300-170 · Question #113
Refer to the exhibit. Which description of the state of the m-band management configuration is true?
The correct answer is B. VLAN 10 is the m-band management VLAN. Assuming 'm-band' refers to in-band management and the exhibit shows a corresponding configuration, VLAN 10 is configured as the dedicated VLAN for in-band management traffic.

Why each option
Assuming 'm-band' refers to in-band management and the exhibit shows a corresponding configuration, VLAN 10 is configured as the dedicated VLAN for in-band management traffic.
A contract named 'default' is not automatically consumed by an in-band management EPG; specific contracts must be defined or applied based on policy.
Based on the exhibit (which is not provided but implied by the question), VLAN 10 is explicitly configured or designated as the management VLAN for in-band management purposes, separating management traffic from data traffic.
The statement 'In-band management is functional' is a conclusion, not a direct description of the configuration's state related to a specific VLAN, and cannot be confirmed without further operational details from the exhibit.
An in-band management EPG requires a bridge domain to be associated with it to provide Layer 2 connectivity, so stating 'A bridge domain was not assigned' would contradict a functional in-band setup, unless explicitly shown in the exhibit.
