200-150 · Question #3
Which two statements about configuring VLANs on the Cisco Nexus 7000 platform are true? (Choose two.)
The correct answer is B. VLANs with the same number are unique to their VDC. E. The command copy running-config startup-config will save changes to the VLAN database. On the Cisco Nexus 7000, each VDC maintains an independent VLAN namespace, and VLAN configuration is stored in the running config and saved with the standard copy command.

Why each option
On the Cisco Nexus 7000, each VDC maintains an independent VLAN namespace, and VLAN configuration is stored in the running config and saved with the standard copy command.
The Nexus 7000 supports In-Service Software Upgrade (ISSU), which allows software updates without disrupting active VLANs or traffic forwarding.
On the Nexus 7000, Virtual Device Contexts partition the physical switch into multiple logical devices, each with its own isolated VLAN database. A VLAN number configured in one VDC is completely independent from the same VLAN number in another VDC, allowing VLAN ID reuse across VDCs.
VLAN functionality on the Nexus 7000 is included with the base NX-OS software and does not require a separate VLAN license.
VLAN configuration on the Nexus 7000 can be performed from the global config prompt or from VLAN-specific sub-modes; it is not restricted exclusively to the global (config)# prompt.
Unlike legacy Cisco IOS platforms that stored VLAN information in a separate vlan.dat file, the Nexus 7000 running NX-OS integrates VLAN configuration into the standard running configuration. Therefore, copy running-config startup-config saves all VLAN changes along with the rest of the device configuration.
