A passive attack in IT security involves unauthorized monitoring and gaining access to data without altering it. This type of attack is often used for data gathering and eavesdropping, where the attacker gains access to sensitive information without modifying or disrupting the system’s operations.

RAID 1 mirrors data, meaning it duplicates the data on two disks. Therefore, to provide 250 GB of usable storage, 500 GB of total storage is required (250 GB for the primary data and 250 GB for the mirrored copy). At a cost of $2 per GB, the chargeback amount is calculated as follows:Chargeback amount=500 GB×$2/GB=$1000Chargeback amount=500GB×$2/GB=$1000

RAID 6 uses two parity blocks for data protection, allowing it to withstand the failure of two drives. In a RAID 6 array with four 250 GB disks, the usable capacity is calculated by subtracting the space used for parity. With four disks, two are used for parity, leaving the capacity of two disks for data storage. Therefore, the total usable data storage capacity is 2 * 250 GB = 500 GB.

Virtual LANs (VLANs) are used to segment a physical LAN into multiple logical LANs. This allows multiple networks to share a single physical LAN while maintaining the logical separation between the networks. Each VLAN is assigned a unique identifier and each network device is configured with the identifier of the VLAN it belongs to. This allows traffic from different VLANs to be identified and routed accordingly. VLANs provide an additional layer of security by ensuring that devices on one VLAN cannot access the traffic of another VLAN.

Implementing link aggregation in a Fibre Channel (FC) Storage Area Network (SAN) environment distributes network traffic over Inter-Switch Links (ISLs), ensuring even utilization of these links. Link aggregation combines multiple physical ISLs into a single logical link, allowing for balanced traffic distribution and improved redundancy. This helps to avoid congestion on any single ISL, thus enhancing overall network performance and reliability.
