Introducing Cisco Data Center Networking (DCICN) — Question 30

Which two statements about configuring VLANs on the Cisco Nexus 7000 platform are true? (Choose two.)

Answer options

• A. Software updates are disruptive to VLANs.
• B. VLANs with the same number are unique to their VDC.
• C. VLAN licensing is required for use.
• D. To change VLAN information, the administrator must be at the switch (config) # prompt.
• E. The command copy running-config startup-config will save changes to the VLAN database.

Correct answer: B, E

Explanation

Option B is correct because VLANs with the same identifier are indeed unique to their respective Virtual Device Contexts (VDCs) on the Nexus 7000. Option E is also correct as the command mentioned saves the current configuration to the startup configuration, ensuring VLAN settings are retained. Options A, C, and D are incorrect; software updates do not disrupt VLANs, VLAN usage does not require separate licensing, and VLAN information can be modified from various modes, not solely from the (config) # prompt.
