Introducing Cisco Data Center Networking (DCICN) — Question 69

Which four statements indicate unique properties of VLAN 1 on Cisco Nexus switches? (Choose four.)

Answer options

• A. VLAN 1 is used to flood multicast traffic.
• B. VLAN 1 cannot be deleted.
• C. VLAN 1 is used for Cisco Discovery Protocol.
• D. VLAN 1 is used for VTP advertisements.
• E. VLAN 1 defines a collision domain.
• F. VLAN 1 defines a broadcast domain.

Correct answer: B, C, D, F

Explanation

VLAN 1 has specific properties, such as being non-deletable, facilitating Cisco Discovery Protocol, handling VTP advertisements, and defining a broadcast domain. Options A and E are incorrect as VLAN 1 is not specifically used for flooding multicast traffic nor does it define a collision domain, which is instead a characteristic of network segments or switches.
