Selected Answer: A

I believe A is the correct answer. This question appears to be calling out NDAC which uses EAP-FAST. It's not B because SGT mappings don't have anything to do with devices authenticating to each other. It's not C because I don't think there is a device alias concept in TrustSec It's not D because this command doesn't exist as far as I can tell.

I go with A. Device# cts credentials id device-id password password Specifies the Cisco TrustSec device ID and password for this switch to use when authenticating with other Cisco TrustSec devices with EAP-FAST. The device-id argument has a maximum length of 32 characters and is case sensitive. https://www.cisco.com/c/en/us/td/docs/switches/lan/trustsec/configuration/guide/trustsec/ident-conn_config.html

I don't think this is correct. The question implies this is done with 'However, after this is complete' - because the last sentence says 'you have to use a username and password'. Personally I'm going with A
