Implementing and Configuring Cisco Identity Services Engine (SISE) — Question 70

A network engineer is configuring Cisco TrustSec and needs to ensure that the Security Group Tag is being transmitted between two devices.
Where in the Layer 2 frame should this be verified?

Answer options

• A. payload
• B. 802.1 AE header
• C. CMD field
• D. 802.1Q field

Correct answer: C

Explanation

The correct answer is C, as the CMD field is specifically used for carrying the Security Group Tag in Cisco TrustSec configurations. The other options, such as the payload, 802.1 AE header, and 802.1Q field, do not contain the Security Group Tag information.
