A network administrator is configuring a new switch for the office. The switch needs to support two VLANs: one for the office's general devices $($VLAN $10)$ and another for the security cameras $($VLAN $20).$ The administrator assigns ports $1-24$ for VLAN $10$ and ports $25-48$ for VLAN $20.$

After configuration, a security camera connected to port $26$ cannot communicate with a server on port $5.$
