NEW QUESTION 8
Which component of a Cisco Nexus 1000V Series switch is responsible for propagating configurations to virtual switches?

• A. SUP
• B. FEX
• C. VSM
• D. VEM

Answer: C

Explanation: Product Architecture
The Cisco Nexus 1000V Series Switch has two major components (Figure 1): the virtual Ethernet module (VEM), which runs inside the hypervisor, and the virtual supervisor module (VSM), which manages the VEMs.
Virtual Supervisor Module
The Cisco Nexus 1000V Series VSM controls multiple VEMs as one logical modular distributed virtual switch. Configuration is performed through the VSM and is automatically propagated to the VEMs.

Which two options are advantages when using NPIV? (Choose two.)

• A. allows a single physical N-Port to have single WWPNs, and therefore single N-Port IDs, associated with it
• B. NPIV-enabled physical N-Port can subsequently issue additional commands to register more WWPNs and receive more N-Port IDs (one for each WWPN).
• C. allows a 'single' physical N-Port to have multiple WWPNs, and therefore multiple N-Port IDs, associated with it
• D. NPV-enabled physical N-Port can subsequently issue additional commands to register more WWPNs and receive more N-Port IDs (one for each WWPN).
• E. allows 'multiple' single physical N-Port to have multiple WWPNs, and therefore multiple N-Port IDs, associated with it
• F. N-Port on the physical host would have only a single WWPN (and N-Port ID).
