem update sources, Intune is the delivery mechanism, not the update channel type for Windows as a Service (WaaS).

Concept tested. Windows as a Service (WaaS) servicing channels, specifically the distinction between the Long-Term Servicing Channel (LTSC) and the General Availability Channel (GAC), and their appropriate use cases based on update frequency, stability requirements, and internet connectivity.
