   A network team is evaluating version control systems. They have a requirement that every engineer must have a full copy of the repository history on their local machine, even if the central server is unavailable. They also need to support multiple remote repositories for redundancy. Which system best fits these requirements?

   • AA distributed system like Git with multiple remotes.
   • BA centralized system with a mirrored backup server.
   • CA distributed system but only one remote repository.
   • DA centralized system with nightly exports to a network share.

   A small network team currently uses a centralized version control system (CVCS) and is considering moving to a distributed version control system (DVCS). The team often works offline during customer site visits and needs to commit changes locally even without connectivity to the central server. Which advantage of a DVCS directly addresses this requirement?

   • AThe system automatically synchronizes all local changes to the central server in real time.
   • BThe central server stores only the latest snapshot, reducing storage requirements.
   • CEach developer has a full local repository, allowing commits and history access without a network connection.
   • DThe central server enforces a strict linear history, preventing divergent branches.
