OSPF Network Configuration

In this scenario, you are required to configure OSPF (Open Shortest Path First) routing protocol on a network consisting of four routers. Each router is connected to two other routers using point-to-point links. You must ensure that all routers are able to communicate with each other, and that the network is stable and resilient.

VLAN Configuration

In this scenario, you are required to configure VLANs (Virtual Local Area Networks) on a switch. The switch has eight ports, and you must configure four VLANs, each with two ports. You must ensure that all VLANs are able to communicate with each other, and that there are no security vulnerabilities in the network.

Access Control Configuration

In this scenario, you are required to configure access control on a router. You must create a security policy that restricts access to the network based on user roles and privileges. You must ensure that unauthorized users are unable to access sensitive information or perform unauthorized actions.

VPN Configuration

In this scenario, you are required to configure a VPN (Virtual Private Network) between two remote offices. Each office has a router connected to the internet, and you must configure the routers to establish a secure VPN tunnel between them. You must ensure that all traffic passing through the VPN tunnel is encrypted and secure.
