This is the most likely cause of preventing the users from accessing the application server because a VLAN is a logical segmentation of a network that isolates traffic based on certain criteria. If the human resources department and the application server are on different VLANs, they will not be able to communicate with each other unless there is a router or a switch that can route between VLANs.

A disaster recovery plan would be useful when trying to restore IT infrastructure operations after a non-planned interruption. A disaster recovery plan is a document that outlines the steps and procedures to recover from a major disruption of IT services caused by natural or man-made disasters, such as fire, flood, earthquake, cyberattack, etc. A disaster recovery plan typically includes:
* A list of critical IT assets and resources that need to be protected and restored
* A list of roles and responsibilities of IT staff and stakeholders involved in the recovery process
* A list of backup and recovery strategies and tools for data, applications, servers, networks, etc.
* A list of communication channels and methods for notifying users, customers, vendors, etc.
* A list of testing and validation methods for ensuring the functionality and integrity of restored systems
* A list of metrics and criteria for measuring the effectiveness and efficiency of the recovery process A disaster recovery plan helps IT organizations to minimize downtime, data loss, and financial impact of a disaster, as well as to resume normal operations as quickly as possible.
