Which of the Following Is a WSUS Server That Downloads Updates From Another WSUS Server?
A downstream WSUS server is the one that downloads updates from another WSUS server. This setup is commonly used in larger organizations or networks where a central WSUS server is responsible for downloading updates from Microsoft and distributing them to multiple downstream servers. The downstream servers then deliver these updates to the client computers within their respective subnets.
FAQs:
1. Why would I need a downstream WSUS server?
Having a downstream WSUS server offers several benefits. It reduces the bandwidth usage on the central server by distributing the update downloads across multiple servers. It also improves the update deployment process by providing localized update distribution to different subnets, ensuring faster and more efficient updates.
2. Can a downstream WSUS server download updates directly from Microsoft?
No, a downstream WSUS server cannot directly download updates from Microsoft. It relies on the central WSUS server to fetch updates from Microsoft and then downloads them from the central server.
3. How does a downstream WSUS server communicate with the central server?
The downstream WSUS server communicates with the central server using the Microsoft Update Protocol (MSUP). The central server sends a list of available updates to the downstream server, which then requests the required updates from the central server.
4. Can a downstream WSUS server approve updates independently?
No, the downstream WSUS server cannot independently approve updates. The central server is responsible for approving updates, and the downstream server inherits these approvals. However, you can customize which updates are synchronized to the downstream server.
5. Can a downstream WSUS server synchronize with multiple central servers?
Yes, a downstream WSUS server can synchronize with multiple central servers. This allows organizations with multiple WSUS servers to distribute updates efficiently across their network.
6. What happens if the central server is offline?
If the central server is offline, the downstream WSUS server will not be able to fetch new updates. However, the downstream server will continue to serve the previously downloaded updates to the client computers until the central server is back online.
7. Can a downstream WSUS server decline updates independently?
No, a downstream WSUS server cannot decline updates independently. The central server is responsible for declining updates, and the downstream server inherits these declinations.
