BranchCache is a wide area network (WAN) bandwidth optimization technology that is included in some editions of the Windows Server 2016 and Windows 10 operating systems, as well as in some editions of Windows Server 2012 R2, Windows 8.1, Windows Server 2012, Windows 8, Windows Server 2008 R2 and Windows 7. To optimize WAN bandwidth when users access content on remote servers, BranchCache fetches content from your main office or hosted cloud content servers and caches the content at branch office locations, allowing client computers at branch offices to access the content locally rather than over the WAN.
Use is more for offices with different branches storing different resources once accessed so that it doesn't need to be retrieved via the cloud or other medium repeatedly. Proxy servers perform a similar function for web pages visited and is the correct answer.
Exactly what I found on Microsoft website, so Branch Cache Server is the correct answer, but the thing is I've never seen this topic covered by A+. It could be one of these questions A+ add to the exam for a test purpose where it is not marked at the end!
I am saying D because the branche cache is available on the local network therefore quicker to access than the proxy server. The proxy server can cache too but the local cache is quicker than sending a request to the intermediary and waiting for a response. The proxy gets you request then sends it to the server with the data. the server sends a response to the proxy which then has to send you the response. Sending from your computer (the client) straight to the server should be faster as there is no middle man and less steps.
A proxy server is used primarily as a go-between for the client and the website accessed. It is commonly used to cache information so that another user accessing the same web page won’t have to get it from the Internet, because it already exists on the proxy server, which increases general performance and efficiency.
its proxy server;
as per A+ Exam Cram Book: "A proxy server is used primarily as a go-between for the client and the website
accessed. It is commonly used to cache information so that another user
accessing the same web page won’t have to get it from the Internet, because
it already exists on the proxy server, which increases general performance
and efficiency."
Only source content - that is, content that client computers initially obtain from a BranchCache-enabled content server - is accelerated by BranchCache. Content that client computers obtain directly from other sources, such as Web servers on the Internet or Windows Update, is not cached by client computers or hosted cache servers and then shared with other computers in the branch office.

Think it is proxy server since to cache web content the web server needs to support branch cache server and it needs to be configured. Proxy server will cache all web sites without additional software installed and configured.
The proxy server should be the correct answer. Branch Cache is not a server but a feature found in Windows OS and server.
Note: nowhere in the question mentions Window's server.
Branch Cache server is correct. It increases web query response time for clients and servers. Proxy server provides security by masking our identity on the internet
I think Proxy server is correct answer:
This is one of the definition of Branch Cache:
BranchCache caches file, web, and application content at branch office locations, allowing client computers to access data using the local area network (LAN) rather than accessing the content over slow WAN connections.
this is example of Proxy server:
For example, when a visitor accesses a blog with a header image, the proxy server looks for the image in its cache. If it’s the first time that the image is accessed, the server needs to request it from the origin. The next time the article is accessed from the proxy server – by any visitor – the image will already be available in the proxy cache.
I would have to agree with you. Although a proxy server can be configured to cache frequently requested pages, I think that the A+ would more generally want the technician to know that the DNS server is where the cache is stored. I don't remember any of the A+ content revolving around managing, or flushing, proxy caches. As compared to the material covered in troubleshooting the DNS cache.
DNS server is storing entries to an FQDN table mapping those FQDN's to IP addresses. It isn't caching ever page it encounters like a proxy server would.
I agree that it could be Proxy server, and that BanchCache Server is not covered in A+. However, Proxy server is used in Enterprise environments, where the users log-in to certain web pages, and the Proxy servers saves those websites for faster access for other users. It creates a cache. BanchCache Server is general use.
Upon research, I found out the Branchcache exists but that I know is not covered in the A+ objectives. I don't know why it's even listed as an option.
