Exam objective
Core 1 4.0: Cloud Characteristics and File Sync
Cloud Characteristics and File Sync for A+
Scope: This topic package covers the technician-level recognition and basic support implications of the cloud characteristics named in the official objective: shared versus dedicated resources, metered utilization (including ingress and egress), elasticity, availability, file synchronization, and multitenancy.

Common mistakes to avoid
Technicians often confuse "shared" with "unsecure". Shared resources can still enforce logical separation and security controls.
Students sometimes flip ingress and egress. Use the cue: ingress = in, egress = exit. Another confusion is assuming all cloud traffic is free; metered simply means tracked and possibly charged depending on provider.
Students sometimes answer 'availability' when the scenario is about scaling capacity. Emphasize the cue words: scale/auto-scaling -> elasticity; uptime/always-on/redundant -> availability.
Many learners confuse synchronization with backup. Synchronization aims to keep copies consistent; backup is intended for historical recovery and may keep multiple versions.
