An administrator installed a Cisco ASA that runs version 9.1. You are asked to configure the firewall through Cisco ASDM.
When you attempt to connect to a Cisco ASA with a default configuration, which username and password grants you full access?
A. admin / admin
B. asaAdmin / (no password)
C. It is not possible to use Cisco ASDM until a username and password are created via the username usernamepassword password CLI command.
D. enable_15 / (no password)
E. cisco / cisco

Totally weird one. You have to set an enable password into cli at least to use ASDM.
