You are hired to conduct security testing on their network. You successfully brute-force the SNMP
community string using a SNMP crack tool. The access-list configured at the router prevents you
from establishing a successful connection. You want to retrieve the Cisco configuration from the
router. How would you proceed?

A.
Use the Cisco’s TFTP default password to connect and download the configuration file

B.
Run a network sniffer and capture the returned traffic with the configuration file from the router

C.
Run Generic Routing Encapsulation (GRE) tunneling protocol from your computer to the router
masking your IP address

D.
Send a customized SNMP set request with a spoofed source IP address in the range -192.168.1.0
