Cloud storage platforms—such as OneDrive, Google Drive, and Dropbox—use synchronization to ensure that files updated on one device automatically update on all connected devices. CompTIA A+ defines synchronization as a key cloud characteristic that keeps local folders and cloud-stored versions consistent, enabling seamless multi-device collaboration.

Synchronization allows users to:

Modify files offline and have them sync once online

Access identical data on laptops, desktops, and mobile devices

Ensure real-time updates across multiple users or clients

Maintain version consistency and conflict resolution

A network share (A) is local to an organization and does not automatically sync across devices. Availability (C) relates to uptime and reliability, not file updates. Metered utilization (D) refers to cloud billing models where usage is tracked, not data syncing.

Thus, synchronization is the capability that ensures local folders update dynamically whenever changes occur.

An IP address starting with169.254.x.xis aself-assigned address(also calledAPIPA– Automatic Private IP Addressing). It’s used when a client device cannot contact a DHCP server. This address allows limited communication on the local network segment butno internet access.

Option A:DHCP reservations assign specific IPs from the DHCP server they don’t result in APIPA.

Option B:Dynamic assignment from DHCP assigns valid IPs in the proper subnet, not 169.254.x.x.

Option D:Static IPs are manually set and would not fall in the 169.254.x.x range unless set incorrectly.
