A network engineer wants to configure switch ports on Cisco Nexus 2000 and 2200 Fabric Extender switches that are connected to a Cisco Nexus 5500 Series Switch. Which two options allow this…
The correct answer is B. Connect to a Cisco Nexus 5600 using Telnet, then configure the FEX switch ports. E. Connect to a Cisco Nexus 5500 switch using SSH, then configure the FEX switch ports. Cisco Nexus Fabric Extender (FEX) switches, like the 2000/2200 series, act as remote line cards for a parent Nexus switch and are configured exclusively from the parent.
Question

Why each option
Cisco Nexus Fabric Extender (FEX) switches, like the 2000/2200 series, act as remote line cards for a parent Nexus switch and are configured exclusively from the parent.
Cisco Nexus FEX devices do not have their own management plane or configurable interfaces for direct Telnet access; they are centrally managed by the parent switch.
Connecting to a Cisco Nexus 5600 (a valid parent switch for FEX) via Telnet (though insecure) allows configuration of the FEX switch ports, as the FEX is managed through the parent.
Cisco Nexus FEX devices do not have their own management plane or configurable interfaces for direct SSH access; all configuration is done via the parent Nexus switch.
Cisco Nexus FEX devices cannot be configured directly via a console cable; they function as extensions of their parent switch and inherit configuration from it.
Connecting to a Cisco Nexus 5500 switch (a valid parent switch for FEX) using SSH provides secure remote access to configure the associated FEX switch ports, as FEX management is centralized on the parent.
