Exam MD-101 topic 2 question 27 discussion

Would assume that since it didn't state that Site 1 separates the two Subnets it has with different NATs that it is NATing for both with the same public address. So answer A would be the best answer as both Subnet A and B would be behind the same NAT.

Download mode option : LAN (1=Default) This default operating mode for Delivery Optimization enables peer sharing on the same network. The Delivery Optimization cloud service finds other clients that connect to the Internet using the same public IP as the target client. These clients then try to connect to other peers on the same network by using their private subnet IP. https://docs.microsoft.com/en-us/windows/deployment/update/waas-delivery-optimization-reference

A the default is peer to peer behind the same NAT.

D. any computer on the network. Since Delivery Optimization is enabled and there is no specific restriction mentioned regarding update sources, Computer1 will download updates from any computer on the network. Delivery Optimization utilizes peer-to-peer sharing, allowing Windows 10 computers to download updates from other computers on the same local network or from the internet. Therefore, Computer1 will download updates from any computer on the network, not limited to a specific site or subnet.

Same subnet only brow. To communicate different subnets you will need at least a Routing table

Never specified any changes. Default is used. Same subnet only. LAN (1 – Default) This default operating mode for Delivery Optimization enables peer sharing on the same network. The Delivery Optimization cloud service finds other clients that connect to the Internet using the same public IP as the target client. These clients then try to connect to other peers on the same network by using their private subnet IP.

How to Enable Delivery Optimization in Windows 10 or 11? Delivery Optimization is enabled in all Windows 10 (build 1511 and newer) and Windows 11 versions. By default, it is allowed to get files from the computers in the current local network (LAN) only. Reference link: https://woshub.com/using-windows-update-delivery-optimization/

C, By default, Delivery Optimization is configured to download updates from other devices on the local network, as well as from Microsoft servers. This means that Computer1 will download updates from other computers in SubnetA, as well as from Microsoft servers. It will not download updates from computers in other sites or subnets. Therefore, the correct answer is C: the computers in SubnetA only.

In my opinion, you would expect a site to be a location which shares an external IP, and where the subnets are typically able to inter-communicate freely. By that logic, and the rules of the default LAN Mode which are referenced in other comments here - the answer would be A.

The answer is C it's LAN only not domain

not enough information what kind of question is this?

I think C is the right answer

It is D: https://docs.microsoft.com/en-us/windows/deployment/do/waas-delivery-optimization-reference#download-mode LAN Mode= Default This default operating mode for Delivery Optimization enables peer sharing on the same network. The Delivery Optimization cloud service finds other clients that connect to the Internet using the same public IP as the target client. These clients then try to connect to other peers on the same network by using their private subnet IP.

C. See MZONDERL's answer. He's right. https://docs.microsoft.com/en-us/windows/deployment/do/waas-delivery-optimization-reference#download-mode https://techcommunity.microsoft.com/t5/windows-it-pro-blog/delivery-optimization-scenarios-and-configuration-options/ba-p/280195

A. the computers in Site1 only.

download mode for delivery optimization is not specify so : LAN (1 – Default) This default operating mode for Delivery Optimization enables peer sharing on the same network. The Delivery Optimization cloud service finds other clients that connect to the Internet using the same public IP as the target client. These clients then try to connect to other peers on the same network by using their private subnet IP.

https://support.microsoft.com/en-us/windows/windows-update-delivery-optimization-and-privacy-bf86a244-8f26-a3c7-a137-a43bfbe688e8 It's my thinking that because the question only states that Delivery Optimization is enabled, that would leave it in its default state. i.e. PCs on my local network. That would mean it can only download from it's own local subnet.
