How can a technician use the OSI 7-layer model as a troubleshooting tool for a database issue?
What will be an ideal response?
Try a top-to-bottom or bottom-to-top OSI model approach to the problem. Sometimes it pays to try both.
7 - Application: Could there be a problem with the API that enables the database application to connect to the database server?
6 - Presentation: Could there be a problem with encryption between the application and the database server?
5 - Session: Could a database authentication failure be preventing access?
4 - Transport: Perhaps extreme traffic on the network could block an acknowledgment segment? This seems a bit of a reach, but worth considering.
3 - Network: Someone might have changed the IP address of the database server.
2 - Data Link: The MAC address of the database server or the user's machine might be blacklisted.
1 - Physical: A disconnected cable or dead NIC can make for a bad day.
