A network administrator is designing a new office network and wants to use a topology that provides redundancy so that if one cable fails, communication can still occur via alternate paths. Which TWO topologies offer this redundancy? (Choose TWO.)
In a star, each device connects to a central switch; if a cable fails, only that device is affected, but redundancy can be achieved with redundant switches.
Why this answer
A mesh topology connects every device to every other device, providing multiple paths. A star topology with multiple connections to a switch can also provide some redundancy, but the question refers to traditional topologies. Mesh is inherently redundant.
Bus and ring do not offer redundancy; a broken cable can disrupt the entire network.

A user wants to synchronize files across multiple devices, including an iPhone, a Windows laptop, and an Android tablet. Which TWO cloud services would be most effective for this cross-platform syncing?
Works on all platforms.
Why this answer
iCloud works well across Apple devices and Windows, but not Android easily. Google Drive works on all platforms. OneDrive works on all platforms too.
But the question asks for TWO. iCloud and Google Drive are cross-platform, but iCloud has limited Android support. Actually, iCloud does not sync with Android directly. Google Drive works on all.
OneDrive works on all. So the best two are Google Drive and OneDrive. However, the stem includes iPhone, so iCloud is native but not Android.
So the answer should be Google Drive and OneDrive. But I'll reconsider: Many users use iCloud and Google Drive. However, iCloud on Android is not as seamless.
The ITF+ likely expects common cloud services: iCloud, Google Drive, OneDrive. But for cross-platform, Google Drive and OneDrive are better. I'll choose Google Drive and OneDrive.
Explanation: Both work on iOS, Windows, and Android.
