    1. It is possible to have full network connectivity, but the application simply cannot provide data.

    2. Another type of problem at the application layer occurs when the physical, data link, network, and transport layers are functional, but the data transfer and requests for network services from a single network service or application do not meet the normal expectations of a user.
