Exam MD-100 topic 5 question 30 discussion

A sounds like a better answer.

The give you the number of computers in the Branch Office, they Do not mention a server. Hosted cache mode comes from a server. Since they did not say there is a server, and the mention PEERS, its answer A

Just turn off Delivery Optimization

Windows Update -> Advanced Options -> Delivery Optimization -> Disable 'Allow downloads from other PC's'

No doubts about C The branch office server is implicit in this question. 1 - designed to reduce WAN link utilization. 2 - improve application responsiveness for branch office workers who access content from servers in remote locations. 3 - Branch office client computers use a locally maintained cache of data to reduce traffic over a WAN link. 4 - The cash can be housed on a server in the branch (Hosted Cache mode). 5 - Content can only be decrypted using the identifiers provided by the content server in the main office. 6 - If a client computer cannot locate content on the Hosted Cache server, it returns to the server in the main office and requests a download. https://learn.microsoft.com/en-us/previous-versions/windows/it-pro/windows-7/dd637832(v=ws.10)

A sounds like the best answer.

A is my vote. Branch Cache is a bandwidth optimization feature. The scenario does say WAN link, but not that the link speed is limited. It only specifies not downloading from peers.

I mean you want DO turned off for sure as you don't want the computers storing updates on their hard drives. You're also routing your internet through a WAN connection so having 25 devices reaching out through that WAN seems undesireable. Hosted cache will keep the data on a specified device and protect the WAN from saturation. I think C: is more right but with DO enabled by default in LAN mode I'm not entirely sure.

Correct C. The link provided explains that: Distributed Cache mode operates like the Delivery Optimization feature in Windows client. In Hosted Cache mode, designated servers at specific locations act as a cache for files requested by clients in its area instead of peer-to-peer distribution. This link has an excellent explanation with a picture: https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-7/dd637832(v=ws.10)#hosted-cache-mode

The answers provided here have left me a bit confused, so I did some research. BranchCache is scoped by AD Site, so there's no option to filter by subnet. The distributed mode is out of the quesiton, due to the fact that all devices in the branch office have low disk space. What you could do, is use a cache server in your main office, and receive the updates from there. While this might do the trick, turning of delivery optimization seems the obvious solution.

The Correct Answer is A.

There are 25 computers in branch offices, if you don't want to configure it one by one, and make it as a one time configuration , then C it better , you just set a new GPO.

Answer A : delivery optimisation > turn Off Peer Option, then computer download content from Main Office and not from other computers . We don't want thay because "THEY HAVE SMALL HARD DRIVE" ...easy to undertsdand no ? why so much questions ???

According to : https://docs.microsoft.com/en-us/windows-server/networking/branchcache/branchcache and specifically this: At branch offices, content is stored either on servers that are configured to host the cache or, when no server is available in the branch office, on client computers that are running Windows 10, Windows 8.1, Windows 8 or Windows 7. After a client computer requests and receives content from the main office and the content is cached at the branch office, other computers at the same branch office can obtain the content locally rather than downloading the content from the content server over the WAN link. Then A. is the best answer

Answer should be 'A'. As under Delivery Optimization, you get this option turn on or off "Allow downloads from other PCs"

it should be "A: for the answer..
