Review: Data Access and Management

Which cloud storage service is included with a Microsoft 365 subscription?

• Google Drive

• Dropbox

• ICloud

• OneDrive

Answer explanation

OneDrive is Microsoft's cloud storage service bundled with Microsoft 365. Google Drive, Dropbox, and iCloud are competing services from different vendors.

What is the main purpose of cloud collaboration features in services like OneDrive or Google Drive?

• Automatically encrypting local hard drives

• Eliminating the need for any local storage

• Letting multiple users edit shared files in real time

• Installing and running apps on remote servers

Answer explanation

Cloud collaboration lets multiple users open and edit the same file simultaneously. Encryption and remote app hosting are separate services unrelated to collaboration.

A user needs OneDrive files available when their laptop has no internet connection. Which feature should they enable?

• Mapped network drive access

• Offline sync via Files On-Demand

• BitLocker full-drive encryption

• Remote Desktop connection setup

Answer explanation

Offline sync caches selected files locally so they open without a connection. A mapped network drive still requires active network access to function.

How does a hosted virtual machine differ from a local virtual machine?

• Local VMs support only Linux operating systems

• Hosted VMs run on a provider's remote servers

• Local VMs always require a paid cloud subscription

• Hosted VMs cannot run any guest operating system

Answer explanation

Hosted VMs live on a cloud provider's infrastructure, while local VMs run on the user's own machine. Local VMs support many operating systems without a cloud subscription.

When a file is shared from OneDrive with "view only" permission, the recipient can:

• Edit and rename the file freely

• Change sharing permissions for others

• Open and read the file but not change it

• Delete the original from the owner's drive

Answer explanation

View-only grants read access without edit, delete, or re-share rights. Edit access would be a separate permission level.

Which TWO permissions are part of NTFS basic permissions on a folder? (Select all that apply)

• Compress

• Modify

• Send as

• Read & execute

• Broadcast

Answer explanation

Modify and Read & execute are standard NTFS basic permissions. The other choices are not NTFS permission entries.

A user has Read share permission and Modify NTFS permission on the same folder accessed over the network. What is the effective permission?

• Read

• Modify

• Full Control

• No access at all

Answer explanation

When share and NTFS permissions combine over the network, the most restrictive applies. Read is more restrictive than Modify, so the effective permission is Read.

Which command-line tool is commonly used to map a network drive in Windows?

• Netstat

• Diskpart

• Ipconfig

• Net use

Answer explanation

The net use command assigns a drive letter to a shared network folder. The other commands handle IP, connections, and disks.

A file is moved from one folder to another folder on the SAME NTFS volume. What happens to its permissions?

• They keep their original explicit permissions

• They convert to share-level permissions

• They are reset to default inherited permissions

• They are removed entirely until reassigned

Answer explanation

Moving within the same NTFS volume preserves the original permissions. Copying, or moving across volumes, causes the file to inherit the destination folder's permissions instead.

An administrator cannot access a folder because the previous owner removed all permissions before leaving. What should the administrator do?

• Reformat the volume to clear all permissions

• Disable User Account Control to bypass the block

• Delete the folder and restore it from backup

• Take ownership of the folder, then reassign permissions

Answer explanation

Administrators can take ownership of orphaned folders and then grant new permissions. Reformatting or deleting destroys data, and disabling UAC does not resolve an ownership issue.
