Which of the following is an advantage of using a disconnected access model?

The advantage of using a disconnected access model is primarily its scalability. In this model, applications can operate independently from a central database server, allowing users to continue working with data even when connectivity to the database is temporarily lost. This approach reduces the load on the database server since multiple clients can perform operations locally rather than requiring constant, direct interactions with the server.

When applications are designed to work in a disconnected manner, they can handle data locally, synchronize changes back to the server when a connection is available. This not only allows for efficient data processing across multiple users but also enables the application to scale better, as it can accommodate more users without significantly increasing the burden on the database infrastructure.

The other options highlight downsides or limitations associated with other models rather than advantages of the disconnected access model, further underscoring why scalability stands out as a key benefit.
