Arrange the Fibre Channel (FC) SAN implementation tasks in the order they should be performed to build a redundant FC SAN. Step 1 Step 2 Step 3 Step 4 Step 5

1) Install two Fiber Channel host bus adapters in each server that will access the shared storage on the SAN. 2) Deploy two FC switches. 3) Using fiber optic cables, connect each server to each FC switch by connecting one FC HBA to one FC switch and the other FC HBA to the other FC switch. 4) Deploy the shared storage devices, such as an external RAID device containing multiple hard disk drives and two FC HBAs. 5) Using fiber optic cables, connect each storage device to each FC switch by connecting one FC HBA to one FC switch and the other FC HBA to the other FC switch.

Drag each description on the left to the appropriate switch attack type on the right. 1. ARP spoofing/poisoning 2. Dynamic Trunking Protocol 3. MAC flooding 4. MAC spoofing

1. The source device sends frames to the attacker's MAC address instead of to the correct device. 2. Should be disabled on the switch's end user (access) ports before implementing the switch configuration in to the network. 3. Causes packets to fill up the forwarding table and consumes so much of the switch's memory that it enters a state called fail open mode. 4. Can be used to hide the identity of the attacker's computer or impersonate another device on the network.
