Troubleshooting Intermittent Connectivity Issues with Database Access

Joe, a user, reports intermittent connectivity issues, but a technician notices that the only time Joe has issues is when he is logged into the database.

Losing connection after authenticating to a database, but still having access to network resources such as file/print services and email, would MOST likely be caused by:

A.

an incorrect DHCP gateway setting

B.

a duplicate IP address

C.

NTP synchronization

D.

ACL configuration.

D.

The issue being reported by Joe is intermittent connectivity, which suggests that the problem is not constant but occurs from time to time. The technician has identified that the only time Joe has issues is when he is logged into the database. This means that the issue is likely related to the database access.

From the given options, the one that best fits the scenario is ACL configuration. An Access Control List (ACL) is a set of rules that defines the permissions and restrictions for network traffic. If the ACL is not configured properly, it may block access to the database or interfere with the traffic that is necessary for accessing the database. This can cause the intermittent connectivity issues that Joe is experiencing.

An incorrect DHCP gateway setting could potentially cause connectivity issues, but it would likely affect all network resources, not just the database. A duplicate IP address could cause connectivity issues as well, but it would be a constant issue and not intermittent. NTP synchronization, which is the process of ensuring that all devices on a network have the same time, is unlikely to cause the connectivity issues that Joe is experiencing.

In conclusion, based on the symptoms described in the scenario, the most likely cause of Joe's intermittent connectivity issues when accessing the database is an ACL configuration problem.
