Why each option
In a 24-bit Fibre Channel address represented as 'aabbcc' in hexadecimal, the 'bb' portion identifies the area within a switch.
The 'cc' portion of the address represents the Port ID, which identifies a specific port within an area, not the area itself.
A Fibre Channel address is a 24-bit address, typically represented in hexadecimal as 'aabbcc', where 'aa' represents the Domain ID (switch identifier), 'bb' represents the Area ID (logical area or port group within a switch), and 'cc' represents the Port ID (individual port within an area). Therefore, 'bb' specifically identifies the area.
'aabb' combines the Domain ID ('aa') and the Area ID ('bb'), but the question specifically asks for the portion identifying only the area.
'bbcc' combines the Area ID ('bb') and the Port ID ('cc'), but the question specifically asks for the portion identifying only the area.
