A. Each vFC interface must be bound to an FCoE-enabled Ethernet or EtherChannel interface or to the MAC address of a remotely connected adapter 

B. Each FC interface must be bound to an FCoE-enabled Ethernet or EtherChannel interface or to the MAC address of a remotely connected adapter 

C. Each vFC interface must be bound to an FC enabled Ethernet or EtherChannel interface or to the MAC address of a remotely connected adapter 

D. Each vFC interface must be bound to an FCoE-enabled vFC or EtherChannel interface or to the MAC address of a remotely connected adapter 

Answer:

Q4. Which statement about implementation of Cisco TrustSec on Cisco Nexus 5546 or 5548 switches are true?

Which three statements about the Cisco Nexus 7000 switch are true? (Choose three.) 

A. An emulated switch ID must be unique when the vPC+ feature is used. 

B. Switches with FabricPath and vPC+ consume two switch IDs. 

C. Emulated switch IDs must be numbered from 1 to 99. 

D. Each switch ID must be unique in the FabricPath topology. 

E. Switch IDs must be configured manually. 

Answer: BDE 

Q7. Which statement about scalability in Cisco OTV is true? 

A. The control plane avoids flooding by exchanging MAC reachability. 

B. IP-based functionality provides Layer 3 extension over any transport. 

C. Any encapsulation overhead is avoided by using IS-IS. 

D. Unknown unicasts are handled by the authoritative edge device. 

Answer:

Q8. Which two statements about SAN zoning on Cisco Nexus switches are true? (Choose two.) 

A. Zoning is enforced by examining the destination ID field. 

B. Devices can only belong to one zone. 

C. Only one zone set can be activated at any time. 

D. A zone can only be a member one zone set. 

E. Zoning must be administered from the primary SAN switch in the fabric. 

F. Zone configuration changes are nondisruptive. 

Answer: CF 

Q9. Which statement about RADIUS configuration distribution using Cisco Fabric Services on a Cisco Nexus 7000 Series Switch is true? 

A. Cisco Fabric Services does not distribute the RADIUS server group configuration or server and global keys. 

B. Enabling Cisco Fabric Services causes the existing RADIUS configuration on your Cisco NX-OS device to be immediately distributed.

A. STP must run inside the FP network. 

B. All VLANs must be in the same mode, CE, or FP. 

C. FP port can join the private and nonprivate VLANs. 

D. Only F and M series modules can run FabricPath. 

E. These require an enhanced Layer 2 license to run. 

Answer: BE 

Q11. A Cisco Nexus 2000 Series Fabric Extender is connected to two Cisco Nexus 5000 Series switches via a vPC link. After both Cisco Nexus 5000 Series switches lose power, only one switch is able to power back up. At this time, the Cisco Nexus 2000 Series Fabric Extender is not active and the vPC ports are unavailable to the network. 

Which action will get the Cisco Nexus 2000 Series Fabric Extender active when only one Cisco Nexus 5000 Series switch is up and active? 

A. Move the line from the failed Cisco Nexus 5000 Series switch to the switch that is powered on, so the port channel forms automatically on the switch that is powered on. 

B. Shut down the peer link on the Cisco Nexus 5000 Series switch that is powered on. 

C. Configure reload restore or auto-recovery reload-delay on the Cisco Nexus 5000 Series switch that is powered on. 

D. Power off and on the Cisco Nexus 2000 Series Fabric Extender so that it can detect only one Cisco Nexus 5000 Series switch at power up. 

Answer:

B. Dynamic vNICs can only be bound to the service profile through an updating template. 

C. Dynamic vNICs are bound directly to a service profile. 

D. Dynamic vNICs are assigned by binding a port profile to the service profile. 

Answer:

Q13. Which three items must be configured in the port profile client in Cisco UCS Manager? (Choose three.)
